The SVL-4AB includes impedance correction circuitry which
protects each of your receivers or amplifiers from low imped-
ance loads. The circuitry assures that both of your receivers or
amplifiers will recognize a safe operating load, even when one
amplifier is playing all four speaker pairs at the same time.
The actual impedance load the SVL-4AB presents to each of
your receivers or amplifiers will vary, depending on how
many speaker pairs are playing, and the impedance rating of
each speaker. If you have four pairs of 8-ohm speakers play-
ing from one of your receivers/amplifiers, the SVL-4AB will
present a 4.5 ohm impedance load to it. With four pairs of 4-
ohm speakers playing, the load drops to slightly under 4
ohms.
It is recommended that you use the SVL-4AB with receivers
or amplifiers that are capable of driving a 4-ohm load.
Consult your Niles dealer, or the receiver/amplifier manufac-
turer, if you are uncertain about the capabilities of the
receiver/amplifier.
Type of Speaker Wire
For most applications, we recommend you use 16 or 18
gauge stranded copper speaker wire for the SVL-4AB connec-
tions. For wiring runs longer than 80 feet, 14 gauge wire is
recommended. Using speaker wire larger than 14 gauge for
the SVL-4AB connections is not recommended — the wire
