Optical input support 16 / 24-Bit ， 44.1kHz, 48kHz, 88.2kHz, 96kHz
USB conversion to I2S output support 16 / 24 / 32-Bit ,44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, 192kHz , 352kHz , 384kHz , DSD64 , DSD128
Two model coaxial outputs * :
             BNC (Applied Current Conveyor Technology,support up to 16 / 24-Bit ， 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, 192kHz)*
             RCA (Transformer  Transmit insulate ,support up to 16 / 24-Bit ， 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, 192kHz with most DACs )


*     The Current conveyor output can cooperate with most standard design DACs in world but some DACs can't cooperate . The transmit insulate model output can cooperate with all standard design DACs.
