the center front speaker, approximately five feet above the floor,
and pointed straight up.
Open the SA10 front panel.

the Cat. No. 811 card.
Set all gain controls on the four surround power
amplifiers to maximum. If a different setting is
required in order to optimize the noise performance of
the system, the controls should be locked in position or
marked clearly.

to Disable (switch in, LED off).
