– requires only three
microphones and channels for 5.0 surround
– very small, lightweight array
–
can be well protected against wind (with “fur” Windjammer)
– allows post-production processing (if matrixing takes
place after the recording)
"Double M/S" is
an improved version of the well-known M/S stereo recording technique. In
addition to a frontfacing
cardioid or supercardioid "mid" microphone and a
figure-8 "side" microphone, a rear-facing directional microphone
is set up. The front- and rear-facing microphones
share the signals 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 system provides the two
surround channels. A double M/S arrangement of this kind
allows flexible processing of the stereo surround image
width and post-production adjustment, just as with two channel
M/S recording.
The Double-MS Set consists of a special shock mount
with three CCM-L miniature microphones in a double M/S
configuration, a windscreen and a Windjammer. (Instead of
the CCM 4VL, a CCM 41VL supercardioid can be ordered.)
A cable adapter from three Lemo sockets to an XLR-7
output connector is included as well as an XLR-7 extension
cable (5m long) and a DMS-Splitter. The latter is a passive
device that simplifies connecting a double M/S array to
phantom-powered preamplifiers with matrix circuitry (e.g.
2* Schoeps VMS 5U) or to the inputs of a mixer. It divides
the signals from the three microphones to five outputs
(the center channel plus the two M/S pairs, with two of
the microphones serving dual functions), while preventing
any overlap in the phantom powering of the microphones
from the inputs to which it is connected
