JAMO WK 200 Manual Del Usuario página 10

When the WK 200 senses a digital input signal (i.e.
from a TV or computer) it will automatically choose
to transmit the signal in digital form. This will allow
the best possible transfer of sound with the lowest
possible distortion and noise. If you choose digital
transmission both the transmitter and the receiver
will have to be connected by optical cables.
Optical input can only transmit PCM signal.
