Audac AMP523 Web Based Mini Stereo Amplifier – Doneo Malta

The AMP523 is a Mini Stereo Amplifier with an Inte – grated web based control unit, featuring four stereo line inputs and one balanced microphone input with phantom power. It has an output power rating of 2 x 15 Watt.

The simple and compact but versatile functionalities makes it perfectly suited for small speaker systems requiring compact and economical audio solutions which are comprehensive and easily controllable.

Some typical applications are classrooms where the audio system will be used in combination with a smartboard, offices and meeting rooms where the music should switch automatically from background music to speech or playback when the presentation starts, …. And many other similar applications.

The compact size and very high efficiency even makes it possible to hide it in a closet, on a false ceiling or mount it under a desk or table. The vari – ous stereo line inputs allow simultaneous connec – tions for different sources such as Laptop’s, CD or MP3 Players, Tablets, while having a microphone connected.

The switching between the inputs, volume regula – tion and other function controls can be done in mul – tiple ways: an integrated website makes it possible to control all the functions from any computer with a web browser without requiring additional software, while the RS232 connection makes it possible to control the AMP523 with any device supporting se – rial communication, such as a computer or even a home or industrial automation system.

Another op – tion is to control the system through smartphones and tablets using the special developed Apps. Optional MWX43 or MWX45 wall panels can be in – stalled to control the signal routing and volume level from one or multiple fixed locations.
