Good video as usual. If I may point out a few things. As you pointed out analog FM wireless systems do not transmit constant RF but a modulated RF band, the RF transmitter frequency is modulated by the audio information. So each transmitter must use an RF band width as mentioned, of about 200 MHz in order to transmit audio content within 20 Hz to 20KHz including amplitude information. So if two wireless transmitters were used simultaneously they would need to use two different frequency bands. A rare issue that could occur is interference between two wireless systems if their respective bands are set too close to each other. Because an analog transmitter requires a 200 MHz RF band to function, the available RF space becomes limited and restricts the number of analog RF systems that can be used together at the same time. Regarding digital wireless, the transmitter only needs to transmit an RF modulated signal consisting of ones and zeros. This reduces the bandwidth requirement considerably and allows more transmitters to work within the same band. And as John McGregor mentioned there are still steps to be taken to minimize interference. I hope you will cover digital wireless and the pros and cons of using entry level systems as opposed to more professional systems in more detail at a later date.
200 kHz-wide channels, not MHz :-) WMAS is an interesting TDM-based approach to using 2/6/8 MHz channels in the duplex gap, but it's not universal yet. Up to 64 audio channels (in or out) from a 1RU unit looks pretty interesting though.
Great video, great conversation, cool of mr. McGregor to participate.
Glad you enjoyed it!
Just in correct time...Well apprecited
Glad to help!
I love this stuff, thanks! And you explain things in terms we all can understand.
Glad to hear it! Thank you!
Extremely concise and useful info. Great video! 📻
Thanks for your efforts
It's my pleasure. Thank for watching!
Cheers.
Cheers!
My band leader is a bit slow to tech. Well after many years of owning a wireless in-ear system he finally got a digital board to go with it and build out an in-ear rig. So he got everyone together to get it all setup and try it out and.... it's a 600mhz system. It wouldn't work at all because the background noise from digital TV totally drowned it out.
Id love some info on lavalier mics, and how they can sound good while being so small.
What specs would you even look for in a good laminar mic?
Do you mean Lavalier? Laminar is not something I've heard used surrounding microphones before.
@@matthewmason7753 yah yah yah my bad LOL.
My hands moved without my brain... typing too quickly.
i wonder if they will come out with a LAV mic that is 32 bit float that way you cant clip it at the lav
@Dogo.R Have you seen this video? ruclips.net/video/0Ir4yztgjG0/видео.htmlsi=yQwQsOwyYQiiJRg5
@YoungBlaze Some recording devices record in 32-bit float. Sometimes the device is inside the mic, sometimes it’s external. So, any lavalier microphone could work with a 32-bit float recorder.
Excellent video
I was in a club the other day, and they turned the mic off before muting, and it instantly sent pink noise through the system, happy to see its normal i guess :D
Excellent video and very informative. Sounds a bit ominous though that the big players have so much money to direct usable frequencies which only drives the prices up for consumers. I have quite a bit of wireless gear that some may classify as cheap (I say less expensive) and it sounds as if it could all be obsolete in the near future.

Good information 👌🤝💐
Is it possible to use wireless mic with different frequency band and same channel no simultaneously
The background noise elimination filter sound in this video is killing me...
Which receiver you used
How to decide the no of group and channels required for a multi channel wireless system
Its clearly an audio yt channel.. Because half of the shots have a boom mic above you Kyle XDDD
Mic stand malfunction!
the power ADAPTOR easily get spoiled and the service of Sennheiser in Singapore is very Bad!!!!
You could make informative content just as well without big brands sitting in and making it about their specific products
