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.
