3.13.2. Case 2: stereo recording using M/S microphones
In this case, M/S stereo microphone couples are used (typically the association of a
directional cardioid transducer for the “M” channel and a bidirectional “figure of 8”
transducer for the “S” channel), but the output of the mixer is in standard stereo
format.
One way to do that is to configure inputs 1 and 2 in M/S mode, which will then feed
the mix buses in normal stereo mode, just as in the previous example.
Let us consider here an alternate way of working, where the inputs are left M/S
encoded to feed the mix buses. Instead of left and right, the mixer buses now
actually process M (Mid) and S (Side) signals. In order to output normal stereo
signals, L/RlM/S matrixing must be applied at the outputs; this can be activated in
the “Outputs” sub-menu. Only the analog and USB outputs are so decoded to
normal stereo format.
Matrixing is also needed for monitoring a normal stereo signal on the headphones
(monitoring set in “M/S” position), except for monitoring the output “OUT”
because it is already decoded to L/R format.
With this arrangement, note that, unlike the analog and USB outputs, the digital
outputs (AES and Toslink) stay encoded in M/S format, which allows subsequent re-
work on the stereo image in post-production.
