Now Indies can record and broadcast audio on the same device

Wireless audio streaming is a wonderful tool on set, but this new upgrade gives independent filmmakers access to a previously expensive feature: local backup and broadcast.

Most filmmakers first become familiar with radio technology on the set. Long before we broadcast video on set, the benefits of wireless audio streaming from a lavalier to a recorder-mounted receiver allowed for greater flexibility on the set.

However, if you’ve worked in a busy RF environment or large set, you quickly saw the limits of wireless audio. Other RF signals can cause interference, and if the performers move too far you can lose your audio signal entirely.

There are solutions to this for bigger budget productions, but due to a new licensing agreement, you now have access to a great solution with the new Deity BP-TRX that we covered a few months ago.

Units in the system can now simultaneously transmit audio and simultaneously record a copy locally.

For users, this means that you can monitor all audio recorded on your mixer. However, if there is any dropout or interference, you will have a local copy of that audio recorded at the source that you can use as a backup to go.

This is a huge upgrade for independent productions that record audio. The biggest application that comes to mind is a situation like a trade show or other live event with a lot of audio glitches.

Every time NFS NAB records, one of the most common tasks is finding a clean audio signal for the wireless microphone. With this setup, which also allows you to sync the timecode, you can literally only record the audio locally on the transmitter as well as the receiver mounted on the camera, and everything is synced almost automatically in post-production.

Another useful scenario is car work. As you drive around, you will regularly encounter glitches that you may not have at base camp. This means that many sound engineers are set up in the trunk or back seat with hard-wired lavaliers in order to avoid dropouts.

Deity is able to do all of this through a licensing agreement with Zaxcom, which first granted Zaxcom for its patent on the technology.

Zaxcom launched its TRX900 back in 2005 and received a patent for recording and transmitting timecode audio. For this reason, no other manufacturer has been able to offer this functionality so far. With this license, Deity is the first and definitely the first at an independent price to offer this option.

It is available to all BP-TRX users in North America starting with firmware 1.1, which was released in June.
