Help With Crown Limiter Settings On JBL SRX Rig...

[Lance Richens]

Hello.
I'd like to get some ideas where to set the limiters inside the dsp of the amps powering my srx rig. I am using dr+'s as processing, but I'd like to do the limting in the amps themselves.

I am running 4 SRX 728's off of two I-Tech 8000's

I am running 4 SRX 725's off of two I-Tech 6000's (the woofers)

Running the said SRX 725 Horn Sections Off of 2 XTI 2000's

I'd rather be on the cautious side than max output side.

Application is all over the board from bands to EDM.....

Why not just do all of your processing with System Architect or Band Manager in the amps and sell the DriveRack? If you were fiddling with the DriveRack at the board end of the snake then you might want to keep it but you don't need it with those amps. Just make a bunch of presets with names for all of your different speaker applications. You do have a laptop with System Architect or Band Manager right?

Heh... well, the XTi limiters are basically "Off", "Some", or "More". Not very useful IMHO, but then again limiters on horns rarely are anyway. I believe they're peak limiters, which aren't likely to solve any of your problems.

I always suggest setting a power limiter at 1/2 the AES rated power of your woofer, relatively slow attack and release (seconds). The iTechs do this very well. This will keep your rig very consistent, as the voice coils won't really be able to heat up and change character. If they can't heat up they're pretty hard to destroy, too! That would end up being about 400 watts per woofer in your 728s. If you think I'm crazy, I suggest a) you try it and b) stop thinking in watts except in terms of real heat load, and then think of your woofer giving off as much heat as four 100 watt light bulbs and see if you don't still think that's a lot of power.
