BOSE
®
Surround Sound system.
The optional Bose
®
Surround
Soun d system was specially
developed fo r the 911 a nd is,
therefore, perfec tly tuned to the
car’s specific interior acoustics.
A total of 13 lou dspeakers
(12 in the Cabriolet and
911 Targa 4 models), inclu ding
an active subwoofer and
central speaker, and a seven-
channel digital amplifier with
a rated outp ut of 385 watts,
combine to produce a truly
memorable sound experi ence.
During audio playback from audio
or video DVDs, the system is able
to make full use of the impressive
sound spectrum of 5.1 digital
recordings. With music in the 5.1
format, the sound has al ready
been recorded in a multichannel
format and is faithfully re produced
ex actly as the ori ginal.
Five dedicated audio channels
(front left, front right, center,
surround left, surrou nd right)
deliver a sound that is as auth entic
as it is natural. The digital
5.1 sur ro und sound is balanced,
life like and crystal clear. A 360-
degree sound experience that
is as close to a live performance
as you could imagine.
Of course, you can still play
trad itional music sources such
as CDs, either in stereo or in
one of the surround modes
generated by the patented
Bo se
®
Centerpoint
®
system.
The algorithm of
Centerpoint
®
2
extracts a precise and realistic
sound from the stereo signal.
The SurroundStage
®
signal
processing circuitry develo ped
by Bose
®
assigns each individual
audio channel, whether sourced
from a DVD or generated by
Centerpoint
®
, to a selected
combination of loudspeakers
and is, therefore, able to
deliver an optimally balan ced
surround-sound experience
to all seat positions.
To com plement these features,
the Bose
®
Surround Sound
system offers a comprehensive
selection of equalizer presets for
cu stomized sound. The dynamic
loudness function inc reases
bass
levels as you decrease the
volume, thereby compensating
for the decreasin g sensitivity
of the human ear at these
frequencies. Moreover, the
AudioPilot
®
Noise Compensation
Technology uses a microphone
to continuously measure
the ambie nt noise inside the
vehicle and a dapts m usic
playback automatically so that a
consistent sound is maintained
in all driving cond ition s.
In short, welcome to your
very own concert hall—one
of the fastest around.
