1.4 Features and Description
Electro-Voice CONTRACTOR PRECISION SERIES Series amplifiers offer a package of reliable high output power, high
efficiency and legendary pro audio performance. They are the premium choice as system drive for a variety of Electro-Voice‘s
installation loudspeakers like e.g. EVI, FRi, FRX or Variplex families. Their comprehensive protection system includes circuitry
against overheating, overload, short circuit, HF and DC as well as back-EMF and inrush current. Loudspeakers are protected
by turn-on-delay relays.
1.5 Responsibility of the User
Speaker System Damage
CPS power amps provide extremely high power output that might be dangerous for human beings as well as for the
connected speaker systems. High output voltages can damage or even destroy the connected speaker systems, especially,
when the CPS amplifier is operated in bridged mode. Prior to connecting any loudspeakers, make sure to check the speaker
system’s specifications for continuous and peak power handling capacities. Even if amplification has been reduced through
lowering the input level controls on the amplifier’s front panel, it is still possible to achieve full power output with a sufficiently
high input signal.
Danger at the Loudspeaker/Power Outputs
CPS amplifiers are capable of producing dangerously high voltage output that is present at the output connectors. To protect
yourself from electric shock, do not touch any blank speaker cables during operation of the power amp.

2.2 Operating Voltage
The power amplifier receives its power supply via the MAINS IN connector. Only the provided power cord may be used.
During installation, always separate the power amplifier from the mains. Connect the power amplifier only to a mains network,
which corresponds to the requirements indicated on the type plate.
Mains Operation & Resulting Temperature
The power drawn from the mains network is converted into output power to feed the connected loudspeaker systems and into
heat. The difference between power consumption and dispensed power is called power dissipation (Pd). The amount of heat
resulting from power dissipation might remain inside of a rack-shelf and needs to be diverted using appropriate measures.
The tables on page 31 allow the determination of power supply and cabling requirements. The tables are meant as auxiliary
means for calculating temperatures inside of a rack-shelf system/cabinet and the ventilation efforts necessary.
The column Pd lists the leakage power in relation to different operational states. The column BTU/hr lists the dispensed heat
amount per hour. Power consumption is direct proportional for other mains voltages. The following conversion factors are
meant for easy conversion: 100V = 2.3; 120V = 1.9; 240V = 0.96
2.3 Mains Switch
The Mains Switch on the front panel separates the power amp from the mains. Turning the
Mains Switch to ON starts booting up the power amp. A soft start circuit compensates
mains inrush current peaks and thus prevents triggering AC mains fuse when switching on
the amplifier. Speaker system switch-on is delayed by approximately 2 seconds via output
relays, effectively suppressing any possible power-on noise, which otherwise might be
heard through the loudspeakers. PROTECT-LED light and fans are at high speed during
this delay. This indicates all protections are working fine.
2.4 Mounting
CPS amplifiers have been designed for installation in a conventional 19-inch rack case. Attach the power amp with its frontal
rack mount ears using 4 screws and washers as shown in following illustration.
Additionally securing the amplifier at the rear becomes necessary, if the rack case in which the power amplifier has been
installed will be transported. Failure to do so may result in damage to the power amplifier as well as to the rack case. Attach
the power amp as shown in the illustration using 4 case nuts and screws. Brackets for securing the power amplifier are
available as accessories.
2.5 Ventilation
As with all Electro-Voice power amps with fan cooling, the airflow direction is frontto-rear, obviously because there is more cold air outside of the rack case than
inside. The power amplifier remains cooler and dissipating the developing waste
heat in a specific direction gets easier. In general, setting up or mounting the
power amplifier has to be done in a way that fresh air can enter unhindered at the
front and exhausted air can exit at the rear. When installing the power amp in a
case or rack system, attention should be paid to these details to provide sufficient
ventilation. Allow for an air duct of at least 60 mm x 330 mm between the rear
panel of the power amplifier and the inner wall of the cabinet/rack case. Make
sure that the duct reaches up to the cabinet’s or the rack case’s top ventilation
louvers. Leave room of at least 100 mm above the cabinet/rack case for ventilation. Since temperatures inside of the cabinet/
rack case can easily rise up to 40 °C during operation of the power amp, it is mandatory to bear in mind the maximum
allowable ambient temperature for all other appliances installed in the same cabinet/rack case.

Owner‘s Manual
CONTRACTOR PRECISION SERIES
CAUTION:
Blocking/closing the power amp’s ventilation louvers is not permissible. Without sufficient
cooling/ventilation, the power amplifier may automatically enter protect mode. Keep ventilation louvers free from dust to ensure unhindered airflow.
Do not use the power amplifier near heat sources, like heater blowers, stoves or any other heat
radiating devices.
To ensure trouble-free operation, make certain that the maximum allowable ambient temperature of +40°C is not exceeded.
For fixed amplifier installations in a device control room that incorporate a central air-cooling system or air conditioners,
calculating the maximum heat emission may be necessary. Please also take notice of the information on page 31.
2.6 Groundlift
The ground lift switch allows eliminating noise loops. When operating the power amplifier together with other
equipment in a rack case, setting the switch to the GROUNDED position is recommended. Set the switch to
UNGROUNDED, when the power amplifier is operated together with appliances with differing ground
potentials.
2.7 High Pass Filter (HPF)
The Hi-Pass filter (50 Hz, 18 dB/oct) allows effective attenuation of low frequency audio signals, which could
cause saturation problems with connected output transformers. Set the switch to the 50Hz position for
activating the High Pass Filter. Set the switch to the OFF position if no attenuation of low frequency audio
signals is required.
2.8 Power on delay
The ON DELAY switch at the amplifier rear panel allows selecting the power on delay time.

2.9 Selecting the Mode Of Operation and Audio Output Cabeling
The MODE switch on the power amp‘s rear panel defines how the audio inputs handle the input signals. Possible settings are
DUAL, PARALLEL or BRIDGED.
DUAL
In DUAL mode, the two channels of the power amplifier work independent from each other. This mode
of operation is being used for all 2-channel applications, like stereo operation. Using the input level
controls on the power amp’s rear panel allows independently adjusting the channels’ amplification.
PARALLEL
In PARALLEL mode, the inputs of channel 1 and channel 2 are directly electrically linked. The audio
signal has to be applied to the input connectors of channel 1. Using the input level controls to
independently control the amplification of the two channels is still possible because only the channels’
inputs are linked. PARALLEL operation is the mode of choice, whenever the same input signal drives
multiple power amp channels of a large system installation.
CAUTION:
In PARALLEL mode, the input signal has to be fed to input channel 1 only.
See illustration right for connecting speakers in DUAL or PARALLEL
mode. The correct connection is also indicated at the amplifiers rear
panel.
BRIDGED
In BRIDGED mode both amp channels work in push-pull operation to provide doubled output voltage.
The audio signal has to be applied to the input connectors of channel 1, amplification is set via input
level control of channel 1 only.
CAUTION:
In BRIDGED mode, the input signal has to be fed to input channel 1 only. Amplification is set
via input level control of channel 1 only.
In BRIDGED mode operation, it is not allowable for the load connected to fall below a value of
4 ohms. Extremely high voltages can be present at the output. The connected speaker systems must be able to handle such voltages. Make sure to completely read and fully observe
power rating specifications of the speaker systems to be used and to check them against the
output power capacity of the power amp.
Setting the MODE switch on the power amp‘s rear panel to BRIDGED lets the power
amplifier run in bridged mode operation and speaker connection has to be
established using pins 1+ und 2-, see illustration right. The correct connection is also
indicated at the amplifiers rear panel.

2.10 Audio Input Cabeling
Inputs are electronically balanced. Whenever possible, using balanced audio signal feeds at the input of the power
amplifier is always preferred. Unbalanced connections should only be used if the cables are very short and no
interfering signals are to be expected in the vicinity of the power amplifier. In this case, bridging the screen
(shielding) and the pin of the inverting input inside of the connector is mandatory. Otherwise, a 6 dB drop in level
could result. Please also see following illustration. Due to their immunity against external interference sources,
such as dimmers, mains connections, HF-control lines, etc., using balanced cabling and connections is always
preferable.

3 Operation
3.1 Volume Control
In DUAL and PARALLEL mode, the level controls LEVEL on the power amp’s rear panel are used to control
the amplification of the corresponding channel. Turning the control to the right increases and turning it to the
left decreases the volume. In BRIDGED mode operation, the output volume of the power amp is only
controlled by the CH 1 level control. Any changes in the setting of the CH 2 level control are ignored.
3.2 Indications
PROTECT
The PROTECT LED lights indicating that one of the internal protection circuits against thermal overload,
short-circuit, Back-EMF, HF-occurrence at the output, etc., has been activated. In that case, the output
relays separate the power amps from the load connected to prevent the connected loudspeaker systems
and the power amplifiers as well from being damaged. Whatever caused the fault – e.g. a short-circuited
speaker cable – needs to be remedied. In case of thermal overload you have to wait until the power
amplifier automatically regains normal operation.
MUTE
The MUTE LED lights red whenever the power amp’s output signal is being muted, which happens when
manually muting the output signal via IRIS-Net™.
-30dB...LIMIT
Level indication is realized via vertical LED chains on the power amp’s front panel that individually indicate
the actual levels of each channel at -30dB, -10dB and -3dB below full modulation. The LIMIT LED lights as
soon as the integrated dynamic audio limiter is activated and the power amplifier is driven at the clipping
limit or generally at its maximum capacity. Short-term blinking is not a problem, because the internal limiter
controls input levels of up to +21 dBu down to a THD of approximately 1 %. If, on the other hand, the LIMIT
LED light constantly, reducing the volume is recommended to prevent the loudspeaker systems connected
from being damaged by probable overload.
POWER
The POWER LED lights green when the power amplifier is on. If the POWER-LED does not light, despite
the fact that the amplifier has been switched on, this indicates that the power amp is not connected to the
mains or the primary fuse has blown.
STANDBY
The STANDBY-LED lights yellow when the power amp is in standby mode. Standby mode reduces the
amp’s power consumption to an absolute minimum. Activating the standby mode is possible via IRISNet™
or the POWER REMOTE port at the amp‘s rear panel.
IRIS-Net
The IRIS-Net-LED lights blue if an IRIS-Net™-compatible remote control module has been installed in the
power amp’s extension slot and successful data communication has been established. The IRIS-Net LED
blink slowly whenever the “Find” function in IRIS-Net™ is being used to locate a power amplifier in the rack.

3.3 Standby Mode (POWER REMOTE)
POWER REMOTE provides a simple way to remotely power-on/off the power amplifier. The POWER
REMOTE function is only useful for appliances not employing a Remote Control Modul. Controlling CPS
amplifiers with Remote Control Module installed per POWER REMOTE is not recommended.
Leaving the pins of POWER REMOTE socket open the appliance power is switched on. When connecting
the pins the applicance enters standby mode.
3.4 Fan Cooling
The power amplifier has two fans. The fans are switched in three performance-optimized levels, i.e. they are not running
permanently but the speed of the fans is controlled depending on the temperature. That in return ensures very silent running
during idle state.
The temperatures of the power amps‘s channels are registered and monitored individually.

4 Options
Installing one of the optionally available extension modules in the extension slot on the rear panel lets you expand the power
amp’s functional range. As an example, the following paragraphs describe the RCM-810 Remote Control Module. Please
read and follow the instructions provided in the documentation that you have received together with each extension module.
4.1 RCM-810
System Description and Features
The RCM-810 Remote Control Module is a digital controller module for live sound reinforcement, PA and fixed installation
applications. Installing the RCM-810 turns a conventional amp into a remote amplifier, which, at any time, provides complete
overview of the overall system status and control of all system parameters.
RCM-810 modules allow the integration of amplifiers into a remote control network with up to 250 units. This offers the
possibility to control and monitor an entire PA system from one or more PCs using the IRIS-Net - Intelligent Remote &
Integrated Supervision - software package. All operational states, e.g. power-on status, temperature, activation of protections,
load impedance, etc., are centrally registered and displayed in IRIS-Net. This provides the possibility to react and to
selectively intervene even before critical operational states arise. Programming an automatic reaction, when specific
thresholds are being exceeded or fallen below, is also possible.
All parameters, like power on/off, muting, etc. can be
controlled in real-time and stored in the amplifier. In the
event of network failure or loss of power, all settings stay
intact, independent of the control by the network.
Furthermore, the RCM-810 provides a control port with
freely programmable control inputs and control outputs.
Control inputs (GPI's) allow the connection of switches.
IRIS-Net offers the possibility to program a variety of logic
functions for the inputs. Control outputs (GPO's) allow the
connection of external components, which, for example, are
used to signal specific states to peripheral equipment.
Consequently, an amplifier with a RCM-810 module
installed corresponds to highest safety requirements. For
further details about configuration, control and monitoring of
amps with installed RCM-810 modules, please refer to the
documentation of the IRIS-Net. The latest version of IRIS-Net is available at www.electrovoice.com.
Controls and Connections
Illustration 4.1: Controls and Connections of the RCM-810
1 ADDRESS Selector Switch
The two address selector switches are for setting the network address of the RCM-810. CAN networks
support addresses in the range of 01 to 250 (FA hex). Addressing has to be carried out in the hexadecimal
number system. The LOW selector switch sets the lower digit, while HIGH sets the higher digit.
CAUTION:
Each address may exist only once in a system. Otherwise, network conflicts may arise.

Table 4.1: CAN addresses
Address 0 (00 hex, delivery status) disables remote communication between the RCM-810 and the bus. The module does not
appear in the system, even though it is physically connected to the CAN-bus.
2 STATUS LED
The STATUS-LED is for monitoring the communication on the CAN bus. The LED blinks rhythmically every 3
seconds, when the module’s address is set to “00“, which means that it is disconnected from the CAN bus
and software control. The LED blinks rhythmically in intervals of one second, when an address in the range of
01 to 250 has been assigned to the module and there has not yet been any activity on the CAN bus. As soon
as communication on the CAN bus is recognized, the LED lights for at least 100 ms, when the power
amplifier sends data on the CAN bus.
3 REMOTE CAN BUS Connection
The RCM-810 module provides two RJ-45 sockets for connecting to the REMOTE CAN BUS. These sockets
are connected in parallel and serve as inputs as well as for daisy-chaining the devices on the remote
network. Cabling in a rack system can be established using commercially available RJ-45 network cables.
However, CAN guidelines have to be observed for longer cable lengths. Both ends of the CAN-bus must be
terminated using 120 Ω terminating plugs.
The CAN bus allows using different data rates, whereas the data rate is inversely proportional to the bus
length. For smaller network setups, data rates can be as high as 500 kbit/s. For broader networks, reducing
the data rate becomes necessary (down to the minimum data rate of 10 kbit/s).
NOTE:
The data rate of the CAN bus is preset to 10 kbit/s.
The following table illustrates the relation between data rate and bus length or network size. The use of CAN repeaters is
strongly recommended for busses that exceed 1000 meters in length.

4 CONTROL PORT
The CONTROL PORT of the RCM-810 provides two control inputs, two control outputs and reference
connections for +5V and ground. The control inputs are configurable via IRIS-Net™. They can be used for
example for switching between power on / standby modes. The two control contacts IN1 and IN2 are
internally connected via pull-up resistors and carry +5V (open). The control inputs can be activated using
external switches, pushbuttons or relays to connect them to ground potential (pin 3). The two control outputs
OUT1 and OUT2 are open collector outputs, which are highly resistive in the non-active state (off). In active
state (on) the outputs are connected to ground. The control outputs are configurable via IRIS-Net™ and are
used to signal internal states. LEDs, indicators or relays can be driven directly. The +5V reference connector
provides voltage supply for connected components.
CAUTION:
The maximally allowable current at the +5V output is 200 mA.
