OK, here's the deal. I have $3400.00. I plan to upgrade my power amps.
Here's what I have.
3 RMX 2450's
1 RMX 4050HD
1 PLX 3602
and the 'ol Driverack PA.
I have a pair of SRX 722's and three SRX 728's. I haven't bought a forth sub YET because I wouldn't be able to fit it my van anyway. I've been using an RMX 4050HD on the subs and a PLX3602 on the tops. I use two of the 2450's for four monitor mixes.
I've ran several other 728 / 725 combos with bigger power and more headroom. I don't have much headroom. I just can't stand to see the red lights on the 4050HD flashing with every kick drum hit anymore. With only $3400.00, I didn't think I'd be able to get enough of the correct amps to be able to bi amp my tops. So I just figured I would just get a used Itech 6000 and an Itech 4000 and at least be better off than I am now.
The good - I love the weight of the Itechs. I like the 4 ohm stereo rating. I like the power draw - which is VERY important to me.
The not so good - I am intimidated by the DSP. I don't like the 2 ohm stereo rating. I'd need to be able to run two 728's per side of the IT6000, but the stereo 2 ohm rating is only 2500 watts.
So then I started thinking about the QSC PL380. I don't know a whole lot about them really. I love the ease (no DSP to mess up) of operation. I love the stereo 4 and 2 ohm rating. The weight is good but I'm pretty sure I've read in some older posts that they draw a lot more AC than the Itechs. I often only get 2 circuits for PA...
Then I thought about bridging, which I'm a bit afraid of doing anyway. I think I'd really draw a lot of AC and add a lot of weight to the amp rack though. I'd love to be able to bi amp the 722's. I don't know what to do exactly. I've got $3400.00 and the amps I listed above.
A buddy of mine uses an XTI 6000 on his 728's and an XTI 6000 on his 725's. The rig sounds good but the sub amp seems to strain (?) a bit, like the recovery isn't quite there? Plus, it seems used IT4000's and IT6000's are cheaper than XTI 6000's anyway.
I really don't know what to do. IF you were in my situation, what would you do?
Thanks everybody.
