Operating Manual
The stereo digital outputs of the PST can be transferred through three types of connections.
I
2
S Sources
PS Audio’s recommended connection to DACs is through its
I
2
S
protocol.
I
2
S
delivers the best
sonic experience by separately transmitting data and clocks over an HDMI cable. A growing
number of high-end audio DACs have adopted PS Audio’s
I
2
S
standard, which we freely offer
and support to the high-end audio manufacturing community. The PST is compatible with all
properly implemented DACs that are compatible with our published protocols.
Although an HDMI cable is used for the I
2
S connections it’s important to note that I
2
S data is not
HDMI data, and the PST’s I
2
S output should not be connected to the HDMI input on a DAC or
receiver. The HDMI connector and cabling are used only to deliver audio via I
2
S.
Connect a high-quality HDMI cable between the PST’s I2S output to a compatible DAC’s I
2
S (via
HDMI) input. Note: the quality and length of the HDMI cable have significant impacts on audio
performance. The shorter the cable, the better the sound. We recommend using a ½-meter
