4. Setup Instructions

Follow these steps to connect your AYINO HD950 to your audio and video system.

4.1 Connecting Input Sources

Figure 4.1: General interface connection diagram for various input and output devices.

• HDMI Inputs: Connect your source devices (e.g., TV box, game console, Blu-ray player) to HDMI1 or HDMI2 ports on the rear panel.
• HDMI ARC: If your TV supports Audio Return Channel (ARC), connect an HDMI 2.0 (19+1 core) cable from your TV's HDMI ARC port to the HDMI OUT(ARC) port on the HD950. This allows audio from your TV to be sent back to the decoder.
• Optical/Coaxial: Connect digital audio sources (e.g., TV, set-top box) to the OPTICAL or COAXIAL input ports.
• PC-USB: Connect your computer to the PC-USB port using the provided USB A to USB B cable to use the HD950 as an external sound card.
• USB Disk/SD Card: Insert a USB flash drive or SD card into the respective slots for media playback.
• Bluetooth: Attach the wireless antenna to the BT port. Enable Bluetooth on your mobile device and pair with 'HD950'.
• AUX: Connect analog audio sources to the AUX input.

4.2 Connecting Output Devices

• 5.1 Channel Analog Output: Connect the 5.1ch RCA outputs (FL, FR, CEN, SUB, SL, SR) to a 5.1 channel amplifier or active 5.1 speakers.
• 2.0 Channel Analog Output: Connect the FL and FR RCA outputs to a 2.0 channel amplifier or active 2.0 speakers.
• HDMI Output: Connect the HDMI OUT(ARC) port to your monitor, HDTV, or projector for video output.
• Digital Audio Output: Connect the COAXIAL or OPTICAL output ports to a digital amplifier or digital speakers for digital audio passthrough (not supported for U disk playback).

4.3 Power Connection

Connect the provided power adapter to the DC 12V/1A input port on the rear panel and then plug it into a power outlet.

6. Maintenance

• Cleaning: Use a soft, dry cloth to clean the device. Do not use liquid cleaners or aerosols.
• Environment: Keep the device in a cool, dry place, away from direct sunlight, heat sources, and moisture.
• Ventilation: Ensure adequate ventilation around the device to prevent overheating. Do not block ventilation openings.
• Power: Disconnect the power adapter if the device will not be used for an extended period.

7. Troubleshooting

If you encounter issues with your AYINO HD950, please refer to the following common problems and solutions:

• No Sound Output:
  • Ensure all audio cables (RCA, Optical, Coaxial) are securely connected.
  • Verify that the correct input source is selected on the HD950.
  • Check the volume level on both the HD950 and your connected amplifier/speakers.
  • Confirm that your source device is outputting audio in a supported format.
  • If using ARC, ensure your HDMI cable is HDMI 2.0 (19+1 core) and ARC is enabled on your TV.
• No Video Output (HDMI):
  • Ensure HDMI cables are securely connected between the source, HD950, and display.
  • Verify the correct HDMI input is selected on your display.
  • Check if the source device is powered on and outputting video.
• Incorrect Surround Sound:
  • Ensure your source material is 5.1 channel audio. If the source is 2.0 channel, the HD950 will decode it to virtual 5.1.
  • Verify that your amplifier/speakers are configured for 5.1 channel input.
  • Check the audio settings on your source device to ensure it's outputting the desired audio format (e.g., Bitstream for DTS/AC3).
• Remote Control Not Working:
  • Ensure batteries are correctly inserted and not depleted.
  • Point the remote directly at the infrared receiver on the front panel.
  • Remove any obstructions between the remote and the device.
