Installation Considerations

SVL-4AB Power Handling

The SVL-4AB is designed for use with receivers or amplifiers
having a maximum power output of 100 watts per channel at
8 ohms. Damage caused by the use of higher-power receivers
or amplifiers will void the warranty. Consult your Niles dealer
or receiver/amplifier manufacturer if you are uncertain about
the power rating of your receivers or amplifiers.

IMPORTANT: DO NOT USE THE SVL-4AB 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 
connecting more than two pairs of speakers without using
some form of impedance correction.
