gbrlex Posted May 18, 2007 Share Posted May 18, 2007 I've read so many positive comments on the QSC amps that I'm wondering if anyone has had a chance to try them with the Legend Series KLF 30's. I'm currently using a Rotel 1095. Would I notice a substantial difference in performance in the 2 channel mode? Quote Link to comment Share on other sites More sharing options...
Duke Spinner Posted May 18, 2007 Share Posted May 18, 2007 not a lot Quote Link to comment Share on other sites More sharing options...
formica Posted May 18, 2007 Share Posted May 18, 2007 And one should not forget that pro-amps are fan cooled... so even though the PLX have multispeed units, they are audible in a quiet living room. Quote Link to comment Share on other sites More sharing options...
toadtobin Posted May 18, 2007 Share Posted May 18, 2007 do the fans even kick on if you're not driving the amp hard? Quote Link to comment Share on other sites More sharing options...
formica Posted May 18, 2007 Share Posted May 18, 2007 Yes, they are always on, but at a low speed. I find fans are most audible, dough, when music (or soundtracks) has a silent moment preceeded by a loud one... (amp heats up... and then suddeny there is nothing to mask the fan noise).

I have a QSC and the fan isnt audible even with your ear on the amp. And the QSC I have, I wouldnt trade it for 2 of those Rotels. But to be fair to Rotel the 1095 was designed for multichannel. And so not a fair comparison. Quote Link to comment Share on other sites More sharing options...
formica Posted May 18, 2007 Share Posted May 18, 2007 I realise that it'll greatly depend on placement, ambientnoise, and preferences. I was also using a QSC in room... so I swapped out theoriginal fan and installed one of the recommended models as per John Gordon (ofQSC) recommendations. They usually usethe high velocity variety because of the possible heavy pro use... but there isvery low risk in installing a low velocity one for home use. The variable speed continues to function,but the fan is simply turning slower at every preset level. In my current room, I opted to install my proamp in a separateroom ROb PS: At the lowest fan setting, my QSC CX was putting out about 65db at the fan mouth before the mod and 57db after. I believe you are using their studio series which should better that right from the factory... Quote Link to comment Share on other sites More sharing options...
gbrlex Posted May 21, 2007 Author Share Posted May 21, 2007 What model QSC are you using? Quote Link to comment Share on other sites More sharing options...
Mighty Favog Posted May 21, 2007 Share Posted May 21, 2007 Take it from someone who's had your setup on a smaller scale. I was using my KLF20's with a Rotel RB1080. I found that the Rotel didn't start to "come together" until after the first 3/4 of a watt. With speakers that are 100db senstive (102db in your case) that got to be a little too loud for what I wanted at the time. I sold the Rotel and bought a McIntosh MC252 and never looked back.
