Up to now we have only covered placing one EQ in each signal path (i.e., EQ1
to M1 and EQ2 to M2). It is possible for both EQs to be assigned to a single
source. Select M1 as the source for both EQ1 and EQ2. In this case EQ2
follows EQ1 and they are in cascade mode. Now you have an 8-band paramet-
ric EQ.
The diagram below shows the signal path with two EQs in cascade mode:
SIDE NOTE:
Current software does not
allow the composite EQ curve
to be shown on one graph.
You must view the EQ1 and
EQ2 curves separately.
At this point you should be listening to the audio source through the console.
Save your work to a SnapShot (either SnapShot #10 or another SnapShot
location if you wish). Review the exercise a couple of times and try making
slight variations to the EQ, pan, or fader levels and save them to SnapShots.
Then, while listening to the audio source, recall different SnapShots and listen
to the effect of the variations you’ve saved.
Unlike conventional consoles which provide 1 fixed insert point, the CS3000/
2000 allows you to build insert points into the signal path when and where
they are required. Each channel can have up to 3 insert points. This could
provide a pair of insert points for a stereo fader and the third insert point could
be used for a mono fader.
Each channel has 4 line inputs (L1, L2, L3, L4) and 3 pre-fader line outputs
(Out1, Out2, Out3). Line 4 or Mic 2 inputs are usually used as multitrack
returns because of their bus/tape switching capabilities. This leaves 3 in/out
pairs to build the 3 insert points, and Out1/L1, Out2/L2, and Out3/L3 are
typically used as these insert send/return pairs.
