The A2 can be used as an insert into a mixing console for dynamic processing or as a
mixdown compressor / EQ, or simple mastering solution.
Using as an inserted dynamic effect
Many mixers have sockets called ‘insert points’, which allow processors such as
dynamics devices and EQs to be patched in-line into the mixer signal path at various
points.
The mixer’s channel insert point usually ‘sends’ the input signal out directly after the
mixer’s preamp stage - allowing connection to the line input of the A2 - and then
returns the processed signal from the line output of the A2 back into the mixer at the
same point in the signal path. This is commonly achieved using a special insert cable
(sometimes known as a ‘Y’ lead or split lead - usually a stereo 0.25” jackconnector at
one end split into two mono jack or XLR connectors - one for send and one for
return).
The most likely positions that insert points are located on a mixer are in the channel,
group and stereo master sections. Patching the A2 into the channel insert point means
that any signal passing through that channel will pass directly though the A2.
Compressing a vocal already recorded on your multitrack recorder or DAW, for
instance, can be achieved by connecting the multitrack or soundcard outputs to the
channel tape return inputs of your console, then connecting one channel of the A2 into
the relevant console channel insert point.
The off-tape signal will then be fed into the A2’s line input via the mixer insert ‘send’
connection. The line output of the A2 connects back to the insert ‘return’ connection,
thus returning the processed signal to the mixer and ensuring continuous signal flow.
Group insert points are used to process sub-grouped signals such as drums or backing
vocals. It’s common to mix an entire drum kit to a stereo group, and then use a pair of
group faders to control the overall level, rather than having to adjust each individual
drum level. If you then wish to compress the overall stereo kit signal, you can connect
a stereo linked A2 to the relevant group insert points, using the same ‘send and return’
technique as the channel insert.
You could also feed the output of your soundcard directly through the A2 and then
back out into your soundcard inputs to record the compressed / equalized signal back
in.
Using to process your stereo mix / mastering
Having processed individual tracks while recording, it is common to apply some
compression to the stereo mix while mastering it.
Even if you are not fully mastering, doing this will help fatten the sound further and
control levels. It is essential for overall balance and dynamic range of the finished mix
and is necessary to balance levels for radio or for mastering a CD or vinyl.
