Stewart 1.2 or QSC RMX 850

  1. I've been looking for a different power amp for my new cab ( SWR TRIAD ) it's a 4 ohm cab and I need an amp that will bridge into 4 ohms. At first the Stewart 1.2 looked like the answer. It is rated at like 1200 watts into 4 ohms bridged. However, others have experienced problems with thermal shut down at 4 ohms. Some have suggested leaving the upper rack space open and adding a fan. So now you have a 2 rack space amp and not a 1. The Stewart still only weighs 11 lbs but it cost around $600 bucks. (Sorry BH I'm not convinced you can deliver) The QSC is 2 rack spaces, has a fan and is only around $300 ( QSC is only rated ate 830 watts at 4 ohms continous, but, I think that is just a more realistic rating. I don't see how the Stewart could be rated at 500 watts per channel into 2 ohms and 1200 into 4ohms bridged????.) The only downfall to the QSC is weight 35lbs!!!!!. Which one would you buy.:confused:

    I paid for all my gear myself. Well, me and MasterCard.
    Stewart 1.2 vs. RMX 850 is kind of like apples vs. oranges. The RMX is an entry level conventional amp; the Stewart is a lightweight, compact amp with a switching power supply. The PLX 1202 is a closer match to the Stewart 1.2.

    The Carvin DCM series is comparable to the RMX series. The DCM 1000 is a good value, true enough, but the RMX 850 can be had cheaper and has a better warranty. The Carvin DCM series also has a reputation for being unstable when bridged into with some 4 ohm cabs (Acmes in particular). About the only thing in the Carvin's favor is that it's made in the USA.

    I use a QSC RMX 1850HD myself. Yes, it weighs 45 lbs (20 kg). But it definitely delivers the power - one channel will drive both my Low B-2s all night without a glitch, and yes, I've actually done this! And the price was right: $455 shipped from Lord Valve.

    I will eventually replace the RMX with a PLX2402, but that's in the future.

    Look at the QSC PLX 1202. Not as light as the Stewart but much lighter than the RMX
