Good luck. Hopefully no planes or other motorized vehicles around. What microphones are you going to use and what kind of wind protection?

You're lucky. Everything above 614 will work for you and it is allowed for professional users. 614-622 (EU TV Channel 39) is best.

Not to forget EK 3241

Ready-to-use mono mix to all cameras via camera hop, sometimes (mostly when it's about music) a stereo mix. So the footage can immediately be used for viewing, broadcast and internet, primiraly social media. Additionally providing a TC synced multitrack file.

+ 1 for Ambient. I've been using that system for years and really rely on it. You should have to know about TC and sync is about to set it right. There are many options in the menu that may lead to fail. After FW updates you have to reactivate the genlock function for instance. Over here in Germany there's the advantage that you can expand your setup easily with rental units or even buy older units from the used market. All devices will function together without an issue, even old CL204 and older slates will receive continuous jam from brand new Lockit CL and vice versa. Ambient's service is also quite good (at least if you are based here).

Someone from Denmark made an analogue-in cable, haven't tested it yet: https://nordicproaudio.com/wireless-audio/wireless-accessories/reciever-accessories/npa-fxhac-hotshoe-adaptercable-for-fx6-analogue-audio-on-channel-3-4

Bought it from manufacturer

I had it on for a show where random people in the streets were questioned about recent political things by a presenter. It was a kind of "run and gun" shoot. The presenter was of course laved and the people not because everything had to be spontaneous. Shot by two FX9 for each wide and narrow shot and presenter shot. The Boom Rig helped A LOT in this scenario to keep the right distance above the heads for an unpredictable period of time - you didn't know how the discussion would develop. The mixer was fixed on the Boom Rig front holder which I found pretty comfortable. But, after some hours, you realize that it is as heavy as always. I guess wouldn't use it where maximum flexibility is needed and takes are shorter but on that day it saved my life.

All supercardioid capsules I ever had in my hands, no matter which brand or purpose or price, were at least 6dB quieter than the cardiods. The omnis always are the loudest. It's physics I guess

Use the LTC "USB style" input of the FX3. If you have done so, everything correct and for me it seems like they didn't extract the TC properly from the HDMI stream provided by the FX3. Possibly a wrong setting in the Atomos or camera or both. There may also be an accuracy in this setup, but constant and only 2 or 3 frames, caused by the camera.

Probably just get something like this. So you can power your receivers as well: https://www.shop-ftt.de/de/kortwich-produkte/np-f

They've been putting all energy and human resources on developing their wireless stuff for quite a while. So new mixer product in the next months or even years, neither 8 series nor MixPre.

RF Venue 4 Zone is probably the product you've been looking for. Unfortunately AC powered and bulky: 19 inch wide.

They can be hidden in plain sight during the next corporate shoot for Disney World.
