by comparing it with the input source signal.
To listen to the input source signal, press the MONITOR
button to turn on the SOURCE indicator.
To listen to the sound recorded on the tape, press the
MONITOR button to turn on the TAPE indicator.

What Is the Dolby HX PRO System?

The Dolby HX PRO system provides precise bias control
during recording to reduce distortion and improve linearity
in the high-frequency range. The result is recorded sound
that is highly faithful to the original. Since the HX PRO
system operates only during recording, the same high-
quality sound is produced even during playback on other
tape decks. The HX PRO system is independent from the
Dolby NR system and is unaffected by the Dolby NR setting.
