Blackmagic Design Spares - ATEM 1M/E Prod Studio 4K - PCB MezzThe Blackmagic Design Spares ATEM 1 M E Production Studio 4K Mezzanine PCB (often called the I O Board) is the secondary circuit board that sits directly above the Main PCB in the 1RU chassis. While the 2 M E and 4 M E models are larger, this 1 M E "4K" variant is incredibly dense.

The Blackmagic Design Spares - ATEM 1 M/E Production Studio 4K - Mezzanine PCB (often called the I/O Board) is the secondary circuit board that sits directly above the Main PCB in the 1RU chassis.

While the 2 M/E and 4 M/E models are larger, this 1 M/E "4K" variant is incredibly dense. The Mezzanine board is responsible for the physical interface of the 10x 6G-SDI inputs, the 1x HDMI input, and the various SDI Program and Aux outputs.


Core Responsibilities

  • High-Speed I/O: Manages the physical 6G-SDI connectors. It handles the signal equalization needed to maintain a clean 4K image over long cable runs.

  • HDMI Interface: Houses the HDMI input circuitry, including the HDCP handshake logic and EDID management.

  • Reference & Sync: Processes the "Ref In" (Genlock) signal, ensuring the switcher is frame-synchronized with your cameras.

  • Data Bridge: Down-converts or prepares the incoming high-bandwidth video data to be sent through high-density connectors to the Main PCB for processing (Keys, DVE, and transitions).


When to Replace the Mezzanine PCB

  • SDI "Blackout" Bank: All inputs (1–10) are dead or showing "No Signal," but the ATEM Software Control shows the unit is connected and healthy.

  • HDMI Port Failure: The HDMI input is physically loose or fails to recognize any signal, while the SDI ports work fine.

  • Physical BNC Damage: If a BNC connector has been sheared off or the internal center pin is broken, the entire Mezzanine board is typically replaced to maintain broadcast reliability.

  • 6G-SDI Jitter: The unit works perfectly in 1080p, but the image "tears" or loses sync as soon as you switch to a 4K Ultra HD video standard.


Technical Installation Note

Repair Level: 4 (Advanced).

  1. The Nut Removal: You must remove the silver hex nuts and washers from all 15+ BNC connectors on the rear. A $14\text{mm}$ deep-well socket is the best tool for this.

  2. Board-to-Board Connectors: The Mezzanine board is joined to the Main PCB via several multi-pin headers. Warning: You must lift the board perfectly vertically. Tilting it during removal can bend the pins on the Main PCB underneath, which is a catastrophic failure.

  3. Thermal Pads: High-bandwidth 6G-SDI chips generate significant heat. You must ensure the thermal pads on the underside of the Mezzanine board are present and making contact with the internal heatsinks/chassis.

  4. Chassis Flex: Because the BNC ports are soldered to the board but poked through the chassis, ensure you don't over-tighten the BNC nuts, which can put "bowing" stress on the PCB.


Diagnostic: Mezzanine vs. Main PCB

  • It's the Mezzanine Board if: You have a Multiview output and the software connects, but your inputs are missing.

  • It's the Main PCB if: The unit won't boot, won't connect to Ethernet, or if the Multiview itself is black or garbled.

Expert Advice: If you are losing signal on just one or two ports, check for "cold solder joints" on the BNC legs where they meet the PCB. Sometimes a simple reflow with a soldering iron can save you the cost of a full replacement Mezzanine board.

Are you seeing a failure on the HDMI input specifically, or are the SDI banks failing to register your cameras?

THE BEST LOTION I HAVE EVER USED
Scent: Sweet Vanilla & Soft Wood, Size: 18.5 Fl Oz (Pack of 1)
THIS WINTER AND HAVING THE HEAT ON HIGHER THEN I NORMALLY DO HAS DONE A NUMBER ON MY SKIN. IT IS SO DRY AND I HAVE TRIED SO MANY THINGS AND NOTHING HAS REALLY WORKED. SO I GAVE IN AND SPENT THE MONEY AND TRIED THIS. I AM SO GLAD I DID. THIS WAS WORTH EVERY PENNY. I LOVED IT SO MUCH I BOUGHT ANOTHER BOTTLE JUST TO HAVE SO I WOULDN'T RUN OUT. I START OUT WITH THE BODY WASH WITH THE OLAY SUPER SERUM BODY WASH AND JUST AFTER ONE WASH MY SKIN WAS MUCH SOFTER AND SMOOTHER. YOU DO NOT NEED A LOT AS IT LATHERS UP NICELY IT SMELLS GREAT AND IT RINSES OFF GREAT LEAVING YOUR SKIN FEELING CLEAN AND SOFT. IT DOESN'T HAVE A STRONG SCENT TO IT WHICH IS FINE . I FOLLOW IT WITH IT WITH THIS SUPER SERUM LOTION JUST TO MAKE SURE THE SKIN STAYS SOFT. THIS LOTION IS SO SOFT AND SILKY. IT ABSORBS QUICKLY INTO YOUR SKIN WITHOUT LEAVING YOUR SKIN FEELING GREASY. IT IS LIGHTWEIGHT AND LEAVES YOU FEELING SOFT WITHOUT THAT DRY CRACKED APPEARANCE. THE SCENT ISN'T VERY STRONG TO ME WHICH IS FINE BECAUSE I WEAR PERFUME SO I DO NOT HAVE TO WORRY ABOUT THE SCENTS MIXING. I DEFINITELY RECOMMEND THIS REGIMEN TO ANYONE SUFFERING FROM DRY SKIN.

4.5/5; Great product, but smells strong
Scent: Sweet Vanilla & Soft Wood, Size: 10 Fl Oz (Pack of 1)
Context: To start off, I should say that I have dry skin. Like, VERY dry skin. In purchasing this item, I wanted a product that I could consistently apply every single day to hydrate my skin. Product: The application of this stuff was like a dream. If you’ve ever tried using ANY sort of lotion (Lubriderm, Cetaphil, etc.) you’d know that usually it leaves that greasy texture on your hands that you have to wash off. This one doesn’t do ANY of that. The cream melts into your skin and absorbs very easily, unlike other lotions. I didn’t need that much to apply to my entire body. The results were great—my skin looked better and felt softer. If there was to be a con, it would be how strong the fragrance of the lotion is. This stuff smells STRONG. It’s not an unpleasant scent, but if you wanted to wear a perfume or body spray along with it, good luck because I can’t see a world where the cream won’t overpower or at least show through your preferred scent. TLDR Overall, good product with dreamlike application, but strength of scent could be dealbreaker for some.

This everyday body lotion is the bomb!
Scent: Collagen, Size: 17 Fl Oz (Pack of 1)
This body lotion is absolutely fabulous! It really does make the skin on my thighs and abdomen look and feel firmer and the skin on my arms, legs, hands, and feet is noticeably softer and more hydrated without looking greasy or feeling sticky. I even use it on my neck and my face, which has tended to be more dry than oily as I've aged. I also really appreciate that the scent is pleasant enough to stand on its own but subtle enough to work well with other fragrances. I don't think that I have ever been this satisfied with a health/beauty product at such an affordable price point. I even purchased a few extra bottles to gift to friends and family.

Wow - my new favorites 💜👍😀
Scent: Retinol, Size: 17 Fl Oz (Pack of 1)
I just purchased this and tried it last night for the first time along with the firming version. I didn't take photos because I was skeptical as a product I had purchased from a different line for more money didn't work. This morning I notice that not only does my skin feel more hydrated but the texture appears more smooth. I recently turned 75 & lost my husband a few months ago and having been a care giver for awhile and put taking care of me aside. These products and body wash are great and I like the fragrance. Please give them a try. To have something show this much difference over night is incredible. They are also affordable which is a plus for me. Thank you Olay.

I've only tried it for the first time, so I can't speak to performance, but I love 5his Product! It isn't greasy, it absorbs quickly & my skin feels much softer. The scent is just beautiful. It's light & not closing like some. Recommend highly.
