Dolby Laboratories Model 363 2Ch SR/A-Type Processor Noise Reduction,Spectral Recording,# 300 Module
Dolby®noise reduction is a family of signal processes that reduce the noise inherent in analog recording media, without affecting the sound quality of the recorded audio. Dolby SR improves the dynamic range of analog recordings and transmissions by as much as 24 dB, providing the performance typically associated with digital recording formats while maintaining the desirable features of analog recording. It essentially eliminates tape hiss, modulation noise, print-through, and crosstalk, increases low- and high-frequency headroom, and decreases distortion. Dolby A-type is the original professional system, providing 10 dB overall of noise reduction. The 363 provides Dolby SR and Dolby A-type noise reduction for all audio facilities: music recording, postproduction, broadcast, multimedia, and film. Record/playback changeover of each channel can be controlledindividually from the front panel, or automatically from a tape recorder, so that a single 363 can serve as both an encoder and decoder for stereo recording applications. A setup button and four-element LED calibration displays allow quick alignment using an internally generated Dolby tone for A-type or Dolby noise for SR. The 363 is also ideal for applications requiring dedicated encode or decode operation. A pair of 363 units can be used for simultaneous record and playback on two-channel tape recorders, or for transmission systems where the encoder and decoder are physically separated. In single-channel recordingapplications, a single unit can be used for simultaneous record and playback. The 363 is normally supplied withtwo Cat. No. 300 modules, which contain both Dolby SR and Dolby A-type processing. A version incorporating Dolby SR only (using Cat. No. 350 modules) is also available.   Will ship worldwide have a number of units available.
