Glossary

ATS

Automatic Tape Selection. The tape deck automatically sets the appropriate equalization characteristics and bias current according to the tape type inserted in the deck.

Automatic calibration

The automatic adjustment of the bias current and recording level for the inserted tape.

This adjustment works together with the deck’s ATS (Automatic Tape Selection, see above) to get the best possible recording results on any tape.

Dolby HX PRO system

Distortion and noise reduction system. The Dolby HX PRO system reduces distortion and noise in high-frequency response while recording. A tape recorded with this system brings the same high-quality sound even when you play the tape on the other tape decks.

Dolby NR (noise reduction) system

Noise reduction system for eliminating hissing noise. The Dolby NR system boosts the low-level signals in high frequency during recording and restores them during playback.

B and C Dolby systems are available on this tape deck. Of the two, C provides higher noise reduction than B.

Dolby		Noise reduction
dB NR off
Output		B
level	C
100	500 1k	5k 10k Hz

MPX filter

Multiplex filter. A filter for eliminating the 19-kHz stereo carrier and the 38-kHz sub-carrier signals that may impair the Dolby NR system. Usually the tuner has an MPX filter. If you cannot get a satisfying result when recording FM broadcasts with Dolby NR system, your tuner does not have a filter or the filter is not working. In this case, turn the DOLBY NR switch countercolckwise to the position you want — B or C with MPX FILTER.

Multi-AMS

Multi-Automatic Music Sensor is a function that locates the beginning of up to 30 tracks before or after the current track by detecting a blank space (of over 4 seconds) between tracks.

Tape counter

Afour-digit readout for monitoring elapsed playing or recording time. Useful for editing tapes. Press RESET to zero the counter (00 00).

Test tones

15-kHz, 3-kHz and 400-Hz signals produced by the tape deck when you do the automatic calibration.
