Si, il pc credo che comunque debba avere un'uscita digitale e l'usb venga usata solo per gestire i diffusori (leggi nei link che metterò più sotto). Credo che puoi collegare fino a 3, se non 4, sorgenti contemporaneamente scegliendo da telecomando quale ascoltare.
Preso dal manuale d'uso:
Selectable Inputs
In this age of digital workstations and control surfaces, it isn’t enough to simply provide an
input jack. The LSR4300 offers three separate inputs: stereo high-resolution 96 kHz AES/
EBU and S/PDIF digital inputs, as well as dual balanced analog XLR and ¼-inch inputs with
selectable +4dBu / -10dBV sensitivity. This allows it to accommodate a wide range of input
sources, including digital workstations, CD players, DVD players, and multi-channel processors.
What’s more, you can easily select between inputs with the push of a single button (on
either the front panel or the wireless remote) or click of a mouse (via an attached computer and
the included LSR4300 Control Center software).
