FET input PB amplifier
The FET input PB amplifier is a circuit that is positioned
between the playing head and the operational amplifier.
Unlike conventional amplifier circuits, which require a low
noise, medium-quality operational amplifier because of its
direct link with the playing head, the noise-free signal that
the FET input PB amplifier provides enables the use of a
higher quality operating amplifier, and more natural
sounding output.
Recording level calibration
Adjustment for optimum recording. Even when you have
adjusted the recording level correctly, the playing level
might turn out to be low depending on the tape used. By
adjusting the recording level calibration, you can
compensate for the low recording level. When you record
on a tape with the Dolby NR system, this function works
more effectively.

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, C, or S with MPX FILTER).
Multi-AMS
Multi-Automatic Music Sensor is a function that locates the
beginning of 30 tracks before or after the current track by
detecting a blank space (of over 4 seconds) between tracks.

Tape counter
A display element that shows the elapsed recording or
playing time as a digital readout. Since the counter is not a
digital clock, the displayed value will differ slightly from the
actual elapsed recording or playing time. The counter value
also includes the length of the leader tape.
Test tones
15-kHz, 3-kHz and 400-Hz signals produced by the tape
deck when you do the bias and recording level calibration.
