The Russound AB-1.2 in-wall "A/B" selector comes in handy for two different types of custom audio installations. Use it to safely switch between two different powered audio systems you connect to one pair of in-wall speakers. Or, send music from a single audio system to one of two pairs of connected speakers. Hum along to your favorite music in the kitchen while you cook, then switch to your patio speakers while you enjoy an outdoor meal.

Product Research


Overview: The Russound AB-1.2 is an in-wall, speaker level selector switch with two wiring options; a single pair of speakers can be driven by either of two amplifiers (source switch), or a single amplifier can drive either of two pairs of speakers (speaker selector switch, only one pair at a time). It has a mechanical button to switch between the dual amplifier or speaker pairs.

Installation: The AB-1.2 is an in-wall switch that fits into a standard single-gang junction box.

Note: A Decora wall plate is required, and not included.

Connections: There are three removable, color-coded, screwless snap connectors that accept up to 14-gauge wire. These connectors have wire locking levers which snap the speaker wire into place.

Specifications: The AB-1.2 is designed for use with amplifiers with a power output of up to 150 watts RMS per channel.
