Using MS Stereo Microphone 77 Using MS Stereo Microphone The MS system is a type of stereo recording that uses two microphones; mono-directional M (Middle) and bi-directional S (Side) microphones. An M microphone picks up main signals, and an S microphone picks up directional signals. These two signals are decoded by calculating a sum (M plus S) and a difference (M minus S), and are recorded to L and R channels. An MS microphone is usually a stereo microphone that has both M and S functions. Use an MS microphone in the following way: 1 Connect the R connector of an MS microphone to an odd channel input jack, and the L connector to an even channel input jack. Signals from the MS microphone are input from the L and R connectors. To MS microphone use an MS microphone with the 6 DM1000, connect the L connector to the input jack of an odd Input Chan- nel, and connect the R connector to the input jack of the partner channel.

The two channels are automatically paired and MS Decoding is turned on. With MS Decoding turned on, the faders and Encoders (Pan parameters) function as follows: • Odd-channel faders M level (Controls the volume level.) • Odd-channel Encoders ...........ML/MR balance • Even-channel faders S level (Controls the left and right directional spread.) • Even-channel Encoders ..........SL/SR balance 4 Use the faders and Encoders to adjust the MS microphone level and balance. When the signals are routed to paired Buses or the Stereo Bus, a sum of signals (ML plus SL) is sent to the odd-numbered Bus, and a difference of signals (ML minus SL) is sent to the even-numbered Bus.
