Congratulations!
With buying a Electro-Voice CP-SERIES power amplifier you have chosen an appli-
ance that employs most advanced technology.
CP-Series power amps combine outstanding audio performance, highest reliability and operational
safety.
The audio performance of CP 1200 power amp is simply extraordinary. Optimised power supply units
employing low-leakage toroidal transformers provide extensive headroom far above the stated nominal
output. At the same time this contributes to a reduction in weight and power dissipation.
The CP 1200 is designed in Class-AB technology, have been designed to fulfil even the most demanding
requirements of touring applications. The CP 1200 amp is protected against thermal and electrical
overload, short circuit and the occurrence of HF/DC at the outputs. Back-EMF-Protection eliminates
the risk of the output transistors being damaged by electrical energy back-feed. The power outputs are
switched via relay with a time delay during soft-start. An inrush current limiter prevents mains fuses from
blowing.
Mechanical construction and workmanship also comply with the highest precision manufacturing
standards. The rigid sheet steel chassis even resists the most wearing tour operation. Two three-speed
high performance fans (off/slow/fast) guarantee outstanding thermal stability at absolute low running
noise. The ventilation is directed front-to-rear allowing trouble-free operation even in smaller amp-racks.
The electronically balanced inputs are carried out via XLR-type connectors (female). Direct-Outs for
through connecting the audio signal are also provided via XLR-type connectors (male). Input routing
allows selecting DUAL (stereo) or PARALLEL (mono) operation mode. By means of the separate
BRIDGED OUT-connector and a Bridged Mode-switch, switching to „Mono Bridged”-operation is truly
uncomplicated as well.
The recessed mounted dB-scaled level controls ensure reliable protection against mechanical damage.
These particularly precise, secure to operate detent-potentiometers are located on the front panel.
The easily readable LED display provides a quick overview of the power amp’s current operational
status. The power outputs CHANNEL A, CHANNEL B and BRIDGED OUT are carried out as extremely
durable SPEAKON-type connectors. Also located on the rear panel is a Ground-lift switch, which helps
eliminating ground-noise loops by separating the power amp’s enclosure from circuit ground. In normal
operation, the CP 1200 power amp is capable of driving loads as low as 2ohms. In Mono-Bridged mode
the allowable minimum load is 4ohms.
CP-Series power amps provide the opportunity for retrofitting an internal analogue signal processor
board with x-over and filter functions.
This owner’s manual outlines and explains several other features of your CP 1200 power amplifier.
Please, make sure to carefully read all of it and mind the instructions.
