Configuration Display — This graphics box shows which speaker channels are
4
active (see figure 37 on the previous page). Only the speakers enabled are displayed.
If Full Range is selected for a particular channel then the speaker is represented by a
large icon. If Bass Management is selected for a particular channel then the speaker is
represented by a small icon.
Speaker Delay
These controls introduce a signal delay for each enabled speaker (see figure 38). The two
main reasons to adjust the signal delay are:
• To compensate for unequal distances between the speakers and the listener, which
causes sound from different speakers to reach the listener at different times.
To compensate for a lack of coordination between the audio and the accompanying
•
video signal.

Speaker Distance
When speakers are arranged in a room, there is a central location or "sweet spot" that
offers the best listening point. However, even in that central location, the speakers are not
necessarily all equidistant from the listener, and the sound from the closest speaker reaches
the listener before the sound from speakers that are further away.
Speaker distance settings delay the signals going to each individual speaker (from 0 to
700 ms) so that the signals from all the speakers are synchronized and reach the listener
simultaneously. The default setting for each speaker is 0 ms.
Speakers that are not available in the current configuration are not displayed. When the
back surround is set to one speaker, the right back speaker is unavailable and the left back
speaker is renamed as the center back.
