Russound AB-3.2 Speaker Selector

The Russound AB-3.2 Automatic Speaker Selector is designed to provide automatic switching of two amplified audio sources to a single pair of speakers. The AB-3.2 will automatically switch from the main audio system (AMP A) to a local audio source (AMP B) when the local source is active. For example, connect the speaker output of your in-house audio system to the AMP A input, your TV room speakers to the speaker connectors, and the TV output to the AMP B input. If you are listening to the stereo (AMP A) and turn on the television (AMP B), the AMP B audio will override the AMP A audio and the TV sound will be heard over the local speakers.

The Russound AB-3.2 Automatic A/B Selector is an affordable solution for automatically switching a pair of speakers between two amplified sources. This allows you to use one pair of speakers in a room for two different sources such as a television and a multiroom audio system.

Through signal sensing, the AB-3.2 allows your local amplified source to override the default source for listening through the room speakers. When the local source is no longer active, the unit automatically switches back to the default source. Alternatively, you can use the AB-3.2 to interrupt a local source (e.g., television in a lobby) with paging so announcements can be heard through the speakers.

The AB-3.2 places all connections on one surface for flexibility and easy access. The space-saving design fits many popular structured wiring panels. Detachable color-coded snap connectors allow you to connect the wires before installation for quick, easy and reliable connections.
