(8 times oversampling) A digital filter which calculates 7 additional samples between the actual samples, which provides a closer representation the original analog signal, and therefore better sound quality.
A popular compression scheme used widely on the Internet. MP3 uses anywhere from 8kbps to 320kbps for compression, with the higher bit rates offering correspondingly better sound quality. Most software packages used to "rip" MP3s from CD audio (converting CD audio to MP3) allow for what's known as "ID3 Tags" — a text component of the digital music file which contains Track, Album, Artist, Genre, Year, and comment information.
Sony's proprietary SSIR-EX tuner technology which can actually adjust the tuner's bandwidth, depending on current environmental conditions. Improved sound quality and superior adjacent station interference rejection results.
Proprietary circuitry induces subtle phase shift in the preamp output of the head unit, different in each output channel, to simulate a sound source that is higher in origin. The frequency response in a section of the sound is altered, to further enhance the perception that the sound is originating from a physically higher source. These two factors, combine to seemingly raise the sound stage, and spread it wider across the dash, even if the speakers are mounted low in the doors.
Compatibility with the XM UniLink tuner. It plugs into the controller just like a changer, and operates through the head unit controls. Truly "plug-and-play".
A feature package that provides intuitive and safe source management for an audio and A/V system. Examples of specific Custom File features include Disc Memo, Station Memo, and Memo List.
A Sony proprietary amplifier chip that offers up to 52 watts maximum output (23.2 watts RMS) for crystal clear sound, that can overcome virtually any road noise over the full band of frequencies.
A proprietary Sony technology for CD and MD players. A circuit which monitors optical tracking and focus functions, among others, and actively adjusts those functions for optimal performance in real time.
A compact disc and player feature utilizing disc, track, and artist information encoded directly on the CD media. Both playback and media components must have CD Text compatibility.
A built-in equalization circuit providing three bands of frequency level adjustment, stored in 7 user-adjustable presets.
