Please Note:
The LDAC-Pro is not compatible with Dolby Digital or DTS formats, which are both forms
of compressed audio. If you play back CDs, DVDs or BDs encoded in Dolby Digital or DTS, you will only
hear some unwanted noise that may damage your speakers.
To work around this you need to access the menu setting of the source device and adjust Dolby Digital
or DTS to PCM. This USB DAC works with any PCM stream from CD players, DVD players and set-top
boxes.
