Data Sheet AB-3.2 Automatic A/B Selector The Russound AB-3.2 Automatic A/B Selector pro- vides automatic switching between two amplified audio sources. It offers the convenience of sharing one set of speakers in a given location between two different sources such as a local stereo and a multi- room audio system. For example, the AB-3.2 can be used to interrupt a distributed audio signal to play a local source through the room speakers, or it can be used to interrupt a local source (e.g., television in a lobby) with paging so announcements can be heard over the speakers. The AB-3.2 normally passes the amplified signal con- nected to its A input. When it senses a signal at its B input, the selector switches to that signal. When that signal ceases, it switches back to the original signal. The AB-3.2 includes a sensitivity trigger adjustment to adjust the volume level where switching occurs. It also includes a delay adjustment to prevent unintend- ed switching during quiet passages in a signal such as a movie soundtrack. The improved design of the AB-3.2 places all connec- tions on one surface for easier access and increased flexibility. The space-saving design will fit into many popular structured wiring panels. Detachable color- coded snap connectors allow connections to be prewired before installation for quick, easy and reli- able installations. The AB-3.2 is powered by a 12VDC detachable power supply (included). Country-specific 12VDC detachable power supplies can be substituted for use outside the U.S. Like all Russound products, this selector is ideal for use in either home or office in a wide variety of appli- cations. Key Features: • Automatically switches to alternate amplifier input when signal is present • Sensitivity and delay adjustments to fine tune each installation • Removable color-coded snap connectors make connections easier and more reliable • LEDs provide visual indication of power on and switching engaged to reduce installation time and eliminate guesswork • Designed for quality audio performance and long- term reliability Improved design saves space and installation time, adding convenience and flexibility
