Questions
- Can I connect this to an HDMI source directly?
- No. This decoder accepts only optical (Toslink) and coaxial digital audio inputs. For HDMI sources, use an HDMI audio extractor like the KanexPro AUD-DCODEHDMI-4K or AUD-DEBEDEARC-4K first.
- Does this require any driver or software installation?
- No. The decoder is fully plug-and-play. Connect cables, apply power, select the input, and audio output begins automatically.
- I hear static or distorted audio — how do I fix it?
- The source is likely outputting a format the decoder cannot handle (e.g., Dolby Digital Plus or DTS-HD). Change the source audio output to standard Dolby Digital or PCM. Also ensure the optical cable is fully seated.
- Does this decode Dolby Digital Plus or Dolby Atmos?
- No. The AUD-DCODE-ANA decodes standard Dolby Digital (AC-3) and DTS. It does not support Dolby Digital Plus (DD+), Dolby Atmos, or DTS-HD. For streaming services that default to DD+, set the source audio output to PCM or Stereo.
- What PCM sample rates are supported?
- The decoder supports PCM at 32kHz, 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, and 192kHz.
- Can I use both RCA and headphone outputs simultaneously?
- Yes. Both outputs are always active.
- What power supply is required?
- The unit requires a 5V/1A DC power adapter, which is included in the box. Do not use adapters with higher voltage as this may damage the unit.
- No sound from my speakers after connecting — what should I check?
- Verify the input selector switch matches your cable type. Check that the source device audio output is set to PCM, Bitstream, or Auto. Confirm the 5V power adapter is connected and the LED is active. If using a TV, set audio output to External Speakers.
- How does this differ from AUD2ACV?
- AUD2ACV is PCM-only. AUD-DCODE-ANA has licensed Dolby/DTS decoder DSP plus 3.5mm output.
- Why not a cheap DAC?
- Most basic DACs convert PCM stereo only and cannot decode Dolby or DTS bitstreams. This unit has licensed Dolby and DTS decoding.
