Connecting speakers to the SA-4 amplifier

CAUTIONS:

•Use only unpowered speakers. DO NOT connect any make or model of powered speakers. Doing so may cause damage to the equipment.

•The SoundTouch™ SA-4 amplifier requires a 6-ohm minimum load.

Speaker cables consist of two insulated wires. Often, one wire is marked (striped, colored, or ribbed), indicating it should be connected to the positive (+) terminal. The plain wire should be connected to the negative (–) terminal. For recommended wire sizes and lengths, see “Speaker cable recommendations” on page 27.

1.Disconnect the SA-4 amplifier from AC (mains) power.

2.Remove the terminal block connector from the SPEAKER OUTPUTS connector on the rear panel of the SA-4 amplifier.

3.Use a small, flat-head screwdriver to connect the left speaker cable to the L positive (+) and minus (–) terminals of the 4-pin terminal block connector, and the right speaker cable to the R positive (+) and minus (–) terminals.
