The following components are described for the Bang & Olufsen High End Surround Sound System:

-

High End audio amplifier (AMPT)

-

-

Controller (CON)

-

Extendible dashboard speaker

High End audio amplifier

High End audio amplifiers (AMPT) are audio amplifiers with active frequency diplexers. Active frequency diplexers achieve better acoustic results than passive frequency diplexers. The speakers that are suitable for the frequency are selectively activated. The active frequency diplexers transfer from the audio amplifier only the frequency range that can be optimally played back by the relevant connected speaker.

In F13, the active 16-channel High End audio amplifier (AMPT) supplies the following 16 speakers with a maximum power output of 1300 watts:

-

7 tweeter, 12.5 watts

-

7 mid-range speakers, 75 watts

-

2 bass speaker, 250 watts

The High End audio amplifier (AMPT) is a control unit in the MOST network with the following functions:

-

Audio amplifier for high and mid-range speaker

-

Audio amplifier for bass speaker

The class-D audio output stages of the High End audio amplifier (AMPT) have a significantly higher efficiency and therefore result in reduced power loss compared with traditional audio output stages.

Headunit

In principle, the structure of the headunit corresponds to that of a personal computer. Like a personal computer, the headunit contains the following components:

-

Processor

-

Working memory

-

Hard disk

-

Fan

The hard disk in the headunit is used to store the application software and other data.

The following applications are installed on the hard disk:

-

Music library

The music collection is based on the audio data stored on the integrated hard disk.

-

Music track database

Software for track identification using a music track database (Gracenote®).

-

Navigation system (map data) and software (application software)

Full screen display possible: Zoomable assistance window with map view, journey planner, map data storage on the hard disk.

-

Voice processing system

-

Office (database with addresses)

The data is used for telephone and navigation, for example.

The headunit is the central control unit for the listed applications. For the purposes of picture signal transmission, the headunit is linked to the Central Information Display (CID). The headunit is also connected to the controller (CON). The controller (CON) is the control panel for the Central Information Display (CID).

When pressed, the ”Back” button returns the user to the last screen mask.

The ”Option” button enables other settings in the last selected submenu.

Extendible dashboard speaker

The extendible dashboard speaker is a combination of a mid-range speaker and an acoustic lens for the tweeter. The extendible dashboard speaker extends upwards when the audio system is switched on. The extendible dashboard speaker can be illuminated according to the settings under "Bang & Olufsen" light setting.

Speakers

The speakers in the Bang & Olufsen High End Surround Sound System are directly connected to the audio amplifier.

The tweeters are fitted with a ceramic dome driver. This ceramic dome driver ensures optimal radiation patterns. The mid-range speakers and the bass speakers are fitted with a hexagon diaphragm for extreme pulse fidelity and linearity.

All visible speakers can be illuminated according to the settings under "Bang & Olufsen" light setting. The front bass speakers are not illuminated and are located under the driver's seat and the front passenger seat respectively.

Microphone

The microphone records the prevailing noises in the passenger compartment in order to modify the audio playback in terms of volume and tone.

The following graphic shows the installation location of the microphone cover for F13.

System functions

The following system functions are described for the High End audio amplifier:

-

Electronic power-up

-

Electronic power-down

-

Undervoltage cutout

-

Bang & Olufsen light setting

-

Bang & Olufsen tone setting

-

Automatic volume and tone setting

 

Electronic power-up

The High End audio amplifier is connected with "terminal 30" and ground for voltage supply. The audio amplifier is woken up using the MOST bus. The audio amplifier is active under the following preconditions:

-

Control input identifies voltage greater than 9 volts

-

"Terminal 30" input identifies voltage that is greater than the voltage at the control input.

 

Electronic power-down

The High End audio amplifier is connected with "terminal 30" and ground for voltage supply. The audio amplifier has an operating voltage range of 7.5 to 16 volts at the control input.

At voltages of less than 7.5 volts at the control input, the audio amplifier is automatically switched off. This ensures that the audio amplifier does not remain switched on, for example in a parked vehicle.

Undervoltage cutout

The High End audio amplifier is automatically switched on at engine start as soon as the voltage falls below the operating voltage range.

Once the switch-on conditions are satisfied again, the High End audio amplifier is automatically switched on again.

Bang & Olufsen light setting

The lighting effect visually highlights the High End hi-fi system in the dark. This is achieved through indirect lighting of the cover of the visible speakers. Activation of the lighting is regulated by a light control unit in the High End audio amplifier. Only the front bass speakers are fitted with indirect lighting.

Using the controller (CON), you can choose from 3 light settings on the Central Information Display (CID) under "Bang & Olufsen" light setting. The following options are available:

-

On

-

Off

-

Reduction while driving

 

Bang & Olufsen tone setting

Using the controller (CON), you can choose from 2 specific tone settings on the Central Information Display (CID) under "Bang & Olufsen" tone setting. The following options are available:

-

Studio

The "Studio" tone setting is used to perform the frequency-corrected and phase-corrected output of the audio signals in the speakers.

-

Expanded

The "Expanded" tone setting is used to achieve an open and lively tone in the passenger compartment.

 

Automatic volume and tone setting

Using continuous microphone measurement, the High End audio amplifier identifies annoying tyre or wind noise. The High End audio amplifier dynamically adjusts the volume and the sound quality accordingly. The "Speed Volume" setting is thereby replaced.

Notice! Surround sound functions are not recommended under certain circumstances!

The surround sound function is not recommended for predominantly voice reproduction or poor radio reception.
