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.
