CONTROLS
TELE
@ POWER ON/OFF Button
This button turns the power on and off.
@ Headphones Jack
For connection of stereo headphones.
© POWER ON Indicator
This indicator lights up to indicate that the power is on.
© SPEAKERS Selector Buttons
These buttons are used to select operation of two sets of speakers.
That is, speaker set A, B, or A+B may be operated, or all speakers
may be disabled when headphones are used.
@ Tone Controls
The tone controls are provided for boosting or cutting the volume
of low and high frequencies. This is especially useful as the sound
from the speakers can be compensated to reproduce all frequencies
equally. Also, since listening areas vary for each use, the tone
controls may compensate for various deficiencies in the listening
room.
BASS: Controls the level of the low frequencies.
TREBLE: Controls the level of the high frequencies.
These controls give a flat response when in the center position.
Slide them to the right to increase the respective levels, and to
the left to decrease them.

@ BALANCE Control
The balance between left and right channel volume levels can
be adjusted using this control. Use the control to correct the
balance between the left and right speakers, e.g. due to the fur-
niture arrangement in the listening area. Also, some program
sources have poor balance between left and right channels. In
such a case, the BALANCE control can be used to provide proper
compensation for equal volume level between left and right
channels. When the control is slid to the left, the right channel
volume decreases, and vice versa. This unit has been factory
adjusted so that proper balance can be obtained when the balance
control is set in the center defeat position.
@ SUBSONIC FILTER Button
Press this button to eliminate low frequency noises such as the
rumble caused by the turntable’s motor or warped records.
