5. Installation and Connection

Follow these steps to set up your HDMI Matrix Switch:

1. Power Off Devices: Ensure all HDMI source devices and display devices are powered off before making connections.
2. Connect HDMI Sources: Connect up to four HDMI source devices (e.g., Blu-ray player, game console, PC) to the IN-1, IN-2, IN-3, and IN-4 ports on the matrix switch using high-quality HDMI cables.
3. Connect HDMI Displays: Connect your two HDMI display devices (e.g., TV, projector) to the OUT-A and OUT-B ports on the matrix switch using high-quality HDMI cables.
4. Connect Audio Outputs (Optional): If you wish to extract audio, connect your audio receiver, soundbar, or headphones to the SPDIF-A/B or L/R-A/B ports as needed.
5. Connect Power: Connect the 5V DC power adapter to the DC-5V port on the matrix switch, then plug the adapter into a power outlet.
6. Power On Devices: Power on the HDMI matrix switch, then power on your display devices, and finally your source devices.

This diagram demonstrates how to connect up to four HDMI source devices (e.g., game consoles, HD players) to the matrix switch, and then connect two display devices (TVs) to the outputs. It also shows the DC 5V power input.

6. Operating Instructions

6.1 Switching Inputs

You can switch between HDMI inputs using two methods:

• Manual Switching: Press the 'Switch-A' or 'Switch-B' buttons on the front panel to cycle through the inputs for the respective output.
• Remote Control: Use the included IR remote control to directly select inputs for Output A (OUT A buttons) or Output B (OUT B buttons). The remote allows selection of inputs 1 through 4 for each output.

Inputs can be switched either by pressing the physical buttons on the device or conveniently using the included IR remote control from a distance of up to 5 meters.

6.2 Matrix Mode vs. Splitter Mode

The device can operate in two primary modes:

• Matrix Mode: Allows you to display different HDMI sources on different outputs simultaneously (e.g., Input 1 on Output A, Input 2 on Output B).
• Splitter Mode: Allows you to display the same HDMI source on both outputs simultaneously (e.g., Input 1 on Output A and Output B).

The image visually explains the two primary operating modes: Matrix Mode, where different inputs can be routed to different outputs, and Splitter Mode, where a single input is duplicated across both outputs.

6.3 EDID Settings

The EDID (Extended Display Identification Data) settings determine the video and audio capabilities reported to the source device. This ensures optimal compatibility. The EDID setting for Output A will be applied. If two displays require different EDID settings, select an EDID mode that is compatible with both displays.

To change the EDID setting, adjust the DIP switches on the front panel according to the table below. After changing EDID settings, restart the HDMI Matrix Switch for changes to take effect.

This image highlights the EDID DIP switches on the device and provides a table detailing the 16 different EDID settings, allowing users to configure audio and video output preferences (e.g., 1080P, 4K30, 4K60, Dolby/DTS 5.1, 2CH Audio).

6.4 Audio Extraction

The matrix switch can extract audio from the HDMI input signal and output it through dedicated audio ports:

• SPDIF Optical Output: Connect to a soundbar, AV receiver, or amplifier for multi-channel audio (LPCM/Dolby/DTS 5.1).
• 3.5mm L/R Stereo Output: Connect to headphones or stereo speakers for 2-channel audio.

The device supports audio extraction via SPDIF optical output for soundbars or amplifiers, and a 3.5mm L/R stereo headphone output for headphones or stereo speakers.

7. Maintenance

• Keep the device in a cool, dry, and well-ventilated area.
• Avoid exposing the device to direct sunlight, high temperatures, or humidity.
• Clean the device with a soft, dry cloth. Do not use liquid or aerosol cleaners.
• Ensure proper cable management to prevent strain on ports.
• It is recommended to power off the unit when not in use for extended periods to prolong its lifespan.

8. Troubleshooting

• No Picture/Signal:
  • Ensure all HDMI cables are securely connected.
  • Verify the correct input is selected on the matrix switch for the corresponding output.
  • Check the EDID settings. Try a different EDID mode (e.g., TV Copy or a lower resolution) if your display or source has compatibility issues. Remember to restart the switch after changing EDID.
  • Try connecting the source directly to the display to rule out cable or source issues.
  • Ensure the power adapter is correctly connected and the device is powered on.
• No Audio/Poor Audio Quality:
  • Check audio cable connections (SPDIF, 3.5mm L/R).
  • Verify the audio settings on your source device and display.
  • Adjust EDID settings to ensure the desired audio format is selected (e.g., Dolby/DTS 5.1, 2CH Audio).
  • Ensure the volume on your audio receiver/speakers is not muted or too low.
• Remote Control Not Working:
  • Ensure there are no obstructions between the remote and the IR receiver on the switch.
  • Check if the remote control batteries need replacement.
  • Ensure you are within the effective range (typically 5 meters).
• Intermittent Signal/Flickering:
  • Use high-quality, certified HDMI cables, especially for 4K resolutions and longer lengths.
  • Reduce cable length if possible.
  • Try a different EDID setting.
  • Ensure the power supply is stable.
