Component Rack System Quick Guide 2
2:1.Welcome
Congratulations on buying a Coastal Source amplifier!
We know you are eager to use your new CRS amplifier,
but please take a moment to read this quick guide and the
safety instructions. In case you have any questions, please
do not hesitate to contact your dealer or Coastal Source.
The CRS amplifier is specifically designed for installation
applications. In just 1 RU, the CRS offers smaller dimensions,
lighter weight and the traditionally amazing sound quality
and reliability of all Coastal Source products.
CRS amplifiers implement a high efficiency
microprocessor controlled power supply with built in PFC
(Power Factor Correction) that allows flawless worldwide
operation with any AC mains voltage in the range 85-275 VAC
tolerant to peak up to 400 V. The patented SRM (Smart Rails
Management) technology allows to maximize the efficiency
of the system and drastically reduce power consumption at
any load and usage condition.
A secondary high efficient power supply is present to
keep the system responsive at any operating condition, so
that system check and monitoring can be performed even
in stand-by and deep-sleep modes.
CRS is designed to work with lo-Z (from 2Ω) and with
70V/100V distributed lines: any mixed configuration of low
and high impedance output loads can be realized, making
the CRS suitable to all applications in installed sound
reinforcement system.
The CRS amplifiers extend system performance with
the support to Dante™ digital audio networking architecture
and the on board high-end signal processing.

Installation 3
3:1.Location
CRS amplifiers are meant to be installed into rack cabinets.
In order to limit the risk of mechanical damages, the amplifiers
must be secured to the rack using both frontal and rear mounting
brackets. We recommend to use eight M6 or 12-24 UNC-2B
screws for threaded holes or cage nuts.
The AC mains connector of the units must be connected
to a proper circuit breaker.
Install this amplifier as far as possible from radio tuners
and TV sets. An amplifier installed in close proximity of such
equipment may experience noise or generic performance
degradation. Placing and using the amplifier for long periods
of time on heat generating sources will affect its performance.
Avoid placing the amplifier on heat generating sources.
NOTE: CRS Amplifiers may be mounted vertically
as long as there is at least 20” between the air
intake/outlet and surrounding surfaces.
3:2.Cooling
Install the amplifier in a well-ventilated location: the
ventilation openings must not be impeded by any item such
as newspapers, tablecloths, curtains, etc; keep a distance
of at least 20 in from the front and rear ventilation openings
of the amplifier.
All Coastal Source amplifiers implement a forced-air
cooling system to maintain low and constant operating
temperatures. Drawn by the internal fans, air enters from
the front panel and is forced over all components, exiting at
the back of the amplifier.
The amplifier’s cooling system features “intelligent”
variable-speed DC fans which are controlled by the heat sink
temperature sensing circuits: the fans speed will increase
only when the temperature detected by the sensors rises
over carefully predetermined values. This ensures that fan
noise and internal dust accumulation are kept to a minimum.
Should however the amplifier be subject to an extreme
thermal load, the fans will force a very large volume of air
through the heat sink. In the extremely rare event that the
amplifier should dangerously overheat, sensing circuits
shut down all channels until the amplifier cools down to a
safe operating temperature. Normal operation is resumed
automatically without the need for user intervention.
CRS amplifiers can be stacked one on top of the other
due to the efficient cooling system they are equipped with.
There is however a safety limit to be observed: in case
a rack with closed back panels is used, leave one rack unit
empty every four CRS amplifiers to guarantee adequate air
flow (see Panel T, p. 9).
3:3.Cleaning
Always use a dry cloth for cleaning the chassis and the
front panel. Air filter cleaning should be scheduled according
to the dust levels in the amplifier’s operating environment.
Disconnect the AC mains source before
attempting to clean any part of the amplifier
In order to clean the vent filters you need to remove the
front cover: never attempt to open any other part of the unit.
1. Firmly grip the outermost blue panel and pull it outwards
(see Panel B, p. 4).
2. When the front panel is removed, the air filter (looking
like a shiny black plastic sponge) will be exposed.
You may use compressed air to remove the dust from
filters, or wash it with clean water: in the latter case ensure
that the filter is dry prior to reassembly.
3:4.Precautions regarding installation
WARNING: TO PREVENT FIRE OR ELECTRIC SHOCK
f This device must be powered exclusively by earth
connected mains sockets in electrical networks
compliant to the IEC 364 or similar rules.
f Install the unit into a rack cabinet.
f A sectioning breaker between the mains connections
and the amplifier should be installed inside the rack
cabinet.
f Properly fit the AC mains plug to the amplifier inlet.
f Before powering this amplifier, verify that the correct
voltage rating is being used.
f Verify that your mains connection is capable of
satisfying the power ratings of the device.
f Do not use this amplifier if the electrical power cord is
frayed or broken.
f Output terminals are hazardous: wiring connection to
these terminals require installation by an instructed
person and the use of ready-made leads.
f Take care to lock the output terminal before switching
the device on.
f To avoid electrical shock, do not touch any exposed
speaker wiring while the amplifier is operating.
f Do not spill water or other liquids into or on the amplifier.
f No naked flame sources such as lighted candles
should be placed on the amplifier.
f Do not remove the cover. Failing to do so will expose
you to potentially dangerous voltage.
f The manufacturer cannot be held responsible for
damages caused to persons, things or data due to an
improper or missing ground connection.
f Contact your dealer or Coastal Source for ordinary
and extraordinary maintenance.
It is absolutely necessary to verify these fundamental
requirement of safety and, in case of doubt, require
an accurate check by qualified personnel.
12 | Component Rack System
This device must be powered exclusively by
earth connected mains sockets in electrical
networks compliant to the IEC 364 or similar rules.
Coastal Source recommends plugging the
CRS Amplifier into a 20A rated breaker.
AC mains connections must be performed
only by professional or qualified personnel
according to local electrical authorities guidelines.
3:5.AC mains supply
CRS amplifiers implement a universal switching mode
power supply with power factor correction operating in the
range from 100 VAC up to 240 VAC ±10%.
AC mains connection is in the rear panel through the IEC
C20 inlet: the approved power cord is provided (see Panel
N, p. 7).3:6.Switch ON/OFF
Once properly powered (power cord inserted, sectioning
breaker closed), the system can be either ON or in STANDBY
mode depending on its state at last power off.
In order to toggle between ON and STANDBY press and
hold the power button for 3 seconds (see Panel C, p. 5).
Please consider that the operating condition can be modified
by the REMOTE ON and REMOTE OFF configuration (see
§3:9.Remote ON/OFF (standby mode).
3:7.Energy Save
The Smart Rails Management technology implemented
in the power supply unit allows it to reduce the power
consumption when the input signal falls under a defined
threshold.
Signal activity is monitored on the input section of the
amplifier so that the system can resume normal operation
in a matter of milliseconds when an incoming signal is
detected on the channels. Once switched on, Energy Save
is active on each channel independently.
If the signal is missing for more than 30 minutes on all
channels, the auto standby is applied and the main PSU
is turned off to further save energy*. Normal operation is
resumed in a matter of milliseconds when an incoming
signal is detected on the channels.
In order to activate the Energy Save feature, locate the
NRG SAVE switch on the rear panel (see Panel D, p. 5)and
set it ON (high).
TAB. 1 shows the power consumption in idle mode when
the Energy save is either enabled or disabled.

3:8.Breaker save
In case the power grid is unable to provide enough
current to continuously drive the loads, or when the number
of attached amplifier to the same AC mains is such that one
can reach the critical power absorption from the line, it is
possible to activate the Breaker Save feature.
When activated, the Breaker Save feature reduces
(halves) the maximum continuous current absorption from
the mains. This slightly reflects on the overall performance
of the system reducing the available output power.
In order to activate the Breaker Save feature, locate the
BRK SAVE switch on the rear panel (see Panel D, p. 5)and
set it ON (high).
3:9.Remote ON/OFF (standby mode)
Remote ON/OFF is available through the dedicated
terminals on the rear panel (see Panel D, p. 5).
Both terminals respond to the differential voltage
between the contacts: a voltage difference in the range
5 VDC - 24 VDC triggers the control. Any voltage exceeding
28 VDC may damage the input circuitry.
The couple of terminals act depending on the actual
state of the amplifier, as shown in .
REMOTE ON REMOTE OFF AMPLIFIER STATE
Vdiff ≥5V Any Force Turn ON
Vdiff < 3V Vdiff ≥5V Force Turn OFF
Vdiff < 3V Vdiff < 3V
No Change
(Keep either standby
or in current state)
In order to remotely toggle between standard operating
and standby modes, the AC mains power must be
connected.
*Time out time is selectable via Armonìa in DSP+D Versions
FIG. 1:Press and hold the power button for 3
seconds to toggle between ON and STANDBY.
CRS | 13
Connections 4
Make sure the external breaker is off before attempting
to make any input or output connections.
By using good quality input and output speaker cables,
the likelihood of erratic signal behavior is reduced to a
minimum. Whether you make them or buy them, look for
good quality wires, connectors and soldering techniques.
Coastal Source includes (2)pairs of RCA input cables
with each CRS amplifier for factory quality input connections.
Other input and output cables are available separately for
completely factory I/O connections.
4:1.Signal grounding
There is no ground switch or terminal on the CRS
amplifiers. All shield terminals of input connections are
directly connected to the chassis. This means that the unit’s
signal grounding system is automatic. In order to limit hum
and/or interference entering the signal path, use balanced
input connections.
In the interests of safety, the unit MUST always operate
with electrical safety earth connected to the chassis via the
dedicated Protective Earth wire.
4:2.Analog audio input connections
Analog input connections are made via the Phoenix MC
1,5/12-ST-3,81 1803675 connector. Signal polarity of analog
input connections is shown in Panel F, p. 6.
Short the Positive (+) and Negative (-) to the Ground
Input terminal on the unused Input channel(s) in order to
avoid picking up noise.
4:2.1.Remote level adjustment
The level of each channel of the CRS amplifiers can be
remotely adjusted by means of a linear 10 kΩpotentiometer
connected to the input LEVEL connector (see Panel D, p. 5)
through a Phoenix MC 1,5/12-ST-3,81 1803675 plug. The
right polarity for the connections is shown in Panel H, p. 6.
When the CH1 MSTR switch is in the OFF position (low)
the remote level potentiometers work independently on
each separate channel.
When the CH1 MSTR switch is in the ON position (high)
the remote level potentiometer of the channel 1 acts as a
master level, controlling the volume of all the four channels.
The remote level controls are in series with the level
adjustment knobs in the front panel.
4:3.Digital audio input connections
The CRS amplifiers accept four input streams from the
Dante connection through the Dante port. Cabling must
comply to TIA/EIA-568-B and adopt the T568B scheme
pinout, as shown in Panel U, p. 9.
In order to implement a Dante network, a computer
running Dante Controller has to be used. Dante Controller
is a software application that manages devices on the
network. CRS amplifiers are automatically discovered and
displayed in Dante Controller with the default identifier
MODELNAME-SERIAL
(e.g. CRS2800-71520).
4:3.1.Input selection and Backup policy
With CRS amplifiers, it is possible to select among two
input signal sources per channel: analog and Dante streams.
The Armonía Pro Audio Suite software provides an interface to
select the proper input source, manage input gain and delay
of the analog and digital sources, in order to compensate
transmission latency and levels.
Furthermore, CRS amplifiers implement a backup policy
aimed to improve reliability against signal fault. By assigning
a bus priority to the two different input sources per channel,
the system is able to automatically switch to a reliable input
connection in case of signal drop or pilot tone mismatch.
4:4.Ethernet connections
The port labeled Ethernet is designed to remotely
control the amplifier via an Ethernet connection through a
personal computer and Armonía Pro Audio Suite software.
A complete interface for signal routing, sound shaping, and
performance fine tuning is provided.
Coastal Source recommend the use of Ethernet Cat5
straight through – patch – cables with pin/pair assignments
TIA/EIA-568-B, i.e. T568B, as shown in Panel U, p. 9.
4:5.Output connections
WARNING: Connecting speakers to the incorrect channels
could cause permanent speaker damage and void all
warranty claims.
CLASS 3 WIRING
Output terminals are hazardous: wiring connection to
these terminals require installation by an instructed
person and the use of ready made leads. Take care to secure
the output terminal before switching the device on.
Output connections are made via the Phoenix
PC 5/ 8-STF1-7,62 1777891: single-ended wirings for lo-Z
loudspeaker and Hi-Z distributed lines connections are
shown in Panel K, p. 6. Bridge-tied connection of lo-Z
loudspeaker is supported on adjacent channel pairs 1-2,
3-4, 5-6 and 7-8; inputs must be physically paralleled as
shown in Panel L, p. 6.
Any mixed configuration of low and high impedance
output loads can be made: in order to set the load
configuration, each channel is provided by four DIP switches
(refer to Panel O, p. 7). CRS Amplifiers are configured to
drive Lo-Z loads by factory default.
4:5.1.Hi-Z 70V/100V operations
Any channel of a CRS amplifier can drive 70V/100V
(Hi-Z) distributed line of loudspeakers. In order to connect
any channel’s output to a 70V/100V line, the rear panel DIP
switch corresponding to the channel must be correctly set
as indicated in Panel O, p. 7.

4:6.Gain selection
The CRS amplifiers can operate with different gain
applied to the input signal. This feature is designed to match
the voltage of the input signal, i.e. allowing to obtain the same
output power at different input levels.

4:7.Lo-Z 2Ωload operation
The CRS amplifiers are optimized for working with 4Ω
output loads but a special configuration allows to connect
low loads down to 2Ω(e.g. in the configuration with three
paralleled 8Ωloudspeakers that provides 2.67Ωload to the
output channel).
The 2Ωswitch (see Panel D, p. 5) allows to activate on
all output channels set to match low impedance (i.e. in Lo-Z
configuration) an operating condition that optimizes the
performance with very low loads, by limiting the maximum
output voltage to 85 Vpeak per channel.
For optimal 2Ωperformance, it is recommended to
select LowZ mode for all the amplifier’s channels
4:8.Diagnostics - GPO - Alarms
The amplifier’s GPO – general purpose output – system
implements triggering signals to broadcast alarms.
CRS amplifiers provide a pair of paralleled general
purpose output connections per channel: one Normally
Open NO and one Normally Closed NC.
The connections are available on the back panel via the
12-pin Phoenix MC 1.5/12-ST-3.81 1803675 connector: see
Panel G, p. 6 for wirings.
These contacts are used to report potentially dangerous
faults or generally unsafe operation conditions by toggling
alarm switches relative to the following events, and any fault
preventing the normal operation of an output channel:
f No AC mains (i.e. system shutdown);
f Thermal stress: the system temperature is too high
and the thermal protection is engaged;
f Short circuit in output wiring: either the loudspeaker or
the line is in short;
f Amplifier is in Standby
CRS amplifiers features further monitoring on pilot tone
and output load: the monitoring and diagnostic interface
is accessible in Armonía Pro Audio Suite software through
the Diagnostic tab in the output ways panel of the selected
channel of the CRS amplifier.
4:8.1.Pilot tone monitoring
Thanks to the built-in DSP, the CRS amplifiers implement
pilot tone detection and alert. Detecting and alerting
features are available for both input and output pilot tones
on each channel.
The detection of a mismatch in the input pilot tone
parameters (frequency and voltage level) can be used to
trigger the backup policy and activate an alert through the
general purpose output switch.
The output pilot tone detection relies on an external
signal passing through the amplifier or the internal post DSP
pilot tone generator; in both cases any mismatch between
the detected signal and the set thresholds triggers the
general purpose output switches.
4:8.2.Output load monitoring
Through the Armonía Pro Audio Suite software it is
possible to set the thresholds on the load impedance, at
given frequency, that trigger the general purpose output of
any channel in the CRS amplifiers.
Coastal Source recommends to use the built-in HPF (High
Pass Filter) when the amplifier is set to drive a distributed
line to prevent loudspeaker transformer saturation which
can considerably degrade sound performance. The HPF
can be activated by means of the DIP switch corresponding
to the channel (see Panel O, p. 7), two cutting frequency are
available 35 Hz and 70 Hz.

CRS amplifiers support star network topology via the
Ethernet port and Dante networking via the Dante port only.
The Ethernet port is designed to allow the remote
control of the amplifier through Armonía Pro Audio Suite
and third party software. The Dante port is reserved to
Dante networking.
7:1.IP addressing
Factory default network settings are DHCP/AutoIP,
in order for the amplifier to self-configure when connected to
an existing LAN or PC. Fixed IP policy can also be adopted
and configured through Armonía Pro Audio Suite.
If a DHCP server is not active within the network,
the amplifier platform initiates a stateless address
auto-configuration (i.e. Zero-configuration networking
methodology – Zeroconf): it self assigns a local numeric
network address (of the type 169.254.x.y – 172.31.*.* for
the secondary network if present – with a subnet mask
255.255.0.0) and automatically distributes and resolves the
host names of the networking devices. For setting a static
IP address please refer to the Armonía Pro Audio Suite user
guide.
7:1.1.IP Addressing troubleshooting
When connecting the CRS to a network environment it
may happen that Armonía Pro Audio Suite does not discover
or import the amplifier.
Usually this is a problem of IP addressing: both Armonia
and the amplifier must belong to the same subnet. If a
DHCP server is present on the network and a CRS amplifier
is in AUTO IP, networking may become unstable.
As a rule of thumb, turn the DHCP server
on before connecting the amplifiers.
IP addressing of a CRS amplifier is established during
the bootstrap: when the amplifier discovers a DHCP
server on the network during the startup, it negotiates the
networking parameters. If the amplifier does not reveal a
DHCP server on the network during the startup, it set itself
in AUTO IP mode.

Armonía
Pro Audio Suite
Armonía Pro Audio Suite is the default configuring
interface that allows system setting and customization of
the CRS amplifiers.
Armonía can be installed on a PC running Windows
(XP SP3 and higher). Freely download Armonía Pro Audio
Suite from the Armonía forum:
https://armonia.powersoft.it/download-armonia/
CRS amplifiers can connect to the PC running Armonía
through a Fast Ethernet connection. In order to start remote
operation the device must be discovered and imported into
the Armonía Workspace. Click on the Discover button in the
Remote entities window, or select it from the Model list and
drag it into the Armonía Workspace.
The callback button (see Panel C, p.5) allows you to
highlight the presence of the amplifier into the Armonía
Workspace.
Once connected to Armonía Pro Audio Suite, a double
click on the amplifier icon in the Workspace will open the
amplifier dashboard. Here it is possible to access and
configure all the features of the CRS amplifier.

8:1.Signal routing and DSP architecture
Signal processing on CRS amplifiers accomplishes
multiple functions that affect the audio signal before power
amplification; the main adjustments include gain, polarity,
delay, limiting and signal equalization; some processing
are related only to particular stages, such as limiting and
damping control that are implemented on the output
section only, or input priority assignment available in the
input section.
The processing architecture is composed of six sections:
f Input source selection. The input section allows you
to manage input gain and delay of analog and digital
sources, in order to compensate transmission latency
and levels. Furthermore the CRS amplifiers implement a
backup policy aimed to improve reliability against signal
fault.
f Matrix. The innovative routing engine of CRS amplifiers
allows any input to be routed to any output. The Matrix
implements a non-boolean rooting architecture allowing
free channel assignment and level adjustment.
f Advanced processing. This allows you to optimize
levels and shape the sound of the input signals. Gain
and polarity adjustment, asymmetric raised-cosine full
parametric filters, delay and mute are available on each
channel routed to the speaker section.
f Speaker equalization. Designed to manage the
configuration presets for multi-way systems, it
implements FIR and IIR full parametric filters.
f Speaker routing. Once properly grouped, the output
channels are presented to the matrix as speakers –
a single row representing a speaker (actually group of
ways) – allowing a high grade of granularity in signal
processing.
f Output processing. This allows fine tuning of output
signals, aiming to optimize the power delivered and the
performance of the single way out. It provides gain and
polarity adjustment, IIR and FIR full parametric filters,
delay, mute, limiting and damping control on each
output channel.
8:2.Purposed workflow
Once the loudspeaker layout has been defined, we
suggest a bottom-up configuration procedure that starts
from the configuration of the transducers layout and goes
up toward the input selection and the definition of the
backup policy.
Shortly, the main steps to follow are:
1. Set Lo-Z and Hi-Z loads and filters on output channels.
2. Load the loudspeaker presets or manually configure the
loudspeaker layout (grouping output channels, limiting,
speaker processing, etc.).
3. Define the routing path and the levels of the signals
from the input channels to the active output channels
(matrix).
4. Select the signal source from the input connections and
define the backup policy (input source selection).
5. Define GPO assignment and alarms thresholds.
10
Through Armonía Pro Audio Suite software it is possible
to set the thresholds on the load impedance, at given
frequency, that trigger the general purpose output of any
channel in CRS amplifiers (see FIG. 5).
