The interconnection implies, that the unit that performs the most compression is controlling
the others. To choose which one you want to control, select the attack/release time, the
threshold and the ratio on that unit, and turn the threshold fully counter clockwise on the
reminding compressors.
It is of course possible to have all the interconnected compressors control each other
simultaneously.
NB: Remember to set the ratio control and the gain control in the same position
on the "slaves". Otherwise the stereo image could be shifted during
compression.
The attack/release-control on the slaves will have no effect.
The input/output capability of the side chain-circuit allows up to ten compressors to be
linked together. They are connected in parallel with a standard 1/4" stereo jack/-jack cord
(tip: bus 1, ring: bus 2).
The two-jack socket on the rear panel is connected in parallel and both are input/output.
VU-Meter:
The vu-meter can be switched between output level and compression.
Output gain:
A level control with a gain from off to +10dB is placed at the output of the unit.
MIC PRE-AMP CONTROLS:
GAIN: Coarse: The gain switch has a range from +20dB to +60dB in steps of 10dB.
Fine: The gain switch has a range from 0dB to +10dB in steps of 1dB.
LOW CUT: The highpass filter is selectable between off, 20 Hz (12dB/octave) and
40 Hz (6dB/octave).
PHANTOM: The phantom switch turns the +48V DC power on and off.
The +48V DC is supplied to the microphone input via two 6,81 K  r esi st or s.
PAD: This switch selects between either 0dB or -20dB attenuation in front of the
microphone transformer.
DI: The Direct Input is an unbalanced, high impedance input intended for various
instruments.
It goes directly into the preamplifier and has a gain range of +10dB to +60dB
EQUALIZER CONTROLS:
LOW SHELF:
GAIN: The gain control is continuously variable from 0 dB to 15 dB.
