NuWave Phono Converter
NuWave-Phono-Converter-Owners-Manual.pdfPS Audio’s NuWave Phono Converter, NPC, is a new category for the High End that combines a state-of-the-art phono preamplifier and analog DSD/PCM converter together in a world’s first. This is high resolution audio at its best.
I2S 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
I2S 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 I2S output carries full PCM and DSD at all sample rates and bit depths just
described in the Coax section. I2S is the native protocol for digital audio used in all DACS, CD
players and transports. I2S 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.
I2S 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 I2S data
and clocks together into one stream and then unravelling this compressed format back to I2S
(as is required for it to work) is typically where jitter is introduced. I2S should be the transmission
medium of choice if you have a compatible receiver to accept it.
