6. Setup
Follow these steps to set up your HDMI Matrix Switch Splitter:
- Power Off Devices: Ensure all source devices (e.g., Blu-ray player, game console) and display devices (TVs, monitors) are powered off before making connections.
- Connect HDMI Sources: Connect your HDMI source devices to the HDMI IN 1-4 ports on the matrix switch using high-quality HDMI 2.0 cables.
- Connect HDMI Displays: Connect your HDMI display devices to the HDMI OUT A and HDMI OUT B ports on the matrix switch using high-quality HDMI 2.0 cables.
- Connect Audio System (Optional): If using external audio, connect your amplifier or soundbar to the SPDIF OUT, COAX OUT, or 3.5mm Audio OUT ports.
- Connect Power Adapter: Plug the included power adapter into the DC 5V port on the matrix switch, then plug the adapter into a power outlet.
- Power On Devices: Power on the matrix switch, then power on your display devices, and finally your source devices.
The matrix switch will automatically detect the input signals. You can then select the desired input for each output using the front panel buttons or the remote control.
7. Operating Instructions
Switching Inputs
- Using Front Panel Buttons:
- Press the "OUTPUT A" button to cycle through inputs for Display A.
- Press the "OUTPUT B" button to cycle through inputs for Display B.
- Using Remote Control:
- Press the corresponding IN1-IN4 button under "OUTPUT A" to select the input for Display A.
- Press the corresponding IN1-IN4 button under "OUTPUT B" to select the input for Display B.
Audio Return Channel (ARC)
The ARC function allows audio from your TV (connected to HDMI OUT A) to be sent back to the matrix switch and then output through the SPDIF, Coaxial, or 3.5mm audio ports. This is useful for playing TV's internal apps audio through your sound system.
- Ensure your TV supports ARC and that the ARC function is enabled in your TV's settings.
- Connect your TV to HDMI OUT A.
- Press the "ARC" button on the remote control to activate or deactivate the ARC function. The ARC LED indicator on the front panel will illuminate when active.
8. Audio Extraction
The matrix switch can extract audio from the selected HDMI input and output it through the dedicated audio ports (SPDIF, Coaxial, 3.5mm). This allows you to connect to external audio receivers, soundbars, or headphones.
- SPDIF/Coaxial Output: Supports Dolby Digital, DTS, and LPCM 2.0 audio formats.
- 3.5mm Audio Output: Provides analog stereo audio. This output will only carry LPCM 2.0 audio. If the source audio is multi-channel (e.g., Dolby Digital, DTS), ensure your source device or the matrix switch's EDID settings are configured to output LPCM 2.0 for this port.
9. EDID Management
EDID (Extended Display Identification Data) is crucial for ensuring compatibility between source devices and displays. The matrix switch offers EDID management to optimize video and audio performance.
The EDID settings can typically be adjusted via the EDID button on the front panel or remote control. Common EDID modes include:
- COPY EDID: The matrix copies the EDID from the connected display (usually Output A) to ensure maximum compatibility.
- FIXED EDID: The matrix uses a built-in EDID (e.g., 4K@60Hz, 1080p, 2.0CH audio) to ensure stable output regardless of the connected display's capabilities.
- MIXED EDID: The matrix attempts to find a common resolution and audio format supported by all connected displays.
Refer to the specific EDID indicators on the device (if available) or cycle through modes to find the best setting for your setup. If you encounter display issues, try adjusting the EDID mode.
10. Maintenance
