rigma Posted February 20, 2006 Author Share Posted February 20, 2006 Chris, As far as I can tell the only difference is the 75A is black, maybe to match the other A series where the 75 is trimmed in silver. The 75 does have the 1/4" inputs and the XLR balanced inputs. The amp sounds great as is with nothing needed. The only service this amp has seen since I had it was to drive the tweeter of my Khorns. Rigma, PM me if you like Quote Link to comment Share on other sites More sharing options...

Rigma, PM me if you like I don't foresee any big problems with it not being an A series. I just don't want to have to do any service and I thought it was a newer amp. Can I run unbalanced into the XLR inputs? I am using unbalanced XLR on all of my pro gear and would like to stick with the same stuff.

rigma Posted February 20, 2006 Author Share Posted February 20, 2006 Chris, You can wire the XLR as unbalanced, see http://www.crownaudio.com/pdf/amps/125243.pdf for details. If you decide you don't want this amp please refuse shipment and I will refund your money. Quote Link to comment Share on other sites More sharing options...

BS Button Posted February 24, 2006 Share Posted February 24, 2006 Rigma just bought back his 150. Quote Link to comment Share on other sites More sharing options...
rigma Posted February 24, 2006 Author Share Posted February 24, 2006 Yea, I want to try the Bi-Amp thing one more time, this time using the Marchand XM-46 passive crossover that was mentioned here a few days ago. If I don't like it the 150 will be for sale again. Stay tuned. rigma Quote Link to comment Share on other sites More sharing options...
Myhamish Posted February 25, 2006 Share Posted February 25, 2006 Just to mention, Rigma, that I've been bi-amping with a couple of Crowns for years. A DC 300A strapped for mono does the bottom with a D150A doing the mids and tops with a Crown VFX2 doing the crossover points. The top speakers are the Heresys and the bottom is the sub cabinet with 2 KEF B300 12" woofers. I have the xovers set for about 100 hz. I've got one other DC300A strapped for mono doing the other KEF sub with the HT setup with the Yammie RXV1300 and the RF3s. Years ago, I actually was tri-amping with three Crowns using the VFX2 for an adjustable mid to hi point and a dbx subharmonic synthesizer set at 120 doing the bass. Then, (before Klipsch) I was using KEF components (my subs are DIY leftovers from that phase and I still love them - actually, in the fall, I just scored a couple of KEF Cadenzas in a Value Village find - really an outstanding speaker but thirsty for clean power). There's a lot of advantages to having your own adjustable xover points and adjustable volume for different drivers. (Lots of disadvantages too). Biggest advantage is the power where you need it. Biggest disadvantage is hum and shorts from too many cables, dirty pot contacts and risk of meltdown by doing something dumb. Hamish Quote Link to comment Share on other sites More sharing options...
