What is Demo Gear?

At Sweetwater, we're so picky that what we call a "demo" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

What demo means to us is that we've had it out of the box, or maybe it was in a customer's hands for a few days and isn't "factory fresh" as a result. Every demo item we sell has Sweetwater's 2-year Total Confidence Coverage™ warranty, and has been tested and verified up to "new" specs by our factory-authorized technicians to make sure it's in perfect working order before we ship it to you.

When you buy a Demo item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!

very useful and reliable compact line level mixer

I paid $ new for the ART Power Mix III so that should tell you how long I've been using it. Audio purists will point out its slight crosstalk and also bleed-through but I believe it was meant for simple line level mixing and monitoring while working out ideas not master recording mixing. I'd buy another if necessary at today's price but might also consider the ROLLS MX-4.

Simple, versatile, quiet, easy, budget solution

After using this for three years, I have found it VERY useful for a number of applications.

It is great for mixing three distinct audio sources in a solo performance rig. You can connect an audio source ( CD player, MP3 player, etc.) in STEREO AND connect the outputs from your multi-effects guitar preamp to another channel. That let’s you hear the background tracks you play with as you perform. Most audio sources use 1/4 cables. This accepts those so you don’t have to buy more expensive options.

(If you have patch-bay TRS cables, those work too!)

It is clean and quiet enough to use in the studio whenever you run out of channels on your main mixer. You can sum stereo toms or whole drum sets, guitar, mix-room and direct mics or keyboards to record all of those on a single track.

Yes, when you do that you must mix carefully by ear. So, without the benefit of metering, we are forced to listen and learn to mix. Those trained only to use software mixing or metered mixing will be unhappy at first if they have not yet developed sufficient listening skills.

The same thing holds true for setting levels. You must start in the middle and turn DOWN (first) or UP (second) as needed. It is not like a fader-based mixer where everything starts at zero (infinite attenuation) and then gets louder (towards unity-gain.)

I can easily see how someone who does not understand those basic principles of analog audio might not like this product. That said, here are a few more uses where this tool excels!

ANY live rig with multiple stereo sources where lightweight and small size is crucial.

ANY studio set-up that requires two or more stereo sources to be summed at similar levels ( pre-mix.)

ANY mobile broadcast set-up with multiple sources where easy transport is important.

Level-balancing TWO or more stereo sources into one amp (acoustic guitars+ electric + keyboard + recorded tracks, etc.)

Summing to mono for phase coherency.

Checking for phase coherence via summing ( and listening for dropouts.)

Mixing two detuned synths for dramatic PHAT tones!

You can use this creatively with multiple sources for sci-fi sound effects, inter-modulated synths, intentionally creating flanging with time based modulation (even if you don’t have a flanging pedal!)

Audibly checking cables for dropouts and tone balance.

If you need a mic-pre, look elsewhere.
If you need visual feedback instead of developing listening skills, look “move on.”

However, if you need an inexpensive stereo line mixer for any one (or more) of those uses listed above...

If you prefer simplicity over complex tweak-ability...
If you want a device so rugged and simple it’s practically impossible to fail...
If you want to develop your listening skills. mixing skill or are just on a LOW BUDGET...

Art Mix pluses and minuses

Overall a great tool to use with various sources, in my case a turntable, iPhone, and laptop. There's minute channel bleedover that can't be completely eliminated, but doable. The one main problem is the adjustment for my external speakers and headphones cannot be separate for different volumes. I may want a "live" feel externally in my room to sound like I'm playing with a band, e.g. a drumless track song, but still use my headphones as a listening and protective device against high volumes. It's a very narrow balance that could have been better achieved with a separate voice control dividing the two external listening sources. Otherwise it does as advertised. For the price, a good start on the cheap to begin experimenting with loops and trackless songs instead of a metronomes' boring click.

Probably a good value

This is probably a good little mixer for the price. However, I will be returning mine because it has unbalanced main outs. That means I have to buy a stereo direct box for about $100. So, the effective price becomes about $200. At $200 you have lots of choices for small mixers.

One of the knobs has a flaw where they did not glue the white band correctly. It sticks up and there is dried glue all over the knob. That makes me wonder what else ART ignored during production.

Intended application: Keyboard submixer for live shows.

Move on

In trying to downsize my live performance rig I purchased this unit.

A/B tested against Soundcraft Notepad and Mackie 4 channel (vlz). I accept the lack of VU metering and that was okay, but the sonic quality of this unit was possibly the worst mixer I have owned. Not a case of "you get what you pay for" - the Mackie sounded like a Neve channel by comparison, the Soundcraft was like butter - better yet. I am trying to write a review that sticks for this unit, but it is hard to tell people to not buy this unit and have SW keep it on page.

Also...

-no notch for unity, so you are guessing
-knobs are way to close to be functional on stage
-What is unity on the unit - no really?
-could not get good sound with any combination of devices and levels

This is the second 'audiophile' product I have purchased form ART and I can safely say that they are no longer allowed in my studio.
