Angle

Depending on where the car radio is installed, the reading angle of the display can be adjusted to best suit the driver.

Audio output

The audio output power of a car radio or an exter- nal output stage measured according to different measurement standards.

RMS power:

Continuous power with a sine wave, measured at 10 % THD (DIN 45.324) for car radios or at 1 % THD (DIN 45.500) for ampliﬁers or another THD as in- dicated.

Music power:

Continuous power with a complex signal (music signal), measured at 10 % THD (DIN 45.324) for car radios or at 1 % THD (DIN 45.500) for ampliﬁers or another THD as indicated.

Max. power:

Maximum short-term output power possible, im- portant for extreme level peaks.

Bass Boost

The Bass Boost control can be used to adjust the bass reproduction of the ampliﬁer. The adjustment range normally extends from 0 dB to + 12 dB and ensures increased deep bass. Bass Boost permits rich, powerful base sound from relatively small subwoofer enclosure volumes.

Bluetooth (integrated)

Allows the wireless connection of a cell phone to the car radio to provide hands-free operation and call answer/termination via the radio. The cell phone must be equipped with a corresponding Bluetooth interface that meets the Bluetooth 1.2 standard and supports the so-called “hands-free proﬁle” (HFP 1.5).

Brightness

A menu is used to adjust the brightness of the dis- play and night design to the cockpit illumination. Separate settings can be selected for “headlights on” and “headlights off”.

Component system

2-way system, in which the chassis (tweeter, woofer, possibly subwoofer) can be installed se- parately to optimize the sound/installation situa- tion.

Corridor function

Thanks to the latest chip technology, the naviga- tion system stores all relevant data along the spe- ciﬁed driving route (corridor). Listen music from CD or MP3/WMA and navigate throughout Euro- pe fully dynamically (trafﬁc jam avoidance) at the same time, without changing CDs, as long as you do not leave the corridor.

signal

In principle, the DDA process mimics the reac- tions of an extremely quick, automatic directional antenna – similar to TV “rabbit ears” that deliver just “snow” or perfect reception depending on just a small adjustment. When used in car radios, the DDA process works with two independent antennas and receivers, whose signals are digi- tized using intermediate frequency analog-digital converters. The digitized data is then fed to an adaptive algorithm with extremely low response times. Thus, the two intermediate frequency sig- nals are combined so that the antenna can gain up to 3 dB of antenna power even for weak re- ception ﬁeld strength levels. In areas with strong reception, the second regular receiver, the so- called RDS background receiver, is then freely available. Switching between DDA operation and RDS background reception is quick and inaudible, controlled by a logic that evaluates the current reception conditions. This guarantees the radio listeners the best possible reception and rapid frequency switching at all times, without annoy- ing station searches.

system. The computer has enough power to handle the 4-channel self-adjustment of 27 graphic equa- lizer bands (= 108 bands in total). This creates a sound quality that remains unparalleled to date and can also be adjusted to your personal taste. Signal time alignment for the audio signal guaran- tees a true-to-life, concert-like panorama. Dyna- mic Noise Covering (DNC) automatically adjusts the volume, the equalizer and music dynamics to the current noise background in the vehicle. And this feature not only regulates the level, it also adjusts the sound to the frequency spectrum of the driving noise.

A spectrum analyzer, fascinating effect sound op- tions for Club, Stadium, Cathedral, Theater and Concert as well as sound presets round out the virtually unlimited opportunities to individualize your sound!

Parametric Bands in DEQmax/DEQmaxEX:

For especially easy operation and outstanding adaptation to the complicated acoustic condi- tions in modern vehicles, the DEQmaxEX equalizer uses six fully parametric bands (adjustable mid frequency, quality and level) with automatic cali- bration function (in systems with DEQmax, the parametric equalizer must be adjusted manually). In addition, you can also choose individually from

Aux input

Stereo preamp input to which external audio sources can be connected – e.g. a CD changer, MP3 player or the iPod via the iPod interface. As an alternative to the Aux input connection on the rear side of the system, the Front Aux input is a 3.5 mm stereo jack located conveniently on the front panel.

Aux naming

External sources, e.g., portable music players, can be assigned an arbitrary name (max. 16 charac-

mation on the artist, the name of the album and the names of the individual tracks. The CD-Text function can be used to show this information on the car radio display.

DAB antennas

In contrast to the familiar analog radio (AM/FM 0.145 – 108 MHz), digital radio is broadcast with its 2 bands (Band III 174 – 240 MHz, L-Band 1452 – 1492 MHz) in a higher frequency range. That is why it is necessary to add an antenna or replace the existing AM/FM antenna before it is possible to enjoy uninterrupted digital radio listening pleas- ure and the reception of extensive data services (news, trafﬁc messages, trafﬁc congestion maps, car park information, stock-market reports, display of artist and song title, etc.). In this department, Blaupunkt offers 5 different antennas to cover

After just a few seconds, the sound will be noticeably more harmonious, richer in detail with greater differentiation, as the annoy- ing frequency peaks are reliably balanced out.

Equalizers that do the thinking for you! The intelli- gent Blaupunkt equalizers are equipped with a self- adjusting function to automatically optimize sound reproduction. The DSAmax equalizer is a com- pletely integrated high-performance 24-bit DSP

Technology, whereby the car radio is based on signal/computer processors. The signal is digital- ly processed from the front-end receiver to the preamp output. This affords considerable advan- tages in terms of reception properties and sound adaptation.
