Ultra-Lightweight 1U 4-Channel PA/DJ Power Amplifier, 4 x 1400W at 4-ohm, Supports 2, 4 & 8-ohm (ST-UPDM4C)

I run a small sound company that does about 15 concerts and festivals a year. I have to run sound in a 360 degree setup which can be challenging. I use this amp to power 4 -12" two way Mackies, covering about 500 people, and it has performed excellently. I received more complements on my sound this year, than any of the past 20 years. I used it all year, pushed more than my previous amp (QSC) and it performed better. I am able to send individual signals to each speaker and control the sound much better. It only takes up one rack space and is very lightweight. I will probably buy another one very soon.

I was looking for an option to run passive speakers when I didn't have my actives with me, as well as more than 2 channels. This amp has plenty of power over 4 channels. I would buy it again, if I needed to.

I am a pro audio professional. I work with bands and DJs. I know that sound town is not really a respected “pro” brand. It’s kind of “cheapo”. Like Gemini or American DJ or something like that. But… I just needed something in my little test rack that i keep just inside my garage door so I could plug in and quickly test speakers as they came back from each gig. It didn’t have to be great. It just had to work. I have to say, that I am actually very impressed with how this amplifier sounds, considering how small it is, and how reliable it has been so far. I use it for testing everything from subwoofers to stage monitors to full range speakers. I even use it to test out active three-way larger PA speakers so each channel is doing a separate frequency range, I.e. external sub channel 1, lows ch2, mids ch3, highs ch4. Not only does it do all of this without any issues, but it seems to be loud as hell with plenty of headroom. I haven’t taken this to a gig, because I use QSC and Powersoft for the real gigs, but this little amp is worth a look if you are a small DJ or band on a budget. It’s actually hard to believe how much output this thing has while still being small enough to put in a backpack. Amazing.

I've used amplifiers from Peavey CS1200X to the fancy 1 RU "Italian" Powersoft digam series. I've been a DJ for over 20 years and I have to say that this little unknown amplifier holds its own. Currently for my small DJ rig I'm running 4 passive QSC AD 8t that I modified to fit on stands and I also run 2, modified 10 inch Meyer Subwoofers off of 1-4 channel Amp. I have a small DSP to cross over the frequencies going to the Amp. This Amp is extremely powerful. I had my doubts in the beginning but I'm very glad I bought this unit. Getting ready to buy more for my bigger systems.

Este producto apenas lo e usado 3 veces y no me gusta por qué después de una hora empieza a holer a quemado y se baja el volumen

Positives: - 4X1400W, weighs less than 10 lbs, and only takes up a single rack space - amazing! - I own a Behringer NX4-6000 that I use to run our mains (I'm using the Sound Town amp to power our monitors). It is rated at 1600W per channel. When comparing them side-by-side, my assessment is that the sound output of one Soundtown power amp channel is equal to one Behringer power amp channel Negatives: - The knobs are really small. I painted them white to see them on a dark stage - You can't bridge the channels together - Too new to judge durability. But I've had two Behringer NX4-6000 unit fails is less than three years, so I took a chance that the Sound Town power amp will de better. Too early to tell, but I've used it for 2 gigs now, so far so good

I had it for a few months and it’s worked great. Now it’s started making a loud fan noise that makes it unusable. I’m reaching out to sound town. Will update if I get help.

Sounds absolutely awesome lots of power it allows me to truly bring the volume and Color out of my Cerwin Vegas XLS 12s & ELACs I ABSOLUTELY CAN FEEL MY MUSIC THE WAY I LIKE IT LOUD!! No more constantly feeling my amp to make sure it’s getting too hot! Only one small thing I wish the gain dials were just a little larger otherwise COMPLETELY SATISFIED!!😉👌👍

Sueña muy bien los probé con unas Yamaha y se escuchan muy bie lo único es que al subirle se baja la luz eléctrica de la casa pero Es muy potente

I purchased this AMP after my Behringer iNuke 6000 stop working after only 5 short years. Also wanted a change from my old Nikko and Peavey AMPs. Never heard of Sound Town amp but decided to give it a go. Folks that little thing have some sting. I call it the "Scorpion". Small but its punch is deadly. It has brought my system alive. I am running it with some Bose 901 latest series V2, also tried it with some JBLs and some custom-build that I made some years ago. The clarity is clearly noticeable. Great sound through the entire music spectrum. I am about to purchase #2.
