Ganged /Unganged
The DS1-MK3 allows for independent parameter
settings in channels 1 and 2 ( ). If the ganged
key is lit, both channels operate with the same
parameter set.
If the ganged key is not lit, the two channels can
operate with different parameters. The CH1/CH2
/ M/S key assigns the knobs and the display to
the appropriate channel, i.e. key not lit assigns
CH1 or M and key lit assigns CH2 or S.
In ganged mode the CH1/CH2 M/S key can be
used as a A/B key in that either CH1 settings are
applied to both channels or the CH2 settings are
applied to both channels.
The copy menu (copy key) allows to copy CH1
into CH2 parameters or vice versa in order to
have the same parameters in the two channels
to start with.
M/S Mode,
Sidechain Link
The DS1-MK3 can be switched to M/S (Mid /
Side) mode. To do that press the menu key, the
following menu opens up:
Graphic 22: M/S Mode and Sidechain Link
Key A selects M/S Mode on / off (box checked
means M/S mode engaged) while Key B selects
the sidechain link on / off (box checked means
sidechain linked). In M/S mode it usually is pref-
erable to set the channels unganged and the
sidechain unlinked.
Graphic 23 shows the block digram of the DS1-
MK3 when in M/S mode. Note the positions of
the M/S encoder and decoder. With the “Gain”
controls it is possible to change the balance be-
tween M and S, while the “Output Gain” controls
are arranged after the M/S to L/R conversion.
The “Compressor” block can again work in full
band mode or in band selective mode, inde-
pendently in the two channels. I.e. it is possible
to process e.g. the S signal in full band mode
and have the M signal processed in band selec-
tive mode for de-essing.
The parallel compression again works around the
“Compressor” block. Parallel compression can be
switched on independently in the two channels.
