Features

A/B Selector: The Russound AB-3.2 A/B Selector allows for automatic switching of two amplifier's outputs to a single pair of speakers. This lets you use one pair of speakers to play two different amplified sources without having to manually switch between them.

Connections: The AB-3.2 has three removable, connector blocks, accepting up to 14-gauge wire. These connectors use screw-down termminals to secure the speaker wire into place.

Automatic Selection: The A/B Selector's three connector blocks consist of two inputs, Amp A and Amp B (interrupting), along with a Speaker Output block. The Amp A input is "normalized" to the Output block, but when a signal is sensed on the Amp B input, the selector will switch to that input source. When the Amp B interrupting input is no longer active, the unit automatically switches back to the Amp A input. This can also be used in conjunction with a microphone to interrupt the sound source when a paging announcement is made. A green LED indicator lights when Amp B is active.

Trigger & Delay: The Amp B interrupting input includes sensitivity adjustment dials for both Trigger and Delay settings:

• Trigger: This adjusts the volume level of the interrupting signal where switching occurs. Lower levels will decrease the Selector's sensitivity to incoming signals, while higher levels will let the Selector switch with very little signal present.
• Delay: The Delay allows you to adjust how much "silence" can occur before the interrupting input switches off. This is handy for allowing dead space between CD tracks to pass without the Selector switching back to the Amp A input.
