You can use this to mix the 3 W/D/W outs from the SDE into your stereo pwr amp L wet/C dry/R wet , just very cool and no need for the 3 amp thing. Contrary to the other review, unbalanced is exactly what is needed. It's a low tech solution for a complex hookup.

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.

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...

This little guy ROCKS !

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.

I just got this and set it up, but then noticed a deal breaker for me: Even if an input is turned all the way down, you can still hear it quite well. Zero on a mixer needs to be absolute zero, you can't have leakage like this.

Other than that, the build quality etc seems great, but like I said, it fails at its core job of being a good mixer.
