Overview

The CPA12 is a professional single channel 100V power amplifier with a power of 120 Watt, especially designed for most common 100V PA systems and perfect to be used in combination with the CPR12 pre-amplifier. It is designed as a no-nonsense amplifier with only the necessary controls and connections. This creates great simplicity in use and installation. There are several power output taps available for use in 100V, 70V and even 4 Ohm Low impedance installations and they are fitted with an advanced multipurpose protection circuit. The protection circuit detects DC malfunction, short circuit, overheating, overload and limits the signal when necessary. Another present feature is the 24 V DC connection for powering the amplifier with emergency power when the main power is shut down. At the back of the amplifier, there are trim potentiometers to set the input level, a high pass filter switch and a ground lift switch provided. The input connection is made with balanced XLR connectors and there is a signal output for linking with other amplifiers. The steel 19″ housing has a height of 2 HE.
