DP-750 has 4 digital inputs, Coaxial, Optical, HS-LINK and

USB.

USB Input accepts 384kHz/32bit-PCM or 11.2896MHz-DSD.

DSD data can be received both DoP（DSD over

PCM）and ASIO2.1 (11.2896MHz: ASIO only).

HS-LINK has been evolved into Version2.

Original HS-LINK(Ver.1) transmits and receives only

192kHz/24bit-PCM or 2.8224MHz-DSD, but Ver.2 comes

to be able to transmit and receive 384kHz/32bit-PCM,

5.6648MHz-DSD.

DP-750 automatically recognizes either Ver.1 or Ver.2

transmissions.
