Press the INTERACTIVE switch to change from hard knee to IKA characteristics. IKA provides a
very subtle and musical compression of the program material and should therefore be used whenever
compression should be more or less inaudible.

The SC FILTER switch activates a high-pass filter in the side-chain path and thus limits the influence of
low frequencies on the COMPOSER PROs control processes.

The 12-digit GAIN REDUCTION meter indicates how effectively the gain is reduced by the compressor,
within a range from 1 to 30 dB.
18
The 12-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 -30 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.
4.3 Peak Limiter Section
Fig. 4.4: Control elements of the peak limiter section

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.

The LIM LED lights up as soon as the limiter function is activated.
