Where space is at a premium, or you just want to fit a player directly to the wall, this is the ideal solution. Play MP3 files, radio or plug in an external device and use the internal amplifiers to power speakers directly. The amplifier can be used in stereo, or stereo signals can be mixed to mono for dual zone use. A music on hold feature will allow seamless integration into a fire evacuation system and hidden panel controls can help avoid excessive sound levels. The amplifier slides easily onto wall fixings and it can be fitted anywhere where there is reasonable air circulation.
