Typical Hook up
Installation Tips
• It is recommended to use 18 or 16 AWG gauge stranded wire. For runs longer than 50’, 14 gauge is recommended.
• You can mix 4, 6, 8 and 16 ohm speakers.
• Since speakers have different efficiencies, more efficient speakers will sound louder than less efficient speakers. Either select your
speakers to have the same efficiencies (a typical measurement is 90 db/watt) or add a speaker volume control between the SSW-L4/L6 EX
and the speaker in the room where the speaker is located.
• Wire according to state and local laws. Most places require that you use special in-wall speaker wire with a specific “CL” fire rating.
Consult your dealer about obtaining such wire.
• Keep the speaker wiring from running close to AC power wiring for safety and to avoid any noise pick up.
Installation
Make sure your receiver or power amplifier is turned off before doing any wiring
• To make a connection, using a wire stripper, strip 3/8” of insulation from the end of the wire. To avoid short circuits and possible
amplifier damage, do not strip too much insulation from the wire.
• Tightly twist the end of the wire so that there are no frayed wires.
• For wiring convenience, connectors unplug from the connector block. Verify that there are no wire frays.
• Insert wire and tighten the terminal screw using a small screwdriver. Connect the wires from the speaker output from your receiver or
amplifier to the SSW-L4 or L6 EX terminals marked AMPLIFIER. Pay attention and connect the “+” output from the right front output
on the amplifier to the right “+” input on the SSW-L4 or L6 EX and connect the “-” output from your amplifier to the “-” input on the
SSW-L4 or L6 EX. Likewise, connect the left channel wires to the left input of the SSW-L4 or L6 EX
• Next, connect the wires from each of the speakers to the corresponding connection on the SSW-L4 /L6 EX.
• If you are using a second amplifier, connect it to the AMP B terminal.
• Plug connectors back into the unit. Warning: Be sure connectors are plugged in correctly – do not shift over one pin.
