Blackmagic Design Spares - ATEM TV Studio HD - PCB Main

R 18,903.70 R 19,898.45
Tax included Shipping calculated at checkout.

The Blackmagic Design Spares - ATEM Television Studio HD - Main PCB is the primary motherboard for the 1RU rack-mount "HD" switcher. In this compact design, the Main PCB acts as the foundational carrier for the entire system, housing the CPU, the central FPGA (the "brain" that performs the actual video cuts), and the power regulation circuitry.

While the Mezzanine PCB handles the physical video inputs, the Main PCB handles the high-level logic and the communication that allows you to control the unit.

Core Responsibilities

  • System Logic & Control: Manages the Ethernet and USB-C ports, allowing the unit to communicate with the ATEM Software Control and the ATEM Setup Utility.

  • Video Processing Hub: Receives raw video data from the Mezzanine board and applies DVE (Digital Video Effects), Chroma Keying, and downstream keys.

  • Media Pool Storage: Houses the flash memory that stores your uploaded stills and graphics.

  • Audio Mixing: Processes the internal Fairlight audio mixer logic, including EQ and Dynamics for all 8 inputs.

  • Internal Routing: Directs signals to the Program (PGM), Preview (PVW), and Multiview (MV) outputs located on the rear of the unit.

When to Replace the Main PCB

  • No Boot / Dead Unit: The power supply is confirmed to be working, but the front panel LEDs stay dark and the unit is not detected via USB or Ethernet.

  • Software Connection Failure: The unit outputs video and the front buttons work, but it is impossible to connect via the network, even after a factory reset or static IP change.

  • "Flash" Failures: The unit frequently crashes, forgets Media Pool graphics, or fails to save "Start-up State" settings.

  • Multiview UI Corruption: You see the video inputs in the Multiview, but the red/green Tally borders or the text labels are garbled or missing (indicating a failure in the UI overlay chip on the Main PCB).

Technical Installation Note

Repair Level: 5 (Expert). Replacing the Main PCB requires a total teardown of the chassis.

  1. Removing the "Sandwich": You must first remove the Mezzanine PCB and the Audio PCB that are plugged into the Main PCB.

  2. Chassis Grounding: The Main PCB is grounded via the screw standoffs. When installing a new board, ensure all screws are tightened to the same tension to avoid "ground loops" which can cause horizontal noise lines in your video.

  3. Thermal Pad Placement: The central FPGA on the Main PCB generates significant heat and usually makes contact with the bottom of the metal chassis via a thermal pad. If this pad is missing or dirty, the new board will overheat and fail within minutes.

  4. MAC Address Change: Note that because the Ethernet controller is on this board, your switcher will have a new MAC address. You may need to update your network router or firewall settings if you use MAC filtering.

Diagnostic: Main PCB vs. Mezzanine PCB

  • Main PCB Failure: The unit won't connect to a computer, won't boot, or the front panel control is completely dead.

  • Mezzanine PCB Failure: The unit boots and connects to the computer fine, but your SDI/HDMI camera inputs are showing up as "Black" or "No Signal."

Pro-Tip: Recovery Mode

Before purchasing a new Main PCB for a "dead" unit, try Recovery Mode:

  1. Unplug the power.

  2. Hold the SET button on the front panel while plugging the power back in.

  3. Connect via USB to a computer running ATEM Setup. If the software asks to "Update," your Main PCB logic is still alive and just had a corrupted firmware—saving you the cost of the spare part.

Are you looking for this part because the unit is completely unresponsive, or are you having trouble with specific video outputs?
