It performs well, but there's a slight rumble from the .

Only used a few times as a two channel amplifier. It performs well but there is a little hum coming from the speakers, but what do you expect for the price? The fans are a little noisy and the blue power indicator is a little bright, but not as bad as other reviews suggest. So far it has been satisfactory but not impressive.

Pros
  • Home Audio
Cons
  • Protection

Only used a couple of times as a two channel amp. It performs well but there is a little hum coming from the speakers, but what do you expect for the price?

Pros
  • 2 x 500w @ 8 ohms / 2 x 1000w @ 4 ohms
Cons

Don't let the brand fool you.

This amp is a real gem. Made in the USA with the same components as the big brand amps. This kid will not disappoint you. It beats without the price tag on the brand sticker. I have this amp with a pair of SA-155Ts and they drive with precision. Seismic Audio is a brand you can trust and their customer support is top notch. If you ever get the chance to buy this amp, do it. They are difficult to keep in stock, which alone makes them worth buying. I use it for my mobile DJ setup.

Pros
  • Instant peak power of 4000W into a 4 ohm bridge
Cons
  • Not as thick as other picks

Reliable, accurate performance Value for money

Big disappointment. Useful but overdone features. 2 x 200 watts at 8 ohms at best. The power switch has failed in the on position. The fan is loud. And while it didn't factor into the rankings, I agree with others that the DISHINGELL blue LED is bright. The claim of dropping to 20Hz is ridiculous. The rolloff starts at 45Hz, with -10dB at 35Hz and a dead end at 20Hz. I will use it but replace in the near future. ***Update 28 February 2017*** This unit has been replaced with a pair of Behringer…

Pros
  • Model number: MBG-4000 Power amplifier
Cons
  • Communication with seller

I was very pleased with the feel and weight

This is the first review I have ever written on Revain and also the most disappointing product I have purchased from this site. When I received this amp I was very happy with the feel and weight. This, along with the online reviews, led me to believe I was expecting a real treat. This amp was purchased with Seismic Audio SA-15T PA speakers rated at 350 RMS and 700 Max. I figured a 500W RMS amp into 8 ohms would have enough power to drive the speakers to allow the speakers to reach their full…

Pros
  • Brand new - one year warranty
Cons
  • Lots of stuff
