The Blackmagic Design Spares - UltraStudio 4K 2 - PCB Rear is the secondary internal circuit board for the second-generation UltraStudio 4K. While the Main PCB handles the heavy video processing, the Rear PCB acts as the physical interface and signal distribution hub for the vast majority of the unit's professional inputs and outputs.

High-Density I/O Management

The UltraStudio 4K 2 is a 1RU rackmount device known for its extensive connectivity. Because the rear of the unit is packed with connectors, this PCB is specifically engineered to manage signal integrity across multiple formats. Replacing this board is the primary fix for units with physically broken BNC connectors, "fried" ports due to static discharge, or signal loss on specific analog or digital lines.

The Rear PCB typically supports:

  • 6G-SDI Inputs/Outputs: Providing the physical BNC paths for SD, HD, and Ultra HD up to 2160p30.

  • HDMI Connectivity: Houses the HDMI input and output ports for connecting to monitors and consumer cameras.

  • Analog Video: Managing the Component, Composite, and S-Video breakout connections.

  • Audio Interfaces: Handling the balanced XLR analog audio, AES/EBU digital audio, and the RS-422 deck control port.

Bridge to the Main Logic

The Rear PCB is connected to the Main PCB via a series of high-speed ribbon cables or a bridge connector. It acts as the "gatekeeper," receiving raw electrical signals from the outside world and prepping them for the FPGA processors on the main board. It also contains the necessary protection circuitry (such as ESD diodes) to prevent minor electrical surges from the cables from reaching the more expensive main processing chips.

Identifying the Generation 2

It is critical to ensure you are sourcing the "Generation 2" version of this spare. While the original UltraStudio 4K and the UltraStudio 4K 2 look nearly identical from the outside, the internal PCB architecture changed to accommodate higher bandwidths and improved 6G-SDI performance.

  • Gen 1: Often limited in 4K frame rates and uses older internal bus architecture.

  • Gen 2: Features updated 6G-SDI components for more reliable 4K/UHD 30p workflows.

Key Features

  • Genuine Blackmagic Component: Guaranteed to fit the 1RU UltraStudio 4K 2 chassis perfectly.

  • Modular Repair: Allows for the replacement of damaged ports without discarding the expensive main processing board.

  • Signal Shielding: Designed to minimize crosstalk between the high-frequency digital SDI signals and the sensitive analog audio/video paths.

  • Ruggedized Mounting: Built with reinforced soldering points for the BNC and XLR connectors to withstand frequent cable changes.

Technical Installation Note

Replacing the Rear PCB is a labor-intensive process that requires a near-total teardown of the unit.

  • Connector Alignment: When installing the new board, all BNC, XLR, and HDMI ports must be perfectly aligned with the rear metal faceplate before the internal screws are tightened.

  • Ribbon Cable Seating: You must ensure that the high-density cables connecting the Rear PCB to the Main PCB are seated squarely; a slight tilt in these cables can cause intermittent signal "glitches" or total device failure.

  • Port Nut Tension: Ensure the hex nuts on the BNC connectors are tightened correctly to provide a solid ground to the chassis, which is essential for reducing signal noise.

Definitely not indestructable
Size: Medium/Large, Color: Dog Ness Monster - Large, Size: Medium/Large, Color: Dog Ness Monster - Large
I have a 1-year-old toy fox terrier (Rocky, pictured). He has been chewing on this toy for seven months now; it is one of his favorites. He has been unable to seriously damage the "ocean" portion of this toy, but as you can see from the provided image, the sea serpent has not faired that well. It is missing its snout and smaller portions of the humps. My guess is that the advertiser images showing much larger dogs with "like new" versions of the toy are just that...NEW AND UNCHEWED. I have not had to clean up bits of this toy from my floor, so I assume Rocky has been swallowing them. My hope is that the yellow material of the serpent is not chemically dangerous when exposed to digestive fluids. Rocky easily destroys plush toys in a matter of days if not hours and, consumed pieces of a small microfiber blanket that he liked to toss around and play tug-of-war with (past tense as he destroyed it and has since been trashed after I began finding feces-stained undigested pieces of it lying around). Since this toy has survived seven months and has remained recognizable, I have to agree it is durable. Just beware, if my small toy fox terrier can damage the toy as pictured, expect your large breed chewer to do similar or worse damage. Also, the toy is very heavy! When Rocky drops it down a flight of stairs, it makes a MAJOR thud at the bottom, and sometimes makes me wonder if it might crack the large tile at the bottom. I cautiously recommend the product. Note the yellow frisbee in Rocky's picture. It is only a few months old and surprisingly has not suffered any chew damage despite substantial abuse. It appears to bend in the wind like a proverbial reed, evading damage by yielding to pressure.

Dog loves it! For tough chewers for sure
Size: Medium/Large, Color: Dog Ness Monster - Large, Size: Medium/Large, Color: Dog Ness Monster - Large
Dog absolutely loves it, he’s super rough on all of his toys they usually last about 10 minutes bore they are torn to shreds. It’s lasting through his chewing so I’m happy. It’s also super cute.

Cute toy, dog really likes it. I had my doubts when I pulled it out, and honestly so did she, but the soft part bounces, so that got her going. We've had it for about a week. My dog is ~70 lbs and a moderate chewer, and this monster still gets regular play and is holding up well.

Great toys for aggressive chewers
Size: Medium/Large, Color: Turkey Day Drumstick - Large
These are great toys they last a while they are destroyed after a while but both dogs are aggressive chewers but they last about a year and a half. And they are go to toys they have one that is a shark mouth and they love it I have bought 4. (two of them the pups lost ).

Durable and Fun, Just Gets a Bit Rough
Size: Medium/Large, Color: Chopper - Large
This is a really good toy overall, especially if you have dogs that love to chew. My dogs were immediately into it—they play with it nonstop, toss it around, and stay entertained for a while, which I love. It definitely holds up better than most toys we’ve tried. The only reason I’m giving it 4 stars instead of 5 is because over time it does start to fray a bit and gets a little rough, especially with heavy chewing. It’s not completely indestructible, but it still lasts longer than a lot of other toys. Overall, still a great buy and I would recommend it if your dogs need something tough but fun!
