Names and Functions

10. Tone control for treble

TONE CONTROL (TREBLE)

Controls the frequency characteristics in the high-frequency
range.
When this control is set to the center position, flat frequency
characteristic is obtained. Rotating this control clockwise
causes the high-frequency range to be enhanced, and ro-
tating this control counterclockwise causes the high-fre-
quency range to be attenuated.
This control does not function when the line straight switch
is set to ON.

11. Tone control for bass

TONE CONTROL (BASS)

Controls the frequency characteristics in the low-frequency
range.
When this control is set to the center position, flat frequency
characteristic is obtained. Rotating this control clockwise
causes the low-frequency range to be enhanced, and rotat-
ing this control counterclockwise causes the low-frequency
range to be attenuated.
This control does not function when the line straight switch
is set to ON.

12. Line straight switch (LINE STRAIGHT)

This switch is used to increase the purity of the sound qual-
ity by bypassing (skipping) the tone control circuit.
Every time this switch is pressed, line straight setting tog-
gles between ON and OFF repeatedly.
The line straight indicator lights up when the line straight
switch is set to ON.

When the line straight switch is set to ON, the tone control
and loudness do not function.
