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

This device must be powered exclusively by earth connected mains sockets in electrical networks compliant to the IEC 364 or similar rules.
▶ Install the unit into a rack cabinet.
▶ A sectioning breaker between the mains connections and the amplifier should be installed inside the rack cabinet.
▶ Properly fit the AC mains plug to the amplifier inlet.
▶ Before powering this amplifier, verify that the correct voltage rating is being used.
▶ Verify that your mains connection is capable of satisfying the power ratings of the device.
▶ Do not use this amplifier if the electrical power cord is frayed or broken.
▶ 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 lock the output terminal before switching the device on.
▶ To avoid electrical shock, do not touch any exposed speaker wiring while the amplifier is operating.
▶ Do not spill water or other liquids into or on the amplifier.
▶ No naked flame sources such as lighted candles should be placed on the amplifier.
▶ Do not remove the cover. Failing to do so will expose you to potentially dangerous voltage.
The manufacturer cannot be held responsible for damages caused to persons, things or data due to an improper or missing ground connection.
▶ 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.

3:5.AC mains supply

CRS amplifiers implement a universal switching mode power supply with power factor correction operating in the range from 100VAC up to 240VAC ± 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).

AC mains connections must be performed only by professional or qualified personnel

ording to local electrical authorities guidelines.

This device must be powered exclusively by earth connected mains sockets in electrical works compliant to the IEC 364 or similar rule

Coastal Source recommends plugging the CRS Amplifier into a 20A rated breaker.

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.

Energy Save		115 V AC mains 230 V			AC mains

	AUTOSTBY	0.46 A	20 W	53 VA	0.46 A	20 W	106 VA

TAB. 1: Idle consumption.

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 *Time out time is selectable via Armonia in DSP+D Versions

(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).

3:6.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).

FIG. 1: Press and hold the power button for 3 seconds to toggle between ON and STANDBY.

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 5V_DC - 24V_DC triggers the control. Any voltage exceeding 28V_DC 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.

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 kΩ potentiometer 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.

CLASS3 WIRING

CLASS3 Output terminals are hazardous: wiring connection to WIRING 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.

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.

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.

	GAIN	Input sensitivity @ 8Ω load
		Vpeak Vrms dBu
2800/4	26 6.92 4.9 16.0
	29 4.90 3.47 13.0
	32 3.46 2.45 10.0
	35 2.45 1.74 7.0
1400/4	26 4.89 3.46 13.0
	29 3.48 2.46 10.0
	32 2.45 1.74 7.0

4:7.Lo-Z 2Ω load 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 8Ω loudspeakers that provides 2.67Ω load to the output channel).

The 2Ω switch (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 V _peak per channel.

For optimal 2Ω performance, 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:

▶ 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

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.

Networking

7

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 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:

▶ 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.

▶ 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.

FIG. 10: Armonía Pro Audio Suite.

▶ 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.

▶ Speaker equalization. Designed to manage the configuration presets for multi-way systems, it implements FIR and IIR full parametric filters.

▶ 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.

▶ 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.

8:3. Live Impedance

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).

Speaker Configuration

9

Utilizing the Armonía Pro Audio Suite, Coastal Source ships all CRS amplifiers with a custom DSP configuration for the exact speaker setup that was ordered with the amplifier. Each pre-loaded speaker preset has been specially tuned to optimize performance from the amplifier and speaker itself. The top of the amplifier bears a Speaker Configuration label that outlines the programmed output configuration based on your original order.

In addition to the pre-loaded speaker presets, each CRS amp ships with the preset for the entire Coastal Source speaker line. If the system changes down the road, contact Coastal Source for instructions on how to change presets from one speaker type to another. This can be done quickly utilizing the Armonía web app.

NOTE: Coastal Source outdoor audio systems are the clearest and most efficient on the market, but they are not designed to run at 100% volume full-time. If the system is going to be played at loud volumes for an extended period of time, Coastal Source recommends setting the volume to 75-80%.
