Deity C21

What is the C21?

The Deity C21 is a non-locking 3.5mm TRS to USB-C digital audio adapting cable.

Why does it matter?

What this means is that you can use it to turn a passive video microphone into a USB mic. As long as it’s got a 3.5mm connection, the C21 can handle it!

More impressively, it can also convert a timecode generator to talk with DJI cameras. Allowing them to keep in sync with all the other devices on set.

What’s in the box?

The cable…what else?

OH, and a silica packet…don’t eat that…

Connecting the C21 to PC

The C21 is compatible with every major operating system such as Windows, Mac, Linux, and Chrome.

No proprietary drivers are needed, the cable utilizes the ones you already have!

Simple go to your computer’s sound setting and make sure “USB PnP Audio Device” is selected.

Any brand, anytime.

The C21 is compatible with brands beyond Deity, so keep using the devices you love.

Some of these include Comica, Sennheiser, Saramonic, and Rode, really, anything that’s got a 3.5mm connection.

The C21 is also capable of providing the 3V required for passive microphones.

Connecting the C21 to DJI cameras

Match the Deity TC-1 settings to your DJI camera, and simply plug it into the timecode menu.

Boom, your device will recognize this signal and embed the timecode.

Cameras tend to drift after a while so be sure to re-jam every so often throughout the day.
