CL Series

FRONT PANEL

The dB-calibrated level controls are implemented as ultra-precise detent potentiometers that are recessed in the front panel to protect them from accidental contact. Power, Protect, Signal and Limit LEDs provide a quick overview of the operating status.

REAR PANEL

The electronically balanced XLR IN / OUT sockets are provided for direct operation with professional mixing consoles and signal processors. All the models in the CL series are designed for a Constant Gain of 32 dB.

The power outputs for Channels A and B are on Speakon connectors. The signal of Output B is ad- ditionally available on pins ±2 of Output A, so that with 4-pin wiring a two-way system can be driven.

A Ground Lift switch is also provided to separate the chassis ground from the signal ground in order to eliminate ground loop hum.

SAFETY CIRCUITS

The complete CL series is equipped with protections against overheating, overloading, short-circuits, DC and HF as well as a Back-EMF protection. With the Soft Start system, the power outputs are switched on via a relay when a safe operational state has been reached and a power-up delay prevents the mains fuses being activated.
