Deity BP-TX 2 Announced

But Resolve can't do (subframe) offsets AFAIK, nor scan for longer time (if TC does not start at the beginning, some action cams have a fade in....).
The devil is in the details. If all is perfect, it's fine, otherwise post gets expensive.
(And Resolve is a sledgehammer if you just want to deliver files with 'correct' TC.)

Allen doesnt seem too excited after real life testing.

 

 

After watching this I don't know how anyone could seriously consider this system. It's cool that it does all these things but if you're walking on eggshells with it all day worried about dropouts, what's the point.

On the other hand, if you’re a professional sound mixer looking for a wireless system, you probably wouldn’t consider a 2,4ghz system just simply because it’s 2,4ghz.

 

 The marketing is just unclear. he makes a point that it states it is a professional system, and it is, if you count amount of features only and build quality, and also if you compare it to other products in the same segment, it’s MORE professional in that regard. But no professional mixer would buy into a 2,4ghz system hoping they would replace their current systems. 
Maybe someone would consider buying it for ONE of the features, like TC. 
That section of the video was confusing. I didn’t understand if the stamped TC on the files actually matched the audio recorder’s tc. To me it seemed like he was comparing the displays in the different devices only. But I sort of half watched it at that point, so I could’ve easily missed something.

+1. The point about using photos to compare TC displays is kind of valid and overall it's a thorough review (i FF the walk tests:) but  a more real world use would be to Jam both devices to the same reference (eg the recorder), use the displays to confirm source and stick the BP-TRX on the cameras (and if you're working with a single camera with an audio I/P use the spare box to send a scratch track). I would not be surprised if there were drift in the compared files but he didn't seem to test this. There are also few TC devices which dont have a numeric display at all unless you are using an app.

I would have considered it for backup recorder, hops and scratch track on small jobs, but dont think I will replace my Tentacles and G3 for that purpose anytime soon.

 

Maybe as a TC stamped backup recorder, the EIN figure doesnt seem too great, but better than nothing.

What happens if Therese units get  very popular? So you arrive at some location and two other broadcast teams are using some trx? Will I still be able to use mine? You said there is maximum of four in total.

And because they have such a big output, they could easily interfere.

Ok, that’s exactly what I thought would happen!

Still I don’t get why it’s possible to send the signal of a single transmitter to three receivers but it’s not possible to pair say four transmitters to a stereo receiver and switch channels just for monitoring. This way you could save a lot of bandwidth in the crowded WiFi area because you could stop the transmitters that are not being monitored at the moment so that they are only recording internally..

And again this could be a solution. I guess they are made to record internally and use the receiver just for monitoring. This works as long as there is no problem with the sd card. If so the record symbols shows up on the duo rx when you start recording but than vanishes after a short time, even when there is no sd card inside which makes you believe you are recording.

Or if they just made the main buttons on the duo rx make you put recorders to sleep that you don’t want to monitor currently instead of stopping recording you could stop them from interfering.

Is there any reason that the deity trx cannot be built to work in the UHF-frequency-range?

 

Well, no, but UHF is a whole different ball game. The reason 2.4G is so popular with the lower cost systems is that the manufacturers buy chipsets that do all the wifi stuff for them. All the complexities (and it is really complex) of wifi transmission is figured out by vendors that specialize in making chips for the wifi standard. So you buy a chip, connect an antenna to it, send data to it and the chip works out all the complexities. Wifi is a standard that is run by billions of devices. Easy peasy to make a product for wifi, Well, relatively so compared to UHF.

 

UHF wireless audio works in the same spectrum as television channels and in the US, also in a space reserved for wireless microphones. So the UHF wireless has to abide by the FCC rules for this space, which don't allow for the things that wifi does and visa versa. They run under completely different rules.

 

Designing for UHF gets a bit more complex in that the designer has to do most of the work themselves. There isn't a 'billions of devices' market and so chipsets that do the RF stuff don't exist.  So there is quite a difference in developing products for UHF vs wifi.

I'm not well read up on the IEEE 802 standard (wifi), but from what I read I'm guessing this is a limitation of the wifi standard.

I messaged Allen on the Youtube video.  He says he will have more videos about timecode on the BP-TRX.

 

He also said there will be new firmware that fixes the display.

Did anyone test using two duo receivers connected via cable and receiving audio from four bp-trx transmitters, yet??

I am starting to think that this won't work at all..

The Deity Connect ecosystem isn't WiFi. It uses a different protocol on the 2.4Ghz spectrum. We selected 2.4Ghz because its usable world wide and you don't have to worry about frequency blocks when you travel abroad.

Yes this setup works. And you can trigger the individual recorders on each BP-TRX via the dual DUO-RX's UP and DOWN keys.

  The BP-TRX does not do wireless TC but rather each units features it's own TXCO to handle local TC generation. This gives for a more accurate clock.

Thanks for clarifying :) this thing has so many features I guess I got a bit carried away

thanks. I hope you can put units to sleep using up and down keys instead. There is plenty of memory space on the sd cards to keep recording running but not enough battery to keep transmission running all day. And I hope anyone will test the double duo receiver configuration. I ordered a second deluxe kit and hope I am not the first to test it.

I meant turning them to sleep with Up annd Down Keys INSTEAD of triggering record...

 

Do you know when the deluxe kit will be available again? I have still not received anything yet. Or are you working on a new, improved version?
