Rotate the THRESHOLD control anticlockwise until the BELOW THRESHOLD
meter is fully illuminated and an appropriate amount of gain is indicated on the
GAIN REDUCTION meter. This operation will be accompanied with a drop in
output level, as indicated by the OUTPUT METER. The output GAIN CONTROL
should now be adjusted to reinstate the output level. The levels of the
uncompressed input signal and the compressed output signal can now be
compared on the output meter by operating the METER INPUT switch.
Final adjustments of the controls can then be made to suit particular requirements,
including the RATIO, ATTACK, and RELEASE controls. The 'auto' position of the
release control provides for a program related operation of the dynamics of the
unit, and will be accepted for most general purpose applications. Should a tighter
or looser requirement be necessary, then both the attack and release controls can
be set individually to suit.
The experienced engineer will be able to set the compressor controls to near
optimum position for any source material with the BYPASS switch out, so that the
compressor can be 'dropped' into a live performance without disturbance.
