After briefly displaying Wait, the following sequence occurs:
Normal
In-phase noise appears on both channels for several seconds.
None
Both outputs are muted for a second.
Inverted
A second burst of noise appears on both channels with the right channel
inverted for several seconds.
Done
This is displayed briefly at the end of the test.
If both channels are in-phase the first burst of noise will produce a stable central
image but the second burst will not. If one channel is out of phase, the second
burst will produce a stable stereo image but the first will not.
If there is a phasing error, check for wiring errors from the unit output onwards.
You cannot correct this error on a dCS DAC using the Phase feature as this
inverts both channels.

The ear responds to positive pressure substantially more than it does to negative pressure for low
frequencies, so it is worth getting the phasing correct.
