    RDL ST-VCA3 reviews

    ST-VCA3 Voltage-Controlled Amplifier is rated 5.0 out of 5 by 2.
    Rated 5 out of 5 by from Solution Solver Using this to control wall speaker volume remotely to a stereo receiver in the next room. Works great working at line levels without having to have a huge high-powered speaker L-pad in the wall that eventually gets scratchy sounding and dead spots. Made by RDL which I've used in many custom installations in the past. Very reliable products, practically bulletproof! Had to get 2 for stereo.
