14. Balance (BALANCE)
Adjusts the balance of sound volume between right and left
channels.
Rotating this switch counterclockwise causes the left sound
volume to be enhanced, and rotating the switch clockwise
causes the right sound volume to be enhanced.
This switch shall be set to the center position under normal
conditions and rotated to make adjustment if necessary.
When the line straight switch is set to on, this switch does
not function.
15. Tone control for treble
(TONE CONTROL, treble)
Controls to change the frequency characteristics in the
high�frequency range.
When this switch is set to the center position, flat frequency
characteristic is obtained. Rotating the switch clockwise
causes the high�frequency range to be enhanced, and rotat�
ing the switch counterclockwise causes the high�frequency
range to be attenuated.
When the line straight switch is set to on, this switch does
not function.
16. Tone control for bass
(TONE CONTROL, bass)
Controls the frequency characteristics in the low�frequency
range.
When this switch is set to the center position, flat frequency
characteristic is obtained. Rotating the switch clockwise
causes the low�frequency range to be enhanced, and rotat�
ing the switch counterclockwise causes the low�frequency
range to be attenuated.
When the line straight switch is set to on, this switch does
not function.

Selects the B system speaker terminal.
A+B:
Simultaneously activates both A and B system
speakers. When both speaker terminals are si�
multaneously used, select speakers with imped�
ance of 8 ohms or more because both output
terminals are connected in parallel.
19. Recording selector (REC SELECTOR)
Selects an input source to be recorded and sends record�
ing signals to the recorder connected to this unit.
When both of the input selector (INPUT SELECTOR) and
the recording selector (REC SELECTOR) are set to the line-
2 position, the LINE-2 unbalance/balance selector(bal.line-
1) toggles the recorder output terminals on the rear be-
tween the unbalance input terminal (LINE-2) and balance
input terminal (BALANCED LINE-1).
When you need not toggle an input source to be recorded
(especially when a recorder connected to the recorder out-
put terminals is recording), do not operate this switch.
20. Headphone jack (phones)
Is used to listen to sound with use of stereo headphones.
Insert the headphone plug into this output jack. Even when
the plug is inserted, signals to the speaker output terminal
are not interrupted. Accordingly, to listen to sound with only
