Sound system
The sound systems are based on the sound systems in the TT Coupé ‘07 (refer to SSP 382).
Basic sound
The basic sound system with four loudspeakers in
combination with the chorus radio is identical to
the basic sound system in the TT Coupé.
It uses the audio amplifier in the Chorus radio. The Chorus radio does not evaluate the convertible
top position. The loudspeakers cannot be muted
during convertible top operation.
Standard sound
The standard sound system has been slightly
modified compared to the system in the TT Coupé.
The software of the "digital sound package
control unit J525" (amplifier) has been extended
for the roadster to include the following features:
– Sound tuning for convertible top open and
closed
To ensure an optimum sound both when the
convertible top is open and closed, sound
tunings have been configured for these
convertible top conditions.
In the case of the manual convertible top, the
digital sound package control unit J525
evaluates a CAN message from the onboard
power supply control unit J519. In the case of the
automatic convertible top, the digital sound
package control unit J525 evaluates a message
from the convertible top operation control unit
J256. The sound set-up is changed over when
opening and closing the convertible top at the
start of the door glass operating cycle. Sound
output is muted briefly to ensure a pleasant
transition for the listener. The duration of muting
is similar to that when changing radio stations
using the station keys.
– Sound correction during phone calls or voice
control of the Navigation plus
The digital sound package control unit J525
evaluates CAN messages from the telephone
transmitter and receiver unit R36 or the
Navigation plus system with voice control and
thereupon sets the sound system to optimum
voice quality.
This amplifier will also be installed in the TT Coupé
from autumn 2006.
The loudspeakers are identical to the loudspeakers
in the TT Coupé.
BOSE Surround Sound
The amplifier in the BOSE sound system has also
been adapted for use in the Roadster.
The software modifications are identical to the
modifications to the standard amplifier (see above).
This amplifier will also be installed in the TT Coupé
in combination with software version 120 or higher.
The BOSE Audio Pilot technology is ideal for a
roadster. It measures the ambient noise with a
microphone and the adjusts volume and sound in
the amplifier so that the listener does not perceive
any change in sound quality. The subwoofer is built into the TT Roadster in the
rear bulkhead of the occupant cell, on the right
adjacent the optional ski bag. All other loudspeakers
are identical to the loudspeakers in the TT Coupé.
