PhonoMatrix is a software suite aimed at controlling DaytonAudio DAX66 and Monoprice 10761 multizone amplifiers. It is composed of an agent which controls the amp via serial/RS232 and exposes a web interface. It has an optional iOS app too.

Is it free?

Agent and web interface are free to install and use. The iOS app is also free but a premium version may come along.

How does it work?

The service runs on Debian (and Raspbian) at the moment. Please contact us if you would like to test in on Windows or macOS. It exposes a JSON and WebSockets API for the iOS app to consume. We also support MQTT topics to interface the amps with other automation systems.

You need to connect the host to the main amp via an USB-RS232 cable.
