Muhurongwa hwemanzwi, kutsva kweyuniti yemanzwi kunonetsa zvikuru vashandisi vemanzwi, kungave kuri panzvimbo yeKTV, kana pabhawa nepanzvimbo. Kazhinji, maonero akajairika ndeekuti kana vhoriyamu yepower amplifier yakakwira zvakanyanya, zviri nyore kutsva spika. Kutaura zvazviri, pane zvikonzero zvakawanda zvinoita kuti spika inyanye kutsva.
1. Kurongeka kusina musoro kwemasipikauyema amplifiers emagetsi
Shamwari zhinji dzinoridza odhiyo dzinofunga kuti simba rekuburitsa re amplifier yesimba rakakura zvakanyanya, izvo zvinova chikonzero chekukuvadzwa kwe tweeter. Kutaura zvazviri, hazvisizvo. Muzviitiko zvehunyanzvi, mutauri anogona kugara achitsungirira kuvhunduka kukuru kwechiratidzo kaviri simba rakatarwa, uye anogona kugara katatu ipapo ipapo. Kuvhunduka kwakanyanya kaviri simba rakatarwa pasina matambudziko. Saka, hazviwanzoitiki kuti tweeter itsve nesimba guru re amplifier yesimba, kwete nekuda kwekukanganisa kwakasimba kusingatarisirwi kana kurira kwenguva refu kwemakrofoni.
Kana chiratidzo chisina kukanganiswa, simba remagetsi rechiratidzo chakawandisa kwenguva pfupi rinowira pawoofer nesimba rakawanda, izvo zvisingapfuure simba remagetsi remutauri kwenguva pfupi. Kazhinji, hazvizokonzere kutsauka kwekugoverwa kwesimba remutauri uye kukuvadza unit yemutauri. Saka, mumamiriro ekushandiswa kwakajairika, simba remagetsi rinobuda remutauri rinofanira kuva ka1--2 simba remutauri, kuitira kuti ive nechokwadi chekuti simba remutauri harikonzere kukanganiswa kana simba remutauri richishandiswa.
2. Kushandiswa zvisina kunaka kwekupatsanura mafrequency
Kusashandisa zvakanaka nzvimbo yekuparadzanisa mafrequency yemuchina wekupinda kana paine nzvimbo yekuparadzanisa mafrequency ekunze, kana nzvimbo isina kurongeka yemutauri, zvinogonawo kukonzera kukuvara kwemutauri. Paunenge uchishandisa muchina wekuparadzanisa mafrequency, nzvimbo yekuparadzanisa mafrequency inofanira kusarudzwa zvichienderana nehuwandu hwemafrequency emutauri hunopiwa nemugadziri. Kana nzvimbo yekuparadzanisa mafrequency yemutauri yakasarudzwa kuti ive yakaderera uye mutoro wesimba wakanyanya kurema, zviri nyore kupisa mutauri.
3. Kugadziriswa kusina kunaka kwe equalizer
Kugadziriswa kwe equalizer kwakakoshawo. Frequency equalizer yakagadzirirwa kutsiva zvikanganiso zvakasiyana-siyana zvemukati menzwi uye ma frequency asina kuenzana ema speaker, uye inofanira kugadziriswa ne spectrum analyzer chaiyo kana zvimwe zviridzwa. Hunhu hwe transmission frequency mushure me debugging hunofanira kunge hwakati sandara mukati meimwe range. Ma tuner mazhinji asina ruzivo rwekurira anoita kugadzirisa paanenge achida, uye kunyange vanhu vazhinji vanosimudza high frequency uye low frequency zvikamu zve equalizer zvakanyanya, zvichiita chimiro che "V". Kana ma frequency aya akawedzerwa neanopfuura 10dB zvichienzaniswa ne midrange frequency (huwandu hwe adjustment hwe equalizer hunowanzova 12dB), kwete chete kukanganiswa kwe phase kunokonzerwa ne equalizer kuchakanganisa ruzha rwemimhanzi zvakanyanya, asiwo zviri nyore kukonzera treble unit ye audio Burned out, rudzi urwu rwemamiriro ezvinhu ndirowo chikonzero chikuru che burnout speakers.
- Kugadziriswa kwevhoriyamu
Vazhinji vashandisi vanoisa attenuator ye post-stage power amplifier pa -6dB, -10dB, kureva kuti, 70%--80% ye volume knob, kana kutoti nzvimbo yakajairika, uye vanowedzera input ye front stage kuti vawane volume yakakodzera. Zvinofungidzirwa kuti speaker yakachengeteka kana paine margin mu power amplifier. Kutaura zvazviri, izvi hazvina kunakawo. Attenuation knob ye power amplifier inoderedza input signal. Kana input ye power amplifier ikaderedzwa ne 6dB, zvinoreva kuti kuchengetedza volume yakafanana, front stage inofanira kuburitsa 6dB yakawanda, voltage inofanira kupetwa kaviri, uye headroom yepamusoro ye input, ichagurwa nepakati. Panguva ino, kana paine chiratidzo chikuru kamwe kamwe, output ichawedzerwa 6dB nekukurumidza, uye waveform yakachekwa ichaonekwa. Kunyangwe power amplifier isina overload, input i clipping waveform, treble component inorema zvakanyanya, kwete treble chete yakakanganiswa, asi tweeter inogonawo kutsva
Patinoshandisa maikorofoni, kana maikorofoni iri pedyo zvakanyanya nespika kana yakatarisana nespika, uye vhoriyamu yepower amplifier yakabatidzwa zvine ruzha, zviri nyore kugadzira mhinduro yeruzha rwepamusoro-soro uye kukonzera kurira, izvo zvinoita kuti tweeter ipere. Nekuti masaini mazhinji epakati nepakati neetreble anotumirwa kubva ku treble unit mushure mekupfuura nepakati pe frequency divider, chiratidzo ichi chine simba guru chinopfuura nepakati pe treble unit ne coil yakatetepa, ichigadzira instantaneous current yakakura, zvichikonzera kupisa kwakanyanya pakarepo, uye ichivhuvhuta voice coil wire, tweeter yakatyoka mushure mekuridza mhere "woo".
Nzira chaiyo ndeyekushandisa maikorofoni isiri pedyo kana kutarisana neyuniti yespika, uye simba reamplifier rinofanira kuwedzerwa zvishoma nezvishoma kubva padiki kusvika pakuru.gudzanzwizvichakuvara kana vhoriyamu yakakwira zvakanyanya, asi mukana mukuru ndewekuti simba re amplifier yesimba harina kukwana uye loudspeaker yakabatidzwa zvakasimba, zvekuti kubuda kwe amplifier yesimba hakusi kwemafungu esine akajairika, asi chiratidzo chine zvimwe zvinhu zvinokanganisa, izvo zvinopisa speaker.
