MONITOR BUTTON _
This Stereo cassette deck uses a three-head system which permits simultaneous "off-the-tape monitoring" during
recording. Use the MONITOR button to select monitoring sources. Incidentally, as this Stereo Cassette Deck adopts an
automonitor system, ITAPE! or! SOURCE!can automatically be activated according to the operation conditions. These modes
can also be activated manually~ The MONITOR indicator shows the selected monitoring source, ITAPE! or! SOURCE!

The signal recorded on the tape is monitored simultaneously
"off-the-tape". This monitoring mode enables you easy
check for optimum recording levels. In the
I TAPE I mode,
the FL PEAK METER indicates the signal levels played back
off-the-tape.
The SOURCE position enables you to monitor -the input
source signal before it is recorded on the tape. Using the
FL PEAK METER, this mode is convenient for setting
recording levels or input level monitoring during recording.

the signal from the tape won't be heard.
DOLBY C NOISE REDUCTION SYSTEM _
• The Dolby noise reduction system substantially reduces
the tape background noise (hiss) inherent in the cassette
medium. Dolby B NR is most widely in use. However,
Dolby C NR is a much more recent development and
represents a significantly improvements over Dolby B NR.
• Tape background noise consists primarily of high frequency
information which is particularly annoying during soft
passages. The Dolby NR system increase the level of
low volume mid and high frequency signal during recording
and reduces the level of these signals by an identical
amount during playback. As a result, the playback signal
is identical to the original source signal, but the level
of background noise generated by the tape is greatly
reduced.
• The operating principle of Dolby C NR is simi lar to that
of B except for the encoding/decoding response curves.
The noise reduction effect obtained by Dolby C NR is up
to 20dB, compared to lOdB with Dolby B NR. In addition,
Dolby C NR uses an antisaturation network and spectral
skewing circurity, and significantly improves the dynamic
range in the mi.d to high frequencies.
DOLBY HX-PRO HEADROOM EXTENSION SYSTEM _
This deck is equipped with the DOLBY HX-PRO headroom
extension system. Since the system functions automatically
during recording, no switching operation or adjustment is
required. The system is effective with any type of Normal,
CrO, or Metal tapes.
The Dolby HX·PRO headroom extension system functions
during recording to lift up the saturation level in the treble
range. Therefore, most of the treble range components
distorted or lost during recording on conventional cassette
decks are more faithfully recorded on the new DRM-800A
cassette deck.
Features of the DOLBY HX-PRO headroom extension
system
( 1) Performance of Normal and CrO, tapes can be up-
graded closer to that of Metal tapes.
(2) The dynamic range in the treble is improved signifi-
cantly.
(3) Since no decoding in playback is necessary, the
improvement can be obviously heard on any hi·fi
playback system including portable components and
car systems.
(4) The system functions whether the Dolby B/C NR is
engaged or not.
