for data transmission.
I
2
S is a digital output utilizing the HDMI connector on the back of the NPC. The output of this
connector is NOT compatible with a standard HDMI connected unit of any kind. There are no
HDMI compatible signals here, do not try and plug this into an HDMI input. This output uses the
I
2
S interface protocol standard developed by PS Audio. Multiple manufacturers have adopted this
standard in their equipment and the standards are freely given to any audio manufacturer wishing
to follow them.
For most of you, the PS Audio PerfectWave series will be the main devices that can take advantage
of this output. The I
2
S output carries full PCM and DSD at all sample rates and bit depths just
described in the Coax section. I
2
S is the native protocol for digital audio used in all DACS, CD
players and transports. I
2
S is the NATIVE format used by these devices and it is this protocol that
is COMPRESSED to S/PDIF for transmission over Coax, XLR or Optical outputs on devices.
I
2
S contains separate clocks and data lines and does not have jitter related issues. Most jitter
problems arise from the use of the S/PDIF protocol because compressing the native I
2
S data
and clocks together into one stream and then unravelling this compressed format back to I
2
S
(as is required for it to work) is typically where jitter is introduced. I
2
S should be the transmission
medium of choice if you have a compatible receiver to accept it.
The USB output is intended to feed a computer, not the USB input on a DAC or similar device. Do
NOT attempt to plug the USB digital output of the NPC into the USB input of your DAC. Frustration
and silence will be your only reward for doing so. The USB output of the NPC connects the NPC
to your computer. The NPC will look like a peripheral device to your computer. The NPC is a
SLAVE and your computer is the MASTER in the same way you might connect up any USB source,
printer or peripheral.
The USB output of the NPC will work with both Windows and Mac PC’s. Windows will require you
