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.
4. Plug the terminal block connector into the SPEAKER OUTPUTS connector.
