4. Slowly turn up the amplifier or receiver 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 ampli-
fier's volume capability and should quickly reduce the volume
to avoid damaging your speakers.
5. To turn off the speaker pair, simply press the corresponding
on/off button on the SS-4/SS-6.

“TECH TIP”
If your amplifier
or receiver has “A”
and “B” speaker-
pair outputs, con-
nect the SS-4/SS-6
to the “A” outputs.
Do not connect any-
thing to “B”. This
will prevent the
amplifier or receiver
from driving an
unusually low
impedance load.
The actual impedance load the SS-4/SS-6 presents to your
receiver or amplifier will vary, depending on how many speak-
er pairs are playing and the impedance rating of each speaker.
If you have four pairs of 8-ohm speakers playing, the SS-4/SS-6
will present a 4.5 ohm impedance load to your
receiver/amplifier. With four pairs of 4-ohm speakers playing,
the load drops to slightly under 4 ohms.
If you intend to use the SS-4/SS-6 with more than 2 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 SS-4/SS-6
connections. For wiring runs longer than 80 feet, 14 gauge
wire is recommended. Using speaker wire larger than
14 gauge for the SS-4/SS-6 connections is not recommend-
ed—the wire may not fit into the connectors. Never use solid-
core, aluminum, or “Romex” type wire with the SS-4/SS-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 build-
ing and inspection department if unsure about which type of
wire is best for your application.
