PROCHANNEL CONTROL EXPLANATIONS.

'INPUT GAIN' changes the audio amplification of the input amplifiers of the
ProChannel. Too little gain and the sound will be too quiet and electronic
background noise from various sources could become a problem; too much
and the ProChannel could become overloaded and distorted.
'
COMPRESSION' simply adds gain to the compression sidechain and so
increases compression. In simple terms this changes the 'threshold' of the
compression although with this compressor the 'threshold' is not clearly
defined; the compression starts very gradually and the compression ratio
changes with programme content and volume.
For practical purposes, winding up the compression control increases the
amount of compression. In use you will find that musically, all controls are
interrelated.
'ATTACK' (push button) sets the time that the compressor takes to act.
pressed in (fastest) it's possible to make it 'overshoot' on some percussive
programme material: This means that the compression electronics are
driven hard before the gain has been controlled by the light cells. The cells
catch up and over-compress momentarily giving a tiny dip immediately
following the start of the 'note'. This is best demonstrated when recording
drums. Used sparingly this can contribute to musical drive.
Slower attack (button out) is used where the compression needs to be less
obvious.
'RELEASE' sets the time during which the path gain returns to normal after
compression. Generally, the longer the time, the less obvious is the
compression.
'DRIVE' is the enhancer control that passes high frequencies to a separate
compressor inside the enhancer circuitry. It controls the source of the
enhancement signal.
'Q' is a control for a tuned circuit which 'resonates' the enhanced effect.
'ENHANCE' is the control that sets the amount of enhancement effect that
is mixed back into the main audio signal path.
'OUT VOL' is simply a volume control for the output of the ProChannel. It
operates after the LED VU meter so does not affect the overload margin of
the ProChannel.
