Neoteck 192kHz Digital to Analog Audio Converter

1. 서론

The Neoteck 192kHz Digital to Analog Audio Converter is designed to convert optical Toslink or coaxial digital audio signals into analog L/R RCA and 3.5mm audio outputs. This device supports various mainstream audio formats, including DTS, Dolby AC3, LPCM, PCM, and RAW. It can convert Dolby/DTS 5.1CH digital audio into 2.0CH analog audio without requiring specific audio output format settings on your source device, unlike many other DACs. This converter is ideal for connecting modern digital audio sources like HDTVs, Blu-ray DVD players, PS3/PS4, and network players to analog audio systems, headphones, or speakers.

5. 설정 및 설치

Neoteck DAC 컨버터를 연결하려면 다음 단계를 따르십시오.

1. 전원 연결: Connect the provided USB power cable to the DC 5V Micro-USB port on the converter. Plug the USB-A end into a 5V USB power adapter (not included) or a USB port on your TV/device. The red Power LED will illuminate.
2. Connect Digital Audio Input: Choose either the Optical-In or Coaxial-In port on the converter. Connect your digital audio source (e.g., TV, game console, Blu-ray player) to the corresponding input port using an optical Toslink cable or a coaxial cable.
3. 아날로그 오디오 출력 연결:
   • For RCA output: Connect your analog amplifier or active speakers to the L-Out (white) and R-Out (red) RCA ports on the converter using RCA cables.
   • For 3.5mm headphone output: Plug your headphones into the 3.5mm 'Out' jack on the front panel.
4. 소스 장치 오디오 출력 구성: Ensure your source device (e.g., TV, game console) is set to output audio via its optical or coaxial port. For optimal performance with Dolby/DTS 5.1CH signals, the converter will automatically downmix to 2.0CH analog audio. You do not need to set your device to PCM output.

6. 사용 설명서

Once all connections are made and your source device is playing audio, the converter will automatically process the digital signal. Use the volume knob on the front of the converter to adjust the output volume for both the 3.5mm headphone jack and the RCA outputs simultaneously.

7. 문제 해결

• 사운드 출력 없음:
  • Ensure the converter is powered on (red Power LED is lit).
  • Verify all cables (power, input, output) are securely connected.
  • Check the volume level on the converter and your connected audio device (amp앰프/헤드폰).
  • Confirm your source device's audio output is set to Optical or Coaxial.
  • For some TVs (e.g., Samsung, LG), you may need to navigate to audio settings and select 'External Speakers' or 'Single Sound Out' and choose 'Optical'.
• 소리가 왜곡되거나 끊기는 현상:
  • Ensure the optical or coaxial cable is not damaged or bent excessively.
  • Try a different optical or coaxial cable.
  • 다른 전자 장치의 간섭을 확인하십시오.
• No 5.1 Surround Sound:
  • This converter is designed to convert 5.1CH digital audio (Dolby/DTS) into 2.0CH analog stereo output. It does not pass through or output discrete 5.1 channels in analog form.
• Bright Power LED:
  • The power LED is intentionally bright. If it is distracting, consider placing the unit in a less visible location or using a small piece of electrical tape to cover the light.
