Rockville RPM45 1800w Powered 4-Channel Mixer Amplifier, USB, Effects, Phantom Power, Durable Wooden Enclosure, Compact Design, for Musicians and Small Venues

Been using this for over three years now and it serves its Purpose. Hasnt shut down or quit on me yet.

My old Peavy mixer amp died, and, given the amazing price and good reviews, it seemed worth giving the Rockville product a try. I am beyond pleased. It does more than my old Peavy mixer amp did and is just right for a small band. I didn't realize that an MP3 player was included. The player is excellent, with easy controls. The unit is light and easy to handle. Just finished our first small performance and it was a breeze. The audience seemed to like the sound too!

One channel was not putting out power. I think they asked for 3 bucks to ship it back hassle free. We ended up finding out the 1/4 in output jack was loose. Righty Tighty Easy Peasy fix. Works great for Drum Machine and vocals in a small 20x20 studio.

Dynamic microphones 🎤 pair well, haven't used condenser mic with phantom power, seems to be made well, meets my needs, at price point. Good quick shipping.

I used this amp as a backup for a DJ gig. It was very loud and crystal clear. No distortion. Although tone controls are rudimentary they are more than adequate for the job. I was very impressed. You can load a boat lid into of songs onto memory stick and just plug it in.

Very impressed

I am unsure what the other reviews were about when they stated the fan was loud. The fan is no louder than the fans on any other amps I own. Other than that point, I did a complete test run of the amp, and everything checks out just fine. The test was done in the room where I intent to use it and that is about 12’ by 12’. The test was done with my old Panasonic near field stage monitors which is what I will be using with the amp. Everything seems fine. Backing tracks played well, but the only issue I had was with my Very Old Fender Strat which seemed a little low and had to raise the volume a bit (Might need to bring it into the shop to get checked out). All my other guitars and my wireless microphones seemed just fine, even my acoustic/electrics played well. Satisfied with the purchase for a practice amp, would never use for live performance - does not have the power for that. I have several other amps for that purpose.

I was looking for a little stereo rig to play my drums to, so it had to be fairly loud. I got one of those mini amps that claimed to put out 120 watts, but sounded more like 40 watts max. The thing was so small and light that the weight of a cord could drag it off the table. It was just under $60 so i decided to upgrade a bit. I saw this unit for only $50 more, with astronomical power ratings, so i went for it.About the power output, it is ridiculously exaggerated. A 2400 watt amp would be way bigger just to accomodate the transformers and would need some serious fans to dissipate heat. This amp is not close to that wattage. Even by their own figures it pushes 225 watts RMS per channel. That is still substantial. They multiply that 225 watts x 4 channels and claim 900 watts. Sorry, 225 watts per channel is still 225 watts. Going a step farther., they double the supposed 900 watts RMS to arrive at a peak wattage of 1800 amps. Peak wattage is then given as rms, which is baloney. Peak wattage is not a real thing and not worth mentioning. Even if those figures panned out it would still be less that the 2400 watts they claim, so I dont know where that figure comes from.This little amp is loud but nothing like a 225 watt amp should be. I have played in bands all my life and have owned and played on many different amps, and I can tell you that any 100 watt guitar amp is twice as loud as this thing. This amp would be hard pressed to cut through the noise at a busy club. If you turn the master volume past about 3/4 full it distorts pretty bad (which is true of about any solid state amp), so the effective range of use is comparable to about a 50 watt amp. The cabinet is sturdy and looks nice, but the tiny knobs are a big drawback. At least the master knob should be bigger than the other knobs. Plus all of the knobs are identical and the labels so tiny you cant see them. Look at the panel labeling on quality amps. It is concise and legible, not so on this unit.The tone controls dont have much range, but work to trim the highs and lows. Im running it through a roland 200 watt 4x12 cabinet and the sound is ok but a little muddy. The aux channel functions at a much lower volume than the main channels, but i have used the aux output along with a 15 watt pre amp to power a small monitor.But I dont mean to be over critical, because its a great amp for the money. Just dont expect anything close to the wattage ratings given and beware that adjusting it while playing is difficult unless you have the knob locations memorized
