1 – This instruction manual

When using this product, basic safety precautions should always be followed to reduce the risk of fire and electric shock, including the following:

• Read and understand all instructions.

• Follow all warnings and instructions marked on this product.

• Do not use liquid or aerosol cleaners. Use a damp cloth for cleaning.

• To prevent fire or shock hazard, do not expose this product to rain or moisture. Do not use near a bath tub, wash bowl, sink, or laundry tub; do not use in a wet basement or in a swimming pool.

• To avoid electrical shock, do not open the case of this product.

• The unit should be situated away from heat sources such as radiators, stoves, etc.

The Sima speaker selectors have the following features:

• Ability to add up to 4 speaker pairs to your amplifier.

• Left and right “commons” are isolated to work with all types of amplifiers.

• Protection for amplifier.

• Small size to fit with any system.

• No power required for operation.

• Easy installation.

• Can handle up to 100 watts amplifier power.

1. Speakers on/off – Press button in to turn on all speaker pairs. Press again (button out) to turn off.

2. Amplifier selector – Press button in to select amp A. Press again (button out) to select amp B.

3. Volume control – An 11-step volume control for each speaker pair.

• 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 SIMA SSW-L4 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.

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 SIMA SSW-L4 EX terminals marked AMPLIFIER. Pay attention and connect the “+” output from the right front output on the amplifier to the right “+” input on the SIMA SSW-L4 EX and connect the “-” output from your amplifier to the “-” input on the SIMA SSW-L4 EX. Likewise, connect the left channel wires to the left input of the SIMA SSW-L4 EX.

• Next, connect the wires from each of the speakers to the corresponding connection on the SIMA SSW-L4 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.

It is recommended that you select only one speaker pair in the same room you are in for initial turn on. Select this speaker pair and turn on your receiver/amplifier. Make sure sound is coming from both speakers. Before you turn on additional speakers, read the information below.

Turning the level control fully counter-clockwise to the OFF position will turn that speaker pair off. Turning the level control clockwise will increase the volume in approximately 3 db steps.

Note: Refer to your amplifier or receiver’s user manual or on the rear panel of the amplifier to determine the minimal speaker impedance that your amplifier can handle.

• Make sure correct speaker is selected.

• Make sure correct amplifier is selected.

• Make sure no wires are touching each other or the case of the amplifier or SIMA SSW-L4 EX selector.

• Make sure the connectors are plugged in correctly.

• Reduce volume level of amplifiers.

• Turn unused speakers off.
