Setup Instructions

1. Connect your HDMI source device (e.g., Blu-ray player, PS4) to the "HDMI IN" port of the Neoteck converter using an HDMI cable.
2. Connect your HDMI display (e.g., TV, projector) to the "HDMI OUT" port of the Neoteck converter using an HDMI cable.
3. For audio output:
   • To use optical audio, connect an optical cable from the "SPDIF" port of the converter to your audio receiver or soundbar.
   • To use analog stereo audio, connect RCA cables from the "R/L" ports of the converter to your stereo amplifier or speakers.
4. Connect the provided USB power cable to the "DC5V" port on the converter and then to a USB power source (e.g., a USB port on your TV, a USB wall adapter). The red Power LED will illuminate.
5. Ensure all connected devices (source, display, audio system) are powered on. The green HDMI LED will illuminate when a stable HDMI connection is established.

Operating Instructions

The Neoteck DAC04 features a switch on the front panel to select the desired audio output mode: PASS, 2.0CH, or 5.1CH.

• PASS Mode: In this mode, the SPDIF audio output format depends on the EDID (Extended Display Identification Data) of the connected TV or display. The audio signal is passed through without modification.
• 2.0CH Mode: When set to "2.0CH", the SPDIF output audio format will be LPCM 2-channel stereo. This is suitable for stereo audio systems.
• 5.1CH Mode: When set to "5.1CH", the SPDIF output audio format will be 5.1-channel. For this mode to function correctly, the source audio must also be 5.1CH. This mode supports Dolby Digital and DTS 5.1-channel audio.

Troubleshooting

• No Video Output:
  • Ensure all HDMI cables are securely connected.
  • Verify that the HDMI source device and display are powered on and functioning correctly.
  • Check if the converter's red Power LED is illuminated. If not, ensure the USB power cable is connected to a working power source.
  • Confirm that your display supports the input resolution (up to 4K@30Hz). This converter does not support 4K@60Hz.
• No Audio Output:
  • Check all audio cables (SPDIF, RCA) for secure connections.
  • Ensure your audio receiver/amplifier is powered on and set to the correct input.
  • Verify the audio mode switch on the converter is set appropriately (PASS, 2.0CH, or 5.1CH) for your audio system and source content.
  • If using 5.1CH mode, confirm that the source audio is indeed 5.1CH.
  • Note that Dolby Digital Plus is not supported by the SPDIF output.
  • If using PASS mode, the SPDIF output format depends on the TV's EDID. Try 2.0CH or 5.1CH mode if you experience issues.
• Poor Audio Quality:
  • Ensure all cables are high quality and not damaged.
  • Check for interference from other electronic devices.
  • Adjust audio settings on your source device and audio receiver.
