range of settings will depend on the
type of microphone used for the M
channel; the broader its directional
pattern, the farther the "WIDTH" con-
trol can be turned up. This control also
affects the recording angle – the widest
arc, as viewed from the microphones'
position, which may be picked up
without creating ambiguity as to the
location of sound sources. In general,
the greater the directionality of the M-
channel microphone, the narrower the
recording angle will be (see the dia-
grams on the opposite page).
The farther the "WIDTH" control is
turned up, the greater will be the angle
between the "virtual microphones." The
recording angle, on the other hand,
will become narrower. Any sound
sources located beyond that angle
(near the edges) will be picked up out
of phase, and will seem to jump over
to the channel opposite from where
they were in reality.
The optimal WIDTH control setting
depends on the directional pattern of
the microphone being used for the M
channel, the relative sensitivity of the
two microphones, and the recording
environment. Setting "4" would be a
suggested starting point.
In M/S recording, the WIDTH control
and the balance setting both control
the relationship of M to S, thus affect-
ing the stereo image width and the
recording angle as well. When using
One possible way to set up an M/S
