Have you looked at the Denecke Dcode gadgets?

As I suspected, the edit function is completely gone.

WHAT HAPPENED TO THE EDIT AN DELETE FUNCTIONS AROUND HERE?
Since I can’t edit or delete the previous posting, please replace it with this…I don’t hear any distortion, clipping, or even microphone rubbing, etc. Anything that could be described as “scratchy”. I am wondering if we are hearing the right clip?
The two major problems with this sound recording are:
1) Poor signal-to-noise ratio. By noise, I specifically mean HUM. I cannot tell from listening whether this is electromagnetically induced into your gear somehow from a nearby magnetic field (like a lamp ballast, etc.) Or whether the hum is ACOUSTIC being picked up through the air (like from an exhaust fan or something?) The easy way to differentiate whether it is induced or acoustic is to simply do some critical listening with your ears. Do you hear that same hum with your ears in the open air? Or can you hear the hum only through your monitor headphones.
2) Less than optimal speech pickup from microphone position too far away or “shaded” or aimed in the wrong direction, etc. etc. There could be several causes for this and only experimenting with the mic placement and listening through your good monitor headphones will identify the issue.
The default microphone heads that come even with expensive wireless kits are not known for their high performance. And the default microphone that comes with a $150 wireless microphone kit can’t be expected to offer even “average” quality. You get what you pay for. How do similar shots with your wired microphones sound by comparison? If you like your wired mics, can you use them with the wireless transmitter?
Twice now I have mentioned having GOOD monitor headphones while recording. A good pair of over-the-ear headphones is MANDATORY whenever you are recording audio. Please see my signature line if there is any confusion here.

Did you post the correct clip? I don’t hear anything I would call “scratchy”.
What I DO hear is rather high ambient noise.
That is quite independent of whether you are using a wired or a wireless mic, and what kind of wireless mic. -
There are several different sources of noise that could be called “static noise”. It is impossible to even identify what kind of noise without listening to a sample audio clip.
Note that you purchased the very bottom of the barrel equipment. A halfway-decent wireless mic kit starts at prices 3x to 4x what you paid. and professional models easily go up to 20x what you paid. And Azden has rather a poor reputation as a cheap low-cost, low-performance brand.

1. The Behringer Ultra Curve Pro DEQ2496 is typically used to convert analog audio into AES/EBU digital to feed into the ATEM TVS video switcher. And the DEQ2496 can be set to compensate for the video delay in the ATEM switcher.
The digital output from the DEQ2496 is a balanced XLR connection, but the digital audio input to the ATEM TVS is an unbalanced BNC connector. I made my own adapter cable for this connection, but you can buy them for reasonable prices if you don’t want to DIY.
2. You might be better off NOT “daisy-chaining” your video through the HyperDeck Shuttle recorder. It would be safer to take two ouptuts from the TVS, and run one of them to the recorder, and another to your computer capture card. That way, your computer signal/recording/live stream is not dependent on the HyperDeck. There are several program outputs from the TVS, so you should not have to daisy-chain the program video signal.
3. You must select the video input card and streaming software that will operate on YOUR computer. There is no future in buying hardware or software that is not capable of operating with your computer.
4. There are many video distribution amplifier products. The Kanex is only one option. NOTE however, that sending video signals more than 2-3m over HDMI is very frequently problematic. It is MUCH MUCH MORE RELIABLE to distribute HD digital video via HD-SDI coaxial cable. We typically use “antenna-grade” RG6 from the home improvement store as it is quite inexpensive but works very reliably up to 100m or 300 ft. Highly recommend distributing HD video over SDI and then converting to HDMI at the destination end (the various monitor screens or projectors, etc.) SDI to HDMI converters are quite inexpensive these days.

There is no FUNDAMENTAL reason that a switch-mode power-supply (SMPS) wouldn’t be suitable for most ANY application. Like everything else there are good SMPS and bad ones. And loads (like your mixer) that are happy with a variety of sources, and those which are very picky. This cannot be answered as a generic question.

To expand on Mr. Watson’s information about selecting a quiet location, suggest reviewing this valuable information:

Yes, I agree that if the wireless signal is reliable enough (considering that you are competing with WiFi and all the other BlueTooth gadgets in the room), then it would be a potential solution to establish the offset factor by careful experiment.
The only remaining issue would be to get a properly-wired attenuating cable to take the line-level output from the SoundDevices 744 and knock it down to mic-level for the Sony Bluetooth transmitter. It isn’t rocket surgery, but it isn’t trivial, either.

No, No, and Yes.
No, a digital system like Azden PRO-XD (or any of the 2.4GHz wireless mic kits) are strictly paired one transmitter to one receiver. There is no provision in the protocol for the receiver to handle more than one transmitter per customer.
No. Even a conventional analog wireless kit will receive only one transmitter per receiver. If you attempt to use two transmitters on the same channel you will get a myriad of interference patterns that will render BOTH mic signals unusable.
Yes. There are SOME wireless kits (like Azden 300 series) which have TWO receivers built into the same box. They can handle two transmitters independently.
