1.1 Сүрөттөмө
The J-Tech Digital JTDAUDIOSW4x1 is a versatile audio converter and switch designed to integrate various digital audio sources with analog audio systems. This device features four audio inputs: two optical audio (TOSLINK) and two coaxial audio inputs. It provides multiple outputs including one optical audio (TOSLINK) output, one analog stereo RCA L/R audio output, and one 3.5mm headphone output.
The unit supports conversion from coaxial audio to TOSLINK audio. The RCA L/R and 3.5mm analog audio outputs are capable of handling incoming digital stereo audio formats up to 192KHz. It is important to note that this device functions as an audio converter and switch, not an audio decoder. It cannot decode and convert multi-channel surround sound formats (such as Dolby Digital 5.1CH/AC3) to stereo. For such functionality, a dedicated audio decoder would be required.
1.2 Негизги өзгөчөлүктөрү
- Input Versatility: Equipped with 4 SPDIF audio inputs, including two TOSLINK and two Coaxial ports.
- Бир нече чыгуулар: Offers 3 distinct outputs: one Optical/TOSLINK, one L/R Stereo, and one 3.5mm Headphone jack.
- Audio Format колдоо: Supports digital audio formats such as Dolby Digital (AC3), DTS, HDCD, and LPCM for SPDIF output. It also supports LPCM digital audio for analog audio output.
- Камтылган DAC: Features a built-in Digital-to-Analog Converter (DAC) that supports stereo audio formats up to 192KHz. For analog audio output, the incoming SPDIF audio must be in Mono or Stereo format.
- Coaxial to TOSLINK Conversion: Capable of converting coaxial audio signals to TOSLINK audio.
- Automatic Signal Identification: Automatically identifies the input digital audio signal format. Analog output will mute if a non-LPCM input is detected.
- Туруктуу курулуш: Housed in a reliable metal case for enhanced durability.
- Интуитивдик башкаруу: Features a dual-functional button for both Power On/Off and Input Switching.

| Көйгөй | Мүмкүн себеп | Чечим |
|---|---|---|
| Аудио чыгышы жок | Incorrect input selected; Loose cable connections; Device not powered on; Source device not outputting audio; Analog output muted due to non-LPCM input. | Ensure the correct input is selected on the JTDAUDIOSW4x1. Check all cable connections (optical, coaxial, RCA, 3.5mm) are secure. Verify the device is powered on. Confirm your source device is outputting audio. Ensure the digital audio input is LPCM for analog outputs. |
| Аудио сапаты начар | Damaged cables; Incorrect audio format from source; Interference. | Replace cables if damaged. Ensure the source audio format is compatible. Keep the device away from other electronic equipment that may cause interference. |
| Түзмөк жооп бербей жатат | Power issue; Device malfunction. | Check power adapter connection and wall outlet. Try unplugging and re-plugging the power adapter. If the issue persists, contact customer support. |
| Analog output (RCA/3.5mm) not working, but Optical output is fine | Input audio format is not LPCM (e.g., Dolby Digital, DTS). | The analog outputs only support LPCM stereo audio. Ensure your source device is set to output LPCM (PCM) stereo audio. This device does not decode multi-channel formats to stereo. |
