DBX 124


The DBX 124 a four-channel version of the 122 noise reduction system. If used for stereo, it allows you to simultaneously monitor the noise-reduced signal off tape as you record. You can use both to record live, tape to tape, record to tape, and also for dubbing and taping off radio.

Complex level matching and alignment procedures are unnecessary, since these systems operate linearly, using the DBX patented true RMS detectors and voltage controlled amplifiers.

This is not the case with competitive systems, such as Dolby's B. Moreover, Dolby B gives you only 7 to 10dB of high frequency noise reduction versus an astounding 30dB reduction of tape background noise at all frequencies with the DBX II system.

Other features include a bypass switch, power on/off plus a DBX disc playback button. The latter is to be used only to decode commercially available DBX encoded discs, which provide totally noise-free, full dynamic range music reproduction. A playback level control is provided for your convenience.
