Description Type: Vintage Stereo Microphone Model: MC 833 Brand: Beyerdynamic Country/Region of Manufacture: Germany
BEYERDYNAMIC MC 833 STEREO MICROPHONE This 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.For MS stereo recordings the switch in the body of the microphone 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.
