Gemini Sound XGA-4000 Class AB 2X 350W Pro-Grade DJ Amplifier - Rack Mount Powered Mixer Amplifier for Live Sound, Ideal for Mobile Rigs & Venue Setups

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 😉

Excellent value for a low cost amp

less power than i taught. 4000 W does not mean 2000 W per Chanel as i taught. Maybe i am naive so my opinion may be a bit too harch

Great

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.

Good Products but have not started using.

J'ai racheté sachant que j'avais le même

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.

Finally had a chance to hook up and listen to this amp at my home studio (2 days now, continuous) and found the sound amazingly linear all throughout the frequencies and genres (classics to rock of all sorts of flavor) of music. Sound reproduction well defined, crisp, very clean and powerfully responsive all throughout the frequencies, well focused as required by the score. Power of this, I feel can handle a fairly large venue, though not yet tested at a live gig and observations have been limited so far to 3.2 max on the dial, stereo mode, on both channels 1&2, as any more would simply be too loud for my studio room. In a nut shell, just from my listening perspective, what I particularly like include: 1. musical instruments reproduction-separation is very distinctly crisp, balanced and clear (heavy full orch. music from classical like Beethoven's 5th to rock live performances, like Sting's in Berlin) from base to percussion; 2. distortion level is virtually un-discernible, at least to my ears, and high fidelity sound quality is simply impressive for an amp of this price.. would even say that it sounds like its almost there, leastwise, with amps priced at 4x.. 3. highs, metal sounds like cymbals, and even guitar finger squeaks, mids like vocal jazz modulations, and bass from picked bass guitar to fret less acoustics, and even the type of piano being played, are clearly reproduced-heard, from whisper level decrescendos to very strong crescendos, with enough depth and power, as needed.. simply brings any piece to life. What I don't like: 1. the significant noise generated by the cooling fans -- it has four (4) internal fans that are running at constant mid speeds and producing 69.0 dBA (max, 56.0 ave. with sound meter 3 ft. away from the unit). So for my initial use in the studio, I've kept the unit almost completely walled in by acoustic foam boards, and inside a sound cancelling cabinet to be studio use-able. As permanent solution to the fan noise issue, my intent is to add a temperature based fan speed control unit, so I can adjust fan speed curve vs. temperature thresholds, and reduce the noise to audio acceptable levels for studio use.. Otherwise, my guess is, in a live-performance situation, the ambient noise would pretty much cancel out the amp's fan noise. Even with the fan noise, notwithstanding, this amp I believe, still represents a great buy with its very impressive cost effective performance.
