1. Level Control To prevent unauthorized operation of the level controls on the CPS3 and CPS4, they are prov ided with screwed-on protective cover lids. When shipped from the factory, the detented potentiom eters are set to their clockwise limits. Thus, the input signal is not attenuated.
POWER AMPLIFIER INPUTS Parallel to the XLR-type inputs, output connectors are provided, offering the opportunity to feed additional power amplifiers with the same signal. The inputs are electrically balanced with pin-assignment according to the IEC 268 standard.
POWER AMPLIFIER OUTPUT CONNECTORS SPEAKON output connectors are provided for the power amplifier channels A (left) and B (right). The Bridged Out Connector for bridged operation is sealed with a plastic cover to prevent connection errors. LIMITER The time constant of the built-in limiter to avoid overdri - ving is adjustable.
