“Double M/S“ Surround with Double MS Set
– requires only three microphones and channels for
5.0 surround
– very small, lightweight array
– can be well protected against wind (with “fur”
Windjammer)
– matrixing can be performed during or after recording
”Double M/S” is an improved version of the well-known
M/S stereo recording technique. In addition to a front-
facing cardioid or supercardioid ”mid” microphone
and a figure-8 ”side” microphone, a rear-facing direc-
tional microphone is set up (see illustration at right).
The front- and rear-facing microphones share the sig-
nal of the figure-8 microphone so as to form two
complete, back-to-back M/S systems. One M/S system
then provides the three front channels (the center
channel signal being provided directly by the mid
microphone of the front system), while the other sys-
tem provides the two surround channels. An arrange-
ment of this kind allows flexible processing of the
stereo surround image width and post-production
adjustment for both of the M/S pairs.
The microphones and accessories for Double M/S
recording are available in three different sets:
1. Double M/S Set with Splitter
– 2 × CCM 4VL cardioid compact microphones (or a
CCM 41VL supercardioid can be substituted for the
forward-facing cardioid at a small increase in price)

– special shock mount for the three compact micro-
phones
– adapter cable from three Lemo plugs to one XLR-7
output
– WSR DMS LU basket-type windscreen
– WJ DMS ”Windjammer” windscreen cover
– KDMS 5U 5-meter (16.5') XLR-7 extension cable

2. Double M/S Set with M DMS
