Centre Phase
As in the previous test, signals are applied to the main left, right,
and centre speakers to allow you to adjust the relative phase
and delay on the centre channel.
Use > and < to switch between phase and delay.
When setting phase the display shows the absolute phase of the
centre speaker.
For example:

Use A and V to change the phase.
Choose the correct setting as follows:

Correct The centre speaker reinforces the
sound.
Incorrect The sound from the centre cancels
some of the image formed by the left
and right speakers.
When setting the delay the display shows the relative
displacement, in feet, of the centre speaker.
Use A and V to adjust the delay.
