ENHANCED STEREO
This position should be used to enhance (convert) any stereo source into
spatially expanded sound. When playing any stereo source, if your 75+ has
been installed utilizing four or eight speakers, the sound will emerge from
each speaker filling the room with sound that is almost as exciting as authentic
4-CH.
It may also be used to spatially enhance a monophonic source.
In this position the 4 | mode indicator lights will be illuminated, denoting
stereo to 4-CH operation.

VOLUME CONTROL
THE VOLUME control adjusts the signal level of any program material
connected to your receiver. It is a four section control which simultaneously
adjusts all channels, and its close tracking specifications insure that the relative
volume level of each channel will be identical.
SOUND FIELD BALANCE
Your 75+ incorporates a unique four channel continuously variable
balance control.
The nature of stereo or 4-CH reproduction is such that it requires identical
channels to attain the highest degree of faithfulness and spatial distribution.
Any variation in the efficiency of any channel as compared to the others will
disturb this relationship. Since there may be slight differences between program
material, room acoustics, efc., your receiver includes a control to balance all
channels, Sufficient range is covered by this control to permit rebalancing of
the overall system even in cases where major unbalance exists. This control
may be set anywhere within its range to attain system balance. It does not
necessarily have to be set in the exact center position.
When the BALANCE control is properly set, the apparent sound source
will lie in a broad area between all speakers.
