1 CH-1: Input level controller for channel 1
Use the input level controllers CH-1 and CH-2 (4) on the front panel to control the
signal amplification in the respective channel. If possible, turn this control fully to
the right stop (= 0 dB attenuation) for optimal headroom. Professional power
amplifiers then output their rated power, if the input voltage is 0.775 V resp. 1.4 V
(depending on the position of the switch for the input sensitivity [19]).
2 / 3 PEAK: Indicator for signal / maximum level
These LED chains indicate the output power of the device in the respective. The
PEAK indicator lights up when the output power reaches its maximum. If this indi‐
cator lights up continuously, the volume of the respective channel must be
reduced. To do so, turn to the input level knob counter-clockwise.
4 CH-2: Input level controller for channel 2
Input level controller for channel 2, functionality is equal to point (1).
