3. Setup Instructions

Follow these steps to properly set up your AV Access 4KEX70-ARC-H2 HDMI Extender:

1. Prepare Your Equipment: Ensure your TV and AV Receiver (AVR) support ARC functionality. Use certified HDMI 2.0 or higher cables for optimal performance with 4K UHD images. For the extension, use a Cat6a/7 Ethernet cable with sufficient capacity for your desired transmission distance and resolution.
2. Connect the Transmitter to your AVR: Use an HDMI 2.0 cable to connect the HDMI Out (ARC) port of your AV Receiver to the HDMI In port on the HDMI Extender Transmitter. Ensure all your media sources (e.g., Blu-ray player, streaming device) are connected to your AVR.
3. Connect Transmitter and Receiver via CAT Cable: Connect the HDBT Out port on the Transmitter to the HDBT In port on the Receiver using a single Cat6a/7 Ethernet cable.
4. Connect the Receiver to the TV: Use an HDMI 2.0 cable to connect the HDMI Out port on the HDMI Extender Receiver to the HDMI ARC port on your TV.
5. Power the HDMI Extender: Connect the provided power adapter to either the Transmitter or the Receiver. This model supports bi-directional Power over Cable (PoC), meaning only one unit needs to be powered, and it will supply power to the other unit via the Cat cable.
6. Connect IR Cables (Optional): If you wish to control source devices from the TV end or the TV from the source end, connect the IR Receiver cable to the IR In port on the Receiver and the IR Emitter cable to the IR Out port on the Transmitter. Position the IR emitter head near the IR sensor of the device you want to control. If controlling the other way around, swap the IR cables (IR Receiver to Transmitter, IR Emitter to Receiver).
7. Set Audio Control Mode: On the Receiver unit, use the DIP switch for "Audio Control" to select either "ARC" or "S/PDIF In" mode based on your audio routing needs. For TV audio return, select "ARC".

4. Operating Instructions

Once the setup is complete, you can begin using your HDMI extender. Ensure your TV's ARC function is enabled in its settings.

• ARC Audio Return: When the Audio Control DIP switch is set to "ARC", audio from your TV's built-in apps or connected devices will be sent back to your AV Receiver through the extender, allowing you to enjoy 5.1 surround sound through your home theater system.
• S/PDIF Audio Input: If you encounter ARC incompatibility issues or prefer an external audio source, switch the Audio Control DIP switch to "S/PDIF In". This allows you to transmit audio via an S/PDIF cable from an external source to your AVR.
• IR Control: Use your existing remote controls to operate devices connected to either the Transmitter or Receiver end. The bi-directional IR feature allows seamless control across the extended distance.
• HDMI CEC: The extender supports HDMI CEC, enabling you to use your TV remote to select and control source devices connected to your AVR, simplifying your home theater experience.

5. Maintenance

To ensure the longevity and optimal performance of your HDMI extender, follow these maintenance guidelines:

• Cleaning: Use a soft, dry cloth to clean the exterior of the units. Avoid using liquid or aerosol cleaners, as they may damage the device.
• Ventilation: Ensure the units have adequate ventilation to prevent overheating. Do not block any ventilation openings.
• Cable Management: Keep all cables neatly organized and avoid sharp bends or excessive tension, which can damage the cables or ports.
• Storage: When not in use for extended periods, store the extender in a cool, dry place away from direct sunlight and extreme temperatures.

6. Troubleshooting

If you encounter issues with your HDMI extender, refer to the following common troubleshooting steps:

• No Video/Audio:
  • Check all HDMI and Cat cable connections to ensure they are secure.
  • Verify that the power adapter is correctly connected and the power LED indicators on both units are lit.
  • Ensure your TV and AVR are set to the correct input sources.
  • Confirm that the Audio Control DIP switch on the Receiver is set to the appropriate mode (ARC or S/PDIF In).
  • Test with different HDMI and Cat cables to rule out cable issues.
• Poor Video Quality (Flickering, Distortion):
  • Ensure you are using certified HDMI 2.0 or higher cables.
  • Verify the Cat cable quality and length are within the recommended specifications for your resolution (refer to Section 7: Specifications).
  • Reduce the cable length if possible, especially for 4K@60Hz signals.
• IR Control Not Working:
  • Check that the IR Emitter and Receiver cables are correctly plugged into the respective ports and positioned correctly near the IR sensors of the devices.
  • Ensure there are no obstructions between the IR emitter/receiver and the device's sensor.
  • Try swapping the IR cables between the Transmitter and Receiver if you need to control devices in the opposite direction.
• ARC Audio Issues:
  • Ensure ARC is enabled in your TV's audio settings.
  • Verify that your AVR's input is correctly configured for ARC.
  • If issues persist, try using the S/PDIF In mode as an alternative audio return method.

If these steps do not resolve the issue, please contact AV Access customer support for further assistance.
