Configuring the digital surround processor
28
The next stage in configuring the 565 is to specify information
about each of the speakers in your layout, and adjust their
delays to time-align the system so that sounds are coincident
when they arrive at the listening position.

To time-align the system

Before setting up the speaker outputs you need to measure the
distance, in cm or inches, to each speaker from the listening
position.
As you measure each distance, write it against the
appropriate line in the diagram opposite (or a copy of it).
Measure from the ear height at the listening position to the
tweeter on each speaker (where applicable).
Then decide which speaker is furthest from the listening
position; this distance is referred to as furthest below.
