AMP523MK2 Web-based mini stereo amplifier 2 x 15W


Web-based mini stereo amplifier 2 x 15W

The AMP523 is a mini stereo amplifier with an integrated 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 make it perfectly suited for small speaker systems requiring compact and economical audio solutions that 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 make it possible to hide it in a closet, on a false ceiling, or mount it under a desk or table. The various stereo line inputs allow simultaneous connections for different sources such as laptops, CD or MP3 players, and tablets while having a microphone connected. The switching between the inputs, volume regulation, and other function controls can be done in multiple 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 serial communication such as a computer or even a home or industrial automation system. Another option is to control the system through smartphones and tablets using the specially developed AUDAC Touch™ app.

Using this freely available application for smart devices guarantees total system control and configuration from any device at any location and at any time. To make the installation even more complete, an optional MWX43 or MWX45 wall panel can be installed to control the signal routing and volume level from one or multiple fixed locations. The Class-D amplifier technology, standby mode and included switching power supply makes this device compliant to the highest energy efficiency and environmental requirements. A variety of optionally available mounting brackets for the AUDAC S-Box product range are allowing desk, closet, or 19” equipment rack installation.
