Audio System

OVERVIEW
The audio system is available in three versions.
- Jaguar Sound System
- Jaguar 320W Premium Sound System
- Bowers & Wilkins 440W Surround Sound System
The audio systems are instrument panel mounted and combine the radio tuner with a slot loading single or 6 disc CD (compact disc) player. All units have AM/FM diversity reception, through the diversity antenna module, which receives signals from antennas located in the heated rear window. The audio systems have various levels of user control through the Touch-screen, ICP (integrated control panel) and steering wheel control panel. The Jaguar Sound System (base audio unit) with single CD (compact disc) player is only compatible with standard CD (compact disc)'s. All other versions of CD (compact disc) player are compatible with standard CD (compact disc)s and CD (compact disc)s with MP3 or WMA (windows media audio) files.
A portable audio module allows for the connection of a range of portable audio devices to the car's audio system. The portable audio module is controlled through the IAM (integrated audio module) and Touch-screen with play back through the car's speaker system. The introduction of this system allows the user to import their personal portable media player to interface with the car, including iPod and other MP3 players, or USB mass storage devices such as memory sticks. MP3 players can also be controlled through the Touch-screen if they are configured as mass storage devices. Details of how to do this will be contained in the manufacturers instructions.
The chosen audio device can be plugged into the car using an interface panel located in the floor console between the front seats. The interface includes a 3.5mm auxiliary jack-plug socket, a 12-volt power supply, a dedicated iPod connector with charging function, plus a USB2 connector which allows connectivity for a wide variety of USB devices. The USB port also provides a charging function although it does not support a USB hub. The maximum charging current supplied is 500ma. The user can connect an iPod and USB device at the same time, changing the source via the Touch-screen. The non selected source will still charge.
The Jaguar Sound System is the basic audio system which comprises of an IAM (integrated audio module) with no external amplifier and 8 speakers.
The Jaguar 320W Premium Sound System has the addition of an AUD 8 power amplifier and a 9 speaker system.
The Bowers & Wilkins 440w Surround Sound System additions include an AUD 12 power amplifier, a Dolby Pro-Logic 2 7.1 Surround Sound System, and 14 speakers.
DAB (digital audio broadcasting) is available for most European markets and gives access to digital radio channels for better sound quality and enhanced functionality depending on local service availability. The DAB (digital audio broadcasting) module is located in the luggage compartment. The system receives reception signals from the following sources to ensure optimum signal strength.
- DAB band L antenna located in the roof pod antenna module
- DAB band III antenna located in the heated rear window.
For NAS vehicles the digital format adopted is satellite radio which specifically links to the Sirius network. The system operates in the S-band frequency range, and as a result of the use of satellite transmission, has the ability to provide CD (compact disc) quality audio broadcasts over very large areas (typically continents). The satellite radio receiver is located in the luggage compartment. The system receives reception signals from the satellite radio antenna located in the roof pod module.
Primary user control of the audio system is via the ICP (integrated control panel) and the Touch-screen which are located in the center of the instrument panel. Control signals from the ICP (integrated control panel) are relayed on the medium speed CAN (controller area network) bus to the ICM (information control module). The ICM (information control module) relays the control signals to the rest of the audio system on the MOST (media oriented systems transport) ring. The ICM (information control module) is the timing master for the MOST (media oriented systems transport) ring and also hosts a gateway function between the medium speed CAN (controller area network) bus and the MOST (media oriented systems transport) ring. Audio output signals on the Jaguar 320W Premium Sound System and Bowers & Wilkins 440W Surround Sound System are sent on the MOST (media oriented systems transport) ring from the IAM (integrated audio module)
to the power amplifier for speaker output.
