Constant Protection Switch

The SVL-6 is equipped with a manual override for the protec-
tion circuit that enables you to defeat the front panel protec-
tion switch and maintain constant impedance protection. This
will safeguard your amplifier from being overdriven due to
accidental or improper use by anyone unfamiliar with the
equipment.

To engage this override, move the rear panel "CONSTANT
PROTECTION" switch to the "ON" position. Constant imped-
ance protection will be maintained until the switch is turned
to "OFF".

Balancing Speaker Volume

The volume control on your receiver or amplifier serves as the
"master" volume for all speaker pairs connected.

The volume level of the speakers may vary from room to
room.  This is caused by several factors. Two lesser factors are
the size of the speaker and its efficiency. The largest factor is
the physical size of the room.

The SVL-6's volume controls allow you to adjust the volume
of each speaker pair individually. You can leave the amplifier
or receiver volume set at one position and use the SVL-6 vol-
ume controls exclusively.
