balance between the main information of the mid

channel and the spatial contribution of the side

channel. This balancing can even be performed during

re-processing without a loss of information if the

original MS signals were recorded.

The MS signal format is converted into the XY format

(ie: standard left/right stereo) by adding or subtracting

the signals according to the principle X = M + S,

Y = M – S. The proportion of the S signal influences

the spatial effect and should be chosen in each case in

accordance with the recording situation. In order to

avoid restricting the possibilities of designing the

sound impression, MS – XY matrixing in the

microphone was not employed.

If a matrix circuit is not available on the mixing

console, matrixing can be performed using the 3-fader

method (see diagram). The M signal is connected to

the first microphone channel and panned centre. The

S signal is connected to the second channel and

panned full left. Take an output from the second

channel and connect to the third channel panned full

right and phase reversed (via a phase reverse switch

or via the cable). (To set the correct S signal level - set

the pan controls of channel two to central, set the main

fader to normal level and set the correct level at the

preset. Then, set the pan control of channel 3 to

centre, set the main fader to the same level as channel

two and then adjust the pre-set of channel three until

3dB
