(2) Remote control sensor window
(3) ADPT (adaptor)/TAPE 3 button/indicator
Use this button to listen to tape playback, or to monitor a tape
recording.
On: (Red illumination)
The indicator lights: Press when listening to the playback sound
of the cassette deck or the adaptor connected to the ADPT/
TAPE 3 IN/PLAY jacks, or to monitor the sound recorded on the
cassette deck connected to the ADPT/TAPE 3 OUT/REC jacks.
Off:
The indicator goes off: Normally leave the button in this position.
NOTE:
When the DIRECT
button is set to on, this function does not operate
and no signal is output at the ADPT/TAPE 3 OUT/REC jacks.
When the DIRECT
button is in the off position, only the source sig-
nal is output from the ADPT/TAPE 3 OUT/REC jack.
@ SUBSONIC filter button/indicator
Use this button, when playing records with coarse grooves.
On: (Red illumination)
The indicator lights: In this position, frequencies of 17 Hz and
below are cut, eliminating super-low frequency noise caused by
coarse record grooves and thus helping prevent sound distor-
tion.
Off:
The indicator goes off: Leave in this position for normal playback.
NOTE:
This button does not operate when the DIRECT button is in the on
position. This button operates when PHONO is selected by the IN-
PUT SELECTOR switch (refer to 9 on page 34).
G) LOUDNESS button/indicator
Use when listening at low volume level.
On: (Red illumination)
The indicator lights: Boosts low and high frequencies to give
added punch to playback even at low volume level.
Off:
The indicator goes off: Should normally be left in this position.
NOTE:
* This button does not operate when the DIRECT
button is in the on
position.
° At volume levels below the 10 o'clock position, the LOUDNESS
effect is obtained.
® At volume levels above the 10 o'clock position,
the effect be-
comes increasingly weaker.
© DIRECT button/indicator
Use this button when you wish to bypass the various frequency
adjusting circuits and adaptor jacks (ADPT/TAPE 3, SUBSONIC,
BASS, TREBLE, BALANCE, LOUDNESS).
On: (Orange illumination)
When this button is in this position, the indicator lights and the
signals input from the input jacks are reproduced without pass-
ing through the various frequency-adjusting circuits. This results
in flat, pure sound which is a more faithful reproduction of the
input source.
Off:
When the button is in this position the indicator goes out and the
signal passes through the various frequency adjusting circuits.
