• Loudspeaker Position Time Synchronization™: ensures a
coherent, time-aligned soundfield.
When in doubt as to whether THX processing should be included, listen for a
natural presentation of the treble. Films mixed for theatrical release exhibit an el-
evated treble region when played back on a home system with flat response. The
THX mode will correct this. Conversely, surround-encoded programs without this
high frequency emphasis might sound dull or lacking in detail when (incorrectly)
played in the THX mode.
Dolby Digital The AVP2 automatically detects Dolby Digital 5.1 channel recordings and decodes
them appropriately to give you five discrete channels of information plus a Low
Frequency Effects (LFE) channel. This LFE channel is sometimes called the “.1”
channel, due to its limited bandwidth as compared to the other channels, all of
which are full range.
The sophisticated bass management provisions in your AVP2 takes these five full
range signals plus the deep bass information in the LFE channel, and redirects all
this information to whatever speakers can actually reproduce it. Bass management
both ensures that you can actually hear what you were intended to hear, and sig-
nificantly reduces distortion that likely would result otherwise from bass-limited
speakers being overloaded by deep bass they were never intended to reproduce.
The result is cleaner, more full-bodied sound than would otherwise be available
from most systems.
Dolby Digital Surround EX The AVP2 also automatically detects Dolby Digital Surround EX recordings. Sur-
round EX recordings have a sixth, “center back” channel “hidden” in the two dis-
crete surround channels, along with a “flag” in the identify the signal to the pro-
cessor. For this reason, Surround EX is sometimes called a “6.1 channel” system. It
may be used with 5.1, 6.1, or 7.1 channel speaker systems.
If you have both surround and either one or two rear channels defined in your
speaker configuration, the AVP2 will retrieve this “extra” information and send it
to the appropriate speaker(s). If you do not have surround and rear speakers, this
“extra” information is folded into the existing surround speakers so you can still
hear it, though of course it may not image exactly as intended (since you lack
the extra speakers.)
The sophisticated bass management provisions in your AVP2 takes these five, six,
or seven full range signals plus the deep bass information in the LFE channel,
and redirects all this information to whatever speakers can actually reproduce it.
Bass management both ensures that you can actually hear what you were in-
tended to hear, and significantly reduces distortion that likely would result other-
wise from bass-limited speakers being overloaded by deep bass they were never
intended to reproduce. The result is cleaner, more full-bodied sound than would
otherwise be available from most systems.
DTS The AVP2 automatically detects DTS 5.1 channel recordings and decodes them
appropriately to give you five discrete channels of information plus a Low Fre-
quency Effects (LFE) channel. This LFE channel is sometimes called the “.1” chan-
nel, due to its limited bandwidth as compared to the other channels, all of which
are full range.
