Blackmagic Design Spares - ATEM 2M/E Prod Studio 4K - PCB SDIThe Blackmagic Design Spares ATEM 2 M E Production Studio 4K PCB SDI is the specific I O interface board (often referred to as the "SDI Board" or "Connector PCB") that populates the rear of the unit. In the ATEM 2 M E 4K architecture, this board is distinct from the Main processing logic, focusing entirely on high frequency signal distribution for the 20 SDI inputs and various SDI outputs. Because this board handles 6G SDI or 12G SDI signals

The Blackmagic Design Spares - ATEM 2 M/E Production Studio 4K - PCB SDI is the specific I/O interface board (often referred to as the "SDI Board" or "Connector PCB") that populates the rear of the unit. In the ATEM 2 M/E 4K architecture, this board is distinct from the Main processing logic, focusing entirely on high-frequency signal distribution for the 20 SDI inputs and various SDI outputs.

Because this board handles 6G-SDI or 12G-SDI signals (depending on the specific hardware revision), it is a high-precision component where the physical layout of the traces is critical to preventing signal "jitter" or data loss.


Core Responsibilities

  • SDI Input Bank: Manages the 20 physical BNC inputs. It handles the signal equalization required to "clean up" incoming video that has traveled over long cable runs.

  • Return/Aux Outputs: Houses the BNC connectors for the 6 Aux outputs, Program out, and Preview out.

  • Signal Re-clocking: Every port on this board has a dedicated "Re-clocker" chip. This ensures that the output signal leaving the switcher is as strong and stable as the original source.

  • 6G/12G-SDI Support: Manages the massive bandwidth required for Ultra HD 4K video. If this board fails, you may see signals working in 1080p but failing immediately when the switcher is set to a 4K resolution.


When to Replace the SDI PCB

  • "Dead" Port Rows: If a horizontal row of BNC ports (e.g., all the even-numbered inputs) stops working, the power rail or controller chip on the SDI board has likely failed.

  • Physical BNC Fatigue: The SDI PCB is the most common part to break due to mechanical stress. If a BNC connector is "spinning" or has been pushed into the chassis, the solder pads on the PCB are likely torn.

  • Sparking/Static Damage: SDI ports are "hot-pluggable," but a significant voltage difference between a camera and the switcher can fry the input protection diodes on this specific board.

  • BNC Center-Pin Damage: If a user accidentally inserts a damaged SDI cable and snaps the "female" center pin of the BNC port, the entire SDI board is usually replaced to ensure broadcast reliability.


Technical Installation Note

Repair Level: 4 (Advanced). 1. The Nut Marathon: You must remove the silver hex nuts and washers from all 20+ SDI connectors on the rear. Use a proper $14\text{mm}$ socket. Pro-Tip: Do not use pliers, as you will scratch the black paint of the chassis, which can devalue the unit for resale.

2. Ribbon Cable Interconnects: The SDI PCB connects to the Main PCB via several high-density ribbon cables or "flex-circuits." These are extremely fragile. Ensure you unlatch the "ZIF" (Zero Insertion Force) connectors before pulling the cables.

3. BNC Alignment: When sliding the new board in, all 20+ BNC ports must line up with the back panel holes simultaneously. It is a tight fit. If it doesn't slide in easily, check that a ribbon cable isn't pinched between the board and the chassis.

4. Static Control: This board is covered in sensitive CMOS chips. Wear an ESD wrist strap; one static pop can kill an input before you even finish the repair.


Diagnostic: SDI Board vs. Main PCB

  • It's the SDI Board if: The ATEM Software Control shows that the switcher is alive, the Multiview UI is visible, and the internal Media Pool graphics can be keyed over "Black," but your external SDI cameras show no signal.

  • It's the Main PCB if: The software won't connect, or the entire Multiview output is missing/garbled.

Expert Advice: If you are replacing this board due to physical damage, consider installing a 1RU or 2RU BNC Patch Panel in your rack. By plugging your cameras into a patch panel instead of directly into the SDI PCB, you transfer the "wear and tear" to an inexpensive patch cable rather than the expensive internal SDI board.

Are you experiencing a loss of signal across all ports, or is one specific BNC connector physically damaged?

Carefully measure your size
Size: Large, Color: Ocean Blue
So difficult to get over my shoulders I guess it's a little small for me. Comfortable but I don't want to take it off or put it on

Larger than life
Size: X-Large, Color: Ocean Blue
The fit is large! So go down a size. It’s soft and seems like good quality, but absolutely huge

Very good quality sports bra.
Size: Large, Color: Navy
Very good sports bra. It is high quality and made well. It is a full coverage bra which gives it good support but also makes it a little hot especially in warmer temperatures but at the same time it is very nice for cooler temps.

Supportive and Comfortable but Size Down!
Size: X-Large, Color: Navy
Very supportive for the big chested girlies! Material is comfortable and sweat wicking. I’d recommend sizing down for a snug fit.

Nice fabric, comfortable, easy maintenance
Special Size: 27.5" Full Length, Size: Large, Color: Taupe, Special Size: 27.5" Full Length, Size: Large, Color: Taupe
I ordered a medium and they’re actually a size large. And they are just too large. I should’ve gotten the small, as recommended I thought I was ordering medium and I think I would’ve been OK with a medium, but where I usually wear a small and they sent me a large. It was just ridiculously large. They are lightweight and they are warm. I’m a senior and I’m thin so I get cold very easily especially in early morning and evening, so I like to wear them in the morning for my walks/yoga , they also work nicely under a longish skirt so it’s not so sheer… will definitely get more but will go with the small size. Just for reference, I’m 5 foot seven I usually wear a small or a size 5/6 usa size so these were too large, particularly in the waist just overall they were too large, but I think even if I got a small size they’re still gonna be kind of large in the stomach. I have an hourglass shape just for reference, but they are very comfortable, and I love the fabric. I am keeping them because I like the fabric and I really need them. I just will not wear them out of the house right now because they’re not fitting properly but next go round we’ll get the right size. Price was right they were having a sale so it was a bit of an impulse buy. But hello it was only 10 bucks! so that’s why it’s not worth sending it back for me. Overall, very nice quality and would recommend. Cats like the fabric too! 😸
