Deity Launches a Little "Do Everything" Box with the BP-TRX

It does timecode, it records locally, it transmits audio signals—it even makes a smoothie.

The new little BP-TRX from Deity solves a lot of on-set audio problems in one little package. Announced last year, it's finally available for pre-order. We took a look at the handy audio tool!

Audio on set used to be pretty simple. You used a clap-slate to keep it in sync and recorded to 1/4" tape from a single boom pole. But as our technology has gotten more sophisticated, our needs have grown as well. While we still use a clapper slate as a backup, tight post timelines mean that timecode sync is preferred.

We want wireless receivers and transmitters delivering audio from the mixer to cameras, or from microphones back to the mixer. And we're so nervous about wireless signals getting interrupted, we want a local recording of the sound files as well as a safety backup.

With the tiny, 430g BP-TRX from Deity, you can now do all of those things in one box. It works both as a receiver and a transmitter. You can hook it up to a lavalier and put it in someone's pocket as a wireless transmitter. You can put it on your mixer as a receiver. Or you can put it on the camera to receive something transmitted from the mixer. You can even hook it to a set of headphones as a director's monitor.

On top of that, it offers internal recording, so you can record files internally if you are in a busy RF interference zone and worried about drop-outs and static in your audio. But best of all, it works with timecode in its local recording, but it can also receive and create timecode for sync.

Imagine the scenario of a multi-camera shoot where you want to be able to bring all your cameras together into post and have them just sync together automatically without any extra work (remember, we never have much time in post these days).

With these devices, you jam-sync the timecode together, then mount one to each camera, and they'll deliver timecode to each one, keeping them in sync. This is traditionally something you need to buy an extra device to do, but with the TRX it all comes as part of the package.

Add in a fourth BP-TRX on the lead actor for their lavalier, and it should all come together perfectly in sync in post.

It does all this from an internal battery that gives you 130 minutes of working time, which is plenty for an interview or a stand-up. If you need more time, it takes power via USB-C, which is increasingly common for smaller film accessories, so you can run a USB cable from your battery or power distribution to keep it going all day without thinking about it.

Available now as individual units or in kits that combine two BP-TRX for timecode or two units and a receiver for independent productions.

For those in the states like me, this sounds awesome until you read the disclaimers at the bottom (pasted below.) Maybe it's a patent issue? Privacy? Either way, it's a bummer.

*BP-TRX units sold/shipped to the USA do not currently transmit and record simultaneously

***Remote control triggering of a BP-TRX’s internal recorder is disabled on units sold/shipped to the USA

It's a patent issue. If I recall, Zaxcom are the ones who hold the patent.

Rode has figured a way around this with their Wireless go II set. Never been a fan of Aputure's attempt at audio... solid lights though.

I was excited about it until I got to the bit about 130 minutes of battery life. But then I checked the Deity webpage linked in the article and it says 12+ hours. So now I'm excited again. Where did you get the 130 minutes stat from?

exactly what I thought, excited until I saw 130 minutes, If so that's one of the lowest battery life in all wireless lavs haha
