5. Pokyny k nastavení
Follow these steps to connect your HDMI Audio Extractor:
- Připojení zdroje HDMI: Connect an HDMI cable from your source device (e.g., Blu-ray player, game console, streaming device) to the HDMI-IN port na extraktoru.
- Připojení HDMI displeje: Připojte kabel HDMI z HDMI OUT port on the extractor to your display device (e.g., TV, projector).
- Připojte zvukový výstup:
- For digital audio, connect a Toslink optical cable from the SPDIF port on the extractor to your audio receiver or soundbar.
- Pro analogový stereo zvuk připojte kabely RCA L/R z L/R Audio Output ports on the extractor to your stereo receiver or ampživější.
- Připojte napájení: Zapojte dodaný 5V napájecí adaptér do DC 5V input port on the extractor, then plug the adapter into a power outlet. The PWR indicator light will illuminate.
- Vyberte režim zvuku: Adjust the Audio EDID switch on the extractor according to your audio setup (see Section 6 for details).

6. Operating Instructions and Audio Settings
The HDMI Audio Extractor operates automatically once connected. The primary control is the Audio EDID switch, which determines how the audio signal is processed.
Audio EDID Settings:
- 2CH: Select this setting for L/R RCA stereo output or SPDIF stereo output. This mode ensures that the audio signal is downmixed to 2-channel PCM stereo, compatible with most stereo audio receivers and the analog RCA outputs.
- 5.1CH: Use this setting for optical audio output to a surround-sound receiver. This mode allows the SPDIF output to carry Dolby Digital or DTS 5.1CH audio signals. Ensure your audio receiver supports these formats. The RCA L/R outputs will not produce sound in this mode unless the source also outputs 2CH PCM simultaneously.
- PŘIHRÁVKA: In this mode, the audio EDID information from the connected HDMI display (TV) is passed through to the HDMI source. The audio output capabilities will be determined by your display. This setting is typically used when you want the HDMI TV speakers to handle the sound, or when your display has specific audio processing capabilities you wish to utilize.
Poznámka: The ability to extract HDMI audio without an active output connection is source-dependent. Some HDMI sources may require an active HDMI output connection to function correctly.
7. Řešení problémů
- Žádný video výstup:
- Ujistěte se, že jsou všechny kabely HDMI bezpečně připojeny.
- Verify the power adapter is connected and the PWR indicator is lit.
- Try connecting the HDMI source directly to the display to confirm the source and display are working.
- If using a DVI-type display, ensure the HDMI source allows selection of RGB color to avoid compatibility issues. For HDMI to DVI applications, consider models like VHD-UHAE.
- Žádný audio výstup:
- Check all audio cable connections (Toslink or RCA).
- Verify the Audio EDID switch setting:
- For RCA L/R or SPDIF stereo, set to 2CH.
- For SPDIF 5.1CH surround sound, set to 5.1CH. Ensure your receiver supports Dolby Digital/DTS.
- If using TV speakers, set to PŘIHRÁVKA.
- Ensure your audio receiver/soundbar is set to the correct input source.
- Confirm the HDMI source is outputting audio.
- Intermittent Audio/Video:
- Zkontrolujte, zda nejsou uvolněné kabelové spoje.
- Try using different HDMI cables.
- Ujistěte se, že je napájecí zdroj stabilní.
