5. Installasjonsinstruksjoner

5.1. RCA to HDMI Converter Setup

1. Connect the male RCA (red, white, yellow) cables from the converter to the RCA output ports of your source device (e.g., DVD player, VCR). Ensure color matching.
2. Connect the HDMI output of the converter to an available HDMI input port on your HDTV or monitor.
3. Connect the integrated USB power cable to a 5V/1A USB power source (e.g., TV USB port, USB wall adapter). This is crucial for stable operation.
4. Power on your source device and HDTV. Select the correct HDMI input on your HDTV.
5. Use the 4:3/16:9 toggle switch on the converter to adjust the aspect ratio as desired.

5.2. Optical to RCA DAC Converter Setup

1. Connect the optical (Toslink) cable from your digital audio source (e.g., HDTV, Blu-ray player, game console, set-top box) to the optical input port of the DAC converter.
2. Connect RCA audio cables (red for right, white for left) from the RCA output ports of the DAC converter to the analog RCA input ports of your stereo amplifier eller aktive høyttalere.
3. Connect the provided USB power cable to the DAC converter and then to a 5V/1A USB power source.
4. Slå på alle tilkoblede enheter.
5. Viktig: Ensure your digital audio source's audio output format is set to PCM. This converter does not support Dolby AC3, DTS, or other 5.1 channel signals. Refer to section 6.2 for detailed instructions on setting PCM output.

6. Bruksanvisning

6.1. RCA to HDMI Converter Operation

Once connected and powered, the converter will automatically scale the analog RCA signal to 1080P or 720P HDMI output. The primary operational control is the aspect ratio switch.

• Aspect Ratio Switch (4:3 / 16:9): Use the physical toggle switch on the converter to select the desired display aspect ratio. This helps restore the original output ratio of older DVD/VCR players.

6.2. Optical to RCA DAC Converter Operation

The DAC converter operates automatically once connected and powered, converting the digital optical signal to analog RCA. The critical step for proper operation is configuring the audio source.

• Setting Audio Output to PCM: The converter is designed for PCM (Pulse Code Modulation) stereo audio. If your source device outputs Dolby AC3, DTS, or other multi-channel formats, you will not get sound. You must change the audio output setting on your source device (e.g., TV, Blu-ray player) to PCM.

General steps to set PCM output (may vary by device):

1. Go to your device's (e.g., TV, Blu-ray player) Innstillinger meny.
2. Naviger til Lyd or Lydinnstillinger.
3. Se etter Ekspertinnstillinger or Avanserte lydinnstillinger.
4. Finne Format for digital lydutgang or Lydformat.
5. Velge PCM (or Stereo) from the available options.

7. Feilsøking

• No Picture (RCA to HDMI):
  • Ensure the converter is properly powered via the USB cable. Try a different USB power source or a dedicated 5V/1A USB wall adapter.
  • Verify all RCA and HDMI cables are securely connected.
  • Check that your HDTV is set to the correct HDMI input.
  • The converter cannot improve the clarity of the original signal source. If the source signal is poor, the HDMI output will also be poor.
• Image Flickering or Noise (RCA to HDMI):
  • Ensure the USB power cable is connected to a stable 5V/1A power source. Insufficient power can cause signal instability.
  • Check if the RCA cable connections are fully seated.
• No Sound (Optical to RCA DAC):
  • Verify the DAC converter is powered.
  • Ensure the optical cable is securely connected and not damaged.
  • Crucially, check that your digital audio source's output format is set to PCM. This converter does not support Dolby AC3, DTS, or other 5.1 channel formats. Refer to section 6.2.
  • Sjekk volumnivået på din amplifier/speakers. The volume level can only be adjusted on the output device.
• Poor Audio Quality (Optical to RCA DAC):
  • Ensure all cables are connected firmly.
  • Test med en annen optisk kabel hvis mulig.
  • Verify the source audio quality.
