Ok so a week and a half and $150 later my mixer is fixed Invoice says "Dismantle Mixer, Locate Faulty Buffer Amp on Output + Replace, Assemble Unit" Does anyone know, would this affect the sound becuase i swear some songs sound different threw my speakers now & i now have to turn the Master Volume way up to get close to peak.... and would it affect the sound that comes out threw my headphones because when im listening to the master output threw 1 ear and ch1 threw the other it sounds like the master is distorting or something...i dunno maybe im just being paranoid...
