Peavey Minimega Power unexpected low output

    Hello guys, well I recently bought a Minimega and hooked it up to my Headliner 410 8ohm Cab. The amp sounds great, but I was dissapointed with the power output (which should be 700w @ 8ohm). I thought it would be much louder.

    I decided to put my old Laney RB6 165W amp and test it next to the minimega (side by side), putting them both at 5 they sound the same. I would expect the Minimega to be 4 times louder than the Laney combo amp, but this isn't the case.

    By the way I am connecting the minimega to the cabinet via a 10 gauge speakon cable.

    Anyone Minimega owners can feedback on this please?
  2. Return immediately and get a replacement. There have some problem units. Peavey will most likely repair or replace if you can't just return it to whom you bought it. This amp is KILLING loud at 4 ohms. I only run 8 ohms at low volume gigs. Still it should be significantly louder than your combo.
    As to "it should be 4 times as loud" that's not how the math works out.

    Knob position and volume will never match from amp to amp across brands or even models. Perhaps this might account for the difference?

  4. As always, from the horses mouth...... I believe the knobs are useable throughout their range. Don't be afraid to turn them.
    Try starting all knobs at noon except this, try gain 9-12 and master 12-2 or more, also try hitting the Punch button, it gives a low mid kick. I've run mine through a Bergantino Ex112 8 ohm and its loud enough to gig with a drummer that's reasonable.
    Also music styles play into all this, what are you trying to sound like? What do you play?
  5. There is not a linear relationship between power output and how loud something sounds.
    Your ears don't do things that way.

    If you could use the same speakers (assuming they could handle the power) you would need to increase power roughly ten times for the bigger amp to sound about twice as loud as the small one.

    Still, I would expect your new amp to sound a little louder than the old one. That is if the power of both amps are measured and rated the same way.

    If you really want to get more bang for your buck, adding speakers (while keeping within the impedance rating of the amp) is the way to go. Doubling up on speakers will get you in the vacinity of sounding twice as loud.
