like the other reviews state... there is no audio cut off. if a standard volume knob goes from zero(nothing) to ten (max volume), when you turn the volume knob to zero its actually letting through sound like its at a 2. its pretty bizarre. other than that its great. ART needs to fix that and id give it 4 stars.

The Art powerMix III does not work. It arrived with something wrong in the AC DC power adapter. We tried a lot but we never could be turned it on. The green light never brights. This should not happen very often with the technology and equipment made ​​in China. Unfortunately this time the unlucky touched myself and I received this product with factory problems.

Can be difficult to set up with multiple devices and get the sound balance correct.

I use this mixer to run an ASUS Xonar D/A, my laptop audio and my TV line out through to my Klipsch Pro M221 powered speakers. There aren't very many small reasonably priced mixers to use for a consumer audio application like this, and after a bad experience with a Rolls MX41b, I decided to give the ART a try even though it seemed more oriented towards pro audio/stage applications.This is a high quality unit, which is what I would expect from prior experiences I have with ART products. Solid and heavy enough -- which is important so all the cables don't make it tilt or fall off the edge of a desk or other box when stacked. All the controls have a good smooth feel and allow easy very fine adjustments. Not a bad looking box, so it can sit on the desk without looking ugly or out of place, although it has the labels for the inputs/outputs printed on the top and very visible.This is a very clean mixer -- no noise or distortion is added until the levels are totally maxed out, which is silly to do anyway. But at ~50-75% levels the signals are clean and strong enough to satisfy the Klipsch and sound great.It only has 3 stereo input channels, but that was enough for me. Some of the other small mixers out there are 4 channel.I like the individual line and headphone volume controls, as well as the individual pans for each input (although I really don't need to pan each one individually -- in my set up I just need one pan to slightly adjust the output to compensate for my speaker placement, but it could be very handy if the inputs are biased towards one channel).The biggest complaint for me is that at 0% levels the signals are not fully muted, and there is no separate mute switch per channel like on a pro mixer. So, if I have the TV on but want to listen to music through the Xonar, the sound from the TV faintly leaks through, which is insanely annoying during the quiet musical passages. This is a stupid flaw on their part -- either 0% on the levels should be fully off, or there should be a separate mute switch. For the computer audio, I can use the software mute control, but I'm going to need to find some other way to mute the TV since the line out does not mute via the TV controls (arguably a flaw on my Samsung TV).A small minus is the lack of a power switch, so it remains on all the time. It doesn't seem to draw much power and doesn't even get slightly warm, so as long as being on all the time doesn't reduce it's lifetime, I guess it's not a big deal.One other minor complaint is that all the inputs/outputs are 1/4 inch plugs, 1 per channel. I know this is standard in the pro audio world which is where ART typically plays, but it's of course not common for consumer audio. It would have been nice to provide either 3.5 mm stereo or dual RCA inputs/outputs as well, so I didn't have to buy a bunch of specialized pro audio cables (3.5 mm to 1/4 inch, and RCA to 1/4 inch).So, overall a pretty good rating from me. I really can't say 5 stars "I love it" due to the lack of muting issue, but certainly 4 stars for overall performance and quality.

I bought this for rehearsing, and have used it for a little over an hour at the time of this review. I like to mix my laptop with my instruments, so I can play along with backing tracks, etc. It works really well for this purpose. I don't plan to travel with it, but the metal case seems to be ruggedly built. The ability to pan the various channels made the stereo version of this mixer worth the extra cost for me. If you don't need stereo, consider the less expensive mono version from ART.The AC adapter has a flimsy cord, which is typical of many gadgets these days. This unit has some quirks, and for the money I'm a tiny bit disappointed. There is no on/off switch. I use it with a power strip that has a toggle switch so it's not the end of the world, just a little annoying. It also doesn't have a pad selector (-db) or a ground lift. No huge losses there, but would have been nice to have some of these obvious features. As another reviewer pointed out, even with all the volume pots turned all the way down, some audio signal still leaks through. Without a mute button on any of the channels, this might be a problem for some folks.Happily, I have not noticed any noise or humming from it and the sound quality is MUCH better than other cheap little personal mixers I have tried in the past from other manufacturers. Overall I'm satisfied with it so far, and plan to get a lot of use out of it.

I got this to connect a computer and a music player to an amplifier to drive a single set of speakers, so I could listen to music, but also hear the audio from my computer, either for little things like alerts while music is playing, or for videos or music played on the computer (probably while the other is paused). But mostly I didn't want to switch between them.I read a lot of reviews of other similar products which said that the result was unusably quiet.The ART 3 channel mixer had no issues with that. It worked just great for me. The only thing I'd want to fix on it is that the knobs aren't labeled on the front, only the top (which I can't see in my setup). So, I'll apply some labels. Also beware that it uses mono headphone-type 1/4" plugs, 2 for each channel. I knew this so I ordered the appropriate adapters, but that adds about a quarter of the cost of the mixer to the over all price.Individual level controls allow you to specify how much of each channel goes into the output. Then the master volume dial allows you to specify the speaker volume without messing with the levels. I have a volume control on my amplifier, but I use the volume on the mixer because it's more accessible.This mixer easily met my expectations.
