7 The 8-digit GAIN REDUCTION meter indicates how effectively the gain is reduced by the compressor,
within a range from 1 to 30 dB.
8 The 8-digit INPUT/OUTPUT LEVEL meter informs you—depending on the setting of the I/O METER
switch—about the current input or output level, within a range from -24 to +18 dB. When the switch is
set to IN (not engaged), the meter reads the input level, when it is OUT, the output level is displayed. The
meter is referenced to the operating level (-10 dBV or +4 dBu) adjusted with the OPERATING LEVEL
switch on the back.
9 The peak limiter limits the signal to a level adjusted with the THRESHOLD control. Owing to its
extremely fast response (“Zero” attack), the limiter is capable of limiting signal peaks without audible
distortion. Whenever the signal is limited for more than 20 ms, the overall level is reduced for about 1
second to avoid heavy and thus audible signal distortion.
+
When you use the peak limiter as a protective device against signal peaks, the THRESHOLD
control should be set in combination with the OUTPUT control in the compressor section so
that the peak limiter responds rarely or not at all. Thus, only real signal peaks will activate the
limiter circuit. However, to produce creative sound effects, the peak limiter can be
deliberately set to lower levels.
10 The LIM LED lights up as soon as the limiter function is activated.
11 The MULTICOM PRO converts two channels to stereo mode by engaging one of the COUPLE switches,
where the left of the channels assumes the control of both audio channels, i.e. the control signal of
channel 2 is replaced with that of channel 1. By pressing the COUPLE switch, you override all the
controls and switches of channel 2 (or 4) with the exception of the IN/OUT and SC Filter switches as well
as the peak limiter’s THRESHOLD control. The controls of channel 1 (or 3) take over all functions of
channel 2 (or 4).
