Blackmagic Design Spares - ATEM 4M/E BCast Studio 4K - PCB MezzThe Blackmagic Design Spares ATEM 4 M E Broadcast Studio 4K Mezzanine PCB is a specialized high density interface board for the "top of the line" 2RU rack mount switcher. Because this switcher handles 20 inputs of 12G SDI and supports frame rates up to 2160p60, the data throughput is too massive for a single circuit board. The Mezzanine board acts as the "Input Output Engine," sitting directly atop the Main PCB to handle the physical physical signal

The Blackmagic Design Spares - ATEM 4 M/E Broadcast Studio 4K - Mezzanine PCB is a specialized high-density interface board for the "top-of-the-line" 2RU rack-mount switcher.

Because this switcher handles 20 inputs of 12G-SDI and supports frame rates up to 2160p60, the data throughput is too massive for a single circuit board. The Mezzanine board acts as the "Input/Output Engine," sitting directly atop the Main PCB to handle the physical physical signal conditioning for the massive array of BNC ports.


Core Responsibilities

  • 12G-SDI Bank Management: Specifically handles the 20 inputs and the multiple Program/Aux outputs. Each port has dedicated 12G-SDI re-clocking to ensure signal integrity over long cable runs.

  • Standards Conversion: In the Broadcast Studio 4K model, the Mezzanine board contains the hardware that allows every single input to have its own standards converter. This allows you to plug in a mix of HD, Ultra HD, and different frame rates simultaneously.

  • Signal "Sandwich" Interconnect: It passes processed video data down to the Main PCB (where the 4 M/E rows and 16 Keyers are calculated) via high-speed, multi-pin board-to-board connectors.


When to Replace the Mezzanine PCB

On this professional-grade unit, the Mezzanine board is often the part that "takes the bullet" for the rest of the system during electrical mishaps.

  • Bank Failure: If a group of inputs (e.g., Inputs 1–10) suddenly goes black while the rest of the switcher functions, a localized power regulator or controller chip on the Mezzanine board has likely failed.

  • Sync/Conversion Errors: The switcher connects to the computer and shows the Multiview, but the inputs show "Unsupported Format" or glitchy video despite the "Standards Conversion" being turned on.

  • BNC Physical Damage: With 20 inputs and over 10 outputs, the BNC connectors are under immense stress in mobile fly-packs. If a connector is sheared off or the internal pin is pushed in, the Mezzanine board is the part that must be replaced.

  • Heat-Related Artifacts: If the video shows "sparkles" or digital noise that only appears after the unit has been on for 30 minutes, the 12G-SDI processing chips on this board are likely overheating or failing.


Technical Installation Note

Repair Level: 5 (Expert). This is a high-risk repair due to the density of the components.

  1. Massive Port Disassembly: You must remove the hex nuts and washers from all 30+ BNC connectors on the rear of the unit. Using a power driver is discouraged as it is very easy to strip the threads or slip and gouge the PCB.

  2. The "Lifting" Danger: The board is connected to the Main PCB by several high-density "mating" connectors. You must lift the board perfectly level. If you tilt the board while lifting, you will bend the pins on the Main PCB, which usually results in needing to replace both boards.

  3. Thermal Pad Criticality: This board generates an immense amount of heat. You must replace all thermal pads (often 10 or more) that sit between the Mezzanine chips and the internal heatsinks. Reusing old, compressed pads will lead to a "thermal runaway" failure of the new board.

  4. Weight & Alignment: The board is heavy and large. When reinstalling, ensure all 30+ BNC ports align with the chassis holes before pressing down on the interconnect pins.


Diagnostic: Mezzanine vs. Main

  • It is the Mezzanine Board if: The ATEM Software Control works, the Multiview UI is visible, but all or most of the SDI Inputs are dead.

  • It is the Main Board if: The unit won't boot, won't connect via Ethernet, or the 4 M/E effects (like the DVEs) are crashing the system.

Expert Advice: Because the ATEM 4 M/E Broadcast Studio 4K is a flagship unit, it is highly sensitive to static. If you are replacing the Mezzanine board, ensure you are working in a climate-controlled, ESD-safe environment. A single static pop to one of the 12G-SDI pins during installation can permanently damage the new board.

Are you losing a specific group of inputs, or is the entire SDI I/O bank unresponsive?

OUTSTANDING
Format: Kindle
This was very, very good. The world is vast and characters are complex. There is a good plot with a whole lot going on. This is well written. Good twists and turns and some heart breaking moments. You will love these characters, they have heart and loyalty. I am hoping that there will be several more books. We've yet to see anything from the Sea Court but only a mention of them here and there. The Wood Court was given a quick couple of scenes, and only as far as some warriors, we've yet to enter their court and the Shadow Court, I'm not sure if they will be a force for good or bad, but they definitely will play a much bigger role moving forward. This is primarily the Ice and Air Courts. Told in multiple views, which I loved, it gives you a chance to see things from different eyes. There's alot of political maneuvering and deception. I loved it and will pick up the next book as it becomes available. If you like The Fae and the courts, you should love this. I think the author has mucn in store for us.

Definitely worth the read!
Format: Kindle
After taking a deep breath and taking in that wicked twist of an ending, I have finally composed myself. My first thought when I started this book was that I love Reyna's character. I was intrigued by her connection with her familiar and the Ruin that is plaguing her land. It came as no surprise that she took her sister's place in an attempt to protect her. When they reach the Air Court everything slows down. This is where it was iffy for me. First of all, I like multiple POV's in books however 7 is a bit much. It starts to interrupt the story line. I felt like I was finally making progress connecting with one character, then it was switched to another person. I felt they all had necessary or pertinent information but not necessarily were they all POV worthy. The only other thing that annoyed me was that Reyna constantly was " trapped." She would rush off without thinking, only to need rescuing. She is brilliant in a fight, but she really doesn't think through anything. Lorcan is amazing. I know he might be on the "bad" list, but his background is so interesting. Eislyn(Reyna's sister) is really so sweet, but calculating. I enjoyed her and Thane's dialogue. The author did an amazing job with the imagery in this book. Everything was so detailed it was easy to fall into the scene. I love unexpected twists and while part of the ending I expected, I wasn't expecting how it took place. All in all, I found it very entertaining and I am very invested in continuing this series. Favorite quotes: "The truth may be twisted but never false." "Who was she if she was not the enemy of the Air Court? What was her purpose of she no longer has that?" "In a war-torn land, love was always a lie."

Great Read!!! Great story!!!
Format: Kindle
The series is long, but Ms. Wolfhart does a fantastic job of weaving this tale while bringing so much to the characters. Surprises and plot twists along the way to keep you intrigued. There is some graphic sex, but is no way the focal point. Grammar was excellent (a rare find with a lot of self publishers) with only a few noted errors. I rarely give 4 stars, let alone 5.

Sadly, DNF
Format: Kindle
I read this thru KU. I LOVED the synopsis. And then I began reading... and it was a DNF at 68% after picking it up and putting it down several times because I really loved the main female character. *****SPOILERS***** Pros: The world is unique, intriguing and fun. The primary female character is bad-a** but not a b*tech or a mary sue. The primary female has depth. I really want to know what happens to her even tho it's been weeks and I don't remember her name. The villains to the point I read are pretty good -- an ever present threat of mysterious and possibly many culprits. Cons: Way, way too many points of view. I stopped counting at 7. It's the prime reason why I don't care about most of the characters or remember their names even when I like them. There's just too many points of view so almost none of the characters have enough book space for the author to properly develop them. This literally killed the book for me. Actually it killed my desire to read. For weeks. The main male is more villain than hero. He agreed to marry the main female then locks her up & eschews her for her sister, all while bad mouthing her as unfit to rule when he never spent any time with her getting to know her. He is actually unfit to rule as he is blind to the woes of his own kingdom and starts off a peace mission to secure a ceasefire through marriage by murdering an inn full of people in her country for no real reason. Plus, he constantly makes promises he does not keep. And it's gross of him to pine for the sister behind the main female's back. ***** As much as I really wanted to see what happened to the main female character, it wasn't enough for me to keep trying to slog thru this book. There was a lot of potential here that just fell short. Hence, 3 stars.

Fae Courts with High Intrigue
Format: Kindle
This book is one that just builds and builds and then surprises you to no end. You may think you know the villains and then you are jolted in another direction. Princess Reyna is a real gem, strong of character, a fierce fighter, and loyal to her family and kingdom. Just when you think she and Lorcan, well you know, the plot is flipped. Can't wait to see where this goes in book two.
