Mic/Line Input & Line Output
Dante Interface
Introduction
The Model 5414 Mic/Line Input & Line
Output Interface provides a simple-to-use
yet high-performance means of interfacing
analog signals with applications that utilize
Dante® audio-over-Ethernet media network-
ing technology. Four microphone or level-
level sources can be connected to the unit
and then, after conversion to digital, output
by way of a Dante interface. Four signals
arriving by way of Dante can be converted
to analog and then output as balanced line-
level signals. A monitor section allows the
input and output signals to be selectively
observed using meters and a headphone
output.
The Model 5414 is a fully professional
product that offers the audio quality, fea-
tures, and reliability required by 24-hour
on-air and commercial applications. The
four mic/line audio inputs use standard 3-pin
female XLR connectors for easy interfac-
ing with balanced and unbalanced sources.
The input circuitry features adjustable gain,
P48 microphone power, and high-pass filter
functions. Configuration of the inputs can be
made locally by using pushbutton switches
or remotely using the STcontroller applica-
tion. The input audio signals are converted
to 24-bit digital and then transported via the
Dante interface.
Four digital audio signals can be routed to
the Model 5414 via the Dante interface and
are then converted to analog. Four 3-pin
male XLR connectors on the unit’s back
panel provide access to the balanced line-
level outputs. The monitor section provides
the user with the ability to select any input
or output signal, or signal pair, and then
observe their level via LEDs meters and
aurally monitor them by way of a 2-channel
(stereo) headphone output.
Configuration choices allow selection of the
unit’s input and output nominal operating
levels. Independent selections are provided
for the input (analog-to digital) and output
(digital-to-analog) conversion processes.
This capability ensures that the Model 5414
will integrate smoothly into Dante applica-
tions that utilize SMPTE®, EBU, and other
industry-standard nominal levels.
An Ethernet connection is all that’s required
to make the Model 5414 part of a sophisti-
cated networked audio system. Dante audio-
over-Ethernet has found wide acceptance
as an audio “backbone” due to its ease of
use, interoperability, excellent audio qual-
ity, and wide adoption by a large number
of equipment manufacturers. The Model
5414 can serve as an “edge” device for a
Dante network implementation, providing
high-performance input, output, and monitor
resources for applications that need a limited

number of channels. It can also serve as a
general-purpose “tool” to help expand Dante
capabilities to facilities and applications that
were initially implemented to support signals
in the analog domain.
For powering, the unit can be directly con-
nected to an AC mains source. A true
“universal input” design that’s intended for
worldwide use, the input voltage can range
from 100 to 240 volts, 50/60 Hz. A source
of 10 to 18 volts DC can also be connected
to power the Model 5414. If both AC and
DC sources are connected, the AC source
will power the unit while the DC source will
serve as a backup. In this way a battery can
be connected, ready to serve in a standby
capacity.
Standard connectors are used for the
audio input and output, Ethernet, DC input,
and AC mains interconnections. The unit’s
enclosure mounts in one space (1U) of a
standard 19-inch rack enclosure and weighs
less than four pounds (2 Kg).
Dante Audio-over-Ethernet
Digital audio data associated with the Model
5414 is interfaced with a local area network
(LAN) using Dante audio-over-Ethernet
media networking technology. Status LEDs
provide a real-time indication of Dante and
LAN performance. A major benefit of us-
ing Dante to transport professional audio
signals is its compatibility with standard
Ethernet network implementations, including
switches and routers. The Model 5414 sup-
ports digital audio signals with a sampling
rate of 48 kHz and a bit depth of up to 24.
This sampling rate was selected for optimal
support of broadcast, production, industrial,
and commercial applications.
The signals associated with the four mic/line
input channels are converted to digital and
then routed to transmitter (output) channels
on the Dante interface. Four transmitter
(output) channels from one or more associ-
ated Dante-enabled devices can be assigned
to the Model 5414’s receiver (input) channels
using the Dante Controller application. These
input signals are converted into analog and
then sent to the line output circuitry.
The Model 5414 is compatible with the
AES67 interoperability standard. In addition,
the unit is compatible with the Dante Domain
Manager™ (DDM) software application.
Applications
The Model 5414 is a general-purpose mic/
line input, line output, and monitoring device
intended for a variety of audio and audio-
for-picture applications that utilize Dante.
It’s suitable for use in demanding on-air
broadcast and live-event applications that
require both excellent audio performance
and reliable operation. The rack-mounted
unit is appropriate for installation in fixed
locations, serving the needs of systems
associated with stadium, worship, education,
commercial, and government facilities. Its
lightweight enclosure also makes it suitable
for mobile and field uses.
The Model 5414 features an optimized set
of controls and indicators that makes it
simple and intuitive to use. With the unit’s
metering and monitoring resources it’s easy
for operators to obtain optimal performance.
And by providing standard connectors for all
inputs and outputs, along with powering from
AC mains or 10-18 volts DC, setup can be
completed in just a few minutes.

Mic/Line Input & Line Output
Dante Interface
Mic/Line Inputs
The Model 5414 provides four analog inputs
that are compatible with microphone and
line-level signals. The mic/line input circuitry
allows the level of the connected sources to
be boosted as required, converted to digital,
and then output to an Ethernet network by
way of Dante. Each mic/line input can be
individually adjusted to meet the require-
ments posed by a wide range of sources.
The choices can be selected either locally
or by way of the STcontroller remote control
software application.
Using two DIP switches, located on the unit’s
back panel, the relationship between the
analog input level and the digital audio out-
put level can be configured. Three choices
are available which allow compatibility with
SMPTE and EBU standards as well as an-
other commonly utilized setting.
The preamplifier gain of each channel can be
selected from among 20 values: 0 dB (line),
10 dB, and 19 through 70 dB in 3-dB steps.
A source of P48 phantom power can be
enabled to power condenser microphones.
In addition, a high-pass filter (HPF) function
can be enabled as required to reduce the
presence of unwanted low-frequency content
typically associated with hum, rumble, or
wind noise.
Compatible signal sources include dynamic,
ribbon, and phantom-powered condenser
(capacitor) microphones. The extended gain
range, up to 70 dB, allows microphones
with low-sensitivity to perform correctly. The
preamplifier gain settings of 0 dB and 10 dB
were specifically included to support con-
nection of balanced and unbalanced line-
level signals that are commonly provided by
professional and semi-professional audio
equipment. Typical nominal levels for these
sources would be +4 dBu and –10 dBV,
respectively. Devices providing these analog
signal sources could include audio con-
soles, wireless microphone receivers, and
broadcast playback equipment.
An 8-segment LED meter is associated with
each of the four mic/line input channels. The
meters are calibrated in dBFS which can as-
sist users in optimizing the preamplifier gain
settings so as to provide the best possible
conversion from the analog to the digital
domain. LEDs display the on/off status of
the P48 and high-pass filter (HPF) func-
tions. For front-panel space efficiency the
four mic/line input channels share a com-
mon configuration section which includes
a 2-digit LED display and four pushbutton
switches. The LED display allows the se-
lected preamplifier gain of the mic/line input
channels to be observed. The buttons allow
rapid selection of the preamplifier gain as
well as controlling the on/off status of the
P48 phantom power and high-pass filter
(HPF) functions.
The mic/line inputs are electronically bal-
anced (differential), capacitor-coupled, and
ESD (static) protected for reliable opera-
tion in a variety of demanding applications.
Extensive filtering minimizes the chance
that radio frequency (RF) energy will cause
interference. The inputs are protected from
damage should a moderate DC voltage be
accidentally connected. The sum of these
characteristics makes the mic/line inputs
suitable for use in studio and mobile facili-
ties as well as field-deployed environments.
The four 3-pin female XLR connectors asso-
ciated with the Model 5414’s mic/line inputs
were specifically located on the front panel.
This can eliminate the need for an external
I/O or “patch” panel, allowing signal sources
and their associated interconnecting cables

to be rapidly connected as required. Rather
than being “buried” in the back of a rack en-
closure the Model 5414 provides convenient
access to the mic/line input connectors and
their associated configuration buttons, indica-
tors, and displays. “Latchless” 3-pin female
XLR connectors from Neutrik® are utilized to
improve long-term reliability. Using friction,
rather than a mechanical lock, to secure the
mating connector helps to ensure reliable
electrical connections while minimizing the
chance of connector failure.
The audio performance of the Model 5414’s
mic/line inputs is very good. Low-noise,
wide dynamic-range microphone preamplifier
circuits ensure that input audio quality is
preserved. The P48 phantom power source
is extremely low noise, allowing optimal
microphone operation and imparting little
signal degradation. The outputs of the pre-
amplifiers are routed to high-performance
analog-to-digital conversion (ADC) sections
that support a sampling rate of 48 kHz and a
bit depth of 24. A precision voltage-reference
integrated circuit helps the ADC circuitry
perform highly accurate signal conversion.
The audio signals, now in the digital domain,
are connected to the Dante interface section
where they are packetized and prepared for
transport over Ethernet.
Line Outputs
The Model 5414 provides four general-pur-
pose analog line-level output channels. Four
receiver (input) channels associated with
the unit’s Dante interface serve as the audio
sources. The Dante Controller application
software will typically be used to select the
sources which are provided by transmitter
(output) channels on associated equipment.
Using two DIP switches, located on the unit’s
back panel, the relationship between the
digital audio input level and the analog out-
put level can be configured. Three choices
are available which allow compatibility with
SMPTE and EBU standards as well as an-
other commonly utilized setting.
The line outputs are electronically balanced,
capacitor-coupled, and ESD (static) protect-
ed. High-quality components, including the
important digital-to-analog converters, are
used to provide low-distortion, low-noise,
and sonically excellent performance. Robust
circuitry provides protection from damage
should a moderate DC voltage be acciden-
tally connected, something especially useful
in broadcast applications. The line outputs
are compatible with virtually all balanced
and unbalanced loads with an impedance
of 2 k ohms or greater.
Input and Output Monitoring
A flexible yet easy-to-use monitor section
offers the ability to listen to and visually
observe the level of the audio signals that
are associated with the four mic/line input
channels and the four line output channels.
A mode configuration choice allows monitor-
ing of either a single audio channel or
a pair of audio channels. This can be valu-
able when monitoring monaural or stereo
(dual-channel) signals. A 2-channel analog
output supports the connection of a pair
of stereo headphones. For application
flexibility the headphone output can also
be interfaced with inputs on amplified loud-
speakers or a power amplifier associated
with monitor loudspeakers. A rotary control
allows the level of the headphone output to
be adjusted.
For convenience, two ¼-inch 3-conductor
(stereo) phone jacks, one located on the
front panel and one on the back panel, are
provided. The same 2-channel signal is

Mic/Line Input & Line Output
Dante Interface
routed to both the front and the back head-
phone output jacks. However, whenever
the front jack is utilized the jack on the back
panel will automatically mute. This mute
function can be useful when the jack on the
back panel is being used to interface with
inputs on loudspeaker systems. Automatic
muting of the loudspeakers will occur when-
ever a pair of headphones is plugged into
the jack on the front panel, a feature espe-
cially important for on-air applications.
Two 8-segment LED meters display the
level of the signal or signals that are select-
ed for monitoring. The meters are calibrated
relative to the digital domain (dBFS), directly
reflecting the signal level in the Dante trans-
mitter (output) and receiver (input) paths.
Simple Installation
The Model 5414 uses standard connectors
to allow fast and convenient interconnec-
tions. 3-conductor male and female XLR
connectors and 3-conductor ¼-inch jacks
are used to interface with the analog input,
analog output, and headphone output audio
signals. The unit connects to a local area
network (LAN) using a standard 100 Mb/s
twisted-pair Ethernet interface. The physical
interconnection is made by way of a Neu-
trik® etherCON RJ45 connector. While
compatible with standard RJ45 plugs and
patch cables, etherCON allows a rugge-
dized and locking interconnection method
that’s suitable for harsh or high-reliability
environments. Three LEDs on the back
panel display the status of the network
connection and Dante interface.
AC mains power can be connected directly
to the Model 5414 by way of a standard
3-pin detachable IEC C13 cord set; no
external power supply is used. Having
a “universal input,” the AC mains power
source can range from 100 to 240 volts,
50/60 Hz. A source of 10 to 18 volts DC can
also be connected to power the Model 5414.
This allows the unit to operate from a vari-
ety of battery and external DC power sup-
ply sources. The power input circuitry was
carefully designed to allow simultaneous
connection of both AC mains and DC power
sources. In this scenario the AC mains
source will power the Model 5414 while
only an extremely small amount of current
will be drawn from the DC source. Upon
loss of AC mains power the DC source will,
without interruption, begin to power the unit.
Far from a simple diode “OR” circuit, this is
a true “hot-swap” type design.
The light-weight aluminum enclosure
mounts in one space (1U) of a standard
19-inch rack enclosure. The rack-mounting
brackets (“ears”), located on the sides of
the Model 5414’s enclosure can be removed
to assistant in achieving special mounting
or installation requirements.
Future Capabilities and
Firmware Updating
The Model 5414 was designed so that
its capabilities can be enhanced in the
future. For example, at the time of the Model
5414’s initial release the ability to remotely
control operating parameters related to
the mic/line input channels is not offered.
But the unit’s internal architecture is such
that adding these capabilities in the future
should be possible.
A USB connector, located on the unit’s
back panel, allows the application firmware
(embedded software) to be updated using
a USB flash drive. Refer to Figure 2 for a
detailed view.

Page 10 Studio Technologies, Inc.
Model 5414
Mic/Line Input & Line Output
Dante Interface
To implement the Dante interface the Model
5414 uses Audinate’s Ultimo 4-in/4-out
integrated circuit. The firmware in this inte-
grated circuit can be updated via the unit’s
Ethernet connection, helping to ensure that
its capabilities remain up to date.
Installation
In this section the Model 5414 will be in-
stalled and signals interconnected. The
one-rack-space (1U) unit will be mounted
in an equipment rack. An Ethernet data con-
nection will be made using either a standard
RJ45 patch cable or an etherCON protected
RJ45 plug. Audio input and output connec-
tions will be made using 3-pin XLR con-
nectors and ¼-inch 3-conductor jacks. AC
mains power can be connected by means
of a detachable cord set that is compat-
ible with the unit’s 3-pin IEC 320 C14 inlet
connector. Some applications may warrant
connection of a source of 10 to 18 volts DC
which can be made by way of a 4-pin XLR
connector. The DC source can be used to
power the Model 5414 or it can serve as a
backup source for a connected AC mains
source.
System Components
The shipping carton contains a Model 5414
Mic/Line Input & Line Output Interface, user
guide, and AC mains cord suitable for use in
North America and Japan. When installation
will take place in other locations your dealer
or distributor should provide a suitable AC
mains cord.
Locating the Unit
The selected Model 5414 mounting loca-
tion will primarily depend on the unit being
within the 100-meter (325-foot) twisted pair
Ethernet cable limitation. But that can be
overcome by using a fiber-optic interconnec-
tion between the Model 5414-related Ether-
net switch and the other Ethernet switches
in the local-area-network (LAN). Also, as a
device that contains high-gain audio stages,
hum and noise pickup is possible by way of
the chassis and associated cabling. Locat-
ing the unit away from devices that radiate
strong AC fields is recommended.
Mounting
Once a mounting location has been select-
ed installation can begin. The Model 5414
requires one space (1.75 vertical inches
or 1U) in a standard 19-inch (48.3 cm)
equipment rack. Secure the unit into the
equipment rack using four mounting screws,
two per side.
Ethernet Connection
An Ethernet connection that supports
100BASE-TX (100 Mb/s over twisted-pair)
is required for the Model 5414’s Dante au-
dio-over-Ethernet connectivity. A 10BASE-T
connection is not sufficient for Model 5414
operation. A 1000BASE-T (“GigE”) connec-
tion is not supported unless it can automati-
cally “fall back” to 100BASE-TX operation.

Mic/Line Input & Line Output
Dante Interface
The 100BASE-TX Ethernet connection is
made by way of a Neutrik etherCON pro-
tected RJ45 connector that is located on
the back panel of the Model 5414. Refer to
Figure 3 for a detailed view. This allows con-
nection by way of a cable-mounted ether-
CON plug or a standard RJ45 plug. The
Model 5414’s Ethernet interface supports
auto MDI/MDI-X and, as such, eliminates
the need to use a crossover or “reversing”
cable.
makes changing input source cables easy
and minimizes the chance of damage to the
connectors on the Model 5414 or the mat-
ing connector should a cable be accidentally
grabbed, pulled, or snagged.
Prepare 3-pin male XLR mating connectors
such that pin 2 carries signal high (+), pin
3 carries signal low (–), and pin 1 is com-
mon/shield. It’s also highly probably that
unbalanced sources will interface correctly
with the mic/line inputs. With an unbalanced
source begin by connecting signal high (+)
to pin 2 and signal low/shield (–) to both
pins 1 and 3. If this provides a “clean” signal
interconnection then all is well. However, if
this results in hum or noise on the mic/line
input, try connecting signal high (+) to pin 2
and signal low/shield (–) only to pin 3; leave
pin 1 unconnected (“floating”).
Line Outputs
The Model 5414 provides four line outputs.
These analog outputs are designed for
general-purpose use which could include
connecting to analog inputs on devices such
as audio consoles, transmitters associated
with wireless in-ear monitors, matrix inter-
com systems, or amplified speakers. The
circuitry associated with the line outputs is
analog, capacitor-coupled, and has a source
impedance of 200 ohms. They will perform
optimally when driving loads of 2 k (2000)
ohms or greater. The signal level on the line
outputs will be +4 dBu when an associated
Dante receiver input level is –20 dBFS.
The line output circuitry is capable of a
maximum signal level of +24 dBu. This
20 dB of audio “headroom” means that
+24 dBu will be present a line output when
the corresponding Dante receiver input level
is 0 dBFS.

Mic/Line Inputs
The Model 5414 provides four inputs that
are intended for connection to microphone
or line-level analog audio signal sources.
It’s expected that in most applications the
connections to the mic/line inputs will be
on a temporary basis, varying “day-to-day”
as the applications change. As such,
permanent wiring to the four mic/line inputs
is not expected to be made. The 3-pin
female XLR connectors, located on the
Model 5414’s front panel, do not include
the traditional latches that would “lock” the
mating connectors to them. This was spe-
cifically implemented as a feature, allowing
mating connectors to automatically release
in the presence of significant force. This

Mic/Line Input & Line Output
Dante Interface
No special precautions are necessary when
using the line outputs in settings where
a variety of signals may be present. The
circuitry is protected from damage in cases
such as the accidental connection to a pow-
ered analog party-line (PL) intercom circuit
or to a microphone signal with P48 phantom
power present.
Four 3-pin male XLR connectors, located on
the Model 5414’s back panel, are provided
for interfacing the line outputs with associ-
ated equipment. Prepare 3-pin female XLR
mating connectors such that pin 3 is signal
high (+), pin 2 is signal low (–), and pin 1
is common/shield. To connect to an unbal-
anced load use pin 2 as signal high (+) and
pin 1 as low/shield; do not connect anything
to pin 3. Do not connect (short) pins 3 to
pins 1 on the mating connectors as this will
stress the output circuitry.
Headphone Output
The Model 5414 provides one 2-channel
(stereo) headphone output that is routed to
two jacks, one located on the front panel
and the other on the back panel. Refer to
Figure 4 for a detailed view of the back-
panel jack.
The audio sources for the headphone out-
put circuitry are selected using the Model
5414’s monitor section. A rotary control, also
located on the front panel, adjusts the level
of the 2-channel signal that’s sent to both
output jacks. The jacks are standard ¼-inch
3-conductor (stereo) tip-ring-sleeve type. As
would be expected, each headphone output
jack has the left channel on its tip lead, the
right channel on its ring lead, and common
for both channels on its sleeve lead.
The same signals are routed to both head-
phone output jacks but they function differ-
ently. The jack on the back panel will only
be active when nothing is plugged into the
jack on the front panel. This is provided as
an automatic disconnect function should the
headphone output jack on the back panel be
routed to inputs on an audio power amplifier
or powered speakers. In this way plugging a
pair of headphones into the jack on the front
panel will cause a break in the signal being
sent to the jack on the back panel. This will
result in connected speakers going silent,
effectively “muting” them.
To clarify what happens technically, when
a plug is inserted into the jack on the front
panel the tip and ring paths (the “normals”)
going from the front jack to the jack on the
back panel are disconnected (“lifted”). When
in this condition the tip and ring connections
on the back panel jack and anything con-
nected to them will “float” without a signal
path. They will not short to each other or to
the sleeve (common) connection.
As mentioned in the previous paragraph,
the headphone output is suitable not just for
connection to a pair of stereo headphones.
The audio quality is excellent and there’s
no reason why it can’t be used as an unbal-
anced line-level stereo output. It’s recom-
mended for applications of this type that
loads of 2 k ohms or greater be connected.
Prepare an interface cable such that the tip

lead of the mating 3-conductor ¼-inch phone
plug serves as signal high (+) for the left
channel, the ring lead of the plug serves as
the signal high (+) for the right channel, and
the sleeve lead of the plug serving as signal
low (–) for both the left and right channels.
Connecting AC and/or DC
Power
The Model 5414 requires a source of AC
mains or 10 to 18 volts DC for operation.
Either source can be connected with the
same result. Both can also be simultaneously
connected if a redundant (backup) power
scheme is desired.
Connecting AC Mains Power
The Model 5414 operates directly from AC
mains power of 100 to 240 volts, 50/60 Hz,
15 watts maximum. As a “universal mains
input” device, there are no switches to set or
jumpers to install. A 3-pin IEC 320 C14 inlet
connector on the back panel mates with a
detachable mains cord set. Refer to Figure 5
for a detailed view.
All units are supplied with an AC mains cord
that has a North-American (NEMA 5-15L)
standard plug on one end and an IEC 320
C13 connector on the other end. Units bound
for other destinations require that the appro-
priate cord set be obtained. The wire colors
in the mains cord should conform to the
internationally recognized color code and
be terminated accordingly:
Connection Wire Color
Neutral (N) Light Blue
Line (L) Brown
Earth/Ground (E) Green/Yellow
Because the Model 5414 does not contain
a power on/off switch it will begin operation
as soon as AC mains power is connected.
Safety Warning: The Model 5414 does
not contain an AC mains disconnect
switch. As such, the AC mains cord
plug serves as the disconnection device.
Safety considerations require that the
plug and associated inlet be easily
accessible to allow rapid disconnection
of AC mains power should it prove
necessary.
Connecting DC Power
The Model 5414 can also operate from a
source of 10 to 18 volts DC. The current
required from a 12 volt DC source is 1.1
ampere maximum. A 4-pin male XLR con-
nector, located on the unit’s back panel, is
used to connect the source of DC. Refer to
Figure 6 for a detailed view. Prepare a mat-
ing connector (female) so that pin 1 is – DC
and pin 4 is +DC. Pins 2 and 3 are not used
and should remain unconnected. This con-
nector type and pin-out are rapidly becom-
ing a broadcast DC power standard and
should be familiar to many technical person-
nel. Because the Model 5414 contains no
power on/off switch it will begin operation as
soon as a DC power source is connected.

As previously mentioned, both an AC mains
source and a DC source can be connected
at the same time. If this is the configuration
then the AC mains source will always power
the Model 5414 with the DC source serving
as a “hot standby.” Only if the AC source
fails will the unit draw power from the DC
source. This will occur automatically with no
interruption of Model 5414 operation. There
should be no problem with a battery being
connected as a standby power source. In
this “backup” mode there will be no continu-
ous current draw that will significantly dis-
charge it. This is because the Model 5414
draws less that 100 microamperes (uA) from
the DC input when an AC mains source is
connected.
Configuration
Analog-to-Digital Reference
Level
Three configuration choices allow the per-
formance of the mic/line input channels to
match common standards and practices.
By default, an analog signal with a level of
+4 dBu that’s connected to an input con-
figured for 0 dB gain will result in a digital
output signal (in the Dante domain) that has
a level of –20 dBFS. This will correspond to
an analog input signal with a level of +24 dBu
resulting in a digital output of 0 dBFS. This
implementation is compatible with that found
in SMPTE standards. A second configuration
choice allows the Model 5414 to be compat-
ible with EBU standards. This will result in
an analog input signal with a level of 0 dBu
to produce a Dante digital audio signal with
a level of –18 dBFS. A third configuration
choice allows an input signal with a level of
0 dBu to produce a digital signal with a level
of –20 dBFS. Refer to Figure 7 for details.

Digital-to-Analog Reference
Level
The relationship between the level of a
digital audio input signals and its associated
analog output level can be selected from
among three choices. By default the Model
5414’s line output channels have a level
of +24 dBu when the digital input level is
0 dBFS. This allows compatibility in
SMPTE®-compliant applications where
a digital audio signal with a nominal level

of –20 dBFS will translate to a signal in the
analog domain having a nominal level of
+4 dBu. The second choice is intended for
compatibility with EBU applications where
a digital input with a level of 0 dBFS should
result in an analog output level of +18 dBu.
A third setting configures the analog output
to be +20 dBu when the digital input is
0 dBFS. Refer to Figure 8 for details.

to-analog reference level settings
Dante Configuration
To integrate the Model 5414 into the desired
application several Dante-related parame-
ters must be configured. At a minimum, sub-
scriptions (routes) must be established with
the four Dante transmitter (output) channels
and to the four Dante receiver (input) chan-
nels. The Dante configuration settings will
be stored in non-volatile memory within the
Model 5414’s circuitry. As such, power-down
and power-up activities will not impact the
unit’s settings. The Model 5414 uses the
Ultimo 4-input/4-output integrated circuit to
implement the Dante architecture.
The four Dante transmitter channels associ-
ated with the Model 5414’s Dante interface
must be assigned to the desired Dante
receiver channels on other devices. The
Model 5414’s four receiver channels must
be assigned to the desired transmitter chan-
nels on associated Dante devices. This will
typically be done with the Dante Controller
software application which is available for
download free of charge at www.audinate.
com. Versions are available to support
Windows® and OS X® operating systems.
The Model 5414 is compatible with the Dante
Domain Manager (DDM) software applica-
tion. It can also be configured for AES67 op-
eration. This requires a setting to be enabled
within the Device Info section of the Dante
Controller application.
Within Dante Controller a “subscription” is
the term used for routing a transmitter flow
(a group of output channels) to a receiver
flow (a group of input channels). The Ultimo
integrated circuit used in the Model 5414
limits the number of Dante flows to four
— two transmitter and two receiver. Each
can be independently selected for unicast or
multicast. (Note that in the AES67 mode the
four transmitter (output) channels will func-
tion in multicast; unicast is not supported.)
If the Model 5414’s transmitter channels
need to be routed to more than two flows
it’s possible that an intermediary device with
enhanced flow capability, such as the Studio
Technologies’ Model 5422 Dante Intercom
Audio Engine, can be used to “repeat” the
signals. (Use the Model 5422’s pass-thru
group configuration mode to provide this
resource.)
The Model 5414 supports an audio sampling
rate of 48 kHz along with no pull-up/pull-
down values. The Model 5414 can serve as
the clock master for a Dante network but in
most cases that would not be optimal.

Model 5414
Mic/Line Input & Line Output
Dante Interface
The Model 5414 has a default Dante device
name of ST-M5414 followed by a unique
suffix. The suffix identifies the specific Model
5414 that is being configured. The suffix’s
actual alpha and numeric characters relate
to the MAC address of the Ultimo integrated
circuit that’s present in the specific Model
5414. The four Dante transmitter (output)
channels have the default names of Ch1,
Ch2, Ch3, and Ch4. The four Dante re-
ceiver (input) channels have default names
of Ch1, Ch2, Ch3, and Ch4. Using Dante
Controller these names can be revised as
appropriate for the specific application.
Operation
At this point the Model 5414 should have its
Ethernet, mic/line input, line output, head-
phone output, and AC mains connections
implemented as desired for the application.
The desired input and output level configu-
ration should be made using the switches
on the back panel. The four Dante trans-
mitter (output) channels and four Dante
receiver (input) channels should have been
routed using the Dante Controller software
application. Normal operation of the Model
5414 can now begin. The unit is designed
for continuous operation with no regular
maintenance required.
Initial Operation
The Model 5414 will begin its power-up
process as soon as AC mains power is con-
nected. As an integrity check all the meter
LEDs, status LEDs, and 2-digit LED display
digits located on the front panel will light in a
test sequence. This will take approximately
five seconds and will be followed by the
application firmware’s (embedded software)
version number being displayed on the
2-digit LED display for about one second.
At this point preliminary operation will begin.
Full Model 5414 operation will depend on
the establishment of Dante connectivity by
way of the Ethernet connection.
Upon power down all of the Model 5414’s
operating parameters are saved in non-
volatile memory. In this way all settings, such
as mic/line preamplifier gain and P48 on/off
status, will be restored upon the next power-
up cycle.
Also upon Model 5414 power up the status
LEDs on the back panel will light in various
manners. The status LED located below the
USB connector will flash once to indicate that
it is functioning. The two Dante and one net-
work status LEDs, located below the ether-
CON RJ45 connector on the back panel, will
light in seemingly random ways as Ethernet
and Dante network performance begins.
Please refer to the next section of this guide
for details on what these LEDs indicate.
Note that during the first few seconds after
the unit powers-up a few mechanical clicks
may be heard emanating from within the
Model 5414’s enclosure. This is normal and
is a function of the mic/line input attenuator
circuitry’s latching relays being set to their
correct status.
User Displays and Controls
The user is now presented on the front panel
with eight LED level meters, twenty status
LEDs, and ten pushbutton switches; on the
back panel are four status LEDs. These
resources are simple to understand and use
and should prove to be useful in obtaining
the desired performance.

Ethernet and Dante Status
LEDs
As previously mentioned, three status LEDs
are located below the etherCON RJ45 con-
nector on the Model 5414’s back panel.
The LINK/ACT LED will light green whenever
an active data connection to a 100 Mb/s Eth-
ernet network has been established. It will
flash on and off in response to data packet
activity. The SYS and SYNC LEDs display
the operating status of the Dante interface
and associated audio-over-Ethernet network.
The SYS LED will light red upon Model 5414
power up to indicate that the Dante inter-
face is not ready. After a short interval it will
light green to indicate that it is ready to pass
audio data with another Dante device. (It
doesn’t indicate that data is passing but sim-
ply that data could be passing!) The SYNC
LED will light red when the Model 5414 is
not synchronized with a Dante network. It
will light solid green when the Model 5414
is synchronized with a Dante network and
an external clock source (timing reference)
is being received. It will slowly flash green
if this specific Model 5414 is serving as the
clock master for the Dante network. (It’s not
expected that a Model 5414 will serve as a
clock master but technically it is capable of
doing that.)
How to Identify a Specific
Model 5414
The Dante Controller software application
offers an identify command that can be used
to help locate a specific Model 5414. When
identify is selected for a specific unit that
unit’s six audio level meters will light in a
unique pattern. This aggressive display will
make the unit readily identifiable. In addition,
the SYS and SYNC LEDs, located directly
below the etherCON connector on the back
panel, will slowly flash green. After a few
seconds the LED identification patterns will
cease and normal Model 5414 level meter
and Dante status LED operation will again
take place. Audio performance will not be
impacted by the use of the identify com-
mand. As such it’s perfectly acceptable to
use the identify command any time it would
be useful.
Mic/Line Inputs
The Model 5414’s four mic/line inputs are
intended for connection to virtually any
microphone or line-level source. The input
circuitry is electronically balanced (differen-
tial), capacitor coupled, and protected from
damage should a moderate DC voltage
be accidentally connected. For example,
no damage will occur if a powered analog
party-line (PL) intercom circuit be acciden-
tally connected. (A PL circuit would typically
have approximately 30 volts DC present.)
The 3-pin female XLR connectors used for
the mic/line inputs were specifically located
on the front panel so that they can be read-
ily accessed. Refer to Figure 9 for details.
This makes changing sources and associ-
ated cabling fast and simple. Allowing “on
the fly” set up and use was a main goal. The
XLR connectors are “latch-less” and rely
on friction instead of a mechanical lock to
provide a positive retention force.
Each of the four mic/line input channels can
be individually configured for preamplifier
gain, P48 phantom power, and high-pass
filter (HPF). This can be done locally using a
common set of pushbutton switches. Refer
to Figure 10. Alternately, the STcontroller
software application can be used to view
and change the gain of the preamplifier, P48
phantom power on/off status, and high-pass
filter (HPF) on/off status.

Model 5414
Mic/Line Input & Line Output
Dante Interface
An 8-segment LED meter is associated
with each of the four mic/line inputs. These
provide a real-time view of the signals as
they are presented in the digital domain
to the four Dante transmitter (output) chan-
nels. The meters display in dBFS which
is the number of dB relative to the maxi-
mum level; digital maximum (full scale) is
0 dBFS. Associated with each input channel
is an orange LED that displays the on or off
status of the P48 function and a green LED
that displays the on or off status of the HPF
function.
The Model 5414 provides a common set of
resources to display and select preamplifier
gain as well as selecting the on/off status of
the P48 and HPF functions. The common
resources consist of a 2-digit LED display
to indicate the selected preamplifier gain,
two pushbutton switches to raise or lower
the preamplifier gain, a pushbutton switch
to select the on or off status of the P48
phantom power, and a pushbutton switch
to select the on or off status of the HPF.
Channel Select Button
Each mic/line input channel has a push-
button switch, labeled SEL, that’s used for
“assigning” the common resources to that
specific input channel. Simply tap (momen-
tarily press) a channel’s select button and
the common resources are assigned to that
channel. A blue LED, located on the front
panel directly below each channel select
switch, will light to show which mic/line input
channel is linked to the common resources.
As expected, only one blue SEL LED can be
lit at any one time.
The mic/line input select buttons are also
used to activate a monitor input channel
select function. If a select button is pressed
and held for two seconds the monitor sec-
tion will automatically select that channel as
a monitor source. If the monitor section is
in the single-channel mode then the mic/
line input channel whose select button is
pressed and held will have its audio signal
as the only monitor source. If the monitor
section is in the dual-channel mode then the

mic/line input channel whose select button
is pressed and held will have its audio signal
become one of two audio sources that are
selected. This “hidden” feature can be very
useful when configuring a mic/line input
channel and a quick check of the associated
audio signal is desired.
Preamplifier Gain
As soon as the common resources have
been linked to an input channel the 2-digit
LED display will indicate that input’s pre-
amplifier gain setting. Use the up and down
buttons in the common resources to in-
crease or decrease the preamplifier gain to
the desired setting. Simultaneously pressing
both the up and down buttons will immedi-
ately change the preamplifier gain to 0 dB.
This is another “hidden” feature that allows
an input to be rapidly returned to a known
preamplifier gain setting. There are 20 pre-
amplifier gain choices that range from 0 dB
to 70 dB: 0 dB (line), 10 dB, and 19 through
70 dB in 3-dB steps. When changing from
the 0 dB to the 10 dB setting, or vice-versa,
a user may observe a slight mechanical
click coming from inside the Model 5414’s
enclosure. This is normal, a result of a state
change being made to an electromechani-
cal relay that is used by an input attenua-
tor (“pad”) associated with the preamplifier
circuitry.
The 0 dB preamplifier gain setting is appro-
priate when a source with a nominal level in
the range of 0 to +4 dBu has been connect-
ed. The 10 dB preamplifier gain setting might
be correct when a “semi-pro” signal source,
such as from a personal audio device. e.g.,
tablet computer or portable phone, has been
connected. It would be typical for a handheld
or headset-associated dynamic microphone
that is used in a close-talk environment to
need 40 or 43 dB of gain. As a general rule,
one should set a channel’s preamplifier gain
such that the green LEDs on its associated
level meter will light whenever a signal is ac-
tive while its yellow LEDs should rarely light
and its red LED should never light.
The relationship of an analog input signal at
a specific level to its corresponding digital
audio output is dependent on Model 5414’s
input configuration. Three choices are avail-
able and made using switches on the unit’s

back panel. All choices are referenced to
the mic/line input channels being set for
0 dB of gain. The default choice is for an
input of +4 dBu to result in a digital output
level of –20 dBFS. This is appropriate for
SMPTE-compliant applications. The second
configuration choice provides a –20 dBFS
digital signal level when the analog input sig-
nal has a level of 0 dB. This meets the needs
of some common industry practices. The
third choice matches the requirements of
EBU-compliant applications. In this case an
analog input signal with a level of 0 dBu will
result in a digital signal level of –18 dBFS.
P48 Phantom Power
To locally change the on or off status (“tog-
gle”) the P48 phantom power function re-
quires simply tapping the P48 button. The
selected mic/line input channel’s orange LED
will reflect the revised on or off condition. By
design, if P48 has been enabled it will apply
no matter what preamplifier gain has been
selected. This includes the 0 dB and 10 dB
gain settings which are not normally associ-
ated with microphone sources.
High-Pass Filter (HPF)
To locally change the on or off status of the
HPF function tap the HPF button. This will
“toggle” the status between on and off or
vice-versa. The selected mic/line input chan-
nel’s green LED will change state to reflect
the HPF function’s current on or off status.
The status of the HPF filter function is not
impacted by the P48 phantom power status
and selected preamplifier gain. To under-
stand exactly how the HPF function impacts
a mic/line input signal refer to the Specifica-
tions section of this guide.
Remote Configuration of Gain,
P48, and HPF
Using the STcontroller application allows
personal computer users to view and adjust
the Model 5414’s preamplifier gain, P48
phantom power on/off status, and high-pass
filter (HPF) on/off status. The application is
available for download on the Studio Tech-
nologies’ website (www.studio-tech.com).
Its initial release is compatible with the Win-
dows® operating system. Changes made
using the application will be displayed in
real-time on the Model 5414’s 2-digit display.
Changes made to the preamplifier gain, P48
phantom power on/off status, and HPF on/off
status using the Model 5414’s local pushbut-
ton switches will be displayed in STcontroller.
Line Outputs
On the Model 5414’s back panel are four
3-pin male XLR connectors that provide ac-
cess to the line outputs. Refer to Figure 11
for a detailed view. For these analog line-
level outputs to be active only requires using
the Dante Controller software application to
establish the subscriptions (routes) that link
the desired Dante audio sources (transmit-
ters) with the Model 5414’s Dante receiver
(input) channels. The relationship between
the digital input level and the analog output
level will depend on the unit’s configura-
tion. This is achieved using the configuration
switches on the unit’s back panel. The de-
fault configuration would have a digital level
of –20 dBFS on an input channel result
in an analog output of +4 dBu. And when
digital level reaches its 0 dBFS maximum
the output level will be +24 dBu. This is com-
patible with SMPTE applications. An alter-
nate configuration choice allows the analog
output level to be 0 dBu when a digital input
has a level of –20 dBFS. In this case the
