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

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.

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.

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.
There are 4 types in the Dolby NR system:  A, B, C and S.
A-type is for professional use (not available on this tape
deck), and B, C and S-types are for consumer use.  S-type has
the maximum noise reduction capability, followed by C and
B.

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, C, or S with MPX FILTER.

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.

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

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