Description
The DBX 122 and 124 are the only consumer tape noise reduction systems available which allow you to make tape copies that sound exactly the same as the original is the DBX II. It assures that no audible tape noise is added by the tape recording process. Only noise present in the original source will survive the DBX II system.

The 122 is a two-channel system which 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 10 dB of high frequency noise reduction, vs an astounding 30 dB 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.
