4.3.8 Linking channels 1 & 2 [ - / LINK / MS]
Channel's Fader 1 can be linked with channel's Fader 2 by means of this switch, thus only one fader nr 2 controls
both input channels which ensure to keep the same mixing level on these 2 channels. This is useful to keep the
balance of a stereo microphone, an M/S pair or any other stereo source.
When channel 1 is linked to channel2, only the fader nr 2 is active.
Upper position: no linking, both channels are independent.
Position LINK:
channel's fader 1 is linked to channel's fader 2, only fader 2 is active
Position MS: same as LINK, but decodes the M/S signal sent to the mix bus.
The channel 1 is the M signal; the channel 2 is the S signal
Decoding M/S
While decoding an MS modulation, the M channel is routed to both Left and Right outputs through the mix busses;
the S channel is sent in phase to the Left output and phase reversed to the Right output
The M channel must be connected to input [IN1]
The S channel must be connected to input [IN2]
When MS is selected, the panning switches L-C-R of channels 1 & 2 are automatically deactivated and have no
longer any influence on the routing.
As mentioned above, both fader 1 & 2 are linked, but not the [ GAIN ] potentiometers. So you can still vary the
input gain which allows you to change the stereo image (spread). When both input channels have the same gain,
then the M/S decoding ration is 50/50. If the gain of the S channel is reduced, then the stereo image is narrowing
(more centred), and conversely if the gain of the S channel is increased, the stereo is widening.
