Review: NEW Update Nov 7 2023. I wish I would have bought at least 2 of this model and at least one of the 4 channel.I'm currently powering a set of 2000 watt Titatan z's and they sound incredible! UPDATE 1 year and still PUMPINGI would highly recommend this Sound Town ST-UPDM7500,after 7 month's and at least 50-60 4 to 6 hour shows/jam sessions it's still going strong. It's driving 2 Wharfedale 12in. Titan Z's. 500w RMs 2000 watt peak mains on 1 side and 2 700 watt peavey Impulse 10's on the other.It is incredibly loud and clear.To keep your amp safe from pop's and spikes and working properly remember your Amp should always be L.O.F.O. " last on first off ".
Review: Just used the updm 7500 to push my 2 celestion ftr18-4080fd 8 ohm subs. These are 1000 watt each..I needed an amp to get me through the weekend. Though this amp was only 950 a side at 8 ohms. It performed flawlessly through 2 nights over 4 hours each. Never got hot..never clipped..never shut off. Was quite surprised with this amp and very pleased.

## Questions & Answers

**Q: Would this amp be a good match for 4 mr. dj pro115s speakers?**
A: This amp drives 1700watts @4Ohm and 950wats @8Ohm. So check with your speaker impedance carefully.

**Q: I have 1000 watts  8 ohm monitor this good .**
A: Yes.  You have to be a bit careful because this amp is powerful.  I popped a tweeter on one of my 800W monitors because of a dropped microphone.

**Q: If this amplifier uses 15 amps at 110V, which is 1650 watts, how it is capable of putting out 2 channels audio at 1700 watts each? Not possible.**
A: @ 4Ohms it does put out 1700 watts on a 30 amp circuit. I tested it myself. I called BS on the specs but bought it anyway and tested it.

**Q: Can i use all channels independently? i know it sounds stupid but i want to be sure? is the fan noisy?**
A: Dear customer, 

There is no stupid questions! And yes, you can use all channels independently. 

As this is not a traditional class-AB amplifier, the amp overall is much quieter. 

Feel free to let us know if you have any additional questions. 

Thank you,

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.
