3. Setup
3.1 Power Connection
- Connect the provided 6ft power cord to the AC power input on the rear panel of the ATEM 1 M/E Constellation 4K.
- Plug the other end of the power cord into a grounded electrical outlet.
- Ensure the power source meets the voltage requirements specified for the device.
3.2 Video Input Connections
The switcher features 10 standards-converted 12G-SDI inputs. These inputs automatically detect and convert various video formats, simplifying multi-source setups.
- Connect your SDI video sources (e.g., cameras, playback devices) to the "SDI INPUTS" BNC connectors on the rear panel.
- Ensure that the SDI cables are of appropriate quality and length for 12G-SDI signals to maintain signal integrity.
- For reference synchronization, connect a black burst or tri-sync signal to the "REF IN" BNC connector.
3.3 Video Output Connections
The ATEM 1 M/E Constellation 4K provides 6 independent assignable 12G-SDI outputs and a dedicated Multiview SDI output.
- Connect your program output, auxiliary feeds, or other desired video signals to the "SDI OUTPUTS" BNC connectors.
- Connect a monitor to the "MULTIVIEW" SDI output to view all inputs, program, and preview feeds simultaneously.
- For webcam functionality, connect a USB-C cable from the "USB Type-C" port to a computer.
3.4 Audio Connections
The switcher includes balanced analog audio inputs and talkback capabilities.
- Connect balanced audio sources to the "ANALOG AUDIO IN" 1/4" TRS inputs (CH1, CH2) on the rear panel.
- For talkback communication, connect a 5-pin XLR headset to the "Talkback Connection" on the front panel.
3.5 Network Connection
Connect an Ethernet cable from your network switch or computer to the "CONTROL" RJ-45 port on the rear panel for remote control via ATEM Software Control.
4. Operation

- CUT Button: Performs an instant, hard cut transition between the preview and program sources.
- AUTO Button: Executes a smooth, timed transition (e.g., dissolve, wipe) between the preview and program sources, based on the selected transition type and duration.
4.2 Using the LCD Display and Rotary Knob
The integrated LCD display provides visual feedback and access to various switcher settings.
- MENU Button: Press to access the switcher's menu system on the LCD.
- Rotary Knob: Turn to navigate through menu options and adjust parameters.
- SET Button: Press to confirm selections or enter sub-menus.
- LOCK Button: Engages or disengages the control panel lock to prevent accidental changes.

- For stubborn marks, lightly dampen the cloth with water; avoid harsh chemicals or abrasive cleaners.
6. Troubleshooting
6.1 No Power
- Verify the power cord is securely connected to both the switcher and the electrical outlet.
- Check if the electrical outlet is functional by plugging in another device.
- Ensure the correct fuse is installed and not blown (refer to the fuse compartment on the rear panel).
6.2 No Video Output
- Confirm that video sources are properly connected to the SDI inputs and are active.
- Check that the correct input is selected on the program bus.
- Verify that output monitors are correctly connected to the SDI outputs and are powered on.
- Ensure that the output format of the switcher matches the capabilities of your display devices.
6.3 Network Connection Issues
- Ensure the Ethernet cable is securely connected to the "CONTROL" port and your network.
- Check network settings on your computer and the switcher to ensure they are on the same subnet.
- Restart the ATEM Software Control application and the switcher.
