The digital inputs on our 2-channel DACs will accept any 2-channel PCM digital signal up to 24/192 resolution, available through coaxial, Toslink and/or USB Audio digital input connections. This allows for the connection of CD transports, music servers, squeezbox type devices and DVD players for the decoding of two channel PCM soundtracks.
If connecting to a DVD/BD player, smart TV or similar device you will need to make sure that the source is set to output two-channel PCM, rather than other signals such as bitstream, Dolby Digital, DTS or multi-channel, etc.
