Professional 800W 2-Channel Power Amplifier – DJ, PA & Live Sound Amp, XLR/RCA in, Speakon Out, Bridge Mode (XGA-4000)

Bought 2 of these to set up a home theater system, They work great. Have one running my subwoofers and one for my center channel currently. Planning on buying 2 more.

Sound fade in and out also sound very weak and huge sound distortion, both fans working nonstop and they are very load I mean VERY, returned my same day I tried it. feels like its defective unit but I'm sure they test them to work before production and after they make them before sending to stores (it is brand new so)

Need a power amp? We did to run our passive monitors and this amp SMOKES! Not too heavy, has a powerful fan, and the great twist connectors. I had to buy new speaker cables to connect to it, but man, does it ROCK!!!! My only "complaint" is the fan is rather loud. But, when you use it you don't hear the fan, so "no harm, no foul." I heartily recommend this amp for anyone wanting a PA amp or even a stereo amp for a sound system. Great amp and a GREAT PRICE!!!! Gemini is on my radar now concerning sound equipment. Go ahead, take the plunge. You'll be glad you did!!!! PS. Don't buy an OPEN BOX amp. I did and had to return it for a CLOSED BOX one. OPEN BOX means that something is probably suspect with that one. CLOSED BOX is the ONLY WAY to go!

The Gemini Professional 4000W 2-Channel Power Amplifier is an absolute powerhouse when it comes to raw performance. Right out of the gate, the power this amp delivers is impressive. It has plenty of headroom and easily drives speakers with authority, making it a great fit for DJ setups, live sound, or any environment where you need strong, reliable output. The sound is punchy, full, and capable of filling a room without breaking a sweat. From a performance standpoint, it definitely does what it’s designed to do—and does it well. Build quality also feels solid and durable, like it’s built to handle the demands of regular use in more high-energy environments. It gives you confidence that it can hold up in gigs or events where reliability matters. However, the main issue for me was the noise. The fan (or internal noise level) is noticeably loud, especially in quieter environments like a home studio or low-volume setting. When things are cranked up in a live situation, it’s less of a concern—but in a quiet space, it becomes very noticeable and distracting. Because of that, I ultimately had to return it. It’s just not suited for environments where low noise is important. Overall, this is a powerful, well-built amp that performs great in the right setting. If you’re using it in a loud venue or live environment, it’s a strong option. But for quiet spaces or studio use, the noise level may be a dealbreaker.

This amp arrived looking new but had a bend to one of the rack mounting sections. Unit looks to be built like a tank. I have not completely checked out full scope of sound output as yet. One of the biggest flaws so far is the two cooling fans. They are extremely LOUD. It is to the point that l'm debating returning for a refund.

Bought two of these for two seperate outdoor pa systems. Powered four 16" pyle speakers on each. Works great, tons of sound for the money. Used Audio Technica wireless mic system and for under $500 for everything, get million dollar sound.

I purchased two of these. One to drive my loudspeakers and one for my subwoofers. Better Amps are available but not at this price. These have all the connection ports you should need. Setup and configuration is quite basic. The hardest task was to hi-lite the English parts of the multi-language user manual.

We remodeled our home and is just now moving back in. We’re just now opening the boxes and see that the amp is not working. No lights coming on…no nothing!!!!!!! My fault….. lesson learned. NEVER AGAIN!!!!!!!

Perfetto molto potente direi voto massimo

Der Lüfter ist selbst bei geringster Leistungsabgabe sehr laut. Betreibe das Gerät im Garten und man kann sich im Umkreis von 2 m kaum unterhalten. Ausserdem war ein Schaden am Montagewinkel (verbogen). Ansonsten funktioniert die Endstufe einwandfrei.

It's a bit Lound with the fans running but makes up for it with the power and good sound but dose sound better with an older mixer pre health and safety 😉

Good Products but have not started using.

J'ai racheté sachant que j'avais le même
