11. Balance control (BALANCE)
This control allows the listener to adjust the relative volume
level of the left and right channels.
Rotating the control counterclockwise gradually cuts the
volume of the right channel, rotating the control clockwise
gradually cuts the volume of the left channel.
Under normal conditions, this control should be set to the
center position and then adjusted as necessary.
When the line straight switch is set to on, this switch does
not function.
12. Tone control for treble
TONE CONTROL (TREBLE)
Controls the frequency characteristics of the high-frequen-
cy range.
When this control is set to the center position, flat frequency
characteristic is obtained. Rotating this control clockwise
makes the high-frequency range enhanced, and rotating
this control counterclockwise makes the high-frequency
range attenuated.
When the line straight switch is set to on, this switch does
not function.
