Before using this control, set up each left-front, right-front, left-
back and right-back channel level as directed under “Four-channel

ponse, counterclockwise to decrease response, Adjust to your
preference.

SQiet eden for SQ listening when playing SQ programs or con-
ventional stereo programs*.

other-type matrix programs.
2->4...... for obtaining ambience effects with conventional

late at night or reproducing background music while reading.
The sound will be heard with an apparently flat output from the
bass to the high range. This switch affects both the front and
back channels, therefore turn off any front amplifier loudness
control.
