That's it, a new version is available, v1.5 !!
The new V1.5 wallbox2mp3 released manages the sound a completely new way; The sound is now digitally managed until it arrives to its amp / jack output, so it's fully protected against Electromagnetic Interference, it's also protected by much more audio filters. The sound doesn't go any more throughout the remote pot ribbon but has been replaced by a simple current, so you can use a very long remote pot cable (up to 150 inches, more than 400 inches using an higher wire gauge) without any consequence on sound quality.
Moreover the sound amplifier is much more powerfull and can act as a class D (better efficiency) or a class AB (to sum up better sound quality) audio amplifier
While waiting for our v2 which should be released in the coming months… ..
