Which Poweramp for Tech 21 RBI

Discussion in 'Amps and Cabs [BG]' started by him666, Nov 16, 2005.

  1. I have an 8 Ohm Aguilar GS212 600 watts. And a Tech 21 RBI which i use for overdrive, but i would like to use it as pre-amp. Any advice on a poweramp?
    Which one are you using?

    I live in Europe (220V).

  3. The QSC PLX1602 gets my vote, too! That's what I use with my RBI. I use it to power my Tech 21 410 & 115 cabinets. You can't go wrong with the PLX series.
  4. For a little less money than the PLX I bought a Crown CE 1000 that's worked fine with my RBI for a couple of years now.900 watts at 8 ohms bridged and about ten pounds heavier than a PLX.

    It's not special materials that make the transformer lighter; it's that the transformer is operating with AC at 110 kHz, so it can be a lot smaller and still be able to transfer a given amount of power compared to 50 or 60 Hz.

    I used a carvin DCM2000. The worst thing about it was the weight. Weighs 38ish pounds in a 3 rack spaces. I like it though.

    Thank you. Changed my original post. I learned something new.

    I use a Stewart World 2.1. Tons of watts, 17 pounds.

    I love the fact that it's dual monaural: each channel has its own power supply. It's like having two separate amps in one 2-space box... I often use just one channel and leave the other powered off as backup.

    What is your budget?

    I currently own about 5 power amps for various tasks (bass and PA).

    I've been happy with all of them:

    - Stewart World 2.1
    - Peavey DPC 1400X
    - Stewart PA-200B
    - Carvin F600
    - QSC USA 850 (old school!)
  11. I'm using a Stewart World 1.6 with the RBI, into a Schroeder 4x10. LOUD. Did I say loud? Also, clean, clear, punchy, gritty, glassy.. I'm running out of adjectives. Anyway, I really like the Stewart/RBI combo.

    Wow. That's really cool.

    So, what made you (all) go the power/pre route instead of the "traditional" head route?
  14. I wanted more power than was available in a traditional head. My pre/power set-up cost considerably less than a lot of standalone heads, and I've got way more headroom than I'll ever need.
