MC 833 Stereo Condenser Microphone
Applications
The MC 833 is suitable for studio applications, live
recordings and miking of choirs.
Connection
The MC 833 is equipped with a 7-pin XLR plug. You
can connect it to any microphone input supplying phantom
power between 12 and 48 V.
Setting up and Use
The MC 833 offers without an additional matrix:
1. True MS-recording
2. True XY-recording
3. Mono recording
The microphone is equipped with three true condenser systems
(no electret). The polar pattern of each cartridge is cardioid and
almost independent of the frequency.
The middle system supplies the mono-signal or the M-signal with
MS stereophony. The system located to the left and right of the
middle system are switched together to form a figure-of-eight
polar pattern and supply the S-signal. At XY stereophony only
the two side system are used. They can be mechanically adjusted.
Therefore, at XY recording the recording angle can be continuously
varied over a large range.
MS Stereo Recording
For MS stereo recordings the switch in the body of the micro-
phone has to be in position MS. The M-signal is recorded by the
middle system. The two external systems are mechanically
adjusted to 180° and supply the S-signal with a figure-of-eight
characteristics which is transverse to the microphone axis.
By selecting a different angle than 180°, the amount of the
S-signal can be reduced, but the optimum signal-to-noise ratio
is obtained at 180°. Therefore, if the recording angle shall be
changed by varying the share of the S-signal, the best results are
obtained by using an external matrix amplifier. For MS-stereo
recording with the MC 833, however, a matrix amplifier is not
necessary, as the microphone supplies already a MS signal.
Pin configuration of the microphone plug for MS-
stereophony:
M (mid channel, yellow): pin 1 (ground), 4 (+), 5 (-)
S (side channel, red): pin 1 (ground), 2 (+), 3 (-)
Two microphone inputs with 12 to 48 V phantom power are
necessary.
XY Stereo Recording
For XY stereo recording the switch has to be adjusted to XY.
The two side systems are used (cardioid polar pattern). The
angle of both systems relevant to each other can be mechanically
adjusted from 60° (± 30° against axis) to 180°. The range of 60°
to 140° is marked red and shows the preferred recording angle
(acc. to Williams).
A matrix amplifier is also not required for XY stereo recording as
the microphone supplies an XY signal.
Pin configuration of the microphone plug for XY-
stereophony:
R (right channel, red): pin 1 (ground), 4 (+), 5 (-)
L (left channel, yellow): pin 1 (ground), 2 (+), 3 (-)
Two microphone inputs with 12 to 48 V phantom power are
necessary.
Mono Recording
Mono recording can be derived from the MS or XY signal.
Switch position to MS:
The M signal is a true mono signal. The polar pattern of the
microphone is cardioid in this case. The yellow marked plug of
the split case is used (or a mono-cable connected to pin 1, 4
and 5 of the microphone plug).
One microphone input with phantom power of 12 to 48 V is
necessary.
In special cases like dialogues between two persons, it is
recommended to use the S-signal. Here the polar pattern is a
figure-of-eight.
Switch position to XY:
A mono signal can be produced out of the XY signal by inter-
connecting both channels. By means of a relevant mechanical
adjustment of the angle of both systems against each other,
the polar pattern can be varied from broad cardioid up to
omnidirectional.
