The Blackmagic Design UltraStudio 4K Extreme 3 - PCB Main is the primary logic board for Blackmagic’s most powerful rackmount capture and playback solution. Given the "Extreme" nature of this hardware, the Main PCB is a massive, high-density board engineered to handle 12G-SDI, HDMI 2.0, and high-speed PCIe or Thunderbolt 3 data streams simultaneously.

Enterprise-Grade Processing Power

The Main PCB acts as the heart of the UltraStudio 4K Extreme 3, managing the heavy lifting for 4K DCI and Ultra HD workflows up to 60p. It is specifically designed to support:

  • 4:4:4:4 and 12-bit RGB Support: The board handles extremely high color precision for high-end color grading in DaVinci Resolve.

  • Hardware Codec Support: It features onboard processing for hardware-accelerated encoding/decoding, reducing the CPU load on the host workstation.

  • Stereoscopic 3D: Manages the dual-stream SDI connections required for high-frame-rate 3D capture and playback.

Extensive I/O Integration

Because the UltraStudio 4K Extreme 3 is a 2RU rackmount unit, the Main PCB is much larger than those found in the "Mini" or portable units. It serves as the mounting point for a vast array of professional connections:

  • Dual 12G-SDI Inputs/Outputs: For quad-link or dual-link 4K configurations.

  • HDMI 2.0 In/Out: Providing the full 18Gbps bandwidth required for 4K 60p HDR monitoring.

  • Analog Video I/O: Component, Composite, and S-Video processing logic.

  • Thunderbolt 3 & PCIe: The board manages the high-speed bridge to the host computer, whether via the 40Gbps Thunderbolt 3 port or the external PCIe Gen 3 connector for dedicated workstation integration.

Audio and Sync Management

The Main PCB is responsible for more than just video; it handles a massive amount of audio and sync data:

  • AES/EBU and Analog Audio: Manages the high-quality A/D and D/A conversion for the balanced XLR inputs.

  • Timecode and Reference: Houses the logic for LTC timecode and tri-sync/black burst reference inputs, essential for broadcast facility integration.

  • RS-422 Deck Control: Includes the serial control logic for interfacing with professional broadcast decks.

Key Features

  • Genuine High-Performance Spare: Designed specifically for the "Extreme 3" iteration (Thunderbolt 3 version).

  • Broadcast Reliability: Built with high-tolerance components intended for 24/7 operation in broadcast environments.

  • Multi-Format Support: Pre-configured to work with the full spectrum of SD, HD, Ultra HD, and 4K DCI formats.

  • PCIe Bridge Logic: Specifically optimized for low-latency communication with the host OS.

Technical Installation Note

The UltraStudio 4K Extreme 3 is a complex, multi-component piece of hardware. Replacing the Main PCB is a significant undertaking:

  • Internal Cable Density: The unit contains numerous internal ribbon cables and power looms connecting the front panel, power supply, and rear I/O. These must be meticulously labeled and reconnected.

  • Thermal Considerations: The Main PCB features large heat sinks for its processing chips. Ensure there is no obstruction to the internal fans after the board is seated.

  • Firmware Sync: After installation, the board may require a firmware update via the Blackmagic Desktop Video Utility to ensure it matches the software version on the host computer.

  • Static Hazard: Due to the high cost and complexity of the board, an ESD-safe workspace is non-negotiable during installation.

These babies are sturdy.
You could put your fattest counsin on these babies and they wouldn't break. Easy to build, everything that you needed was included. And I love the way they look. I accidentally matched my new bed frame to them. The lights are sticky LED light strands. They aren't sticky enough. But I dont care I didnt buy it for the lights.

Manufactured wrong
Double check the mounting holes BEFORE you assemble! I got the whole thing put together, and then realized the left side bracket was incorrectly manufactured- the mounting hole is on the front of the unit instead of the back, so I can’t actually hang it on the wall. The assembly was easy, though.

Solid Floating Shelves 🛠️🏠
Color: Black, Number Of Shelves: 4, Size: 15.7in
I have installed four sets of the black floating shelves in my office. They are made of high quality materials, featuring a sophisticated black woodgrain finish with a natural texture. Supposedly, each unit can handle up to 22 pounds, though I would not recommend testing that limit with your vintage bowling ball collection if you value your flooring. They are awesome. The value is good for a set of two. Each shelf measures 22x7x1 (56x17x3 cm) inches, providing a decent amount of storage for books or decor. The installation was straightforward since the hardware for multiple wall types was included. They work well in the kitchen for spices or in the bedroom for personal belongings. One tip for a secure fit: use a level during installation and make sure the bracket is flush against the wall before sliding the shelf on, or your photos might look like they are sliding off a mountain 📐 These shelves offer a clean, modern look and stay stable once mounted correctly. They are a practical choice for adding functional display space to any room 🖼️

Good looking shelves and easy install - skip the included drywall anchors
Color: Black, Number Of Shelves: 2, Size: 22in
I installed these shelves in a bedroom to get things off my dresser and some decor. Once mounted they look really nice. The black finish looks clean and modern and they blend in well with the room. Installation was pretty straightforward. The metal bracket mounts to the wall first and then the shelf slides over the bracket. As long as you take your time lining things up it’s a simple project. One thing I strongly recommend is not using the white plastic self-drilling drywall anchors that come with the kit. I’ve used that style before on other projects and they tend to strip out easily and leave larger holes in drywall. I used better anchors instead and the shelves mounted much more securely. The rest of the hardware worked fine and once installed the shelves feel solid and hold items well. Pros - Clean modern look - Easy installation - Feels solid once mounted - Good size for books or decor Cons - The small level included isn’t very accurate — use your own level - One of the metal brackets was slightly bent out of the box but straightened out easily Helpful tip: Use your own level and better drywall anchors if you have them. It makes installation easier and the shelves will mount much more securely. Final thoughts: For the price these are nice looking floating shelves that install easily and work well for light storage and decor.
