Switch ‘s’ (side)
Left = Normal phase (no decode).
Right = Reverse phase (M/S decode).
Use an odd numbered channel for the mid mic (cardioid/omni) & an even numbered channel for the side mic (figure of
eight). With both pan pots centered & equal gain for both channels, the M/S mic will be decoded to L/R stereo at 50%.
Mid = L + R (channel 1) (bus A + B or C + D)
Side = L - R (channel 2) ( bus A - B or C - D)
Any number of ‘even’ channels may be set up for this option.
Also see stereo channel CSST-208 for a dedicated 1 channel M/S decoder.
