Compact quality amplifier, great for smaller installation. The ability to lock out the gain controls with the included blanking panel is a nice feature as well.

I know there are hundreds of bass players who use a Tech21 SansAmp or similar to improve their sound. If you do you are are likely inserting it between your bass and a typical bass guitar amp..

I am rebuilding the AV system for a small congregation and I needed an amp to replace a cheap one mounted underneath the podium. I chose this one because of the whisper quiet fans so that I would not have to rewire all the speaker cables by placing the amp in the back.

In it's first use, in a dark club powering a couple Marshall 4x12's, it was tremendous. But I live in an apartment with thin walls, and don't run high levels, much less even own a guitar amp. When I powered the amp at my home workstation with vintage NFM's, I was like, "Oh no!

I had called Sweetwater to inquier about a similar power amp and my rep suggested this one. (Thanks TJ) The other amp had a fan (A little noisy for a controll room) and this one doesn't. I'm using it to power an old pair of NS10's. It's clean and quiet!

I provide audio visual to companies and was tired of hauling a ton of equipment.Thinking outside the box, and with the help of the Sweetwater staff, I bought the ART-SLA-2 to be a single space amp to provide power to my 4 space rack.

This is a conventional sled amp in a 1U package. I use it for bass guitar. Couldn't ask for a better sound. It goes very deep, but still sounds tight -- the hallmark of a well-designed Class AB amp with a traditional (non-switching) power supply.

I purchased this amp to monitor my vocals/instrumentation in a live environment. I know this amp in descriptively intended to use in a studio environment but I needed a powerful 1U amp and thought I'd give it a try.

Great little amp. It powers 4 Ohm speakers effortlessly. Unfortunately, since I was using this nearfield, I could readily hear significant transformer hum during quiet passages or no music output. So, the black background isn't as black even as some midfi stuff.

Bang for the buck, awesome. We bought one for the office boardroom speakers - liked its reliability and low noise so much I added one to my studio to drive my Avantone secondary mix monitors. Whisper quiet, easy as it can get. Only takes one rack space.
