BALANCE control
Should normally be left in the center position. Adjust balance if the
sound is louder from one of the speakers. If the right side is louder,
turn toward the L position and if the left side is louder, turn toward
the R position.
NOTE:
This control does not operate when DIRECT switch is in the on
position.
@ SUBSONIC filter switch/indicator (A-402 only)
Use this switch when playing records with coarse grooves.
On:
The indicator lights: In this position, frequencies of 17 Hz and below
are cut, eliminating super-low-frequency noise caused by coarse
record grooves, and thus helping prevent sound distortion.
Off:
The indicator goes off: Leave in this position for normal playback.
NOTE:
This switch does not operate when DIRECT switch is in the on
position.
@ DIRECT switch/indicator
Use this switch/indicator when you do not wish to pass the output
from input terminal equipment through the various frequency
adjusting circuits (BASS, TREBLE, SUBSONIC (A-402 only)) and
adaptor terminals (ADAPTOR).
On:
The indicator lights: The signals input through the input terminals
are reproduced without passing through the various frequency
adjusting circuits. This results in flat, pure sound which is a more
faithful reproduction of the input source.
Off:
The indicator goes off: The signal passes through the various
frequency adjusting circuits.
@ MUTING switch/indicator (A-402 only)
Use to temporarily cut sound volume.
On : The indicator lights.
The sound is cut off.
Off : The indicator goes off.
The sound will return to its previous volume.
