3. 

Set the SVL-4AB volume controls which correspond to the

speaker pairs you wish to play to maximum (fully clockwise). 

4. 

Locate the appropriate ON/OFF buttons on the SVL-4AB.

Set them to the ON position.

5. 

Adjacent to the ON/OFF buttons are the amplifier A/B but-

tons. Choose an amplifier for each active speaker pair by
pressing the A/B button in for “B” and out for “A”.

6. 

Turn on the amplifiers or receivers and select a source,

such as the tuner or CD player.

7. 

Slowly turn up each of the amplifiers or receivers volume

and set it to a comfortable (not maximum) listening level. Be
careful not to overdrive or "clip" your amplifier. If the sound
becomes muddy or distorted, you have reached the limit of
your amplifier's volume capability and should quickly reduce
the volume to avoid damaging your speakers.

8. 

Using the appropriate volume controls on the front of the

SVL-4AB, adjust the volume of the speakers to the desired lis-
tening level. The volume control of your receiver or amplifier
acts as the master volume for all of your speaker pairs.

When playing the following speakers:

1 or 2 pair of 8-ohm speakers

3 or 4 pairs of 8-ohm speakers

1 pair of 4-ohm speakers

2, 3, or 4 pairs of 4-ohm speakers

Any combination of 4 and 8 ohm speakers

The Protection button should be:

OFF

ON

OFF

ON
ON

Set the PROTECTION button to the correct position using the chart shown above.

"TECH TIP"

The volume control

of  your amplifier or
receiver acts as the

master volume for all

of your speaker

pairs. Set this control

to a comfortable (not

maximum)) listening

level. Be careful not

to overdrive or “clip”

your amplifier. If you

hear distortion from

your speakers

reduce the volume of

your amplifier to

avoid damaging your

speakers.
