1. Introduction
This manual provides detailed instructions for the installation and operation of your ROFAVEZCO 4K60Hz 4x2 HDMI Matrix with Audio Extractor. This device is designed to distribute four HDMI input sources to two HDMI displays, supporting advanced video and audio formats.
The HDMI Matrix supports HDMI 2.0 specifications, including 4K@60Hz with 4:4:4 chroma subsampling, 18Gbps bandwidth, 8-bit HDR, Dolby Vision, HDR10, and Hybrid Log-Gamma (HLG). It also supports 1080p at 120Hz/60Hz 3D, 3840x2160 at 60Hz, and 1440p at 60Hz resolutions. Audio support includes Dolby Atmos Digital 7.1CH and DTS:X audio.
An integrated audio extractor (EX11PRO) allows for de-embedding SPDIF Optical Digital (5.1CH) and 3.5mm L/R Stereo Audio (2.1CH) for connection to external audio systems, such as soundbars or amplifiers, especially useful for displays or projectors without dedicated audio output ports.

4. Setup and Connection
Follow these steps to connect your devices to the HDMI Matrix and Audio Extractor:
- Power Off All Devices: Before making any connections, ensure all source devices, displays, and the HDMI Matrix are powered off.
- Connect HDMI Sources: Connect your HDMI source devices (e.g., PS5, Xbox, Blu-ray player, Apple TV) to the HDMI IN 1-4 ports on the HDMI Matrix using high-quality HDMI 2.0 cables (recommended length 3-5 meters).
- Connect HDMI Displays: Connect your HDMI displays (e.g., TV, projector) to the HDMI OUT A and HDMI OUT B ports on the HDMI Matrix.
- Connect Audio Extractor (Optional):
- If using the audio extractor, connect the HDMI OUT from the matrix to the HDMI IN on the EX11PRO.
- Connect the HDMI OUT from the EX11PRO to your display.
- Connect your audio receiver or soundbar to the SPDIF Optical Digital output (for 5.1CH audio) or the 3.5mm L/R Stereo Audio output (for 2.1CH audio) on the EX11PRO.
- Connect Power: Connect the provided power adapter to the DC 5V port on the HDMI Matrix and then plug it into a power outlet.
- Power On Devices: Power on your displays first, then your audio receiver (if applicable), and finally your HDMI source devices.

5. Operation
The HDMI Matrix allows you to switch between four input sources and route them to two independent outputs. The integrated DIP switches provide advanced configuration options for HDCP, scaling, and EDID management.
5.1 Input/Output Selection
Use the front panel buttons (IN1-IN4 for each output) or the IR remote control to select the desired input source for each output (Output A and Output B). Both outputs can display the same source or different sources simultaneously.
5.2 DIP Switch Configuration
The DIP switches on the HDMI Matrix allow for fine-tuning of video and audio settings. Refer to the diagram below for specific configurations. Always power cycle the device after changing DIP switch settings for changes to take effect.

Figure 5: Detailed DIP switch settings for HDCP compatibility (Position 1), scaler settings (Position 2), and EDID configuration (Positions 3-5).
5.2.1 HDCP Setting (DIP Switch 1)
- OFF: Normal HDCP mode.
- ON: HDCP test mode. Use only if experiencing HDCP compatibility issues with specific devices.
5.2.2 Scaler Setting (DIP Switch 2)
This switch controls the down-scaling for HDMI OUT A. Output B can be configured similarly if the matrix supports independent scaling per output (check specific model documentation).
- OFF: Pass-through (no scaling).
- ON: HDMI OUT A 4K to 1080P down-scaling. Useful for connecting a 4K source to a 1080P display while maintaining 4K on another output.
5.2.3 EDID Setting (DIP Switches 3, 4, 5)
EDID (Extended Display Identification Data) settings inform the source device about the display's capabilities. Incorrect EDID can lead to resolution or audio issues. The matrix allows you to manually set EDID or copy it from an output.

Figure 6: Table detailing various EDID configurations and scaler settings based on DIP switch positions.
Common EDID configurations include:
- Copy EDID: Copies the EDID from HDMI OUT 1 (or a specified output) to ensure compatibility with the connected display.
- 1080P_3D_2CH_HDR: Forces 1080P resolution with 3D and 2-channel audio, supporting HDR.
- 4K60Hz_4:2:0_2CH_HDR: Forces 4K@60Hz with 4:2:0 chroma, 2-channel audio, and HDR.
- 4K60Hz_4:2:0_8CH_HDR: Forces 4K@60Hz with 4:2:0 chroma, 8-channel audio, and HDR.
- 4K60Hz_4:4:4_2CH_HDR: Forces 4K@60Hz with 4:4:4 chroma, 2-channel audio, and HDR.
- 4K60Hz_4:4:4_8CH_HDR: Forces 4K@60Hz with 4:4:4 chroma, 8-channel audio, and HDR.
- 4K_Dolby Vision_Dolby Atmos: Optimized for Dolby Vision and Dolby Atmos audio.
- For PS5 (DIP 3,4,5 ON): Specific setting for PlayStation 5 compatibility.
For detailed EDID settings, refer to the provided table and experiment to find the best setting for your specific setup. For PS5, setting DIP switches 3, 4, and 5 to ON is recommended.

5.3 Audio Extractor Operation (EX11PRO)
The EX11PRO audio extractor provides flexible audio output options:
- SPDIF Optical Digital (5.1CH): Connect to a 5.1 channel audio system for surround sound. To ensure 5.1CH output, connect your 5.1ch audio system first.
- 3.5mm L/R Stereo Audio (2.1CH): Connect to stereo speakers or headphones.
Important Audio Note:
- The 3.5mm Stereo Audio output has higher priority than the SPDIF 5.1CH output.
- SPDIF and 3.5mm audio outputs do not work simultaneously. When SPDIF 5.1CH is active, the 3.5mm 2.1CH output is off.
- The HDMI port's Dolby Atmos audio and SPDIF 5.1ch audio alternate; they do not work in sync.
6. Troubleshooting
If you encounter issues with your HDMI Matrix or Audio Extractor, refer to the following common solutions:
- No Video/Audio Output:
- Ensure all HDMI cables are securely connected and are HDMI 2.0 compliant.
- Verify the power adapter is correctly connected and the device is powered on.
- Try a different HDMI input or output port.
- Check the selected input source on the matrix and your display.
- Power cycle all connected devices (source, matrix, display, audio receiver).
- Incorrect Resolution or Picture Quality:
- Adjust the EDID DIP switch settings (DIP 3-5) on the matrix to match your display's capabilities or force a specific resolution.
- If connecting a 4K source to a 1080P display, ensure the scaler DIP switch (DIP 2) is set to ON for 4K to 1080P down-scaling.
- Ensure HDMI cables are of sufficient quality and length (3-5 meters recommended for 4K@60Hz).
- No 5.1CH Audio from SPDIF:
- Ensure your audio receiver/soundbar is connected to the SPDIF output and is configured for 5.1CH input.
- Verify that the source device is outputting a 5.1CH audio signal.
- Remember that SPDIF and 3.5mm audio do not work in sync; ensure 3.5mm is not active if you need SPDIF 5.1CH.
- For PS5, ensure DIP switches 3, 4, and 5 are set to ON.
- HDCP Issues:
- If you encounter HDCP errors, try setting DIP switch 1 to the "ON" (test mode) position. If the issue persists, ensure all devices in the chain support HDCP 2.2.
- Remote Control Not Working:
- Check the battery in the remote control.
- Ensure the IR receiver cable is properly connected to the matrix and positioned to receive signals from the remote.
- Ensure there are no obstructions between the remote and the IR receiver.
