Now we are talking. The Yamaha mixer improved the mic pickup tremendously. The "on" button is a must when you have multiple mics running but need a quick way to suppress someone. The layout is clean and easy.

    "On" button, sensitivity, layout.

    Volume sliders could use a little better quality build.

The Yamaha mixers are the perfect solution to your audio mixing needs. Quality built and reasonable priced. Take yours home today and perform your music like there's no tomorrow.

Sound quality is good but the usb input seems to bypass effects. Documentation is minimal and there are numerous pads, switches, knobs and control settings which are somewhat less intuitive than I would prefer. It'll be a learning curve,

Only reason i didn't give 5 stars is the switch pot on the effects knob is a little iffy. I had to pull it off and sand it shorter to make the attenuation work reliably. Other than that it's great.

I use this mixer for church audio and video mixing. The sound quality is excellent. It is very easy to use and control panel is laid out very nice. The USB port is a very nice feature as well.

Lightweight, easy to use and great sound. I just wanted a portable mixer with enough channels to do the gig - and this one fills the bill. I would've given it a 5 star rating if ALL channels had had mid range EQ. Other than that, I'm very happy. No more racks for me!

I just installed two of these mixers in some small classrooms and they sound great. I love the USB audio feature and the overall feature set of these notepad mixers. I really like the compressor as it is something you wouldn't typically see on a mixer this size.

Just started using this mixer with 2 QSC K10s in our jazz quartet and although I haven't used it all that much yet, I do love the sound that we're getting. I go stereo in with my two keybards, the bass goes direct, and the sax/flute is mic'ed and also run through this board.
