BOSE Surround Sound System
for PCM and CDR-30.
®
The optional BOSE Surround
Sound System is compatible with
both the CDR-30 audio system,
which comes as standard,
and the optionally available PCM.
Developed specifically for
Porsche, it has been optimised for
the Cayman models. A total of
10 loudspeakers, including
an active subwoofer and central
speaker, and a seven-channel
digital amplifier with a total output
of 385 watts, combine to
produce a truly memorable sound
experience.
During audio playback from audio
or video DVDs (only in conjunction
with the optional PCM), the system
is able to make full use of the
impressive sound spectrum of 5.1
digital recordings. With music
in 5.1 digital format, the sound
has already been recorded in a
multi-channel format and is
faithfully reproduced exactly as
the original.

Five dedicated audio channels
(front left, front right, centre,
surround left, surround right)
deliver a sound that is as authen-
tic as it is natural. The digital
5.1 surround sound is balanced,
lifelike and crystal clear. It's
a sound that's as true to a live
performance or cinematic
experience as you can get.
Of course, you can still play
traditional music sources such
as CDs (only format supported
by CDR-30), either in stereo or
in one of the surround modes
generated by the patented BOSE
®
Centerpoint system. The
algorithm of Centerpoint
extracts an even more precise
and realistic sound from the
stereo signal.
®
The SurroundStage signal
processing circuitry developed
®
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 balanced surround
sound experience to both seat
positions.
To complement these features,
the BOSE
System offers a comprehensive
selection of equaliser presets for
customised sound. The dynamic
loudness function increases
bass levels as you decrease the
volume, thereby compensating for
the decreasing sensitivity of the
human ear at these frequencies.
Moreover, the AudioPilot
Compensation Technology uses a
microphone to continuously
measure the ambient noise inside
the vehicle and adapts music
playback automatically so that a
®
consistent sound is maintained in
all driving conditions.

only – alternative to the character-
