Niles Audio HDL-6 User Manual

Page 6

The actual impedance load the HDL-6 presents to your receiver
or amplifier will vary, depending on how many speaker pairs
are playing, and the impedance rating of each speaker. If you
have six pairs of 8-ohm speakers playing, the HDL-6 will present
a 4.3 ohm impedance load to your receiver/amplifier. With six
pairs of 4-ohm speakers playing, the load drops to slightly
under 4 ohms.

If you intend to use the HDL-6 with more than two pairs of
4-ohm speakers, it is recommended that you verify that the
receiver or amplifier is capable of driving a 4-ohm load. Consult
your Niles dealer, or receiver/amplifier manufacturer, 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 HDL-6 connections. For
wiring runs longer than 80 feet, 14 gauge wire is recommend-
ed. Using speaker wire larger than 14 gauge for the HDL-6 con-
nections is not recommended—the wire may not fit into the
connectors. Never use solid-core, aluminum, or "Romex" type
wire with the HDL-6. When running speaker wires inside walls,
most states and municipalities in the U.S. specify that you must
use a special type of speaker wire. Usually, the requirement is
that the wire has a specific "CL" fire rating, such as "CL-2" or
"CL-3". Consult your Niles dealer, building contractor, or local
building and inspection department if unsure about which type
of wire is best for your application.
