в случае 6 дискового кабасса это SAF7730HV

Описание SAF7730HV интригует:

The SAF7730 has a powerful suite of advanced IF signal and audio processing options. This includes sophisticated functions such as phase diversity and stereo generation from a mono source. State-of-the-art features such as enhanced equalization and delay-time management ensure superior audio processing, while integrated PACS, multipath detection and suppression, and antenna diversity contribute to bestin-class radio performance.

Key features
- Single-chip digital system solution for single and double tuner applications
- 650 MIPS for radio and audio processing
- Best-in-class radio reception with integrated digital PACS
- Digital interface for co-processor and upgradeable with HD Radio applications
- Simple customization
- Software-controllable radio and audio settings
- Supports Philips Software ‘Pure Studio’ and SRS’ Circle Surround II™ along with a wide range of other 3rd party software, such as Dedekind's LEF (Life Enhancement Filter) algorithm

Standard and optional hardware features
- Two 5th order Sigma-Delta IF ADCs for FM/AM/WB and FM/AM IBOC at 10.7 MHz
- IF signal quadrature mixing and downsampling and signal level generation
- Wideband output for external IBOC decoding
- Two RDS decoders
- Four Bitstream 3rd order audio Sigma-Delta Audio ADCs with anti-aliasing broadband input filter
- Four single ended and two high common mode or differential analog inputs selectable to be routed to the 4 Audio ADs
- Six multibit sigma delta DACs with 128-fold oversampling and noise shaping
- Host I2S I/O port with 4 outputs and 5 inputs, with option for slaving the DSP to external master sample rate
- Four independent I2S inputs and two independent SPDIF inputs with 5 channel Sample Rate Conversion

Many of the SAF7730’s inherent functions are software based:

Software functionality

At the heart of Philips’ software radio DSP devices – such as the SAF7730 – lies powerful software-driven functionality. As well as providing advanced radio and audio features, this also enhances easeof-design and creates a highly flexible and scalable solution, enabling implementation of a single platform across a global application range.
The following lists some of the features which are available either as standard or advanced options for the SAF7730.

Standard and optional radio software
- Switching antenna diversity
- Phase antenna diversity
- Enhanced multipath
- FM processing
- includes noise blanking, weak signal handling and variable
bandwidth control (digital PACS)
- AM processing
- includes noise blanking and weak signal handling
- Audio correlation
- Support for radio data systems including RBDS

Standard and optional audio software
- Dual media (rear seat audio)
- CD de-emphasis
- Super positioning of primary / secondary channels
- Compressor / expander
- 6 channel audio processing
- Graphic equalizer
- Spectrum analyzer
- Delay time management
- Incredible mono
Transforms a mono signal into stereo, enhancing the listening experience from either broadcast or recorded mono source material. One of the main advantages is a widening of the stereo field, increasing the sound’s spatial quality.
- Stereo++
Compensates for poorly defined stereo content from recorded sources or bad broadcast transmission, the Stereo++ module expands the source signal to improve stereo output.
- Adaptive UltraBass 2
Not a simple bass boost, this clever audio processing effect extends the low frequency range of acoustic systems. This makes the sound from small loudspeakers more impressive, giving the impression of larger, more powerful speakers.
- Elevation
Lifts the sound from speakers with a low physical location has the illusion of emanating from a higher position. This can be controlled to match the specific audio environment of any car model.

Интересно, что из этого есть в 281150017R?
