This technologybreaks up a music signal into 5.1 channels forrecording and playback: left front, right front, center,left surround, right surround and subwoofer(0.1 channel). Because this technology makes itpossible to store a large amount of audio data on adisc efficiently, it is used to record audio in multiplelanguages, in stereo or monaural.Dolby SurroundThis is a system that records a 4-channel signal (leftfront, right front, center, monaural surround) in2 channels, and then uses a Dolby Pro Logicdecoder to decode the resulting signal back into4 signals for output. The surround channel output ismonaural.Linear PCM Audio (LPCM)This is a signal recording format that is used formusic CDs. Music CDs are recorded at 44.1 kHz/16 bits, DVD video discs are recorded at44.1 kHz/16 bits to 96 kHz/24 bits.MPEGMPEG is an international standard format for thecompression of motion video as defined by theMoving Picture Experts Group, a working committeewhich functions under the auspices of theInternational Standardization Organization andInternational Electrotechnical Commission.On some DVD discs, the digital sound iscompressed using this system before it is recorded.Playback Control (Video CD)When a video CD package is labeled as “supportsplayback control”, etc., the user can display a menuscreen on the TV and interactively access certainscenes and information.Sampling Frequency, Number of Quantization BitsWhen an analogue signal is converted into a digitalsignal, the signal is divided into fixed time intervalsand digitized. This method is called “sampling”. Thesampling frequency indicates how many intervals1 second is divided into; the number of quantizationbits indicates the size of the data that is used torepresent each interval. The larger these figures are,the more faithfully the analogue sound can bereproduced.Titles and Chapters (DVD Video))A DVD is divided into several large divisions (titles),and several smaller divisions (chapters). Thesedivisions are assigned numbers, allowing the userto easily specify where he or she wants to startplayback.Example) DVD videoTracks (Video CD, Music CD)Video CDs and music CDs are divided into severaldivisions (tracks), each of which is numbered.Example)Pan & Scan ScreenThis is one method for displaying wide-screen videoon a normal sized (4:3) TV; in this view, the left andright edges of the screen are cut off.Letterbox ScreenThis is one method for displaying wide-screen videoon a normal sized (4:3) TV; in this view, black bandsappear at the top and bottom of the screen.Power supply voltage : 12 V DC, - ground(test voltage: 14.4 V)Current consumption : Less than 8.5 A(during discoperations at ratedoutput)Power output : 20Wa4 ch (1 kHz,1 %, 4 ≠)Maximum output : 45 Wa4 chSuitable speaker impedance : 4 ≠Audio input impedance : 10 k≠Audio input sensitivity : 200 mVPre-out output voltage : 5 VrmsPre-out output impedance : 60 ≠External dimensions(Main unit) : 7za1 15 /16za6 1/8z(WaHaD) (178a50a155 mm)(Power amplifier unit) : 57/8za1 5/8za4 5/16z(WaHaD) (150a42a110 mm)Weight(Main unit) : 3 lbs. 10 oz (1.65 kg)(Power amplifier unit) : 24 oz.
