and treble response characteristics.

The DEFEAT position produces flat response.
B SUBSONIC FILTER switch
Used to cut out undesirable ultra-low-frequency signals caused
by turntable rumble or warped records without losing sound
quality.
C MODE switch
This switch can be used for switching between stereo and
monaural operation. Normally this switch should be set to the
STEREO position.
D BALANCE control
Adjusts the balance of the output volume to the left and right
speakers to compensate for sound imbalance caused by
speaker location or listening room conditions.

high and low-frequency ranges at low volume.
F REC OUT selector
This switch can be used to select a program source and supply
that source directly to the REC OUT terminals on the rear panel,
independently of the setting of the INPUT selector. This function
allows you to record the selected program source while listening
to another program source.
G PHONO (MM/MC) switch
This switch can be used to select either the MM (moving
magnet) or MC (moving coil) position to match the phono
cartridge used. (Refer to page 12 for details.)
