Balancing Your Stereo

The performance and enjoyment of a stereo system is

greatly increased when the sound is properly balanced.
The balance of the stereo system is affected by many things

including room acoustics, furniture placement, room shape,

small differences in loudspeakers, etc. To assist you in

balancing your stereo system in your room, here is the
procedure to determine correct phase and program loudness.

TO ADJUST PHASE

1. Play a familiar record.

2. Press the MODE pushbutton to the MONO position.

3. Turn BALANCE control to 12 o'clock position.

4. Stand about 10 feet in front of and midway between the

loudspeakers. The sound should appear to come from

directly in front of you. If the sound is not directly in
front of you with the phase switch in the 0° NORMAL

position, reverse the leads on one loudspeaker. When

the sound comes from directly in front of you the
speakers are in PHASE. Use the PHASE switch to correct

for out of phase program sources.

TO BALANCE LOUDNESS

1. Press the MODE pushbutton to the MONO position.

2. Play a familiar recording,

3. Turn the BALANCE control to the 12 o'clock position.

4. While the program is playing, stand between the two

loudspeakers. Listen for a difference in loudness be-

tween speakers. Balance the system by adjusting the

controls on the power amplifiers. Next, set the MODE

selector to STEREO. If there is then a difference in loud-

ness turn the BALANCE control toward the speaker that
is not as loud. Adjust the BALANCE control until the

sound is satisfactory between both speakers.
