What was their RMS rating?
I'd be surprised if that was the design principle used for the class D stuff... but it's true that I don't really know the design history of that stuff.

Hey.. inducted into a 'Hall of Fame'!
150 W/ch X 2, rms at [forget.. "low"] THD, IM.
Seems that the DC-300 was inducted into the TECnology Hall of Fame [?] in '07, 40th anniversary of intro: http://www.crownaudi...m/press/pr157.htm 'Twas a heavy rack-mount-sized beast and, at $~680 in '67: cost Lots in the day. I was a Crown dealer; sold a few Crown prof. R-to-R tape recorders (one to the US Navy!) and a few DC-300s, but was then winding down this avocation. The build quality was excellent, near- Tektronix or hP grade.
PS: I have a pristine Crown IM Analyzer, Model IMA + perfect manual copy, available for a pittance (it also wasn't cheap in the day, though I snagged it off of eBay a few years back. Never used it.) |

Re: Hey.. inducted into a 'Hall of Fame'!
Well, I might actually be interested in some of that hardware... I'd really like to get an oscilloscope sometime so I could check out what's coming out of my guitar amps (I've got some nicely old ones, and they're all old tech). It's a great way to figure out just exactly where the signal starts to break up...
150W is pretty loud, but I bet it would have a hard time delivering the vocals in competition with a 50W tube guitar amp. Actually, I've got a far descendent of that; it's a Crown 802 XLS, develops 500W/side RMS at 8 ohms. If I bridge the amp, I can get it up to 1600W@8Ohms. Great amp, sounds great, but it weighs a ton (well, close to seventy pounds). I use it to drive the three JBL JRX112Ms that I have. I used to use two of them for FOH and one as a monitor for whoever was singing, but now that I've picked up those two powered enclosures I can go to running three monitors and two monitor mixes. All I need now is a sub running between 800-1000W, and the fundamentals of my PA are complete... mwahahahaaaaaa :) |
