The UT23 connects to your computer via USB and sends out an optical SPDIF signal. There is no DAC involved, just the USB to optical feature.
It works in USB Audio Class 1 (sample rates up to 96kHz/24bit) and works without drivers with all major systems and programs; Windows, MAC, Linux. It appears as an audio device with stereo outputs and can send optical audio from any program from your computer.
The output is optical 3.5mm connector. We include a cable TOSLINK to 3.5mm and also a TOSLINK to 3.5mm adaptor, so that you can use both if your source has the bigger TOSLINK optical connector, or a 3.5mm optical output.
The output also supports sending Dolby audio 5.1, AC3 streams.
