SA-2

English

Stereo or mono output (SA-3 only)

The output of the SA-3 amplifier can be set to stereo (switch A up – factory setting) or mono (switch A down). The mono output mode feeds left and right channel audio to both the left and right outputs. This mode is useful in situations where a stereo output isn’t feasible such as when outdoor speakers are used in a large area.

Automatic detection of a local source (SA-3 only)

When a source is connected to the AUX INPUT connectors, you can set the amplifier to detect when that source is turned on, thereby automatically switching the amplifier from standby to on.

The amplifier is shipped with this feature turned off. For local source automatic detection, set switch B up.

Single and supplemental amplifiers

If you want to cover a large area, such as an outdoor patio, requiring more than one set of speakers, you can install additional amplifiers. See the setup for room C in “Setup guidelines for additional rooms” on page 22.

•Leave switch C down (factory setting – single amp mode) on one amplifier and set switch C up (supplemental amp mode) on all other amplifiers.

•Set the room code in all amplifiers to the same room code as in the remote control.

•Now, you can turn them all on and off, change their volumes, or mute them together using a single remote control.
