Compact Class-D Stereo Amplifier

It delivers 2 x 15 W output power and features a built-in web-based control interface, four stereo line inputs, and one microphone input with phantom power

The multiple stereo line inputs allow simultaneous connections from different sources, while a microphone remains connected

Input switching, volume adjustment, and other controls can be managed from any computer with a web browser—no additional software required. The RS232 connection also enables control of the AMP523 via any device that supports serial communication

Additionally, the system can be controlled via smartphone or tablet using the specially developed AUDAC Touch™ app

A variety of optional mounting brackets allow for installation on a desk, in a cabinet, or in a 19″ equipment rack
