I'm new to pro audio and was hoping to get some help/advice here on a system I'm assembling.
I want to know if I'm going to risk damage to my speakers with my current setup. I just picked up a pair of JBL JRX 225 speakers. They're rated 500-1000 Watts continuous at 4 Ohms. I sort of put the cart before the horse and impulsively acted on a Woot deal for 2 Pyle Pro Pexa 3000 amps. They're rated as follows:
- 250W X 2 @ 4 Ohms
- 150W X 2 @ 8 Ohms
Bridge Mono Mode
- 500W @ 8 Ohms
I'm currently running 1/8" headphone jack split to 2xXLR with one channel into each amp's input channel A. I'm then running a speaker per amp from the bridge output. Basically, I believe I'm getting 500W @ 8 Ohms into each speaker. Does this sound correct, and is this OK or a recipe for disaster?
Why would you torture yourself with PYLE of all brands? They are absolute garbage!
If you're that strapped for cash, you could've gotten a QSC GX3 for $300 USD!
You're absolutely right. Unfortunately, I now realize this after the fact. I usually put a LOT of time and effort into my purchases, but the allure of the deal won out this time. I should have waited!
I'll have to dump them on Craigslist or Ebay and try to recoup funds for something better like the QSC. There are some Crown amps out there that are cheaper per watt. Any experiences with them, good or bad?
Thanks for the suggestions guys. I opted to go for the GX7.

And yes..buy a decent amp such as the QSC GX3.
Also, the headphone output is normally a driven output and not line level. That means you can be over driving the input to your amp. You should use a line level output if at all possible.
Mark, that's a really interesting point about the headphone jack I hadn't considered. I had been told by multiple folks at Guitar Center "yeah, just plug it right on in, you'll be good to go. It's what most people do" and just took it in good faith.
Is there a device I can buy that can properly adapt a non-line level input to a line level output? I had decided I don't need a mixer for such a simple setup, but is this possibly one of their functions?
I feel so funky being a n00b I've been a computer programmer for 10+ years and I'm used to just writing a quick test when I want to verify something, but easier said than done in this case because buying equipment isn't cheap!
