Installation Considerations

SVL-2 Power Handling

The SVL-2 is designed for use with a receiver or amplifier hav-
ing a maximum power output of 100 watts per channel at 8
ohms. Damage caused by the use of a higher-power receiver
or amplifier will void the warranty. Consult your Niles dealer,
or receiver/amplifier manufacturer, if you are uncertain about
the power rating of your receiver or amplifier.

IMPORTANT: DO NOT USE THE SVL-2 WITH AMPS OR
RECEIVERS RATED AT MORE THAN 100 WATTS PER
CHANNEL RMS AT 8 OHMS.

Amplifier Impedance Load

As more pairs of speakers are parallel connected to a receiver
or amplifier, the overall system impedance becomes lower.
For example, if two pairs of 8-ohm speakers are connected in
parallel, the impedance will be 4 ohms, two pairs of 4-ohm
speakers in parallel become 2 ohms, and so on.

Most receivers or amplifiers are not rated for use below a 4
ohm load. Most manufacturers do not recommend connect-
ing two pairs of 4-ohm speakers without using some form of
impedance correction.
