Gemini GPA-2500 3000W Professional DJ Power Amplifier

Solid, simple, and just as advertised. Had them unboxed and working in 15 minutes. Controls are easily accessible and feel right. Now, endurance will be the key. Will update as they age, but I don't see any worries. Thanks Gemini. 7/20/2020 Update. Very solid and very reliable. Keep in mind it is 2000 W peak not 3000 W like in the description. They serve me well. As my system grew, I needed to upgrade but these drive my monitors with lots of room left. For the price, I am very satisfied in every way.

Good cheap amp

Amp was good out of the box. No problem with it. Produced a slight hum, but did not notice it in a noisy enviroment.

I do DJ work on the side, and this amplifier work great.

Just temper your expectations... I'm sure this'd be great in a club or something, but if you're looking for sound quality and functionality, maybe look somewhere else. There is a serious buzz at anything over level 3 on the volume knob. Without even turning it on, my speaker started humming when I plugged in the XLR input... Hum was counterintuitively better when using an unbalanced TS cable, but still significant when turned on and up. And all this says nothing of the cooling fans... Yes, the cooling fans are LOUD like the other reviewers say. Like server cabinet loud. And there is no fan speed control so you can't even turn down the fans when playing at lower volume at home. Does it drive speakers? Sure! Loudly! And, when you're playing loud music in a club or at a noisy bar or something, I'm sure the speaker buzz and cooling fan noise would be insignificant by comparison, no problem, but do not expect to use this at home for casual quieter listening. I'm using it to drive a 1000W 18" subwoofer and it does the job! But, I'm regretting not getting an amp with a built-in crossover or LPF. I probably should have gotten a quieter, lower wattage amplifier with more features to better meet my use case, but ya live and ya learn...

When you get this, you should look at the specs, I bought a GPA 5000 and I made sure to read everything. I use mine at eight ohms not 4 ohms at four, I get 1600 W at higher at lesser ohms, at eight ohms I get 800 watts and that’s what I prefer is eight . But if you start Daisy Chan, you put more strain on the amplifier with more speakers. If you parallel the connection you’ll stay closer to 6 to 8 and less stress on the amplifier and if you stack too many 4 ohm speakers you’ll fry the amplifier. So I used no more than 4 two way speakers 15 inch two way PAs passive and she played beautiful with no strain. You’ve got to be careful when you daisychain your connections. It’s better to parallel connect them, especially on these amplifiers and your home was probably from a poor ground. Did you flip the switch in the back that will kind of float the ground. But for the money you cannot beat these amplifiers I had an OSD preamp also using a technical pro Bluetooth receiver. I also added a 30 band equalizer for other principles and purposes. But I preferred the osd pre 1 it worked the best. Always be sure you’re ground is true. The only problem I had was I had a defective power switch. I went to the store and paid seven bucks for another and that’s the only problem I had you got to be careful because these are assembled in China and a lot of these people quotas to make so they don’t always finish assembling the wires. I’ve talked to many people and like me they were able to fix it. Always check your stuff out first before you plug it in anything made in China is about quantity not quality that’s why I hate China when it comes to sound systems. I hope this helps you and understanding.

This thing is POS.. Do not buy it. It does not hold up to anything. This is my second one and it left me without a sub for a gig. I was so pissed... It just stopped working for absolutely no reason. I turned it on like any other time and then all of the lights came on and the fans were at full power. Nothing came out, started smelling something burning. Everything was hooked up right, everything was turned down and everything was ready to go. This thing just decided to not do anything but sit there like a paper weight. I only use it for my sub as everything else is powered. I couldn't believe it. I could have bought an old technic amp that would have done better. This is a piece of crap, do NOT waste your money, do NOT listen to anyone else. I didn't even want to send it back, I just tossed it in the trash and bought a powered sub.. This thing is a ripoff and is no where NEAR on par for any DJ... DO NOT BUY THIS CRAP!!

Greatest

el amplificador tiene una electrònica muy bàsica, su potencia es de por lo MUCHO 200 W por canal.

Works pretty good, but lots of noise from the fan.

Great for its price a bit noisy from the fan but the longer it's on the fan does runs a Lil quieter but in all I'm ok with it
