In-wall A/B selector
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.
Works perfectly. Used to select either one of two amplifiers feeding one set of speakers. Easy to wire. Directions perfect.
