The Blackmagic Design Spares - ATEM Television Studio Pro 4K - Main PCB is the primary processing motherboard for the 12G-SDI version of the switcher. While it shares a chassis design with the HD model, the internal electronics are significantly more robust to handle the massive data throughput of Ultra HD 2160p60.

In the 4K model, the Main PCB acts as the foundational logic board, coordinating with the Mezzanine board (which handles the physical I/O) to process high-resolution video with minimal latency.


Core Responsibilities

  • System Logic: Acts as the "General" for the unit, managing communication between the control panel buttons, the network (Ethernet), and the video processing engines.

  • UHD Effects Engine: Processes the 4K DVE, Chroma Keyers, and Media Pool graphics.

  • T-Bar & Control Interface: Interprets the analog signals from the physical T-Bar and translates them into digital transitions on the Program out.

  • Multiview Logic: While the Mezzanine board provides the SDI signal, the Main PCB handles the "windowing" and UI overlay of the Multiview.

  • Power Distribution: Regulates the high-amperage power required by the UHD processing chips, distributing it to the fans and peripheral boards.


When to Replace the Main PCB

  • Total Boot Failure: The unit is plugged into a known working power source, but no lights appear on the buttons and the cooling fans do not spin.

  • Network Loss: The Ethernet port is physically intact, but the switcher refuses to appear on the network or accept a static IP, even after a firmware recovery.

  • Control Panel "Ghosting": The switcher functions fine via the ATEM Software Control, but the physical buttons on the desk are unresponsive or flickering, and the Control Panel PCB has already been ruled out.

  • Memory Corruption: The "Media Pool" consistently fails to hold graphics, or the switcher "forgets" its settings every time it is power-cycled.


Technical Installation Note

Repair Level: 5 (Expert). This is a complete "gutting" of the console.

  1. Dual-Board Separation: In the 4K model, you must first remove the Mezzanine PCB that sits on top of the Main PCB. This requires extreme care to avoid bending the high-density interconnect pins that marry the two boards.

  2. Thermal Management: The 4K Main PCB generates significant heat. You must ensure the main FPGA is clean of old residue and that new thermal pads (not just paste) are used to bridge the gap between the chips and the metal chassis heatsink.

  3. T-Bar Recalibration: After swapping a Main PCB, you may find the physical T-Bar doesn't reach 100% of the transition. You will need to perform a calibration routine (usually found in the ATEM Setup Utility or a specific button-hold sequence) to sync the T-Bar to the new board.

  4. Firmware "Marriage": Once installed, the new board must be updated via USB. The software will detect a hardware mismatch and prompt you to "Update." This process "marries" the new PCB to the existing hardware IDs of the I/O and Control boards.


Diagnostic: Main vs. Mezzanine vs. PSU

Before committing to the expensive Main PCB, use this checklist:

  • No Lights / No Fans: Likely the Internal Power Supply Module.

  • Lights On / Fans On / No SDI Inputs: Likely the Mezzanine PCB.

  • Lights On / No Software Connection / No Multiview UI: This is a Main PCB failure.

Expert Advice: The ATEM TV Studio Pro 4K is notorious for running hot. If you are replacing a Main PCB that "fried," consider upgrading your rack ventilation. Heat is the #1 killer of the FPGAs used on these boards; keeping the internal fan clear of dust is the best way to avoid having to buy this spare again.

Is the console failing to power on entirely, or are you just losing the connection to your computer?

Fantastic throwing aid!
Very well made, great quality and doesn't feel cheap at all. It's thick, not flimsy or fragile so you can really swing it to launch a ball. Saves my body that I don't have to bend over to pick up the ball anymore, and saves my shoulder that I don't have to hurl the ball anymore. Another bonus is you don't have to touch a slobbered, soggy ball, or a ball covered in dirt. The foldable design is fantastic because I walk everywhere with my dog and don't want to carry around a long stick that's awkward to hold. This folds down small enough that I can securely put it in the back pocket of my jeans without worrying about it falling out. The thing I love most about it is there's a elastic loop at the end so when you fold it you can latch it securely. This small detail is outstanding because I can also hang it on the strap of my sling bag and with the loop secured it will not slip off the strap. This product is so well made and thought out overall.

Excellent toy for play
My dog would play all day if I threw the ball to him. He loves this even though he's 12. The scooped end allows you to pick up the ball without touching it. After a few runs it's covered in dog slobber. So that's a major plus for me! Also, some health issues affect my walking and bending at times. This helps with the bending. This is a great game to play with your favorite friend!

Your high-energy dog will love it!
Why did I wait so long to get one of these?!? I am the stereotypical throws-like-a-girl person, and my dog really needs to have an option that forces her to run far and fast. This is it. I can get that ball half a soccer field away at a minimum if I want. The ball is super bouncy, which adds an element of fun to her attempts to tame it and bring it back. Super worth the money (which wasn't much!). I've never had one of these before, so can't compare to the non-folding version. This one is easy to carry and fits in a drawer for storrage. No way you can fit it in a pocket, especially if you have a phone in one and dog treats in the other.

Great usability
I prefer this version over the non-foldable stick, as this one I can fit into my bag and carry it out easily. Great size and has a locking feature to prevent it from folding up when throwing. Highly recommend, my dogs love fetch and it is hard to chew if they get their hands on it.
