Using PAV/PDSD
setting the volume Normally, when you wish to change the volume, you want all the speakers to
move up or down together, maintaining their relative balance. Thus the volume
control will operate as a
master volume by default.
Occasionally, you may want to change the volume of some speakers relative to
others; for example, you may want to increase the level of the rear speakers a bit
for more dramatic surround effects. To do so, press the
rear button, followed by
the volume button while the light about the rear button is still lit. Similar two-
step operations work for center, subwoofer and balance as well.
If you have made a relative adjustment and wish to adjust the master volume
without waiting for the system to timeout and return to its default, pressing
mas-
ter will allow you to immediately adjust the master volume.
home thx cinema ® THX cinema ® indicates that the proprietary Home THX audio processing circuits
are in use in addition to whatever multichannel audio is appropriate for the
source in question. This can include Dolby Digital, DTS, or Dolby Pro Logic (ei-
ther analog or digital). In the case of discrete multichannel sources (anything
other than Pro Logic), THX 5.1 will be employed automatically; in the case of Pro
Logic, THX 4.0 is used.
THX cinema is most appropriate for film-based program materials made since the
mid-1970’s, which have (in all likelihood) been mixed in a standard dubbing
stage environment. This setting will provide the listener with the most accurate
reproduction of the majority of motion pictures available. In addition, many other
video source materials are produced in Dolby Surround using the industry stan-
dard response curves, and are best enjoyed in the
THX cinema mode. (Examples
include Star Trek: Voyager and The David Letterman Show, which are mixed in an
environment which emulates the dubbing stage used for film.)
THX cinema includes several specific technologies designed to more accurately
reproduce film soundtracks:
• Re-Equalization™: corrects for the overly bright front channels
commonly found in film soundtracks
• Electronic Crossover: designed to work optimally with THX-
certified speakers to enhance low frequency dynamic range (espe-
cially improtant with multichannel digital sources such as Dolby
Digital)
• Adaptive Decorreltation™: enhances surround spaciousness
and envelopment only when necessary (based on the soundtrack
itself)
• Bass Peak Level Manager™: keeps low frequency transients un-
der control to minimize the opportunity for amplifier or speaker
overload.
• Loudspeaker Position Time Synchronization™: ensures a
coherent, time-aligned soundfield.
