I just published a first version of my new ‘Rotel Volume/Source Control Extension’ on GitHub:
It uses the network interface (not RS232) of a Rotel amplifier to control volume, source and standby. I’m using it with my Rotel RC 1590 preamp but it should work with other Rotel devices, too, as long as the protocol is equal. This depends on the exact model and/or firmware of the Rotel amp.
Are there any Rotel users around here? Which Rotel amp do you use?
Any feedback is welcome, have fun!
