Record azimuth correction. To ensure the best response from the wide variety of tapes available adjustment of, bias, equalization and sensitivity, to optimum levels can be performed prior to recording.

The Dolby-B system reduces tape hiss on tapes recorded on the 700ZXL by as much as 10 dB at the highest frequencies. The three-head configuration of the 700ZXL requires a Double Dolby system, one for recording and one for playback. A Subsonic filter is provided in the 700ZXL to prevent infrasonic signals generated when playing a warped record. These signals can upset the Dolby system and prevening it from functioning properly. The 19kHz multiplex pilot slgnal present in FM stereo broadcasts can cause false triggering of the noise reduction system. The switchable MPX filter of the 700ZXL filters out the pilot signal, and assuring proper Dolby processing of FM stereo programs.

For undisturbed listening a jack connector for a pair of stereo headphones is supplied. Connection to other audio components for plaback can be achieved by a RCA cable and recording from a source by a RCA cable.
