Avin Avant3 DSP stops after a few minutes

[e39s62m]

Well, the I-Bus App do work fine?
Must be activated, also in menue DSP.
Please have a look in our wiki, point app setups: http://wiki.ibus-app.de
The AVIN itself can not handle the DSP, it's the app incl. the Resler Interface who do this.

Yes, the I-Bus app works (unlocked and DSP license activated). I can seemingly control DSP from the I-Bus app, changing level, room, echo, balance, etc., but no sound comes out.

From the WIKI it says to check that the amp is getting voltage and a remote, which I suspect may be the problem, but I'm not sure how to check that.
