Nº40 Media Console Menu System
ASA back separation
If you have two back speakers, the Nº40 needs to get an indication
of how far apart they are in order to implement the Advanced
Speaker Array technology of THX Ultra2 Cinema and THX Music
Mode. You will be given the following options:
• Together: Separation is less than 1 foot (<0.3m)
• Intermediate: Separation is between 1 and 4 feet (>0.3–1.2m)
• Apart: Separation is greater than 4 feet (>1.2m).
THX recommends that they be placed together facing forward for
best ASA effect.
Listener position
One of the big advantages of high quality multichannel systems is
that the “sweet spot” in which a film can be enjoyed is expanded as
compared to simple two-channel stereo. However, there are limits.
In particular, if you want the best possible performance in two or
three different locations in the room, the distances from the
speakers and their perceived output levels can vary significantly.
You may have a “best seat in the house” location in the middle of
the room, where the speakers are placed symmetrically about you.
You may, however, also want to optimize the sound for when are
reading in your favorite chair, or while you work at your desk – all
positions that are unlikely to be “optimal” on their own.
By creating different listener positions that correspond to the main
locations from which you might use the system, you can optimize
the performance of the system for different situations, including
those in which you do not want to be limited to the primary
seating area.
The listener position section of the speaker menu allows you to give
a meaningful name to each position, and then to calibrate the
distances and output levels required to compensate for different
listening locations in the room.
Up to four listener positions can be defined. You can associate any
defined listener position with any sound profile you care to define.
See The Sound Profile Menu for more information on their use.
