The Blackmagic Design Spares - Camera URSA Mini - XLR Input Cable is an internal replacement loom that connects the two professional XLR audio inputs on the camera's chassis to the internal Audio or Main PCB.

Unlike an external microphone cable, this is a delicate, shielded internal component designed to carry balanced analog signals through the cramped, electronically "noisy" environment of the camera body without picking up interference from the high-speed processors or fans.

Anatomy of the Cable

This spare usually consists of:

  • Dual XLR Female Headers: High-quality, locking 3-pin connectors that mount flush to the URSA Mini's side or rear panel.

  • Shielded Twisted-Pair Wiring: Each channel is individually shielded to prevent "crosstalk" and electromagnetic interference (EMI).

  • Internal Multi-Pin Connector: A small Molex or fine-pitch header that snaps onto the internal audio circuitry of the camera.

When to Replace This Cable

While the XLR ports are rugged, they are subject to significant mechanical stress over time.

  • Physical Port Damage: If a heavy XLR cable is yanked or tripped over, it can bend the internal pins of the port or snap the solder joints where the wire meets the connector.

  • "Crackle" or Signal Drop: If you lose audio when the plugged-in XLR cable is wiggled, it usually indicates that the internal wire has frayed or the shielding has failed inside the camera.

  • Broken Locking Latches: If the silver "push" tab on the XLR port falls off or snaps, the internal assembly usually needs to be replaced to ensure microphones stay securely locked in.

  • Phantom Power Issues: If the camera fails to provide 48V power to a specific port, but the software settings are correct, there may be a short or a break in the internal power delivery wire within this loom.


Technical Installation Note

Replacing the internal XLR cable involves opening the URSA Mini's outer magnesium shell. It is a "Level 2" repair, requiring patience and the right tools.

  • Chassis Access: You will need to remove the side panel screws. Keep track of these, as they are often different lengths and must go back into their specific holes to avoid puncturing internal components.

  • Sealing and Gaskets: When removing the old XLR ports, be careful not to lose or tear the rubber weather-sealing gaskets. These prevent dust and moisture from entering the electronics through the audio ports.

  • Cable Routing: Pay close attention to how the original cable is routed. Blackmagic designs the internal layout strictly; if the new cable is routed incorrectly, it can be pinched by the cooling fans or crushed when you screw the side panel back on.

  • Strain Relief: Ensure the ports are screwed tightly to the chassis before connecting the cable to the internal board. The chassis should take the mechanical weight of external cables, not the internal PCB.

Compatible Models

This spare is generally standardized for the URSA Mini chassis, including:

  • URSA Mini 4K / 4.6K

  • URSA Mini Pro 4.6K (G1 / G2)

  • URSA Mini Pro 12K

  • URSA Broadcast / Broadcast G2

Pro Tip: If you are hearing a "hum" in your audio, check if the issue persists when the camera is running on battery vs. AC power. If it only happens on AC, the problem might be a ground loop in your power supply rather than a faulty internal XLR cable.

Are you losing audio on just one channel, or are both ports acting up?

These are the best balls ever! We have 2 very active ball loving dogs and these bounce very well and they actually hold up with active play and chewing. They still look brand new after daily use for months!

Finally a ball my power chewers cannot destroy
Size: Medium
I have two dogs, an American Bully and an American Pit Bull Terrier, and both of them love to chew. Most balls last a very short time around here before they are shredded or missing big chunks. This one has actually held up. They chase it, tug on it and sit and chew on it, and it is still in one piece with no pieces breaking off. One of my favorite things is being able to put food inside. I add some kibble or small snacks, and they will happily sit and work on it for a long time. It keeps them busy, gives them something safe to chew, and they get a little reward while they play. When they are done, I just rinse it out and it is ready to go again. If you have strong jawed dogs that usually destroy toys, this ball is worth trying. Mine really enjoy it and I feel better knowing they finally have a ball that can keep up with them.

My dog LOVES this ball
Size: Medium, Size: Medium
Does your dog destroy tennis balls in seconds? Yes? Then your dog NEEDS this ball! It's squishy like a tennis ball, fits in ball launchers (even the cheap ones) and bounces when it hits the ground. My dog has been literally playing with this ball all day and not a single mark on it! The only bad thing is that it does not float. Definitely worth the money! Put it in your cart!

Perfect for ball demolishers
Size: Medium
The dogs love the chuck it brand. I don’t know what it’s made of but they go crazy over them. Will not play with another ball. Wonder if it’s “laced” with an addictive scent. Have pits. Very durable. Not able to chew to pieces. Last for about 6 months before there is a small break. I keep a back up because when the ball goes missing the house is in chaos. 😆 🤪
