Schoeps CMH-641U
12V or 48V Phantom Super Cardioid Hand Held

CMH-641U

The CMH 641 U hand held microphone with super cardioid pattern offers a very effective windscreen into which a special capsule is integrated. It can operate with any 12 V or 48 V standard phantom powering. The increased directionality and the reduced low-frequency response of this model help to reduce the chance of acoustic feedback when used with monitor loudspeakers or a public address system – provided that the microphone is aimed at the soloist and not at the loudspeaker system.

Protection from plosive sounds (vocal popping) can be achieved with conventional windscreens; but the more effective these are, the greater the risk to the other parameters of the microphones’ performance. Protection from solid-borne noise is achieved by means of a progressively elastic mounting for all the functional elements.

When there is simultaneous loudspeaker transmission, the risk of acoustic feedback is reduced by the low-frequency rolloff and the directional characteristic, provided that the performer stays on axis and away from the loudspeakers. Proximity effect may be used to boost the voice of the speaker or singer.
