PSI Audio vs Foundry Control

This is the official app to control PSI Audio AVAA units with the latest firmware. If you are looking for the legacy PSI Audio app (for older units), please search for “PSI Audio – Legacy” in the store. The AVAA is a unique active system to absorb low frequency room modes in a room. This application allows you to remotely control your AVAA(s) through your mobile phone. It also gives you access to all the information relative to your device such as serial number, firmware version, SSID, etc. You will also need this application to get access to the latest firmware and ensure you have all available features and optimised absorption. Furthermore, this application will give you general information on acoustics, room modes and how best to use your AVAA(s).
