STEREO INPUT CHANNEL

Any pair of mono channels can be converted to stereo pairs.*
The cosmetic difference is that the Pan out switches are 
replaced with Link & MS Decode switches with  LEDs above.

1. Link:

Both channels (odd & even) are linked together with one 
stereo fader on the odd channel - the even channel fader is

disconnected from the circuit.  ‘Link on’ also links the two
limiters.

2. MS DEC:

MS Decode - The even channel output is inverted to bus B
only.  Both pan pots should be centered.  With equal gain,

the M/S mic configuration is decoded to 50%.

Odd channel = mid, Even channel = side.

The result will be:
A bus = M + S = L,  B bus = M - S = R
The stereo image width can be changed by altering the gain
of one channel.

Note:  A & B assign switches should be on for both channels.

C & D busses are now pre pan pot (& inverter), allowing a non decoded MS

mic configuration to be recorded, pre or post fader to C & D busses.

MS mic configuration can also be recorded via the pre fader channel outs.

Note: For decoding MS to the monitor only - see output section.

*A retrofit kit is available.
