As you increase the delay the centre speaker will appear to move away from you. In practice we usually find that the ideal delay setting is +0.5 more than the value used to time-align the system.

This calibration test adjusts the relative phase between the front speakers and the rear surround speakers.

Surr R Phs +

After a short delay the display shows:

For example, if the original value was

+1.0' adjust it to:

Centre +1.5'

●Use A and V to change the phase of the right surround speaker.

This is equivalent to moving the centre speaker 1/2 foot further away from the listener.

You have now calibrated all the front speakers.

●Press Store to proceed to the next calibration test.

Choose the correct setting as follows:

Setting

What it sounds like

Correct

A focused central image between the

 

right front and rear speakers.

Incorrect

A diffuse, phasey image between the

 

two right speakers that changes as you

 

move your head.

This is a difficult setting to adjust, but is particularly important for the Ambisonic and Super Stereo DSP modes.

●Press Store to proceed to the next calibration test.
