M/S Mode
A 2-channel stereo signal can be transformed
from the L/R (left/right) domain into the M/S
(mid/side) domain and back without any signal
degradation.
In the M/S domain, the two channels representing
the stereo signal contain information on the Mid
(mono) and Side content of the stereo signal.
Equalizing in the M/S domain can, for example,
just affect vocals or instruments centred in the
stereo mix. Or, by boosting the S channel, result
in frequency dependent stereo-base enhance-
ment.
On/Off
Press the “menu” key, then select the “System ->
MS coding” option. This opens the “MS Coding
Setup” menu (see Graphic 5).

The MS mode is activated by toggling the “M/S
on/off” value with key C. The M/S icon will ap-
pear in the top left corner of the frequency re-
sponse window to indicate that M/S mode is ac-
tive.
Setup
Several possible M/S configurations can be acco-
modated for in the EQ1. This can be achieved
with the “M/S Setup” option by pressing key D.
The user is then taken through a procedure to
specify the setup to be used. The “back” and
“next” keys help negotiating within the setup pro-
cedure.
To eq a standard L/R stereo signal in the M/S
domain, the input and output sections are speci-
fied as L/R, while the EQ is set to M/S.
If one decides to decode a M/S recording, for
example, the input would have to be set to M/S
and the output to L/R – the eq section can be set
to either, depending upon which domain one
wants to eq.
Another option is encoding a L/R signal to M/S for
further M/S processing outside the EQ1-MK2.
Then the output will have to be set to M/S and
the input to L/R. Again, the eq section can operate
in either domain.
To compensate for different non-standardized
M/S formats, there is a L/R swap option. This, as
the name implies, will swap the decoded left and
right channels, and will be used when decoding
M/S recorded material to L/R.
