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:
1 Connect the L connector of an MS microphone to an odd channel input jack,
and the R connector to an even channel input jack.
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.
2 Use the DISPLAY ACCESS [PAIR] button to locate the Pair pages.
3 Turn on the MS button for the channels to which the MS microphone is con-
nected.
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
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.
