IMPORTANT SAFETY INSTRUCTIONS The lightning flash with arrowhead symbol, within an equilateral triangle is intended to alert the user to the presence of uninsulated „dangerous voltage“ within the product’s enclosure that may be of sufficent magnitude to constitute a risk of electric shock to persons. The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintance (servicing) instructions in the...
1 Introduction 1.1 Welcome Thank you for choosing an Electro-Voice CPS series amplifier. Please take time to consult this manual so that you can understand all the features built into your Electro-Voice amplifier and fully utilize all its performance capabilities.

CONTRACTOR PRECISION SERIES WARNING: The terminals marked with are hazardous live and the external wiring connected to these terminals requires installation by an instructed person or the use of ready-made leads of cords. HF-Interference (FCC Information USA) 1. IMPORTANT: Do not modify this unit! Changes or modifications not expressly approved by the manufacturer could void the user‘s authority, granted by the FCC, to operate the equipment.
2.5 Ventilation As with all Electro-Voice power amps with fan cooling, the airflow direction is front- to-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.
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 ventilati- on 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.
CONTRACTOR PRECISION SERIES 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.
CONTRACTOR PRECISION SERIES 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.
CONTRACTOR PRECISION SERIES 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.
CONTRACTOR PRECISION SERIES 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.
CONTRACTOR PRECISION SERIES 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.
