A whole-house sound system distributes music and audio programming to speakers installed in multiple rooms of your home. Audio Distribution Amplifier modules by Impact Acoustics(?) are an easy, economical way to provide distributed sound. A line level input for a CD player, tuner or tape deck and 4 outputs supply speaker-level signals to volume controls mounted in selected rooms. Use this module in combination with IR distribution and you can select tracks on the disc or change radio stations from any connected room. These modules, designed for use with Impact Acoustics(?) Stereo Volume Controls, provide up to 20 watts per channel.
