Feature:
The built in effects are pretty terrible, you really need to crank the reverb to even know it's on. If you want effects, by a smaller/inexpensive mixer and a seperate effect unit. Each channel also has Compression. Again, if you really want true compression, go another route. So essentially I use outboard gear and just use this as a mixer, and it's fine for that. My only other complaint is that I have a slant rack road case and you cannot use this mixer in any type of rack case, no extension pieces or anything so I had to use a plank of wood and velcro the mixer to it. Channel 11/12 which has the RCA ins is a nice touch for playback from an outside audio source. Haven't used the ophantom power but I think it's there.

Quality:
Seems pretty well built. I haven't thrown it across the room in a rock and roll rage though yet or lugged it from club to club, so...

Value:
Hmmmm...again, purely used as a mixer to route signal, fine, no problems. But given the built-in effects are shoddy I'd say it's not the best bang for your buck out there, but I didn't feel ripped off either.

Desirability:
If it were a member of the opposite sex, I wouldn't need a 12 pack to sleep with it, but a little buzz wouldn't hurt.

Sound:
Sound quality is ok, as long as you are just using it as a mixer and not adding any built in effects or anything. Mid to high end frequencies can be processed a little tinnier than desired, but for the money I was spending, I knew what to expect. I am not dissapointed with what I got, but nor did it blow me away. It simply is what it is for the money.

Ease of Use:
Well, have you ever used a mixer before? If you have some knowledge you'll be fine. The manual will not help you learn to route signal though. It's intuitive enough.

Support:
Support...I think we can all use a little support in these uncertain times, don't you? haven't had to...

Overall:
Overall, it does the job. I just stress if you want more than a pure mixer (like effects and so on) look further. But it has enough XLR ins for most rock/pop band applications. I've had at least a handful of other mixers be it powered or not, effects or no, and this is not the best but not the worst. For my situation, i wanted to spend more on speakers and the actual power amp, knowing in time I would upgrade this piece. I'm satisfied with it but not running to mountain tops to shout Yamaha Mixers for everybody!

Overall:
It's an inexpensive little mixer that is suitable for a singer/songwriter or a small band. A lot of features for the price.
