APPENDIX 12
The Channel G Compressor/Limiter is one of only two compressors in the world
(the other is the API 225 Compressor) that allows the user to switch between
feed-forward and feedback compression.
So why should feedback compression be used today? This type of compression,
while susceptible to pumping or breathing e ects, can be useful in addressing
certain dynamic range ‘problems’. For example, suppose you needed to process
an aggressive lead vocal that uses a wide dynamic range: If you compress
this heavily, even the softest of knee shapes will not alleviate the unwanted
‘compressed vocal’ e ect that typically results from such heavy compression.
Using the compressor output as the key signal, the transition between the
compressed and uncompressed signal is minimally di erent. Because the key
signal is already compressed, the compressor will trigger more gently – and
this can produce a more desirable result.
Channel G Equalizer
The Channel G Equalizer is based on McDSP’s FilterBank plug-in with
improvements including a greater boost/cut range and switch-able parametric/
shelving EQ sections.
The Controls
The Channel G Equalizer provides five bands of console-style parametric/
shelving EQ, together with a high-pass  lter and a low-pass  lter. The LF and
