MixPre → 833 Bag Build: Installing the 833 and Wiring it Up
Dec 15, 2025
Let’s build a bag for the Sound Devices 833. More Videos: https://www.youtube.com/playlist?list=PLRetTs0Osqn0GMRwSsp0iSUlkZTbtH0LC
In this video, I’m building out my new Sound Devices 833 audio bag, replacing the MixPre-10 that I’ve been using full-time for the last three years.
I walk through how I physically bag the 833 in an OR-30 bag, how I wire power, inputs, outputs, and AES, and how I configure the system so it’s ready for real-world broadcast and location sound work.
This isn’t a “pretty” build — this is how I actually work on jobs for ESPN, Fox Sports, corporate, and documentary projects. Every jumper, cable choice, and routing decision is about speed, redundancy, and reliability in the field.
In this video you’ll see:
* Moving from a MixPre-10 to the Sound Devices 833
* Bag layout and fit inside an OR-30
* Power distribution and L-series backup batteries
* Installing the Sound Devices XL-AES adapter
* Wiring AES from a Wisycom MCR54
* Jumper philosophy for fast field work
* SD card setup, formatting, and test recording
* Timecode setup and jam with Tentacle
