4) If the channels are reversed, check the wiring to the speakers and re-route if
necessary. If the wiring to the speakers is correct, check all other system wiring and fix
any incorrect channel routing.
5) Track 3 is a phase verification track to confirm that speaker to speaker phase is
correct. To use this track effectively, you should be centered between the speakers
and 3' - 5' away. The track alternates several times between the spoken phrase “In
phase” followed by pink noise played in phase, and “out of phase” followed by pink
noise played out of phase. Both the voice introduction and the pink noise will be
either in phase or out of phase.
6) When everything is set up correctly, you should hear:
a. In Phase - the voice and the pink noise will have a clearly defined point of
origin centered between the speakers.
b. Out of Phase - the voice and pink noise will have no clearly defined origin and
may even sound as if the sound originates outside of the speakers.
c. There will also be a distinct difference in bass levels with the pink noise. The
pink noise will sound fuller (more bass) when in phase, and thinner (less bass)
when out of phase.
7) If you hear the opposite effects, check the wiring polarity to each speaker and correct
any incorrect wiring (red to red, black to black, “+” to “+”, “-“ to “-“, “-“ to black, “+” to
red). In some cases, the equipment setup or environment can cause confusing results.
If the wiring seems correct, try moving your listening position towards the speakers
and move slightly to one side of center, listen, and then move slightly to the other side
of center and listen. If you still don’t hear what you think you ought to, try reversing
only the left DWT4416 input wire polarity and perform the phase test again.
