GLOSSARY
The following are a few words that may serve you
well while reading this manual. These aren’t in depth
explanations, but should hopefully give you the basics
and a place to start.
Balanced Connections – balanced connections o󰀨er
three conductors, carrying a ground, an in-phase signal,
and an out-of-phase signal. Once the two signals are sent
from one device to another, the out-of-phase signal has
its phase inverted and the two signals are combined. Any
interference picked up along the way is removed through
to phase cancellation. This allows cables to be run over
long distances without collecting excessive noise on the
way.
Compressor – a Compressor reduces signals over a
user-dened threshold by a user-dened amount/ratio.
Dynamic Processor – is any kind of processor that
dynamically – or in real time – adjusts signal properties.
EQ – Equalizer – is a device or process that allows users
to boost or attenuate audio signals at specic frequencies.
Euroblock – These types of inputs allow for self-wiring
of connections for permanent installations. Check the
“Getting Started” section for more information on wiring.
GEQ – Graphic Equalizer – is in essence the same as
an equalizer, but this title is reserved for equalizers with
more ‘bands’ than the typical EQ. While a typical channel
EQ may only allow for 3 or 4 frequencies to be adjusted,
a graphic equalizer may allow for 31 di󰀨erent frequencies.
GUI – Graphical User Interface – this is the remote PC
software used for the DMP1616.
HPF – High Pass Filter – a high pass lter will cut or
signicantly reduce all audio signals below a particular
user-dened frequency, allowing – as the name suggests
– high frequency sounds to pass through.
High Shelf Filter – the high shelf lter will reduce or
increase all audio signals below a particular frequency.
The level at which the signal is boosted/attenuated is
determined by the user.
Limiter – work just as compressors do; however with an
input to output signal ratio permanently set to innity-to-1.
LPF – Low Pass Filter – a low pass lter will cut all
audio signals above a particular user-dened frequency,
allowing low frequency sounds to pass through. This is
signicantly useful when using subwoofer speakers on
particular outputs.
Low Shelf Filter – the low shelf reduces or increases
the level of audio signals below a particular frequency
selected by the user. The level at which the signal is
altered is also set by the user.
Network – a network is a series or group of computers that
are interconnected so as to share information. In the case
of the DMP1616, the network allows for remote operation
of the device using our Windows-based computer.
Noise Gate – a noise gate is a dynamic process that
turns o󰀨 or signicantly attenuates the audio signal
passing through it when the signal level falls below a user
adjustable threshold.
Unbalanced Connections – unlike balanced connections,
unbalanced connections only have 2 conductors: one for
the signal and one for the grounding. This, unfortunately,
makes them more susceptible to noise and interference.
GETTING STARTED
For easy control of the DMP1616, you will need to connect the device to a network-enabled Windows computer. By
installing the Asystems software on a computer will allow for remote control of this unit. Enter the DMP1616’s IP address
into the PC software to locate the DMP1616 on either the local area network.
Connect all necessary input and output devices. Input can be achieved through correctly wired euroblock connectors.
Wiring for balanced euroblock connectors should be as follows:
Pin 1: Shield/Ground
Pin 2: Cold (–)
Pin 3: Hot (+)
Whereas unbalanced connectors can be wired as so:
Pin 1: Shield/Ground
Pin 2: Link to Pin 1
Pin 3: Hot (+)

The Dante expansion card should come pre-installed with
the DMP1616D (and is not included with the DMP1616).
This is an optional component that is not included on all
versions of the DMP1616.
The “Primary” port on the Dante card can be connected to
your network router. The Secondary port can be connected
to the Primary port of additional units. Alternatively, all
units can be connected to the router using their “Primary”
ports.
The Audinate Dante Controller can be downloaded
through their website (www.audinate.com). This is used to
route the network signals from numerous Dante-enabled
devices. Each device will show up as its own independent
signal with input and output channels listed. All units will
be automatically discovered by the software.
Signals can be routed internally using the instructions
found in section 5. The actual network input signals
received by your DMP1616s are determined by the
aforementioned Dante Controller software. It should be
noted that each Network input mix can only have a single
source assigned to it.
Connecting additional units to your network will
automatically be recognized by the software, allowing any
of these systems to have their signals routed throughout
the network.
In addition to the regular network routing of signals, the
Dante expansion cards are compatible with Audinate’s
DANTE CONNECTIVITY (DMP1616D ONLY)

GENERAL SETTINGS
FIRMWARE UPDATE
When performing a rmware update, a few steps need to
be followed. First of all, set the rst pole of the DIP switch
to the upper-most position.
A connection needs to be established between the
DMP1616 system and the Windows remote software.
After this is done, open the “Flash Programmer” pull-down
menu at the top of the Audio Device Workshop software.
Select “Launch Flash Programmer” from the menu. Here
you can select the DMP1616 rmware (found on the
Asystems webpage) and begin the rmware update. Do
not turn the computer or DMP1616 o󰀨 until the rmware
update process has completed.
HOW TO SET THE SYSTEM IP ADDRESS
Connecting the DMP1616 to a computer for remote operation requires the user to enter an IP address for the unit. There are
two controls that help determined the IP address of the DMP1616 matrix processor. The rst is the UNIT ID rotary control,
that lets you select 0 – 9 and A – F. The second is the DIP switch located directly beside the rotary switch. The 3rd and 4th
poles of the DIP switch can be used to set a numerical value between 0 and 3. These combine with the UNIT ID rotary switch
to form a hexadecimal value for the last value of the IP address (as indicated below).
The congurable range for the last digit is 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E and F.

Hexadecimal to Decimal Conversion
The unit ID conguration mechanism of DMP1616 is developed based on “hexadecimal numeral system”. Therefore, a
scientic calculator may be required when setting the unit ID of the IP address for DMP1616. Below is the procedure for
setting the unit ID:
1. Dene the IP address for your DMP1616.
2. Convert the decimal value of the host bits of the IP address to a Hexadecimal value (consult the provided table).
3. Set PINS 3 and 4 on the 8-PIN DIP switch according to the rst digit of the converted Hexadecimal value.
4. Set the rotary switch according to the second digit of the converted Hexadecimal value.
Example: To set an IP address of “192.168.0.21” on your DMP1616, the rotary control should be set to 5 and the DIP
switches 3 and 4 should be set to ON and OFF, respectively. This sets a hexadecimal value of 15, which - converted to
decimal - is 21. Consult the included chart for hexadecimal to decimal conversion.

Meters
The DMP1616 has three full pages of Meters, including
“Meters”, “Meters/Dynamics” and “Meters/AutoLeveler.”
These give real-time details on the input and output
signals being sent to and from the DMP1616, as well as
o󰀨ering gain reduction details on compressor and limiters.
Logic I/O
The general purpose interface output is used to remotely
control the DMP1616. When properly setup, you can
recall presets and/or remotely adjust other properties of
the device.
GPIO In
The GPIO In eld is for use with the Asystems RM-4
remote preset control. Up to two can be used at any
one time (ports 1 to 8). In essence, users can save any
number of “scenes” to the device, and use the RM-4 to
instantly recall the scene. This is done by saving the
scene through the “Preset Options” pull-down menu at
the top of the screen.
Presets will correspond to a particular number, and this
GPIO In menu can be used to assign the preset number
to a “port” for use with the RM-4. For information on
wiring the RM-4 control to a particular port, check the
appropriate page within this menu.
A name or “Subject” can be assigned to each scene.

Analog In
The Analog In submenu in the Global Settings menu
o󰀨ers two simple functions. These are:
Phantom Power: When using any input with condenser
microphones, +48V DC of phantom power can be
activated right here. Do not activate phantom power
unless necessary.
HPF: Users are able to activate a high pass lter through
this option, essentially removing low-frequency noise.
This is great for use in conjunction with microphones,
where low-frequency noise and stage rumble can be
removed.
Compressor/Limiter
This menu allows compressors and limiters to be applied
to the channel output
Limiter Threshold: This control determines the threshold
for the limiter function. This means that no signal will
surpass the selected threshold, being ‘compressed’ at a
ratio of innity:1.
Compressor Threshold: Use this control to set the
threshold of the compressor function. Any signals that
surpass the selected threshold will be compressed at the
selected ratio.
Compressor Ratio: This control can be used to set
the ratio for the compressor. The ratio is expressed as
<input>:<output>.
Compressor Attack: This control adjusts the attack time
of the compressor, essentially determining the time taken
for the compressor to kick in after it passes the selected
threshold.
Compressor Release: The release control determines the time the DMP1616 will wait before disengaging the compressor
when the signal bypasses the selected threshold.
Side Chain HPF: This allows users to set a high pass lter on these channels to essentially help rid these channels of
low-frequency noise.
System
System Clock: This menu allows you to select the
internal sampling rate of the DMP1616. Users are able
to select between either 44.1 or 48 kHz. You can also
choose to take clock settings from the audio networking
feature. The ENTER button must be pushed to conrm.
DSP Usage: view DSP usage here (or on the DSP page).
Power Settings: There are three power settings on the
DMP1616. The software power can be turned on and o󰀨,
essentially enabling the DMP1616 to be turned on and
o󰀨 via the software – including event scheduling. The
hardware power can be selected on and o󰀨, essentially
allow the unit to be activated and deactivated using the
hardwired switch on the front of the DMP1616.

RM-4 Preset Recall Remote
With a single RM-4 you will be able to recall up to 4
independent presets. The DMP1616 can use up to two
RM-4 remotes.
Wiring
The RM-4 can be wired to the “Preset” section on the
rear of the DMP1616.
As shown, there are 8 pins for each of the 4 preset buttons
on the RM-4, as well as grounding pins to the left. Each
of the 8 pins corresponds with a user-selected “Scene”
within the control software. The DMP1616 allows for up
to 2 RM-4 preset recall controllers to be connected.
Suggested wiring:
Setup And Operation
To utilize the RM-4, you simply need to assign a preset
to each of the buttons. This is done within the Control
Software of the DMP 1616. First, enter the “Global
Settings” menu and find the GPIO submenu. Here you
will find the “Preset” panel (shown below). Each of the
pins on the rear of the device will correspond to the Ports
listed here. You can then select which “Scene” (or preset)
you wish to assign to that port.
The pre-saved scenes are all listed within the Utility
menu. Scenes can be saved (and recalled) in this
menu. The “No” in the Preset window on the GPIO
page will correspond with the ‘Scene’ numbers found
here. The Subject in the Preset window will be updated
automatically.
A single preset can be recalled at any one time. The
button selected on the RM-4 will lock down, releasing
any other preset button that may have previously been
selected.

Below you will nd the onboard signal processors of the
DMP1616 and information on their use and respective
parameter. These can be applied to any of the 8 input or
8 output channels of the DMP1616.
Compressor-Limiter
Compressor Threshold: Use this control to set the
threshold of the compressor function. Any signals that
surpass the selected threshold will be compressed at the
selected ratio.
Compressor Attack: This control adjusts the attack
time of the compressor, essentially determining the time
taken for the compressor to kick in after it passes the
selected threshold.
Ratio: This control can be used to set the ratio for the
compressor. The ratio is expressed as <input>:<output>.
Compressor Release: The release control determines
the time the DMP1616 will wait before disengaging the
compressor when the signal bypasses the selected
threshold.
Limiter Threshold: This control determines the threshold
for the limiter function. This means that no signal will
surpass the selected threshold, being ‘compressed’ at a
ratio of innity:1.
Output Gain: This control determines the amount of
gain applied to the signal after already passing through
the compressor-limiter.
On & Reset Buttons: The on button is, of course, used
to turn the Compressor-Limiter on and o󰀨, while the reset
button will reset all values to default.
Gate
On: This button turns the gate on and o󰀨.
Reset: Push the reset button to restore all parameters
back to default.
Dynamic Graph: This graph shows the currently set
gate properties and how it will a󰀨ect your audio.
Level Meters: These meters give the input and output
level of the gate for the current channel.
Gain Reduction: The gain reduction meter will provide
a real-time indication of any reduction in signal caused
by the gate.
Threshold: This control will set the threshold of the gate
function. Any signals that fall below the set threshold will
activate the gate function.
Range: This control sets the amount of attenuation when
the gate is closed.
Attack: This control adjusts the attack time of the gate.
This is the time the DMP1616 will wait after the signal
drops below the threshold before engaging the gate.
Hold: The hold will allow you to select the length of time
the gate will remain open after the signal drops below the
set threshold.
Release: The release control determines how long the
gate will wait before disengaging when the signal rises
back above the selected threshold.
SIGNAL PROCESSORS
Expander
On: This button turns the expander on and o󰀨.
Reset: Push the reset button to restore all parameters
back to default.
Dynamic Graph: This graph shows the currently set
expander properties and how it will a󰀨ect your audio.
Level Meters: These meters give the input and output
level of the expander for the current channel.
Gain Reduction: The gain reduction meter will provide
a real-time indication of any reduction in signal caused
by the expander.
Threshold: This control will set the threshold of the
expander function. Any signals that fall below the set
threshold will activate the expander at the user-set ratio.
Ratio: This signal sets the ratio of the expander function.
When a signal drops below the threshold, the signal will
be decreased by the selected ratio.
Attack: This control adjusts the attack time of the gate.
This is the time the DMP1616 will wait after the signal
drops below the threshold before engaging the gate.
Release: The release control determines how long the
gate will wait before disengaging when the signal rises
back above the selected threshold.
Delay
Adding a delay on output can be particularly helpful to
help time align drivers within a single cabinet or help avoid
delay in larger multi speaker setups. For example, when
there are a number of drivers in a single cabinet, typically
they’re di󰀨erent distances from the front of the cabinet.
The tweeter, typically longer than the woofer, could have
its driver 8 inches deeper than the woofer. The problem
this creates is the sound from the woofer will be pushed
out a fraction of a second before the tweeter, arriving at
the wavefront at di󰀨erent times. Adding a 0.6 millisecond
delay to the woofer can combat this, essentially making
the signal wait for the tweeter to catch up.
Delay: Use this control to adjust the delay time. To the
right of the control, the selected delay will be indicated in
milliseconds, meters and feet.
Temperature Control: This allows you to set the
current temperature for the delay circuit. This allows the
DMP1616 to better rene the delay’s ‘meter’ and ‘feet’
results. The temperature is indicated in both degrees
Celsius and degrees Fahrenheit.
On & Reset Buttons: The on button is used to turn the
delay circuit on and o󰀨. The reset button resets all values
to default.
Signal Generator
Type: Select from Pink Noise, White Noise, Sine or
sweep waves.
Frequency: Adjust the frequency of the sine wave
between 20Hz and 20KHz, as required.
