USING THE SENNHEISER MKH 418S
STEREO MICROPHONE
The Sennheiser MKH 418S is a stereo version of the MHK 416. It is an M-S (Mid - Side) stereo mi-
crophone. It is actually two microphones in one housing -- a directional mic (mid) picking up sounds
from the front and a bi-directional mic (side) picking up sounds from the left and right sides.
The output of the 418S is two signals -- the Mid and the Side. As such they are NOT normal Left -
Right stereo, but can be turned into L-R stereo with a special “matrix” circuit. The 418S is intended
to be used with the Sound Devices hard disk recorders (722 and 744T) which have the M-S matrix
circuit built in.
No other Cage equipment has this circuit
.
There are times and situations to record in stereo, and times and situations NOT to record in stereo.
These are detailed on pages 2 and 3. On pages 4 and 5 are instructions about menu settings for the
Sound Devices recorders for the different applications.
