@ BNSS AND TREBLE coNTRoLS
Use these controls to adjust the bass and the treble. lf you
turn the bass control to the right from itscenter {0) posi-
tion, you will be able to emphasize the sound in the low-
frequency range. Conversely, turning this control to the
left from the center (0) position willattenuate the sound.
You can use the treble control to adiust the sound in the
high-trequency range.
@ LOW FILTER SWITCH
When this switch is set to
'lsHz.
a 6dB/oct attenuation
can be provided for frequencies below 15H2. This means
that you can cancel out noise in the ultra-low frequencies
which is generated by low-pitched rumble from a turn-
table and other forms of distortion. Although this noise
cannot be heard, it can generate intermodulation distor-
tion and damage the speakers.
@ rape MoNtroR swrrcHEs
Employ for tape playback or to monitor a recording in
progress.
1: Playback or monitoring of a tape deck connected to
the TAPE 1 jacks.
2: Playback or monitoring of a tape deck connected to

@ enlnNce coNTRoL
Use this control to balance the volume of the left and
right channels. First, however, set the mode/FM muting
switch to MONO/OFF. lf the sound appears to be louder
on the right, it means that the volume ot the right channel
is higher. Turn the balance control to the left and adiust.
Conversely, if the sound appears to be louder on the leJt,
it means that the volume of the left channel is higher.
Therefore, turn the balance control to the right and
adjust. After adjusting. return the mode/Fl\4 muting
switch to STE REO/ON.
@ MODE/FM MUTING SWITCH
This switch is a combination of the F l\il muting switch and
the mode select switch. When setting this switch at
STEREO/ON position the reproduction is jn stereo mode,
while the F l\il muting function acts to suppress unpleasant
interstation noise while tuning between FM stations when
listening to FM broadcasting. When setting this switch at
MONO/OFF position, however, reproduction is in mono
mode. while the FM muting function does not act, thus
enabling suitable reception of weak radio stations when
tuning in to the FM broadcasting station.
NOTE:
Recoding stercophonically with the mode/FM muting swiach in
the MONO/OFF position may cause deteriorction in channel se-
@ LOUDNESS SWITCH
When listening to a perlormance with the volume con-
trol turned down, depress this switch and the bass will be
accentuated.
When the volume is low, the human ear finds it harder to
hear the bass than when the volume is high. The loudness
switch is thus designed to compensate for this deliciency.
By depressing this switch, the bass come through much
more strongly and the sound takes on a punch even when
the volume control is turned down,
@ VOLUME CONTROL
Use this control to adjust the output level to the speakers
and headphones. Turn it clockwise to increase the out-
put level. No sound will be heard if you set it to "0."
