SA-708
@) BASS AND TREBLE CONTROLS (@ FUNCTION SELECTOR
Use these controls to adjust the bass and the
treble. If you set the tone switch to ON and turn
the bass control to right from its center position,
you will be able to emphasize the sound in the
low-frequency range, Conversely, turning the bass
control to the left from the center position, you
will attenuate the sound.
You can use the treble control to adjust the
sound in the high-frequency range.
TONE SWITCH
Set this switch to ON when adjusting the bass and
treble controls. When set to OFF, the tone con-
trol circuits are disengaged and frequency
response is flat. This function is convenient for
checking phono cartridge and speaker tone
quality and listening room acoustics.
d@) BALANCE CONTROL
Use this control to balance the volume of the left
and right channels. First, however, set the mode
selector to MONO, and adjust so that the sound
appears to come from somewhere exactly be-
tween the two speakers. If the sound appears to
be louder on the right, it means that the volume
of the right channel is higher. Turn the balance
control to the left and adjust.
Conversely, if the sound appears to be louder on
the left, 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 selector to ST.
42 SUBSONIC FILTER SWITCH
When this switch is set to the 15Hz position, the
subsonic filter with a cut-off frequency of 15Hz is
actuated. The subsonic filter serves to attenuate
frequencies lower than 15Hz in a 6dB/oct slope.
It is therefore effective in suppressing ultra-low-
frequency noise which is generated by record
warp and other causes. You cannot actually hear
this noise but it is a factor in the generation of
intermodulation distortion and it may damage
your speaker system. Set this switch to the 15Hz
position during record play for the best effect.
