Time to upgrade my amps...


Joseph Dixon:

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.

interesting about amps that strain on the bottom end and concern about bridging and 2-4 ohm usage. i cant recomend anything new BUT i have never had any kind of strain problem or bridged problem or 4 ohm bridged operation with the old QSC Series 3 3800 amps. i have seven(7) QSC 3800 , i use 6 and for some unknown reason i bought a spare that i should at least find a use for and they kick ace on 18" woof woofs. i have heard that the Crest 8001 is a great kick bottom amp. maybe you could find a good used QSC 3800 or Crest 8001 for the subs. i have seen good used qsc 3800 amps for $400.00 and qsc still services them "IF" needed. as for power outlets we never played small clubs and were always ready to stick a generator out behind the club if we needed more power. i prefer a generator anyway. P.S. that QSC series 3 were probably the best amps ever made, they were way overbuilt like a CAT diesel is !!!
