If you have gone to the expense of having distributed audio in your home the volume controls may be letting you down. Most volume controls are very poorly designed and are seldom capable of handling the power from a larger distributed audio amplifier without causing insertion loss and added distortion. If you have (or want to have) a really rocking sound in your remote rooms check out these bad boys from SpeakerCraft.
Able to handle the output of amplifiers with up to 120 watts per channel without distortion and with a quality look and feel, it’s an easy upgrade to your system.
The picture shows the capacitor network on the back of the control with one already inserted in the wall.
