SOUND ADJUSTMENTS
Stereo balance
The feeling of direction and depth that stereophonic sound pro-
duces is greatly diminished if the levels of both channels are not
balanced.
Set
the
MODE
selector
to "MONO"
and
adjust
the
BALANCE control for equal output from the right and left speakers.
Balance variations with different program
sources
are due to dif-
ferences in the recording levels.
Stereo balance is also influenced
by the acoustics of the room.
Carpets, furniture placement, and
room size and shape have a definite effect upon sound quality and
balance.
Tone
Generally, the tone control circuits of an amplifier may somewhat
affect the tonal response in the amplifier signal chain.
To obtain
an absolutely flat frequency response, depress the DIRECT switch
to completely disconnect the tone control circuits from the signal
path.
(The LOW FILTER switch should also be set to OFF.)
How-
ever, if it is necessary to compensate for any deficiency in tone
quality due to the speaker system characteristics, listening room
acoustics,
or
improperly
equalized
program
source
material,
depress the TONE switch and adjust the tone with the TONE con-
trols.
To reduce
low frequency
noise such as the rumble created by a
turntable or warped records, use the LOW FILTER switch.
For detailed information about the controls and switches, refer to
the "FRONT
PANEL
FACILITIES" on page 10.
TAPE RECORDING
