Using a Compressor in the Insert send/return loop

It may be desirable at times to use a compressor to control the dynamic range of a signal which is being
recorded. The insert send and return loop on the Alpha Channel provides a flexible way if interfacing
with equipment such as this.
- The POST EQ button will determine whether the signal is first compressed and then EQed, or the other
way round. Pressing this will place the send/return loop after the EQ. Note that the behaviour of the com-
pressor can be changed significantly depending on whether it is pre or post EQ.
If you feel that the incoming signal is quite even across the frequency spectrum and does not contain any
significant humps or troughs, it should be fine to send the unequalised signal to the compressor. It may
then be worth lifting the high end of the EQ section up slightly to compensate for the high frequency deg-
radation that compressors can sometimes exhibit.
Where you feel the EQ is needed to first even out the signal, send the signal to the compressor after the
EQ – i.e. The POST EQ button down.
After the EQ, filter and insert loop the signal is sent to the Alpha Channels outputs (analogue and digi-
tal).
Note: By engaging the Lite Limit button the INSERT SEND level is dropped by 12db. This is in order to
give the unit enough headroom during limiting action.
This will however affect the compressor settings quite significantly. If you have set up the compressor
and subsequently engage the Lite Limit function then the compressor may well need to be adjusted
again. In these cases, moving the compressor threshold down by 12db and its make-up gain up by 12db
should provide the same behaviour as before the Lite Limit was activated.
- The signal is presented to the front panel input and amplified accordingly.
- Pressing the INSERT IN button will not only send the pre-amplified signal
to the compressor but will return it back to the Alpha Channel for further
processing.
