I see that some interfaces have ADAT, but then they also have S/MUX and others say SMUX II (or SMUX 2) and other say SMUX IV or SMUX 4. What does all this mean?

Best answer
ADAT Optical is 8 channels of audio ranging from 16-bit 44.1KHz to 24-bit 48Khz in quality.

ADAT SMUX II allows 4 channels of audio at 24-bit 96KHz over the same optical cable. By sacrificing 4 channels of audio, the optical cable interface is able to handle a higher signal quality audio capture signal.

ADAT SMUX IV allows 2 channels of audio at 24-Bit 192KHz over the same optical cable. By sacrificing 6 channels of audio, the optical cable interface is able to handle a higher signal quality audio capture signal.
