    Azden FMX-42a reviews

    FMX-42a 4-Channel Microphone Field Mixer with 10-Pin Camera Return is rated 4.5 out of 5 by 20.
    Rated 3 out of 5 by from A bit short of a home run This little mixer has a great set of features and is a lot of mixer for the money. The individual control over phantom power on each channel, as well as the individual gain adjustments on each input are extremely useful. When the breakaway cable becomes available it will be a major plus, although at an estimated release price of $200.00 it's surprisngly expensive. My only 2 disappointments are that the the gain on each channel is a bit weak compared to my much older Shure M-367 and the meters are not very responsive, in fact almost useless.I also think the ac adapter should have been included. Overall, it's a good product that needs a couple of tweaks to make it a great product.

    Rated 5 out of 5 by from Solid Choice I used this mixer for the better part of a season on an ocean focused natural history show. Complete run and gun. Its packed with features. No rust from salt water spray (yet). It's been banged up from a lot of travel (always in a checked in pelican) and didn't miss a beat. Just recently (season 2) another sound guy on the show somehow broke the headphone monitoring jack by jamming in the monitoring volume knob, so it isnt invincible, but it can take a beating. For the price, nothing I know of comes close. It's like the 5D MKII of the sound world. Comes with a little bag, which is handy but you'll either want to get a pro bag for it (Porta Brace makes one), or Velcro an extra pouch onto it to make it usable.

    Rated 4 out of 5 by from Solid Field Mixer Great for when I don't have an audio guy, or for my PA to run audio. The Meters are a bit finicky, but you can calibrate them and they are more than passable. Best if you can also see the camera's meters while operating for a little extra confidence if you want to ride the levels on the higher side. Excellent low-noise performance and many great features, including multiple mic levels, return monitoring, low end filter, and panning (which is particularly nice if you only have one mic, and want to run one channel at a different level to save any sudden spikes in level, like when a speaker suddenly becomes passionately loud..)

    Rated 5 out of 5 by from Great replacement for Shure FP32 I am a broadcast ENG audio mixer and just used my new FMX-42a on a 5 day shoot. I have used a Shure FP-32 for 10 years and it finally needed to be replaced. Overall, great sound, intuitive controls, solid build and feel for the Azden. Also, great to have the 4th channel if needed. The camera return feature on the 42a worked well and was worth the extra expense over the FMX-42. Only things I missed from the Shure was a battery charge check feature and a front panel headphone level control. The level control on the FMX-42 is on the side of the mixer - good so you don't accidentally hit it, but hard to reach through my audio vest. Battery performance was excellent. VU meters were responsive and accurate. Great mixer especially for the price and a great replacement for the Shure FP32.

    Rated 4 out of 5 by from Great Mixer I use this mixer on a web show I produce. The audio quality is great for the price. I does exhibit a very small amount of hiss, but only when both the channel and master gain are maxed out, and only with certain mics. The return audio is great, as I can use it for mixing more than two channels with my H4n. Lasted 7 hr with Ni-Mh's phantom power and meter lights on. Azden makes great stuff, don't underestimate them.

    Rated 4 out of 5 by from Very Good For The Price I work with sound for video (commercials, industrials, etc.) and it is hard to beat this unit for the price. I've only used it for one job so far but I have done quite a bit of testing. Pros: Multiple dBu input settings (+4 Line, -30 Mic, -55 Mic). So far, very good sound quality. Batteries last quite a while. 4 XLR inputs, each with separate 48v phantom switching. 10 pin Hirose connector for break away cable is a must for me. Being able to switch monitoring between output and return signals is great. Not mentioned in the literature or anywhere else that I can find... you can output to at least 2 recorders! If you use the 10-pin with a breakaway cable, then the standard output XLR's are free also and when I tested them at the same time, I got no downgrade in signal. This means output to a camera and a recorder, or 2 cameras, or 2 recorders. Also, there is a 1/8 stereo output jack (-36 dBu) that I haven't tested yet, making a possible 3rd output! Although small, it feels and looks sturdy. Comes with a carrying bag. Nothing to write home about, but at least there is one. Cons: Does not come with an A/C to D/C power supply! What the Heck? You have to order it separately. This is the main reason I dinged this review down to 4 stars. Also, if you order one from Azden, make sure you order it with the correct connector... it takes a 4-pin Hirose and not a standard coax that they will send you if you order the PS that is stated on their web site. I had to send mine back for them to exchange it. Order the BC-27H (H is for Hirose), not the BC-27. The power / low battery indicator led is very tiny and easily not noticed. They should have it blink when battery power is low and not just change color. The inputs are only XLR. It would make the unit more versatile to have these as combination XLR / 1/4 TRS connectors. The instruction manual is very sparse and lacks a lot of info that I had to learn by going online or testing. It would be nice for Azden to add to the output switch -10 dBu for consumer line signal in addition to the +4 professional line signal and the -36 mic line output already supplied. Some digital recorders out there use -10 for their line input.

    Rated 4 out of 5 by from just used for first job good for the price. needs a little more gain on channel knobs. needs more output gain control other than the two positions it gives. also, switch batteries often! when they run the slightest bit low you loose a lot of power in the unit. everything then must be cranked up and the the risk of blown out sound happens, especially when rolling with lavalieres. overall, it is not a sound devices 442, but for the money very acceptable.

    Rated 4 out of 5 by from A little Gem! As an old field soundo sneaking back into the game, I was on the lookout for a field mixer that reminded me of the old Sony MXP42 I used to run. Without the first up cost! Found it. I think a lot of people would say the standard thing of, too cheap, Rubbish, and such, but for the price? It has all the specs! 4 into 2 with lots of output options, light! Tough is yet to be found out, but with consideration, it should last. Pre fade levels would have been nice, but, for the quid, I don't think there is much out there that is any better.
