6.  Using the appropriate volume control on the front of
the SVL-6, adjust the volume of the speakers to the desired
listening level.

7. You can turn off the speakers by turning the appropri-
ate volume control on the SVL-6 fully counter-clockwise
or by pressing the ON/OFF button.

Playing Two or More Speaker Pairs
Simultaneously

1. 

Make sure the amplifier or receiver power is OFF and

set the volume to minimum.

2. On the right side of the SVL-6's front panel is a button
labeled PROTECTION. This button activates the SVL-6's
impedance correction circuitry. The circuitry assures that
your receiver or amplifier will see a safe operating load
when playing multiple speaker pairs simultaneously. Since
most receivers and amplifiers are not rated for use below a
4 ohm load, you will need to activate the PROTECTION
button whenever the overall system impedance might fall
below 4 ohms. Use the following chart as a guide for set-
ting the PROTECTION button.

"TECH TIP"

You will need to 

activate the SVL-6's

PROTECTION button

whenever the 

overall system

impedance might 

fall below 

4 ohms.

WHEN PLAYING THE FOLLOWING :

1 or 2 pair of 8-ohm speakers

3 or more pairs of 8-ohm speakers

1 pair of 4-ohm speakers

2 or more pairs of 4-ohm speakers

Any combination of 4 and 8 ohm speakers
