    Lectrosonics vs Audio Limited

    Second generation. the first one was the a1010. introduced 3 years ago at IBC 2015.

    Yes; because it has the adaptive frequency hopping. It sees that the analoque/wifi/teradeck/whatever device is occupying a frequency/channel and hops around it. Doesn't matter what flavour or protocol.

    First, there is de adaptive frequency hopping technology, to stay out of the way of any flavour of WiFi in the 2.4 ghz range in the first place. second, (all?) flavours of WiFi have the LBT (listen before talk) standard implemented, and not a continuously uninterruptible (back to back) data stream by the way. So in case of any "traffic jam" a Deity with a Wifi channel, it can finish the time slot, before moving over (remember; adaptive frequency hopping, is per time slot) to a different empty space in the spectrum. Also Wifi hardly ever is using the full spectrum of a channel (22mhz) due to overlap, thus leaving more gaps to "hop in.

    They will and they have too by law, both for Europe and USA, otherwise they can not sell it, simply. Also, the chip inside the device is already tested and allowed by FCC (and in EU), with exactly the intended purpose of the Deity devices. I don't exactly understand what you try to prove/say here; the technology is not particularly new by any means. Also, disclosure, I worked for Deity at last IBC convention in Amsterdam.

    Could be should be would be, my guess is that FCC doesn't sign of a chip/protocol if indeed it is fucking up a whole spectrum.

    No, because the needed bandwidth is higher/wider for uncompressed audio streams. My example is just to illustrate the capabilities. Because the Deity system uses 8-FSK to modulate, it will degrease the need of bandwidth per channel (3.8 mhz @ 5mb/s vs 22mhz per channel for "regular" wifi). In practice this means that theoretically one can use 18 systems together (36 channels of audio) but recommendation is to keep it to 3/4 systems (6/8 audio channels) for reliability, because we probably will use it in a bag thus the receivers will be close together. correction: it is actually 4 mhz per channel, for some overhead and back and forth data transmission, like accessing the menu settings from the receiver.

    You are not messing with the 2.4 spectrum. Adaptive freq hopping (frequency-hopping spread spectrum) is FCC an approved method, and the EU regulators are accepting it as well with a bit more clarification from the manufacturer. Check out this Guinness World Record, they used the same technology to fly 179 RC airplanes at the same time: http://www.guinnessworldrecords.com/news/2017/8/video-watch-179-rc-model-aircraft-flying-at-the-same-time-485624
  9. I wouldn't bother with that; just use a TC device/Tentacle for the TC on the hybrid TC/Audio input and use the build in mic from the camera for scratch. If you want you can use a camera hop track on the xlr input. My guess is the build in mics of the BMPCC are better than the tiny scratch mic of the tentacle sync. The reason they buid it was for DSLR cameras, because when you want to use the mic in it bypasses the internal mic. I believe the BMPCC just lets you select whatever you want via the menu.

    Yes, you can use them with a BDS system in a bag.

    Don't forget that this is also a revision of a product, so although I can not backup my claim with any evidence, it is most likely that they upgraded some parts of the design under the hood we don't directly notice as an improvement. Think thinks like better shielding, stronger connectors for screens (the first generation had a problem in the beginning causing screens to go white).

    Comparison of different transmitters

    thanks for the upload @Constantin. I don't have a good listening setup at my current location, but will check them when I have.

    Audio Limited A10 for talent.

    If you can post some files on Wetransfer or something that would be nice, also potentially for SD/Audio ltd/Zaxcom to comment on your specific tests.

    Not true, the Deity system will 'multicast' and an IFB system is on the roadmap for next year, as well as other transmitter/receiver units.

    you know what? that is most likely your phone's antenna, or lack of a proper antenna. Now, to get full circle to the Deity mics, since they have proper SMA connectors we can use a whole bunch of readily available 2.4 ghz outdoor antennae with insane performance, without even the need to use a active antenna amp. Even smaller ones for in the bag (like 30 cm high) can boost significantly.

    The best example of Frequency-hopping spread spectrum (although the slow variant) is mobile phones. Hundreds of phones can be connected to one cell tower and use a relatively small band but still can connect and get service. That is, per cell tower. Indeed with different towers next to eachother you can even increase the numbers by a lot (think festivals where thousands of people gather, they put up Ad hoc cell towers). So they technology quite solid actually.

    You make some excellent points. The fact of the matter is that it is basically like how Mozgear does it already; The TX has 4 screws, you can undo them, the lipo cell is just attached with 2 leads to the board. instead of a proprietary battery from one of the camera brands, you can use any 1 cell lipo battery ( it is a standardised connector) or buy spare ones from Deity directly (they will be available for sale). they are chargeable with any RC /car/drone style charger, so pick a good one or use the one you might already have. So yeah, in case of an emergency (again, with a run time of 15 hours+ realistically...) it takes as long as it takes you to undo 4 screws in the field the swap out a TX battery and that is about it. But yeah, that is how you can have a redundant solution. About the YELLOW, yes that will be black, with a tiny bit branding yellow, nothing intrusive. I already saw the mockup of the new design.

    No: the numbers quoted are under the WORST circumstances. And from the conservative kind. Here at the booth the run from about 9:00 till over 18:00 every day without charging or some kind of lunch turn down, and the battery meter still give a couple of bars at the end of the day. We have set them to 100mw. Like I said, because of the auto RF function it will be highly unlikely you will have them continuously blasting 100mw for 10 hours a day. So a real world conservative 15 hours usage will not be unlikely to get. As for the shit hits the storm, we can't charge, we forgot it or whatever reason, I get that, that's personally I guess, and I see the obligations. Other way around; the charging is done with a quick charge chip; 1 hour to completely recharge it. So let's say you forgot it; 10 minutes of charging gives you a couple of hours of usage. If I would use these things in a bag situation, I can imagine having some leads in my bag, and everytime they got put back in the bag, the get some charging time from the battery/distro in the bag. I do this already with my tentacle syncs and phones I have to use for the various control apps for the various devices. Personally I think internal batteries are something we get scared of because we are not used to have a workflow around them because we are not used to it, but it's something to overcome. And if all the specs and promises got worked out of this system, it wouldn't be a deal-breaker I would say. It's a common comment, also here at IBC, the lack of battery swapping. The official word (by Andrew and the engineer of the devices) is that it is a compromise; making something swappable needs real estate. You have some sort of hinge/door/lock mechanism and that needs room. You get the room by making the device bigger, or the battery smaller (thus less capacity). But indeed all feedback is being noted and taken into consideration.

    The 10 hours is based on 100 mw RF power. Let's say you use 50 mw, it's should be close to 18 hours. Now there is a neat feature; it also has an auto RF mode. So it constantly is analysing the need for power; is it a couple feet away, it switches to 10mw for example, does the actor walks away, it goes to 25/50 etc. So let's say you are really concerned, you could potentially switch the TX to 10mw everytime there is a light change or long down time, so the run time could easily be around 20h or even more per charge if you follow a certain system for that. That said, the firmware isn't final and there is plenty room for improvement so maybe even more is possible (sleep mode, no transmission on mute thus really low usage, etc). The internal battery will be relatively easily serviceable, screw the case open, disconnect the lead of the battery and pop a new one in. Disclosure; I was invited to work on the Deity booth at the IBC, so I have first hand experience with these prototypes. When the show I over I will write a full 'preview' on all the capabilities and limitations from what I have experienced.

    new NDI coming!

    Indeed a cool technology, I'm following this already for a couple of years, the SDK is not that complicated so it shouldn't be too difficult to implement it in existing products. One correction though, it is not open source, it is royalty free.

    In ear monitors for production sound

    Aren't these meant to be used for IFB (not critical) monitoring, and only one ear?

    Deity Microphones going Wireless

    Some interesting Quotes on the new Wireless, why they choose 2.4 ghz and why current 2.4 offerings are not working properly: https://wavreport.com/2018/06/17/this-week-in-sound-8/
  24. They are asking us for input, what we wanna see in an upcoming new wireless RX/TX kit. It's a tough market with fairly reasonable options from Sony and Sennheiser in the low budget segment, so interesting to see what they will come with to compete with these industry giants. https://wavreport.com/2018/06/04/deity-microphones-going-wireless/

    Funny how much the deal is cheaper than if you buy just the F8 by itself
