Sound Town 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.

1st one came damaged and non-functional but was quickly replaced with a new one that worked as advertised.

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.

Only 2 channel play. I've tried every change possible to try get channel 3-4 to function. Very disappointed in false claims 600 Watts rms power to 4 separate channels with only 2 operational and those sound great but have not put my speakers to workout more like typical 100 watt reciever output. I should have known better when its too good to be true, its usually too good to be true!! returning amp! Amp was returned and accepted on Feb 26th, have talked to Amazon bout refund first told will take few days, then earlier this morning told I'd have refund in next hour or two, then the return page went from returned to asking if I want to return item again and what is my reason. Next phone call to customer service says I won't get refund until almost end of March. AMAZON has become a shady company to shop with!!

Quiet and no hum. Lots of power and has been rock solid. So far, good performance and value for the bucks.

So so

It has no good sound

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.
