Using the 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 sig-
nals, 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 features both M and S functions. 
To use an MS microphone, do the following:

Signals from the MS microphone are 
input from the L and R connectors. To 
use an MS microphone with the 
DM2000, 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 Decod-
ing 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

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.
