@ TREBLE tone control
Use for adjusting the high-frequency tone.
The central '0' position is the flat (normal) position.
When moved to the right, high-frequency tones are
emphasized; when moved to the left, high-frequency
tones are deemphasized.
BASS tone control
Use to adjust the low-frequency tone. The central
"0" position is the flat (normal) position. When mov-
ed to the right, low-frequency
tones are empha-
sized; when moved to the left, low-frequency
tones are deemphasized.
@) MIC MIXING control
Use to adjust the sound balance between the
microphone connected to the MIC jack, and com-
ponents (tuner, tape deck, turntable, CD player,
etc.) connected to the rear panel.
When the control is moved to the MIC side, the
sound from the microphone will be at a maximum,
while the sound from the other components will not
be heard.
When moved to the SOURCE side, the sound from
components will be at a maximum, and the micro-
phone sound will not be heard.
NOTE:
When performing playback of source components only,
leave the control set to the SOURCE side.
BALANCE switches
Normally, set so that the control display's BALANCE
function indicates at the center position. (When L
and R are pressed simultaneously, the balance will be
adjusted to the center position.) If the sound heard
from the speakers appears to be too loud on one
side, adjust as follows: If the right side is too loud,
press L. If the left side is too loud, press R.
(1) LOUDNESS switch
Press when listening at a low volume level.
When pressed ON, the control display's LOUDNESS
indicator will light. Very low- and very high-
frequency sounds will be augmented, thus giving a
more powerful sound quality even at low listening
levels.
(2) MUTING switch
Use to temporarily cut sound volume.
When pressed ON, the control display's MUTING in-
dicator will light, and sound volume will be cut by 20
dB. When set to OFF, the sound will return to its
previous volume.
When the power to the unit is turned OFF, a built-
in microcomputer automatically memorizes the
positions of the following switches, and will main-
tain that memory for approximately 1 week when
the unit is not used. As a result, when the power is
turned ON, the previously set switch positions will
be set again automatically.

If the unit is not used for more than one week, the
memorized positions will be cancelled, and the
following positions will be set:
e VOLUME switch — Minimum
e LOUDNESS switch, MUTING switch — OFF
e BALANCE switches — Center
