5. Operating Instructions

5.1 Switching Inputs

You can switch HDMI inputs using either the front panel buttons or the IR remote control.

Using Front Panel Buttons:

• Press the Key1 button repeatedly to cycle through HDMI inputs 1-6 for Output 1. The corresponding OUT 1 LED will indicate the selected input.
• Press the Key2 button repeatedly to cycle through HDMI inputs 1-6 for Output 2. The corresponding OUT 2 LED will indicate the selected input.

Using IR Remote Control:

• To select an input for Output 1, press the desired input number button (1-6) under the OUT1 section on the remote.
• To select an input for Output 2, press the desired input number button (1-6) under the OUT2 section on the remote.

5.2 Audio Extraction

The matrix switch can extract audio from the selected HDMI input for each output independently.

• Optical Output: Connect an optical cable from the Optical 1 or Optical 2 port to your audio receiver or soundbar for digital audio.
• R/L Stereo Output: Connect RCA cables from the R/L Out 1 or R/L Out 2 ports to your analog audio system for stereo audio.

5.3 EDID Management

The EDID (Extended Display Identification Data) DIP switches allow you to configure the EDID settings to ensure compatibility between your source devices and displays. Incorrect EDID settings can lead to display issues or lack of audio/video. Refer to the table below for common EDID configurations. It is recommended to try different settings if you encounter compatibility problems.

Note: After changing EDID settings, it is recommended to power cycle the matrix switch and all connected devices for the changes to take effect.

6. Troubleshooting

If you encounter issues with your HDMI Matrix Switch, refer to the following common problems and solutions:

• No Picture/Signal:
  • Ensure all HDMI cables are securely connected to both the source devices, the matrix switch, and the displays.
  • Verify the matrix switch is powered on and the POWER LED is illuminated.
  • Confirm the correct input is selected for the corresponding output on the matrix switch (check front panel LEDs or use remote).
  • Try a different HDMI cable.
  • Adjust the EDID DIP switch settings (refer to Section 5.3) and power cycle all devices.
  • Test the source device directly connected to the display to rule out source or display issues.
• No Audio:
  • Check audio connections (HDMI, Optical, R/L) and ensure they are secure.
  • Verify the audio settings on your source device and display are correctly configured for the output.
  • Adjust the EDID DIP switch settings to ensure the correct audio format is being passed (e.g., 2.0CH, 5.1CH, 7.1CH).
  • Ensure your audio receiver/soundbar is set to the correct input.
• Intermittent Signal/Flickering:
  • Use high-quality, certified HDMI 2.0 cables, especially for 4K@60Hz signals.
  • Ensure cable lengths are within recommended limits for 4K signals.
  • Try power cycling all devices (source, matrix switch, display).
  • Check for electromagnetic interference from other electronic devices.
• Remote Control Not Working:
  • Ensure there are no obstructions between the remote and the IR receiver on the matrix switch.
  • Check and replace the remote control batteries if necessary.
  • Ensure you are pointing the remote directly at the IR receiver.
