Location
Install your CRS Amplifier in well ventilated rack cabinets. Secure both front and rear brackets to the rack. Connect the AC Mains connector to a circuit breaker. Install the amplifier far from EMF emitting devices. Avoid placing the amplifier close to heat generating sources.
Cooling
The ventilation openings must not be impeded by any item, keep a distance of at least 50 cm from the front and rear ventilation openings of the amplifier.
CRS amplifiers implement a forced-air cooling system to maintain constant operating temperatures. Air enters from the front panel, exiting at the back of the amplifier.
The cooling system features variable-speed DC fans controlled by the heat sink mounted sensors. This ensures that fan noise and internal dust accumulation are kept to a minimum.
In the rare event of overheating, 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, leave one rack unit empty every four to guarantee adequate air flow.
Cleaning
Use a dry cloth for cleaning the chassis and the front panel. Air filter cleaning should be scheduled in accordance with the dust levels in the amplifier’s operating environment.
In order to clean the vent filters remove the front cover by firmly gripping the outermost silver panels and pull them outwards
Use compressed air to remove the dust from filters, or wash it with clean water (let the filter dry thoroughly before reinstalling them).
AC Mains Supply
CRS amplifiers implement an 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.
Switching the amplifier On and 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 latest power off.
In order to toggle the amplifier between ON and STANDBY keep pressed the power button for 3 seconds. Please consider that the operating condition can be modified by the REMOTE ON and REMOTE OFF configuration.
Energy Save
The Smart Rails Management technology implemented in the power supply unit allows to reduce the power consumption when the input signal falls under a defined threshold.
When 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.
In order to activate the Energy Save feature, operate the NRG SAVE dip switch on the rear panel.
Breaker Save
This feature may be activated when the power grid is unable to provide enough current to continuously drive the loads, or when the number of amplifier connected to the same outlet is such that one can reach the critical power absorption of the line.
When activated, the Breaker Save 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.
Remote On/Off
Remote ON/OFF is available through the dedicated terminals on the rear panel.
Both terminals respond to the differential voltage between the contacts: a voltage difference in the range 5VDC 24VDC 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, in accordance with the following table.
REMOTE ON Vdiff 5V Vdiff < 3V

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.
A proper combination of the position of two GAIN switches on the rear panel sets the operating gain of the amplifier
CONNECTIONS
Signal Grounding
There is no ground switch or terminal on the CRS amplifiers. 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.
Analog Audio Input connections
Analog input connections are made via the Phoenix MC 1,5/6-ST-3,81 5447900 connector.
Remote Level adjustment
The level of each channel can be remotely adjusted by means of a linear 10 k potentiometer connected to the input LEVEL connector.
When the CH1 MSTR switch is in the OFF position the remote level potentiometers work independently on each separate channel.
When the CH1 MSTR switch is in the ON position the remote level potentiometer of channel 1 acts as a master level, controlling the volume of both channels.
The remote level controls are in series with the level adjustment knobs in the front panel.
Digital Audio Input connection
CRS1K/2K/4K/8K amplifiers feature AES67 and accept two input streams from the dedicated audio over IP port. Cabling must comply to TIA/EIA-568-B and adopt the T568B scheme pinout.
Ethernet connection
The port labelled Ethernet is designed to remotely control the amplifier via an Ethernet connection through a personal computer and Powersoft ArmoníaPlus software.
Powersoft recommend the use of Ethernet Cat5 straight through patch cables with pin/pair assignments TIA/ EIA-568-B, i.e. T568B.
Output connections
Output connections are made via the Phoenix PC 5/4-STF17,62 177859 port.
Any mixed configuration of low and high impedance output loads can be made: in order to set the load configuration, each channel is provided with four DIP switches.
Hi-Z 70V/100V operations
Any channel of can drive 70V/100V (Hi-Z) distributed line 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 set.
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, two cutting frequency are available 35 Hz and 70 Hz.
Diagnostics – GPO – 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 6-pin Phoenix MC 1.5/6-ST-3.81 5447900 connector.
When the amplifier is in normal operating condition the NO contacts are closed, whilst the NC contacts are open, and vice-versa.
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:
No AC mains (i.e. system shutdown);
Thermal stress: the system temperature is too high and the thermal protection is engaged;
Short circuit in output wiring: either the loudspeaker or the line is in short;
Amplifier is in Standby
Self Check
The self check procedure tests the amplifier status and reports the user in case of failures.
After few minutes, at the end of the self check procedure, a combination of lit LED in the LED panel provides information about the amplifier status.
In order to exit the self check test and resume normal operations, press once the self check push button 6 .
If self check cannot be started because of a fault, the check LED will blink fast, whilst a reassuring slow blink is an indication of a completed self check procedure.
CRS1K/2K/4K/8K User Guide | CoastalSource.com 3
Pilot Tone monitoring
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.
NETWORKING
CRS amplifiers support star network topology via the Ethernet port and AES67 dedicated AoIP port.
Signal Grounding
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 ArmoníaPlus.
If a DHCP server is not active within the network, the amplifier platform initiates a stateless address autoconfiguration (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.
Both Armonia and the CRS 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 CRS does not reveal a DHCP server on the network during the startup, it set itself in AUTO IP mode.
ARMONÍAPLUS
ArmoníaPlus 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).
Download ArmoníaPlus for free from the dedicated website:
Input selection and Backup Policy
In CRS it is possible to select among two input signal sources per channel: analog and AES67 streams. ArmoníaPlus software provides an interface to select the input source.
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.
Output Load monitoring
Through the ArmoníaPlus 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.

12V POWER TRIGGER SETUP
1 Standby Mode
With your CRS amplifier plugged in and turned on, press and hold the power button to put the amplifier into standby mode. Once in standby mode, the EQ meters will flash orange at 6 dB/Temp. Note: to access these controls, remove magnetically attached faceplate and foam.
2 Wiring
With the CRS amplifier in standby, you can wire in your trigger using the phoenix connector on the rear panel of the amplifier. Use the left two terminals of the phoenix connector. Since this is a DC connection, it is essential to use the proper polarity. In this connector, the left-most terminal is positive. With the connection now complete, the amplifier will turn on when it detects power via the trigger.
