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 kukanganiswa kwechikamu kunokonzereswa neakaenzana kuchapenya zvakanyanya ruzha rwemimhanzi, asiwo nyore kukonzera treble. unit yeaudio Yakapiswa kunze, iyi mhando yemamiriro zvakare ndiyo honzeri huru yekupiswa kwevatauri.
- Kugadzirisa inzwi
Vazhinji vashandisi vanoisa attenuator yeiyo post-stage simba amplifier pa -6dB, -10dB, kureva, 70% --80% yevhoriyamu knob, kana kunyange chinzvimbo chakajairwa, uye kuwedzera kupinza kwekutanga nhanho kuti uwane inzwi rakakodzera.Zvinofungidzirwa kuti mukurukuri akachengeteka kana paine muganho mune yemagetsi amplifier.Muchokwadi, izvi zvakare zvakaipa.Iyo attenuation knob yesimba amplifier inodzikamisa iyo yekuisa chiratidzo.Kana iyo yekuisa yemagetsi amplifier yakaderedzwa ne6dB, zvinoreva kuti kuchengetedza vhoriyamu imwe chete, nhanho yekumberi inofanirwa kuburitsa 6dB yakawanda, magetsi anofanirwa kupetwa kaviri, uye iyo yepamusoro ine simba headroom 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 treble chete ndiyo yakakanganiswa, asi iyo tweeter inogona zvakare kupisa.
Patinoshandisa maikorofoni, kana maikorofoni iri padhuze nemukurukuri kana kuti yakatarisana nemutauri, uye vhoriyamu yeamplifier yemagetsi yakabatidzwa zvine ruzha, zviri nyore kugadzira mhinduro yeruzha rwepamusoro-soro uye kukonzera kuchema, izvo zvinokonzeresa. iyo tweeter yekupisa.Nekuda kwekuti masaini mazhinji epakati uye anotenderera anotumirwa kubva kune treble unit mushure mekupfuura nepakati pe frequency divider, iyi yakakwirira-simba chiratidzo chese chinopfuura nepakati treble unit ine yakaonda kwazvo coil, ichigadzira hombe nekukurumidza, zvichikonzera kupisa kwepakarepo, uye kuridza izwi coil waya , tweeter yakaputsika 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 yakawandisa, asi mamiriro angangoita ndeyekuti simba remagetsi amplifier harina kukwana uye gudzanzwi rinovhurwa zvakaomarara, kuitira kuti kubuda kweiyo amplifier yesimba kusiri kwakajairika sine wave, asi a. chiratidzo nezvimwe zvinoumba clutter, izvo zvinopisa mutauri.
