    Azden FMX-42u reviews

    FMX-42u 4-Channel Microphone Field Mixer with USB Digital Audio Output is rated 4.7 out of 5 by 3.
    Rated 5 out of 5 by from 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.

    Rated 5 out of 5 by from 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.

    Rated 4 out of 5 by from 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.
