[QUOTE="John Roberts, post: 93010, member: 126"] Re: New QSC amp ???? Tripath came in to Meridian and gave us a presentation. IIRC they were interested in selling modules to manufacturers to use in audio power amps. I was not very impressed by their response to what I thought were pretty basic power amp design questions. I think there was a college professor behind the basic Tripath invention, and some business types invested in his idea to be the next "game changer", but stuff happens. I don't think the professor was there for that particular MS dog and pony show. I'm just guessing, electric cars, windmill convertors, something other than pro audio is driving device technology. Universal switching power supplies can handle 240V x 2.8 x +20% volts so that enough volts to make some serious audio power, but the uni-switchers are not high current for typical consumer goods so we need the volts and amps to make serious output power with single devices. Perhaps UPS for large computer installations but i don't know what battery voltage they size those for. They do some crazy high power stuff where the major power grids meet. I think they convert both sides to DC to avoid the pesky phase matching issues, for power transfers between major grids, but that's silly low volume stuff so just of academic interest. The military may buy a few for rail guns or pulse weapons. JR [/QUOTE]
