DMS – Disc Management System
The Disc Management System makes it possible to connect a Blaupunkt CD changer and operate it using the car radio keypad.

Dual voice coil
In a dual voice coil, the two lengths of wire wound around the same former can be driven separately. This provides you with greater flexibility in the configuration of your system. In a parallel hook-up (= half the impedance), the amplifier connected is able to deliver double the performance at best. For sub- woofers that require a lot of power, each voice coil can be wired to a separate ampli- fier channel.
DualZone Audio
Devices equipped with dual zone audio have preamp outs on the back that lets you connect a second signal source (e. g. tuner from the front, CD playback from the back).
A separate adapter is required for the connec- tion of headphones and remote control for the second source.
DVD
Abbreviation of Digital Versatile Disc. Universal storage medium offered in a diverse range of formats (e. g. DVD-video, DVD-audio, DVD+R/RW, DVD-R/RW)
E
EON
Enhanced Other Networks.
➞RDS
Equalizer
Sound control, which adapts the frequency response on several frequency bands to accommodate less-than-perfect acoustic conditions and personal preferences.

EXP technology
EXP stands for “Extended Pole Piece”, i. e. the pole piece of the speaker magnets is extend- ed to allow greater linear excursion for the cone/voice coil while simultaneously reducing distortion.
Linear spektrum
EXP design
Other linear bandwidth for enhanced performance
F
Fader
Regulates the volume between the front and rear stereo channels.
Fibreglass Cone
The cones used in woofers and mid-range speakers must combine stiffness and minimal weight for the best linear behaviour. The Blaupunkt fibreglass cone offers particularly pleasing resonance characteristics for a very even frequency response.
FM Modulator
Functions in the same way as a small radio transmitter. It converts the incoming signals of such equipment as CD changers into radio waves in a selected frequency, which are fed into the car radio tuner through an adapter connected between the antenna input and the antenna plug. This makes it possible to connect a CD changer to any type of car radio.
FNM (Front Neodymium Magnet) Technology
Neodymium magnets are known for their compact, lightweight design. Thanks to neo- dymium magnets, it is now possible to build far lighter, flatter speakers with the same per- formance capabilities. The ultra-flat design is achieved through the use of FNM technolo- gy. With the neodymium magnet, which is installed in the front deep in the voice coil, the installation depth of the speaker is redu- ced by more than 30% and the mounting height for coaxial system set to close to 0 mm. FNM technology is used in all coaxial (ODx) and component systems (ODc) in the OD series.

GPS – Global Positioning System
25 satellites orbit the Earth. On the basis of the location data they transmit constantly, it is possible to use a trigonometric formula to determine the location of a vehicle, for example, anywhere on the Earth’s surface.
Gyroscope
Magnetically independent, electronic gyros- copic compass for the exact measurement of angles. Standard in airplane, ship and car navigation systems.
H
Hands-free operation
You can use the microphone and speakers in the car to place telephone calls without taking your hands off the wheel.
HDD – Hard Disk Drive
Head Unit
A term commonly used in the car hi-fi industry for a car radio in complex systems.
High pass
Active frequency crossover to control sub- woofer/satellite speaker systems, whereby the music signal is faded out below a selected frequency.
High-power output stage
Car radio output stage with 22 – 26 watts RMS (acc. to DIN 45 324) or 45 – 50 watts per channel of max. power, created by special high-power transistors.

ID 3 Tags
Information on artist, album, song, genre, etc. that can be stored with every MP3 file.
This information can be shown in the car radio display (comparable to CD-Text).
Installation kit
Mechanical adaptation of DIN car radios or speakers to different-sized, vehicle-specific installation locations. Blaupunkt offers a comprehensive programme with the perfect solution for each fitting problem.
Integrated Magnet System
To provide for greater stability, the speaker’s driver magnet is not screwed onto the back of the basket as usual, but rather integrated into the basket. This affords advantages not only for high-power-handling subwoofers, it also increases overall reliability.
IPP (Injected Polypropylene) cone
The IPP cone developed by Blaupunkt is a mechanically very stiff cone. With the addition of a synthetic material to the conven- tional PP cone, the injected IPP cone become noticeably stiffer and produces a louder, more linear and precise sound in the entire frequency response range. The IPP cone
is used in all coaxial, triaxial and component systems in the GT series and Th series.
IR remote control
A handheld or steering-wheel mounted remote control unit whose signal is transmitted in the invisible infrared range. Products that are mounted on the steering wheel have been certified by the German Technical Inspection Agency (TÜV).
