    ok well i am about to finish my new rig and all i need is to pick my power amp i have a limit of $600 so i have two choices, QSC RMX2450 Power Amp or carvin dcm2000? which would yuo choose to go with a eden navigator? i need at least 400 per side into 8 ohms so if yuo know of any other amps let me know.

    also is there a big difference between the qsc plx and rmx?

    thanks,

    The difference between the RMX and PLX is about 20 lbs and the design. Don't know the exact weight difference but the PLX's weigh 21 lbs and are great power amps.

    Personally, I'd look for a good used PLX2402 or PLX3002.

    The PLX is a 2 space amp, the Carvin might be a 3 space but I'm not sure where the breakpoint is in their line between 2U and 3U chassis.

    QSC power amps are UL Listed for safety. I don't believe that Carvin amps have any third party safety certifications (the CE Marking is a self-certification mark and means just about nothing).
     
  3. I have used Carvin amps in the past and they were ok, thats all.
    I have not used QSC, however I know folks who do use the PLX series and they sound really good.

    Choice - QSC
     
  4. I've got a dcm1000 and a plx 1202 and I've used the RMX stuff in some bands I was in. They all do the same thing and that is amplify the signal really well. The real differences I see are: Carvin 3U, RMX and PLX 2U. The PLX is quite a bit lighter than both the Carvin and the RMX. Both the PLX and the CARVIN are made in the US where the RMX is made in China. (some may consider that a difference) As for how any of them will sound in your bass rig. I don't think anybody would be able to hear any difference........................jmo................and........

    Between my own rig and my band's PA, we have used RMX2450, PLX3002, PLX2402, Series One 1700 (old QSC model), Crown CE2000 and a Carvin DC2000.

    The RMX 2450 is for sale because the weight difference between it and its PLX brethren is so great, ESPECIALLY when you are coping with several amps in one rack. I would add to the previous suggestion: Buy a PLX2402 or 3002 on eBay. Your back will thank you.

    The CE mark means that the appliance meets the safety codes required by the European Community. It is not self-awarded, but is subject to testing by a lab that is itself certified to conduct such evaluations. Often the same labs that test for UL also test for CE.

    AFAIK, CE certification is legally required for anything to be sold in the EC. UL listing, however, is not legally required in the US, but many local electrical codes may require it.
     
  7. I'm pretty sure that any Carvin poweramp under 2500w is 2U. I'll have to double check that one.

    No, Bill's right. The CE mark (Conformite Europenne) may be self-awarded for any items that do not fall under the high-risk category (dangerous machines, pressure vessels, gas appliances, medical devices.) Most other items are self-certifiable. I was looking inside my Aguilar DB-659 yesterday and the PWB all have the CE mark on it. I doubt if Aguilar spent the $$$ to have it certified!

    www.newapproach.org has a lot of info about this (CE, not Aguilar...)

    Okay, thanks for the clarification. Power amps apparently don't fall into the self-awarded category, though, at least at the power levels we make. We have a lab do the certification testing, where they go over not only the safety of each product, but also things like AC line harmonics and RF emissions.

  11. i just got my Carvin DCM1500...i got an INCREDIBLE deal on it...it has every option i was looking for in a power amp, more over head than any person would ever need, and it's built like a tank!

    the only thing is, this sucker is HEAVY around 35 lbs
     
  12. I currently run a SVP pre-amp through a Mackie M-1400i Power amp for my larger bass rig. I think I paid about $549 from a mail order catalog from Interstate Music Supply. I am very happy with it's performance. I run this set-up through some processers, and then into two SWR cabinets: one 6 x 10" cab and one 2 x 15" . So running these two cabinets with the amp set for dual mono, and there is plenty of headroom. WOuld definitely be under your $600 budget. Good luck.
