Author Topic: Help with Crossovers? Tissa DeSilva Film Handler Posts: 36 From: Toronto, Ontario, Canada Registered: Jul 2007 posted 05-17-2012 07:58 PM                     I am using QSC RMX amps with JBL 4675 speakers, KIndly tell me what kind of crossovers I should use? I can not change the amps because I have them already.  |  IP: Logged Randy Stankey Film God Posts: 6539 From: Erie, Pennsylvania Registered: Jun 99 posted 05-17-2012 10:04 PM                     Depending on the version of that speaker you might not need crossovers. I have the "regular" version of that speaker. (4675C) There is a passive crossover built in to the cabinet. The high frequency horn connects to a pair of terminals on the side of the cabinet then the wires from the amplifier connect to the inputs. The device inside the cabinet does all the work for you. A lot of the time, this passive crossover is all you need. Yes, you'll get better performance if you use a separate crossover and biamp the system but it is not entirely necessary. The decision is up to your audio engineer. Personally, I would do it if I could but my speakers are hooked up as passive crossover and they sound just fine.  |  IP: Logged Jeremy Weigel Phenomenal Film Handler Posts: 1062 From: Edmond, OK, USA Registered: Mar 2007 posted 05-17-2012 11:57 PM                     We use the JBL 3160 external mounted cross-over. They're discontinued, but you can probably find them on eBay.  |  IP: Logged Tissa DeSilva Film Handler Posts: 36 From: Toronto, Ontario, Canada Registered: Jul 2007 posted 05-18-2012 07:04 AM                     Hi Randy Iam using JBL4675 stage speakers and no crossovers build in.  |  IP: Logged Dave Macaulay Film God Posts: 2321 From: Toronto, Canada Registered: Apr 2001 posted 05-18-2012 07:37 AM                     This is not enough information. Do you want a bi-amp system or a passive crossover system? For bi-amp there are a lot of crossovers available. I would use Odyssey personally, pretty inexpensive and reliable (so far). Passive, I don't know. The matching JBL crossover would be best I think.  |  IP: Logged V.V.Tushit Vijay Film Handler Posts: 54 From: Tenali, Andhra Pradesh, India Registered: Oct 2009 posted 05-20-2012 07:02 AM                     Hi Tissa , Nice to see you here back to film-tech. And i suggest you to go for XTA DSP OR Ashly DSP. Which makes the better vocal and digital delay correction for the Auditorium . Regards, Tushit  |  IP: Logged
