BEST BANG FOR THE BUCK

Do not use any type of batteries other than AA Alkalines or things can distort. This is a top quality mixer, you can't go wrong.

Very nice, low cost mixer.

Very nice, low cost mixer. I replaced a Shure FP32 with this new Azden and I'm very happy. The only weird thing is having to take it apart to flip the dip switch to set the VU meters to work with line output vs. mic output.

great value

I labored over the purchase of this mixer. As a freelance videographer, I need a decent quality mixer but I have to spend my pennies wisely. I came within a hair of getting the tried and true Sound Devices 302 but I took a big chance and decided to get the Azden at 1/3 the price. The build of this mixer is excellent and the sound quality has been great for my needs. I do a lot of corporate and industrial video as well as some indie work where margins are really tight, but the FMX-42u has delivered the sound I need for my purposes. If you need a solid mixer that will get the job done and don't require top tier gear to impress your producer, give this mixer a try.

Solid performer

I bought this when I was starting out and have found it to be a great tool. Pretty simple to use and understand. The USB option is great for feeding right into my laptop. The noise factor is minimal and I've never had a production problem that stemmed from this recorder. It has only solved problems. Great mixer for the money.

Good Sound Quality

This seems to be a great little machine for sound quality. However, the knobs on the controls seem pretty flimsy. I also wish that they had included the USB cable with the system. That was the selling factor on this device over others and it would have been great to have that immediately available.

Can this be mounted between a camera and a tripod/monopod? Or; must it be carried in a shoulder bag?
Asked by: John
This mixer is designed to be carried in a shoulder bag. There are no threads for mounting. If you want a mixer that can be mounted between a camera and tripod, check out the FMX-DSLR.

do you get all four of the outputs from the usb?

do you get all four of the outputs from the usb?
Asked by: Mark
According to page 05 in the manual, you would get a single stereo (left and right) channel output via USB into your computer. https://www.azden.com/wp-content/uploads/pdf/FMX-42a_42u.pdf
