Mune iyoodhiyo system, kupisa kwemutauri unit imusoro kwazvo kune vashandisi veaudio, ingave iri munzvimbo yeKTV, kana bhawa uye chiitiko. Kazhinji, maonero akajairika ndeokuti kana vhoriyamu yemagetsi amplifier yakashandurwa zvakanyanya, zviri nyore kupisa mutauri. Kutaura zvazviri, pane zvikonzero zvakawanda zvinoita kuti mukurukuri atsva.
1. Kugadziriswa kusinganzwisisike kwevatauriuyemagetsi amplifiers
Shamwari zhinji dzinoridza odhiyo dzinofunga kuti simba rekubuda remagetsi amplifier rakakura kwazvo, chiri chikonzero chekukuvadza kune tweeter. Kutaura zvazviri, hazvisi. Muzviitiko zvehunyanzvi, mutauri anogona kushingirira kuvhunduka kukuru kwesimba rakapetwa kaviri simba rakayerwa, uye anogona kumira katatu nguva ipapo. Peak inovhundutsa zvakapetwa kaviri simba rakayerwa pasina matambudziko. Naizvozvo, kashoma kuti tweeter inopiswa nesimba repamusoro remagetsi amplifier, kwete nekuda kwesimba risingatarisirwe rakasimba kana kuchema kwenguva refu kwemakrofoni.
Kana chiratidzo chisina kukanganiswa, simba resimba rechiratidzo chenguva pfupi rakaremerwa rinowira pawoofer ine simba rakakwirira, izvo zvisingarevi kudarika simba renguva pfupi remukurukuri. Kazhinji, hazvizokonzere kutsauka kwekugovera kwesimba kwemukurukuri uye kukuvadza chikamu chemutauri. Naizvozvo, pasi pemamiriro ekushandiswa akajairwa, iyo yakatemerwa inoburitsa simba remagetsi amplifier inofanira kunge iri 1--2 nguva yakarongerwa simba remutauri, kuitira kuti ive nechokwadi chekuti amplifier yemagetsi haikonzeri kukanganisa kana simba remutauri rinoshandiswa.
2. Kushandiswa kusina kunaka kwefrequency division
Kusashandiswa kwakashata kweiyo frequency division point yeiyo yekuisa terminal kana yekunze frequency division inoshandiswa, kana iyo isinganzwisisike yekushanda frequency renji yemutauri zvakare chikonzero chekukuvadza kune tweeter. Paunenge uchishandisa frequency divider, iyo frequency division point inofanirwa kusarudzwa zvakanyatsoenderana neanoshanda frequency renji yemutauri akapihwa nemugadziri. Kana iyo crossover point ye tweeter inosarudzwa kuti ive yakaderera uye mutoro wesimba wakanyanya kurema, zviri nyore kupisa tweeter.
3. Kugadziriswa kusina kunaka kwekuenzanisa
Kugadziriswa kweiyo equator kwakakosha zvakare. Iyo frequency yakaenzana inoiswa kuti itsivise kukanganisa kwakasiyana kwemukati meinzwi ndima uye kusaenzana kwema frequency evatauri, uye inofanirwa kugadziriswa neiyo chaiyo spectrum analyzer kana zvimwe zviridzwa. Iwo ekutapurirana frequency maitiro mushure mekugadzirisa anofanirwa kuve akati sandara mukati meimwe siyana. Matuner mazhinji asina ruzivo rwehunyoro anogadzirisa pamadiro, uye kunyangwe vanhu vakati wandei vanosimudza yakakwira frequency uye yakaderera frequency zvikamu zveequalizer zvakanyanyisa, kugadzira "V" chimiro. Kana ma frequency aya akawedzera neanopfuura 10dB kana achienzaniswa neiyo midrange frequency (chiyero chekugadzirisa cheequalizer chinowanzo 12dB), kwete chete chikamu chinokanganisa chinokonzereswa neakaenzana chinozorarisa ruzha rwemimhanzi, asi zvakare kukonzera treble unit yeodhiyo Kupiswa kunze, rudzi urwu rwemamiriro zvakare ndicho chikonzero chikuru chekupisa vatauri.
- Kugadzirisa inzwi
Vazhinji vashandisi vanoisa attenuator ye post-stage simba amplifier pa -6dB, -10dB, kureva, 70% --80% yevhoriyamu knob, kana kunyange chinzvimbo chakajairika, uye kuwedzera kupinza kwepamberi kuti uwane vhoriyamu yakakodzera. Zvinofungidzirwa kuti mukurukuri akachengeteka kana paine muganho mune yemagetsi amplifier. Muchokwadi, izvi zvakare zvakaipa. Iyo attenuation knob yesimba amplifier inodzikamisa chiratidzo chekuisa. Kana iyo yekupinza yemagetsi amplifier yakaderedzwa ne6dB, zvinoreva kuti kuchengetedza vhoriyamu imwe chete, nhanho yekumberi inofanirwa kuburitsa 6dB yakawanda, voltage inofanira kupetwa kaviri, uye iyo yepamusoro ine simba yemusoro weiyo yekuisa, ichagurwa nepakati. Panguva ino, kana paine kamwe kamwe chiratidzo chikuru, chinobuda chicharemerwa 6dB kutanga, uye yakachekwa waveform ichaonekwa. Kunyangwe iyo amplifier yesimba isina kuwandisa, iyo yekuisa ndeye clipping waveform, iyo treble chikamu chinorema, kwete chete treble ndiyo yakakanganiswa, asi iyo tweeter inogona zvakare kupisa.
Patinoshandisa maikorofoni, kana maikorofoni iri padyo nemutauri kana yakatarisana nemutauri, uye vhoriyamu yeamplifier yemagetsi yakavhurwa zvine ruzha, zviri nyore kugadzira mhinduro yeruzha rwepamusoro-soro uye kukonzera kuchema, izvo zvinozoita kuti tweeter ipere. Nekuda kwekuti masaini mazhinji epakati uye anotenderera anotumirwa kubva ku treble unit mushure mekupfuura nepakati pe frequency divider, iyi yakakwirira-simba chiratidzo chese chinopfuura nepakati treble unit ine yakaonda kwazvo coil, ichigadzira hombe pakarepo, zvichikonzera kupisa kwepakarepo, uye kuridza izwi coil waya , iyo tweeter yakatsemuka mushure mekuita "woo" mhere mhere.
Nzira yakarurama ndeyekushandisa maikorofoni isiri pedyo kana kutarisana nechikamu chemukurukuri, uye simba rekusimudzira magetsi rinofanira kuwedzerwa zvishoma nezvishoma kubva padiki kusvika pahombe. Thegudzanzwiichakuvadzwa kana vhoriyamu yakanyanyisa, asi mamiriro ezvinhu anogona kuitika ndeokuti simba remagetsi amplifier harina kukwana uye gudzanzwi rinovhurwa zvakaomarara, kuitira kuti kubuda kweiyo amplifier yemagetsi kusava yakajairika sine wave, asi chiratidzo chine zvimwe zvinokonzeresa, izvo zvinopisa mutauri.
