    I am getting the Ampeg Pr410hlf, and was looking at Ampeg heads, and it showed this:
    RMS Power Output (4 Ohms): 340 x 2/1000 (mono-bridged @ 4 Ohms)
    I know that is at 4 ohms, but what does the 340 x2/1000 mono bridged mean?
    What is a good Rack compressor to get? Should I get a rack one, or a pedal?
    What head should I get with my Ampeg PR410hlf?

    I believe the description is saying that if you run the head in stereo @ 4 Ohms, it will produce 340 watts per channel (hence the x2 -> two channels, left and right.) If you run the head in mono (bridged) it will put out 1000 watts @ 4 ohms.

    How does 340 at 2 channels = 1000 watts? Can anyone suggest a good ampeg head that will/would handle the Ampeg PR410hlf (4x10) 600 watts?
  4. The answer to that question is quite technical. I don't know if you're after that. Just take their word for it that the ratings are true. I would.
  5. 1000 watt head + 600 watt cabinet = GOOD

    (same head in stereo)
    340x340 watt head + two 600 watt cabs = BAD

    It's not at all uncommon for amps to be less efficient in stereo mode. The word to remember here is- MONO!!! The head you're looking at has plenty of power to drive the single cabinet you're looking at as long as you're running the amp in MONO and don't plan on adding another cabinet.:D

  7. It's not at all uncommon that amps are LESS efficient in stereo mode!!!

    Just because an amp is capable of producing 1000 watts in mono does not mean that it will produce the equivelent in stereo mode. There are MANY reasons this might be the case. Just accept it as fact and move on.:bassist:
