Hello! Keep me crazy or something…. BUT I need a short-term stereo signal from the NCDC best to access the sound processor at best full frequency bandwidth (from low to high) there should be a 220V power amplifier and my thick PA-boxes on it (the whole is on a trailer and has n power generator) – the question is yes if the sound processor is also the amplifier … if yes, a pre-reinforced signal would have to arrive at the sound processor which I can pick up there e…. right? audio signal input has a galvanic separator so no should happen because of 220V in the trailer and 12V connected in the onboard network via preamplifier signal background I want to have short-term in the car full can BOSE sound and on the trailer the same music on the thick PA boxes run.
