Aaron's ZA-100 stereo amplifier is specifically designed for multi-room use delivers, 50 watts per channel of power. If you do not need stereo sound, because there is only a single speaker in a particular room, you can link the left and right channels to increase power output to 130 watts.

You can toggle the amplifier between normal and signal-sensing modes. When signal-sensing, the amplifier switches itself on and off automatically by monitoring whether there is an audio signal at its inputs. There are two line-level inputs. Line 1 input has priority over Line 2, so a local user can instantly override a remote signal by plugging in an iPod or MP3 player.

There is also a line output on the unit, allowing it to be "Daisy-chained" with additional amplifiers for increasingly complicated and large installations.
