Signal time alignment
Asymmetrical sound Differentiated live-
impression at the concert sound impres-
driver's position sion at the driver's
without signal time position with signal
alignment time alignment
Electronically corrects the asymmetrical
seating position in the vehicle by delaying the
music channels so that the sound waves emitt-
ed by all the speakers reach the listener at the
same time. The signal time for the Bremen
MP74 can be adjusted right down to the last
centimetre. It is possible to select different
seating positions.
Silk dome tweeter
Silk dome tweeters use impregnated silk as
the cone material. Silk works with virtually no
annoying resonance of its own and delivers
a perfectly balanced frequency response. The
impregnation process gives the cone material
the stability it requires to handle high power
levels.
S/N – Signal/noise ratio
Maximum possible ratio of the music signal
to the basic noise, measured in decibels. The
higher the value, the better the quality of the
equipment.
Softkeys
Keys at the side of the car radio display that
are allocated different functions on the display
depending on the sound source or the operat-
ing menu, e.g. tuner station keys, CD Mix, Mag
Mix, Scan, AUD Bass, Treble, Balance, Fader,
Equaliser etc.
Sound presets
➞ Preset equalizer
Source tone memory
The settings for bass/treble can be adjusted
separately for each sound source to compen-
sate for differences in sound quality.
SPC (Spun Paper Cone)
The SPC, a development by Blaupunkt, is a very
stable, reliable paper cone. Thanks to a unique
polishing process and the mixture of 9 mineral
materials, the mechanical SPC exhibits a high
degree of stiffness. In terms of sound, it pro-
duces an extremely homogenous frequency
response without any noticeable cone resonan-
ce. The SPC is used for the ODce 20, ODce
20A, ODsb 8000A, GTb 300, GTx300 and GTb
300 Dual.
Speedometer signal
Impulses from the electronic speedometer
that are used to measure distances travelled
and for GALA.
Sub-Out
Separate preamp output with preceding low
pass.
Subsonic filter
The subsonic filter can be used with an ampli-
fier when a subwoofer is connected. It can be
set to protect the subwoofer from mechanical
overload due to low frequencies that cannot
be heard by the human ear. Thus, the subsonic
filter is able to increase the power handling
and the subjective maximum sound pressure
of the subwoofer.
The subsonic filter is used in all output stages
of the TS series and Velocity. A corresponding
adjustable filter can be switched on in the
Bremen MP74.
Subwoofer
Additional low bass speaker, which is driven
by an integrated or separate amplifier with a
low pass.
Subwoofer phase
Lets you switch the phase of the subwoofer
output to adjust it perfectly to the other
speakers.
Sub X-Over
Subwoofer crossover.

Telematics
Functions that a service provider makes
available via telecommunications, e. g. infor-
mation services with position transmission,
emergency call, breakdown call and off-board
navigation.
Telephone line-in
Separate aux-in to which a mobile telephone
can be connected for hands-free operation.
The caller's voice is heard on the car hi-fi
speakers.
Telephone mute
The car radio automatically switches to mute
as soon as an incoming telephone call is
detected. Prerequisite: the corresponding pin
in the connection box must be connected
with the car phone or the hands-free system
of the mobile phone.
Thermal Throttle
Circuit that reliably prevents amplifier shut-
down due to overload. It subtly varies the
voltage at the power supply to reduce heat
production without discernibly changing the
audio output volume, thus guaranteeing
reliable performance even when operated
continuously at maximum power levels.
