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.

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.

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.

A system developed by Blaupunkt with a digi- tal voice memory that can record up to 4 traf- fic messages with a total length of 4 minutes. The TIM® memory updates itself continually.
A function that even works when the car radio is switched off in a freely selectable time frame.
Impulses from the electronic speedometer that are used to measure distances travelled and for GALA.
