1. Mutauri: kuti ugone kutsungirira kukanganiswa kwekurova kwemoyo kwakasimba kamwe kamwe muchiratidzo chepurogiramu pasina kukuvara kana kukanganiswa. Heino kukosha kwekutarisa: simba remutauri rakasarudzwa rinofanira kunge rakapetwa katatu pane rekuverenga kwedzidziso.
2. Simba remagetsi: kana tichienzanisa ne transistor power amplifier, simba rinodiwa reserve rakasiyana. Izvi zvinodaro nekuti overload curve ye tube amplifier yakatsetseka. Pakukwirira kwechiratidzo chemimhanzi chakawandisa, tube amplifier haibudise pachena chiitiko chekucheka, asi inoita kuti muromo we peak uve denderedzwa. Izvi ndizvo zvatinowanzodaidza kuti flexible shearing peaks. Mushure me transistor power amplifier panzvimbo ye overload, nonlinear distortion inowedzera nekukurumidza, izvo zvinogadzira wave cutting yakakomba kune chiratidzo. Haiite peak denderedzwa, asi inoichenesa zvakanaka. Vamwe vanhu vanoshandisa compound impedance ye resistance, inductance uye capacitance kutevedzera loudspeaker, uye kuyedza kugona kwe output chaiyo kwemhando dzakasiyana dze high quality transistor power amplifiers. Mhedzisiro yacho inoratidza kuti kana mutoro uine phase shift, pane power amplifier nominal 100W, uye simba re output chaiyo i5W chete kana distortion iri 1%! Saka, kusarudzwa kwe reserve stock ye transistor power amplifier:
Amplifier yepamusoro-soro: kagumi
Amplifier yesimba repamusoro-soro rehurumende: katanhatu
Amplifier yesimba repakati nepakati: katatu ka4
Chinosimudzira simba rechubhu chinogona kuva chidiki zvikuru pane chiyero chiri pamusoro apa.
3. Kuti huwandu hupi hunofanira kusara padanho repakati pesimba reruzha uye huwandu hwesimba reruzha reruzha. Zvinofanira kuenderana nezviri mukati nenzvimbo yekushanda yechirongwa chekutepfenyura. Iyi 10dB shoma isingaderedzwe, yemimhanzi yemazuva ano yepop, bungee jumping nedzimwe mimhanzi, inofanirwa kusiya 20~25dB isingaderedzwe, kuitira kuti system yeruzha ishande zvakanaka. Ishande zvakachengeteka uye zvakatsiga.
