“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.
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.
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
18gauge, 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
14gauge 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.
