The USB port can also be used to connect a DC 5V power supply (not included)

standard stereo phono cables to output sound

Warning: Always start with the volume dial at the minimal
setting before connecting headphones. This will
help ensure you don't get unexpected high volume
levels that could damage your hearing
Installation
1. Power down the equipment that the DAC will be attached to
2. Connect the relevant input/output cables as described above
3. Set the Input switch to the desired selection
4. If the DAC is not connected to a computer connect it to a USB power supply (not included) that is
capable of providing 5V 500 – 1000mA
5. Power up the source device and begin audio playback
Please Note: The USB DAC 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.
