Description
The SC-1 sound calibrator is a single-frequency dual-amplitude, self-contained field calibrator used to quickly and precisely verify the accuracy and the sensitivity of microphones. The unit generates a 1kHz reference tone at 94 and 110 dB SPL. The SC-1 consists of an amplitude-switchable constant frequency oscillator, a transducer and a microphone coupler. The coupler accepts a large variety of microphones.
