Hi! Sorry If my question is out of place but I've had the Vox mv50 AC for almost a year now - with the matching BC108 cab and I love its sound but I still have some usage question I can't find any answers online or in its manual: 1. I keep my impendance switch on 8 ohms - as recommended for the cab I have. If I were to switch it to 16 ohms, would that mean It would get quiter or is there a chance I might burn something in the speaker/cable? this didn't help me whatsoever. 2. I once, by mistake, connected the phone/line out output to the cabinet. It was quieter but I was happy to see the VU meter jump up and down (at the volumes I usually play, it doesnt even flinch). So my question is, can I damage something by playing it that way?. judging also by the fact that the cabinet doesnt have its own power supply, it gets its "power" through the cable 3. If I only have 3.5mm headphones (the jack), can i use an adaptor and use the MV50 with a regular pair of headphones without damaging the amp? I know that for some these questions are silly but I'd rather be safe than sorry. As you can tell this is my first amp that isn't a solidstate combo.
