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?

A mind bender.
Format: Paperback
Robert Monroe's story is such a remarkable one that for me it took a few years of pondering and re-reading various accounts of his "journeys" to come to grips with it as a legitimate reality. Since the early 1960's, Monroe carefully logged many hundreds or thousands of out of body experiences and over the years mastered exit techniques and went on to teach them to many students at his institute in Virginia. Far Journeys is a wild ride and was at times difficult to follow due to the many terms RM coined to describe the completely unknown entities and experiences that became routine for him. Once you get accustomed to the vocabulary, the narrative becomes more intelligible. The book is really something of a travelogue to non-physical reality. He is not stopping along the way to explain things to us readers, but leaving the experiences to speak for themselves. In the end, one is left to grapple with the implications of all he is laying out. Is he just completely insane? I don't think that is the case. Monroe was, in my view, a true modern mystic, born into a highly academic and rational Western world. He brought all of his pragmatism and mechanistic views on the world to bear as he wrestled with his remarkable gifts. He is really the heir to Edgar Casey, and in turn any number of mystics from antiquity.

Well written, entertaining - whether this stuff is true or not depends on your opinion.
Format: Paperback
I loved Monroe's first book. *This* book is entertaining, although annoying at times trying to figure out who's talking. I'm silent on whether I believe Monroe's fantastic stories. But if you're okay with that risk, I'd recommend this for both entertainment & perhaps to help unleash some creativity in your self.

Changed forever
Format: Kindle
We become so mired in our subjective “reality”. I find it truly beneficial to have a different, perhaps more objective perspective. I hope this enables me to make necessary changes to my journey before its conclusion.
