Blackmagic Design Spares - ATEM 1M/E Panel - PCB Main Int P/SThe Blackmagic Design Spares ATEM 1 M E Panel PCB Main Internal Power Supply is the critical voltage regulation board found inside the legacy ATEM 1 M E Broadcast Panel. In these professional control surfaces, power is managed in a two stage process. There is an internal AC to DC switching module (the "brick") that converts wall power to a bulk DC voltage, and then this Main Internal P S PCB takes that power and breaks it down into the precise $3.

The Blackmagic Design Spares - ATEM 1 M/E Panel - PCB Main Internal Power Supply is the critical voltage regulation board found inside the legacy ATEM 1 M/E Broadcast Panel.

In these professional control surfaces, power is managed in a two-stage process. There is an internal AC-to-DC switching module (the "brick") that converts wall power to a bulk DC voltage, and then this Main Internal P/S PCB takes that power and breaks it down into the precise $3.3\text{V}$, $5\text{V}$, and $12\text{V}$ rails required to run the thousands of button LEDs, the LCD menu screen, and the main logic processor.


Core Responsibilities

  • Voltage Distribution: Acts as the "clearinghouse" for power, sending the correct wattage to the button banks and the system control section.

  • LED Current Regulation: Ensures that all 20+ buttons have consistent brightness and color without flickering.

  • Noise Filtering: Cleans the electrical signal to prevent "interference" in the digital communication between the panel and the ATEM switcher.

  • Thermal Protection: Includes heat sinks and capacitors designed to handle the 24/7 power draw of a live broadcast environment.


When to Replace the Internal P/S PCB

  • Partial "Blackout": The panel powers on, but only certain sections light up (e.g., the fader works, but the button rows are dead). This usually indicates a failure of one specific voltage rail on the PCB.

  • Random Reboots: The panel "glitches" or restarts during a show, particularly when button brightness is set to high or when many buttons are being pressed simultaneously.

  • "Coil Whine" or Buzzing: High-pitched electrical noise coming from the panel is a sign of failing capacitors on this board.

  • Unresponsive Network: If the power rail for the Ethernet controller is "sagging," the panel might light up but will fail to connect to the switcher.


Technical Installation Note

Repair Level: 3 (Moderate).

  1. Capacitor Discharge: Crucial Safety Step. Unplug the panel and let it sit for at least 15 minutes before opening. The large capacitors on the power boards can hold enough charge to give you a significant shock.

  2. Wiring Harness Orientation: This board is connected via several multi-colored wiring looms. Take a photo before disconnecting. While the connectors are usually keyed, it is easy to snag a wire or pinch a harness during reassembly.

  3. Grounding Standoffs: Ensure every screw is replaced and tightened. These screws often provide the "common ground" for the entire panel; if one is missing, you may experience static or touch-sensitivity issues on the buttons.

  4. Airflow: Check the internal fans while you have the unit open. If the fans are caked in dust, the internal P/S board will overheat, leading to a repeat failure of the new part.


Diagnostic: Internal P/S vs. AC Module

If your panel is completely dead (no lights, no fans):

  • Test the AC Module: Use a multimeter to check the output of the internal "brick." If it is outputting 0V, replace the AC Module.

  • Test the P/S PCB: If the brick is outputting steady voltage (usually $12\text{V}$ or $15\text{V}$) but the panel won't boot, the Main Internal P/S PCB is failing to convert that power for the internal components.

Expert Advice: If you are in a region with inconsistent power (spikes/brownouts), this is the part most likely to fail. Always run your ATEM panels through a high-quality Online Double-Conversion UPS to protect these internal regulation boards from "dirty" power.

Has the panel stopped powering on entirely, or is it just acting erratically during high-intensity use?

Love this! Wish I would know about them sooner. So nice to have power on the top side of the desk.

3 inches plus!
Color: Black, Size: 6FT
It works well BUT you will need a little more than a three inch opening. I ordered this as a replacement for a plain plastic grommet. I had to buy an attachment for my drill to make the hole a tad bigger and smooth out any bumps in the hole.

Quality Product
Color: Black, Size: 6FT
Easy to install and comes pre-wired. This works as advertised and is easy to add to a new furniture build or retrofit into existing furniture.

Great for price
Color: Black, Size: 6FT
Worked great in the predrilled spaces in retail environment on counters. Had to do minor shaving of the existing holes but worked great after that. Only took 3 mins to correct. Well hidden and flush with counter.

Worthless
Color: Black, Size: 6FT
Would leave 0 stars if possible. Things thing f****** suck! Don’t buy them, don’t listen to the positive reviews. Don’t waste your money! They don’t work. Charging ports shut off after you unplug your device. Have to unplug and replug in charging cables and ac plugs everytime you want to use them or else they won’t work. Cheap unreliable product that matches the cheap price. Spend $5 more and get a product that actually works!!!!
