So I'm considering picking up a QSC PLX 1602 or 3402 to use with my Acme Low B2 (running in stereo or bridged mono, depending on which model I go with). Andy over at Acme seems to think that in terms of consistent DC current, there's no substitue for either enormously heavy capacitors or an enormously heavy transformer. Anyone have any opinions on the PLX's performance in this area? Power drops, "brownouts", etc.? Bob, what's the theory behind the PLX's output system, and how does it address this issue?
