Phase checking
The first procedure you should carry out is checking
signal phase.
A number of signals both for two-channel stereo and
for multichannel reproduction are part of the Dynaudio
Professional AIR test tone sets.
Phase checking – two-channel Stereo:
Use tracks 45 to 49 for Stereo phase checking. Left and
right signals are presented in phase and subsequently
out of phase.
Phase checking – Multichannel:
Use tracks 45 to 64 for multichannel phase checking.
These are DTS-encoded signals that can be compared
pairwise: Left/Right, Left/Center, Left/Left Surround,
Right/Right Surround.
If you do not have a DTS decoder, you may route the
stereo L/R signals to other channels using your mixing
console.
If you already have a phase checking measurement
system that can be used as well.
Checking by ear when listening to the signals
In phase:
You will hear more bass and the sound will appear to
come from a fixed point between the monitors.
Out of phase:
You will hear the sound image lose bass, the sound
image will be diffuse, and the directional information will
be blurred.
