The Russound AB-2.2 is a compact tabletop A/B selector for shelves and equipment cabinets. It lets one pair of speakers be driven by either of two amplifiers, or lets a single amplifier be routed to one of two speaker pairs, all with one push of a button.
A common use is a family room where a stereo receiver plays the TV or turntable through the same in-ceiling speakers that are also connected to the whole-house audio system. The AB-2.2 keeps those two amplifiers from ever being connected together while making switching between them effortless. Connections use detachable, colour-coded snap connectors that take up to 14 AWG speaker wire, and the switch is rated for 150 watts RMS per channel, enough for typical residential amplifiers and receivers. Its small footprint sits neatly beside a receiver or on a cabinet shelf. Russound backs it with a 10-year warranty.
Key Features
- One-button A/B switching
- Source-select or speaker-select wiring
- 150 W RMS per channel
- Detachable colour-coded connectors
- Tabletop / shelf placement
Ideal Applications
Media rooms, offices, dens and equipment closets where a local amplifier and a multi-room system need to share speakers without rewiring.
Compatibility
For conventional low-impedance speaker circuits with stereo amplifiers and receivers; not for 70V lines. When one input is fed from a multi-zone distribution amplifier, Russound recommends running that zone through an impedance-matching volume control such as the ALT-126R before the AB-2.2.
