specification
The miniature condenser microphone system SMS 2000 consists of a microphone preamplifier and exchangeable capsules with the polar patterns cardioid, hypercardioid and omnidirectional. Accordingly, the microphones M 200, M 210 and M 270 are available. This allows universal applications in professional recording and sound reinforcement. The transformerless circuit design substitutes the previous transformer for a symmetrical output stage. The preamplifier is distinguished by its remarkably low intrinsic noise and output capabilities. The module system adjusted to optimum reproduction properties allows a particularly clean and colourless sound reproduction.
It is possible to activate a 10 dB preattenuation for handling very high sound pressure levels. A sensitivity reduction for low frequencies can be utilized to suppress the proximity effect. The two switches are sunk into the middle of the microphone.
