    I bought this as a replacement for our churches sound board. I added wireless microphones and combined they work very well. We have only used it once so far, but Sunday's coming and it will get another run.

    4.0 out of 5 stars A decent practice amp.

    P. · July 12, 2020

    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.

    5.0 out of 5 stars Worked Awesome for 5 piece small band...

    T.G. · September 5, 2020

    Worked Awesome for 5 piece small band... Very powerfull little amp. We plugged in an 8 channel mixer and was able to handle 5 instruments and 3 singers no problem. First use out of the box it was on medium volume (as load as we all could deal with in the space we were in) for 6 hours of practice and did not even get warm to the touch...Not sure how it's longevity will be but I think as long as we don't over tax it, it should last for a good long time (I hope) we shall see... It seems very rugged and the material it's covered with seems thick and looks as though it could take a beating and keep on going but again that probably will have more to do with how it's taken care of. All in all I would recommend this for an inexpensive alternative for a small get together or small band situation...Cheers All...

    5.0 out of 5 stars Better than I thought. Fan noise is bearable. Sturdy

    I hesitated a lot before I made a decision to buy this mixer because there were a lot of complaints about the fan noise. I also considered Pyle but I ended up buying Rockville, a used (very good) one. I was able to confirm that the fan noise was very loud, but I do not know if this is louder than its competitors, but if you want to use it in a small space, this noise would be a problem and I do not recommend it. But if you are going to use it in an open space or in a large space, this level of fan noise would not matter much. The design is simple and it functions well. I think this mixer is quite solid. I also have a pair of Rockville Passive Speakers (12 inch), and this mixer works very well with the speakers.

    5.0 out of 5 stars For the price it is great.

    3.0 out of 5 stars 1800 watts? i dont think so

    R. · March 16, 2021

    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

    excellent

    been working perfect since I got it

    Very Impressive for the price - (please note technical observations and provided picture)

    This is a MONO system with two outputs in parallel (Not Stereo - Not two output amps) I tested it with two completely different USB sound tracks. Both tracks came mixed equally on both speaker outputs.Did not function well at 4ohms load created by an 8ohm speaker in each output -the overload protection cut in at halfway on the master volume. (The peak power rating of 2400 is not realistic)It works with beautiful sound on 8 or 16 ohms using only one output connection or 4 speakers in parallel/series config.Crystal clear and about 200w usable power (run it up to 75% full volume with no problem with 140w speakers)

    not even close to the claimed power rating

    N.R. · October 16, 2019

    Control pots seem to have no backing and to be mounted directly on the pc board and and gives a flimsy, not secure feel. Otherwise, functions ok.

    Loud fan!!!! Works well otherwise

    J.R.V. · November 19, 2019

    Replaced my small church pa with this. Works well except for the overly loud fan that runs continuously? Design flaw for sure!

    Fan is loud

    D.B. · December 16, 2019

    Works great easy to set up. Impedance with speakers was tricky at first and fan is quite loud.
