glossary dvd-audio the dvd-audio format provides audio fidelity far superior to that of normal cds in addition to audio in stereo and multi-channel surround sound dvd-audio discs can hold artist bios background information lyrics and liner notes wav wav files are used to store high-quality uncompressed audio data of cd-quality 44.1 khz/16-bit this file format requires a huge amount of memory ­ roughly 10 mb per minute of music compressed audio files such as mp3 and wma require significantly less memory but reproduce poorer quality sound audio cds are automatically saved in wav format in the windows operating system for perfect original sound quality without quality loss the formats and sampling frequencies that are supported by pioneer products are lpcm 16/22.05/24/32/44.1/48 khz and ms adpcm 22.05/44.1 khz dvd-video this multimedia digital technology guarantees second-to-none picture quality the ultra-sharp digital picture and surround sound bring impressive cinema into your car plus dvd is packed with useful features e.g multiple languages soundtracks and subtitles support for various multi-channel audio encoding technologies such as dts and dolby digital wma windows mediatm audio eject bookmark play a long press on the eject key sets an `eject bookmark the next time that dvd disc is inserted it will start playing from that point onwards wma is a music compression format developed by the microsoft corporation it uses the latest coding technologies to compress an original audio track minimising file sizes while maintaining good audio quality even at rates as low as 64 kb/sec av units and headunits l audio cd 45 w x 4 aac advanced audio coding aac is a wideband audio codec that dramatically reduces the amount of data needed to convey high-quality digital audio this makes it the audio format of choice for internet wireless and digital broadcast arenas aac provides more efficient audio encoding compression than older formats like mp3 yet delivers quality comparable to uncompressed cd audio pioneer co-developed and was the first to introduce this internal power chip that allows increased bass response and system clarity advanced dsp pioneer s advanced dsp and burr-brown 1-bit dac with 24-bit resolution produce the highest quality in-car sound flexible sound customisation can be achieved automatically equivalent to a professional system sound tuning perfection is enabled thanks to the burr-brown 1-bit dac with 24-bit resolution advanced auto time alignment optimises the sound field by acoustically adjusting the sound image depending on the listening position and auto equaliser monitors the car s interior acoustic environment and after one of the three target curves is chosen completes a sound correction process to balance the acoustics additionally the digital 13-band graphic equaliser s fine-tuning flexibility finds the perfect balance of lows mids and highs while the source eq memory effortlessly recalls tone settings you set for each individual audio source in addition there are 6-mode preset equalisation curves plus a nuance control function for subtle sound adjustments burr-brown 1-bit d/a converter with 24-bit resolution burr-brown s 1-bit d/a converter with 24-bit resolution offers a very wide dynamic range and an excellent signal-to-noise ratio giving more accurate and true-to-theoriginal sound sound quality is further enhanced by the use of high-quality audio capacitors and very low noise design cd-r/cd-rw compatibility all pioneer cd headunits can play back cd-r/cd-rw discs allowing you to enjoy your favourite compilations in-car use finalised music cd-r/cd-rw discs for playback in some cases cd-r/cd-rw discs may not play back correctly unless they have been recorded using a cd-r/cd-rw unit for recording music furthermore cd players may not play back music on cd-r/cd-rw discs recorded from a music cd-r/cd-rw recorder if there are scratches dirt or other characteristics specific to these discs or dirt or condensation on the pick-up lens text information such as titles recorded on cd-r/cd-rw discs may not be displayed read directions carefully regarding disc use before handling cd-r/cd-rw discs even if playback of a cd-r/cd-rw disc is possible it may take several seconds before actual sound reproduction begins asl automatic sound leveliser asl technology electronically and automatically adjusts volume and frequencies to mask varying degrees of exterior noise auto eq auto eq is a powerful sound tuning feature which uses a microphone to monitor and analyse the acoustics inside the car it then automatically adjusts the equalisation across the entire range of the music s frequency bandwidths to optimise the performance in addition it offers digital 13-band graphic equalisation for both front and rear speakers cd-r/cd-rw skip play allows you to skip misrecorded tracks on a cd-r/cd-rw disc first set skip id on the cd recorder unit and your car cd player will not play that particular track but skip to the next one on the disc auto time alignment the time alignment feature adjusts the speaker sound output timing within the vehicle for each speaker in steps of 2.5 cm so the sound from each speaker reaches the driver s ears at the same time auto time alignment automatically estimates the delay from each speaker to the listening position and adjusts the time alignment accordingly cd text use the cd text feature to view text information from a music compact disc which has been encoded with cd text data by pushing the display key you can scroll between disc titles track titles and artist name bmx bitmetric equaliser you ll be amazed at the difference in sound experience that the latest bmx and comp technologies make to compressed audio files such as mp3 and wma because some sound information gets lost during the compression process these digitised formats can sometimes sound unnatural unstable and flat tones can lack resonance and impact not any more bmx peps up digital compressed audio by adjusting the signal output level and tonal characteristics the result is a much more natural and comfortable sound bmx also improves the sound from uncompressed audio files particularly when the data originates from a poor original source comp and bmx cannot be used at the same time bmx does not improve modulation-like deteriorated sound typically found in low bit rate mp3 disc title memory enables you to programme an up to 10-digit descriptive title to be displayed when that cd is selected up to 48 titles may be entered with many pioneer single-cd units and up to 100 titles with pioneer multi-cd players its instant track selection gives the choice of programming any favourite cd track ­ for up to 24 tracks per disc selections are then played back utilising adps and the program button last position memory last position memory automatically resumes cd play from the last point where the cd was interrupted built-in dsp uses digital technology to correct a vehicle s interior acoustics the system also offers various sound fields to recreate different listening environments in your car studio jazz club etc mp3 popular compression format that allows large amounts of audio files to be stored onto one cd-r/cd-rw disc pioneer players come equipped with large buffering capabilities which means they are all able to handle data rates from 16 kbps and vbr variable bit rate recording digital compression this feature is useful for music with an exceedingly wide dynamic range classical is a good example quiet passages are boosted so that they don t get buried in background noise and loud passages are reduced preventing overload and distortion of the speakers random play cd playback mode mixes the order of songs and entire magazines in the case of mcd players providing a different sequence each time 99
