4. General Functional Description
a. Method of Operation
FastMute
Sonic XL
enables the connection of a navigation system (PNA, PDA, and PPC among others),
to the on-board loudspeakers of the vehicle in order to play the navigation announcements over those
loudspeakers. In the same way, FastMute
Sonic XL
can relay other desired audio signals via the vehicle
loudspeakers - for example, MP3-Players, DVD or telephone. FastMute
Sonic XL
also allows the
connection of a second audio source, in parallel.
b. Dynamic Loudspeaker Control
The new Flextime2© Mode controls the four loudspeaker channels dependent on the type of audio signal being
reproduced. For brief audio signals (under 15 seconds), such as are typical from Navi announcements, the
equipment remains in Short-Time-Mode and, about two seconds after the announcement has finished, switches
back to the auto radio. In this operating mode, only the front loudspeakers are controlled, therefore the
Radio/CD continues to be heard over the rear loudspeakers at the same time as the Navi announcement.
For longer audio signals that last over 15 seconds, such as the replay of MP3, talking books, or videos, the
equipment switches automatically into Long Time Mode. The switch back time, in this case, is about 20 seconds
and, after this interval, the equipment switches over to Short-Time-Mode.
As soon as the Long-Time-Mode is active, the rear speakers are used in addition to the front speakers for the
output of music via FastMute
Sonic XL
.An intelligent controller reduces the continual switching of the
car radio between songs or pauses in speech in videos to a minimum.
Using the Multiprofile-Bluetooth® Module „
BT Link 1
or
BT Link
“, active telephone calls are switched to
all the loudspeaker channels by FastMute
Sonic XL
.
Additionally, there is the option to suppress the switchover of the loudspeakers, for example where an external
Hands Free unit is used.
c. AutoPower-Function
Because, on many vehicles with Bus-Systems, there is no ignition signal available, FastMute
Sonic XL
provides automatic recognition of the radio switch-on. As soon as the radio is switched on, FastMute
Sonic
XL
is automatically activated.
An integrated switch-off delay keeps the system active for about 40 minutes after the radio is switched off. If an
audio signal is detected during the switch-off time, then the switch-off delay period is restarted. This function
ensures the correct operation of FastMute
Sonic XL
when the radio is switched off. At the end of the
switch-off delay time, the equipment switches to quiescent mode, to prevent possible battery discharge.
For vehicles without a radio, manual switch on/off via the ignition is possible.
