Wedzera

Zvinoreva kana mutauri anotsigira akawanda-channel panguva imwe chete yekupinza, kana paine inobuda interface yevasina kutenderedza vatauri, ingave ine USB yekupinza basa, nezvimwewo. Huwandu hwema subwoofers anogona kubatanidzwa kune ekunze surround speaker ndeimwe ye maitiro ekuyera kuwedzera kwekuita.Iyo yekupindirana kweakajairwa multimedia vatauri anonyanya kusanganisira analog interfaces uye USB interfaces.Zvimwe, senge optical fiber interfaces uye innovative digital interfaces, hazvina kunyanya kuwanda.

Tone

Zvinoreva chiratidzo chine chaiyo uye kazhinji yakagadzika wavelength (pitch), kutaura kwecolloquially, toni yeruzha.Zvinonyanya kuenderana newavelength.Nokuda kwenzwi rine urefu hupfupi, nzeve yomunhu inodavidza nenzwi rakakwirira, nepo nokuda kweinzwi rine urefu hwakareba, nzeve yomunhu inodavidza neinzwi rakaderera.Shanduko yepitch ine wavelength ndeye logarithmic.Zviridzwa zvakasiyana zvinoridza noti imwe chete, kunyange zvazvo timbre yakasiyana, asi kukwirira kwadzo kwakafanana, kureva kuti, masaisai eruzha rwakafanana.

Timbre

Maonero emhando yenzwi zvakare hunhu hwehumwe ruzha hunoisiyanisa kubva kune imwe.Kana zviridzwa zvakasiyana zvichiridza toni imwechete, timbre yavo inogona kunge yakasiyana.Izvi zvinodaro nekuti masaisai avo akakosha akafanana, asi zvikamu zve harmonic zvakasiyana.Naizvozvo, iyo timbre haingotsamira pane yakakosha masaisai, asi zvakare yakanyatso hukama kune harmonics iri chikamu chakakosha cheiyo fundamental wave, iyo inoita kuti chiridzwa chemimhanzi chega chega uye munhu wega ave netimbre yakasiyana, asi iyo rondedzero chaiyo inonyanya kuzviisa pasi. uye anogona kunzwa Asi asinganzwisisiki.

Dynamic

Reshiyo yeakasimba kune asina kusimba muruzha, inoratidzwa mu dB.Semuenzaniso, bhendi rine simba re 90dB, zvinoreva kuti chikamu chisina simba chine 90dB simba shoma pane chikamu chine ruzha.Dynamic range ndiyo reshiyo yesimba uye haina chekuita nehupamhi hwezwi.Sezvambotaurwa, kushanduka kwemazwi akasiyana-siyana mumasikirwo anosiyanawo zvikuru.Chiratidzo chekutaura chinenge 20-45dB chete, uye simba remamwe masimphoni anogona kusvika 30-130dB kana kupfuura.Nekudaro, nekuda kwezvimwe zvipimo, iyo ine simba renji yeinzwi system kashoma kusvika kune inochinja yebhendi.Ruzha rwemukati rwechishandiso chekurekodha chinotarisa ruzha rusina kusimba runogona kurekodhwa, nepo huwandu hwechiratidzo chepamusoro (kukanganisa nhanho) yegadziriro inodzikamisa ruzha rwakasimba.Kazhinji, simba rekuchinja kwechiratidzo chezwi rinoiswa ku100dB, saka iyo inoshanduka yemidziyo yekuteerera inogona kusvika ku100dB, iyo yakanaka kwazvo.

Total harmonics

Inorevera kune ekuwedzera harmonic zvikamu zveinobuda siginecha inokonzerwa neasina mutsara zvikamu pane yekuisa chiratidzo kana odhiyo chiratidzo chinopfuura nepamagetsi amplifier.Harmonic distortion inokonzerwa nenyaya yekuti iyo system haina kunyatso mutsara, uye tinoiratidza sechikamu chechikamu chemudzi wepakati weiyo ichangobva kuwedzerwa yakazara harmonic chikamu kune rms kukosha kwechiratidzo chepakutanga.
