the Blackmagic Design Spares - Camera Studio Pro - PCB Main 4K G2 is the primary motherboard for the second-generation 4K Studio Camera. While it shares the same external housing as the 6K Pro version, the 4K G2 board is specifically engineered for the 4K sensor's data rates and utilizes a different processing architecture.

This board is the "central hub" for the camera, managing everything from the 12G-SDI video output to the remote control logic used in live broadcast environments.


Core Responsibilities

The 4K G2 Main PCB is optimized for low-latency live production:

  • Image Processing: Houses the FPGA that handles the 4K sensor's debayering and applies Blackmagic's Gen 5 Color Science.

  • 12G-SDI & HDMI Output: Manages the high-speed video transmitters that send a $2160\text{p}60$ signal to switchers or monitors.

  • Tally & Talkback Integration: Processes the SDI "Return" feed to extract tally light triggers and handles the 5-pin XLR talkback communication between the operator and the director.

  • Camera Control Protocol: Interprets commands from ATEM switchers (such as iris, gain, shutter, and color grading) and applies them to the sensor and lens in real-time.

When to Replace the Main PCB

As the most expensive electronic component in the camera, replacement is typically only necessary following a catastrophic event:

  • SDI Port "Fried": 12G-SDI ports are sensitive to "ground loops." If a monitor and the camera are powered from different sources and connected via SDI, a voltage spike can burn out the SDI driver chip on the Main PCB.

  • PoE++ Power Failure: If the 10G Ethernet port (used for Power over Ethernet) receives a surge from a faulty network switch, it can destroy the power regulation stage of the motherboard.

  • Total System Hang: The camera is stuck on the splash screen or the 7-inch LCD remains black while the tally light or internal fans are active.

  • Audio/Talkback Failure: If the professional audio inputs (XLR) or the talkback system develop permanent digital noise or stop functioning entirely.


Key Features

  • Genuine OEM Part: Built to the exact specifications of the 4K G2, ensuring 100% compatibility with the camera's internal wiring and cooling system.

  • Dual Power Logic: Supports seamless switching between the 12V DC 4-pin XLR input and the 10G Ethernet PoE++ input.

  • Integrated Connectors: The 12G-SDI, HDMI, and 10G Ethernet ports are surface-mounted directly to the board for maximum signal stability and durability.


Technical Installation Note

DANGER: Level 4 (Expert) Repair. Replacing this board requires a near-total teardown of the unit.

  1. Thermal Interface: The 4K G2 generates significant heat during $4\text{K}60$ operation. You must replace all thermal pads or apply fresh thermal paste to the main processing chips before securing the board to the internal heat sink. Failure to do so will result in the camera shutting down within minutes.

  2. Ribbon Cable Care: The Studio Camera uses several wide, fragile ribbon cables to connect the 7-inch screen and the side control panels to the Main PCB. These connectors have delicate locking tabs that are easily snapped.

  3. Firmware Matching: After installation, you must connect the camera to a computer via USB-C and run the Blackmagic Camera Setup utility. The new board will likely require a firmware update to synchronize with the sensor's calibration data.

  4. Static Discharge (ESD): Always work on an anti-static mat. The high-speed 12G-SDI and 10G Ethernet circuits are extremely vulnerable to static electricity.

Expert Advice: If your camera is unresponsive, always test it with a 4-pin XLR DC power supply before assuming the board is dead. Many "board failures" in the Studio line are actually caused by a network switch failing to provide the full PoE++ wattage required by the 4K G2's high-brightness screen and processor.

Is your camera failing to power on entirely, or is it just failing to output a signal via the SDI ports?

The orange and blue ball is perfect. Once start taken because the because the blue noisy one was a little to easy for my dog to start ripping pieces off. Will say most toys do not survive his chewing.

Aggressive chewer who loves fetch approved!!
Size: Medium, Size: Medium
I highly recommend the Chuck-It brand in general, especially for dogs with an aggressive bite. These balls are awesome and are the most durable balls I’ve bought for my 50 lbs lab mix. He has not been able to break one of them yet and we’ve had a few of the squeaky balls for months. They are a bit pricey but worth it. The one in the pic has been used for months, lives outside and you can see it’s still in great shape.

Good quality dog ball for playing fetch
Size: Medium
My dog and family love these chuck it balls to play fetch with our dog. They are durable and fun. They squeak which is added fun for any dog! Regular tennis balls my dog chews apart and they get pretty gross after playing and being left outside. These can be easily washed off and cleaned. These balls last! Would recommend to anyone with a dog and would purchase again.

My Doxie’s Absolute Favorite Fetch Toy – Who Knew Baby Balls Could Be So Paw-some? I bought these colorful baby balls as a simple toy for my little one, but my furry bay claimed them as his own from day one! These small, bouncy balls are perfect for little dogs – they’re lightweight and easy to grip in his mouth, keeping him entertained for hours. No squeakers or stuffing to destroy, just pure, durable fun. If your pup loves a good game of fetch or just batting things around, these “baby” balls are a steal. Highly recommend!
