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. Review: Good Buy - 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. ## Features - ULTRA-EFFICIENT UPDM POWER: Leveraging Unipolar Pulse Density Modulation (UPDM) technology, this amplifier delivers massive power with ultra-low energy consumption - HIGH-OUTPUT PERFORMANCE: 4 x 800W RMS at 8-Ohm Stereo, 4 x 1520W RMS at 4-Ohm Stereo, 2 x 2100W RMS at 8-Ohm bridge - FLEXIBLE OPERATING MODES: Easily switch between Stereo, Parallel, and Bridge modes to perfectly match your system's power and channel requirements. - PRECISE INPUT MATCHING: Selectable input sensitivity (0.77V / 1.0V / 1.44V) ensures optimal signal levels from source devices.

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.

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. ## Frequently Bought Together - Sound Town Ultra-Lightweight 1U 4-Channel PA/DJ Power Amplifier, 4 x 1400W at 4-ohm, Supports 2, 4 & 8-ohm (ST-UPDM4C) - GearIT XLR Microphone Cable (10 Feet, 10-Pack) - XLR Male to Female, Balanced Shielded Cable for Mic Mixer, Recording Studio, Podcast - Black, 10ft, 10 Pack - Yuyaokk 2Pack 100 ft Speakon to 1/4" Male Speaker Cables, Professional 12 Gauge AWG Wire Audio Amplifier Connection Cord, DJ/PA Speaker Cable Wire with Twist Lock. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/154757097-ultra-lightweight-1u-4-channel-pa-dj-power-amplifier-4](https://www.desertcart.tn/products/154757097-ultra-lightweight-1u-4-channel-pa-dj-power-amplifier-4) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-15*
