Yandisa

Ibhekisa ekubeni ingaba isithethi siyayixhasa na indlela yokufaka ngaxeshanye ye-multi-channel, nokuba kukho i-output interface yezithethi ezijikelezayo ezingasebenziyo, nokuba inomsebenzi wokufaka we-USB, njl. Inani lee-subwoofer ezinokudityaniswa nezithethi ezijikelezayo zangaphandle nalo linye yeendlela zokulinganisa ukusebenza kokwandiswa. Ii-interface zezithethi eziqhelekileyo ze-multimedia ziquka ikakhulu ii-analog interfaces kunye nee-USB interfaces. Ezinye, ezifana nee-optical fiber interfaces kunye nee-innovative digital interfaces, azixhaphakanga kakhulu.

Isiphumo sesandi

Iiteknoloji ze-hardware ze-3D ezixhaphakileyo ziquka i-SRS, i-APX, i-Spatializer 3D, i-Q-SOUND, i-Virtaul Dolby kunye ne-Ymersion. Nangona zineendlela ezahlukeneyo zokusebenzisa, zonke zinokwenza abantu bazive ngathi baneziphumo ezibonakalayo zentsimi yesandi esinemilinganiselo emithathu. Ezokuqala ezintathu ziqheleke ngakumbi. Abasebenzisa ithiyori ye-Extended Stereo, eyokucubungula isignali yesandi kwisekethe, ukuze umphulaphuli azive ukuba ulwalathiso lomfanekiso wesandi ludluliselwe ngaphandle kwezithethi ezibini, ukuze kwandiswe umfanekiso wesandi kwaye abantu babe nengqiqo yendawo kunye nobukhulu obuthathu, okubangela isiphumo se-stereo esibanzi. Ukongeza, kukho iiteknoloji ezimbini zokuphucula isandi: iteknoloji esebenzayo ye-servo ye-electromechanical (ngokuyintloko esebenzisa umgaqo we-Helmholtz resonance), iteknoloji yenkqubo yokuvelisa isandi ye-BBE ephezulu kunye netekhnoloji ye-"phase fax", enefuthe elithile ekuphuculeni umgangatho wesandi. Kwizithethi ze-multimedia, iiteknoloji ze-SRS kunye ne-BBE kulula ukuzisebenzisa kwaye zineziphumo ezilungileyo, ezinokuphucula ukusebenza kwezithethi ngempumelelo.

Ithoni

Ibhekisa kwisignali enobude be-wavelength (iphitshi) obuthile nobuhlala buzinzile, ngokwentetho eqhelekileyo, ithoni yesandi. Ixhomekeke kakhulu kubude be-wavelength. Kwisandi esinobude be-wavelength obufutshane, indlebe yomntu iphendula ngephitshi ephezulu, ngelixa kwisandi esinobude be-wavelength obude, indlebe yomntu iphendula ngephitshi ephantsi. Utshintsho kwiphitshi enobude be-wavelength ngokusisiseko luyi-logarithmic. Izixhobo ezahlukeneyo zidlala inothi efanayo, nangona i-timbre yahlukile, kodwa iphitshi yazo iyafana, oko kukuthi, igagasi elisisiseko lesandi liyafana.

I-Timbre

Ukuqonda umgangatho wesandi kukwayindlela eqhelekileyo yesandi esinye esahlula kwesinye. Xa izixhobo ezahlukeneyo zidlala ithoni efanayo, isandi sazo sinokuhluka kakhulu. Oku kungenxa yokuba amaza azo asisiseko afana, kodwa izinto ezihambelanayo zahlukile kakhulu. Ke ngoko, isandi asixhomekekanga kuphela kwisandi esisisiseko, kodwa sinxulumene kakhulu nee-harmonics eziyinxalenye ebalulekileyo yesandi esisisiseko, esenza isixhobo ngasinye somculo kunye nomntu ngamnye babe nesandi esahlukileyo, kodwa inkcazo yokwenyani ixhomekeke ngakumbi kwisiqu kwaye isenokuvakala ingaqondakali.

I-dynamic

Umlinganiselo wesandi esomeleleyo nesobuthathaka kwisandi, esichazwa kwi-dB. Umzekelo, ibhendi inoluhlu olutshintshayo lwe-90dB, oko kuthetha ukuba inxalenye ebuthathaka inamandla angaphantsi kwe-90dB kunenxalenye enomsindo. Uluhlu olutshintshayo luluhlu lwamandla kwaye alunanto yakwenza nenqanaba elipheleleyo lesandi. Njengoko bekutshiwo ngaphambili, uluhlu olutshintshayo lwezandi ezahlukeneyo kwindalo nalo luyaguquguquka kakhulu. Isignali yentetho ngokubanzi imalunga ne-20-45dB kuphela, kwaye uluhlu olutshintshayo lwezinye iisymphonies lunokufikelela kwi-30-130dB okanye ngaphezulu. Nangona kunjalo, ngenxa yemida ethile, uluhlu olutshintshayo lwenkqubo yesandi alufane lufikelele kuluhlu olutshintshayo lwebhendi. Ingxolo yendalo yesixhobo sokurekhoda imisela isandi esibuthathaka esinokurekhodwa, ngelixa umthamo ophezulu wesignali (inqanaba lokuphambuka) kwenkqubo unciphisa isandi esomeleleyo. Ngokubanzi, uluhlu olutshintshayo lwesignali yesandi lubekwe kwi-100dB, ngoko uluhlu olutshintshayo lwezixhobo zesandi lunokufikelela kwi-100dB, nto leyo ilungile kakhulu.

Iiharmoniki zizonke

Ibhekisa kwiinxalenye ezingaphezulu ze-harmonic zesignali yokuphuma ezibangelwa ziinxalenye ezingezizo ezilandelelanayo kunesignali yokufaka xa umthombo wesignali yesandi udlula kwi-amplifier yamandla. Ukuphazamiseka kwe-harmonic kubangelwa kukuba inkqubo ayilulo olulandelelanayo ngokupheleleyo, kwaye siyichaza njengepesenti yesikwere esiphakathi kweengcambu ze-harmonic component entsha eyongeziweyo kwixabiso le-rms yesignali yokuqala.
