Two-mugero amplifiers: zvinokosha parameters, marudzi uye kupatsanura
In stereos siyana redhiyo gudzazwi yakavakwa kupinda mudziyo. Zvisinei, zvinokosha kushandisa hunyambiri-mugero kuburikidza yepamusoro simba vakurukuri uye kuisa kwazvo inzwi amplifiers. Amplifiers zvinogona chokuita zvose nemasipika uye vanhuwo migero vachishandisa bhiriji. Ivo vanotsigira yakaderera-impedance mutoro. The chikuru anobatsirwei kugona kuponesa kuchigadzirisa mubatanidzwa.
Paakaisa kuti redhiyo gudzazwi hapasi mutsindo unhu hwakanaka. Unogona kugadzirisa dambudziko iri kuburikidza nekuisa ruzha processor.
Parameters vaviri-mugero amplifiers
Power - nechiidzo inokosha nokuda gudzazwi. Zvinokosha mhando mbiri: chezita (RMS) uye kunonyanyisa (PMPO). Kana kutenga mapepa zvinogona kuverengwa pamusoro yavose sezvavakatarirwa simba. On the chigadzirwa zvakanyorwa pamusoro multi-nzira, iyo inoratidza kunonyanyisa simba nevakawanda makwara. Kana kutenga chinhu gudzazwi, tarisa. Kuvapo rugwaro, izvo zvairatidza kuti fekitari metering mudziyo simba
Two-mugero amplifiers zvinosanganisira pakuvara Crossover, izvo zvinoita kuti tikwanise kudimburira pasi, kusiya treble. Tichishandisa parameter ichi, zvinokwanisika kuti kuchinja mashoko cutoff kakawanda zviri zvishoma uye tinobereka kurira amplification mumwe chete gwara. Bass kugadzirisa bhatani - yaibatsira chinokosha, kunyanya kana iwe kubatanidza subwoofer: zvinokwanisika kuti zvishoma nezvishoma kuwedzera bass revarombo.
Bridged kubatana kunoita kuwedzera nhamba simba. By yakadaro nzira inoshandiswa kubatanidza mukuru-simba subwoofers.
Two-mugero amplifiers nepokuongorora connector kuti unobva munhu Linear waya. Linear waya takura kugamuchirwa anonongedzera neezvitendero redhiyo. Overheating wegadziriro amplifiers vakatasva feni.
Kusarudza makaseti amplifiers, kuteerera mugadziri wacho kutengeserana, kupa kupfuura vaya nekusimba pachavo zvinobatsira divi.
The Mhando chikuru
Two-mugero amplifiers ndiwo: chubhu, transistor, dzemasanganiswa, digitaalinen uye Tripathi. In wokutanga mhando anoshandisa wemagetsi Vacuum chubhu, uye inzwi cascading wakabudiswa. Transistor amplifiers zvakawanda simba uye tanga inzwi kwazvo. Digital makaseti amplifiers vari Integrated nematunhu, vane yakakwirira kushanda zvakanaka uye wakagadzikana nani unhu.
Vakaberekwa amplifiers ine zvemagetsi sepombi, semiconductors uye Integrated mumatunhu, tichibatanidza zvakanakira yapfuura kwemarudzi.
Kupatsanura vaviri-mugero amplifiers
Zvichienderana uchishandisa pfungwa, kudoma makirasi inoverengeka maviri mugero amplifiers, izvo dzinokurukurwa pazasi.
Mhando gudzazwi | kirasi | Pfupiso yebhuku | zvakwakanakira |
rambi | A | Simba pasi uye inflated mari. Ivo kukanganisa inzwi, mauri kushanda ndiyo 20%. | Low simba. |
transistor | The | Zvisinei, High kuita coefficient kupera chafariz simba, havana dzakakurumbira. | Two-mugero simba amplifiers vane pasi ruzha pamwero. Compactness, kunyatsoshanda. |
transistor | C | High coefficient maitiro: 75%. | Chinonyanya Zvakanyanya Kunaka Panguva Yepamuviri chingaitwa motokari gudzanzwi michina. |
spachiana | AB | maviri mugero makaseti amplifiers vane yakakwirira coefficient maitiro. Mode - zvenguva pakati modes A uye B. | Zvose zvakanakira nemakirasi A uye B. |
digitaalinen | D | Mano digitaalinen chiratidzo kugadzira. Kushandisa PWM vachisiyanisa inzwi uye wakaiswa maitikiro. Kuvapo nyoro kutotanga regulator uye bass vachisimudza zano. | Small kukura, inzwi chakanaka kuchena kwayo, kumusoro kunyatsoshanda. |
digitaalinen | G, H | The gudzazwi rine kupomba simba nerubatsiro uye inopa digital chiratidzo kugadzira. Zvinonzi vanokosheswa. | Good inzwi hwakanaka. |
Tripathi | T | The goho transistors anobatidzwa panguva pseudorandom maitikiro zvichienderana mazano chiratidzo revarombo. | Kusiyanisa inzwi zano vakawana ultrafine nonlinear kusarurama. High kunyatsoshanda. |
Gudzazwi nokuti Car Audio
Vaviri-mugero gudzazwi nokuda subwoofer akagadzirirwa kuwedzera inzwi uye kunatsiridza bhuku kusvika optimum padanho. Kuti zvakanaka kutenga rakakodzera mudziyo mumotokari, sarudza izvozvo maererano zvechadenga subwoofer.
Two-mugero amplifiers pave inowirirana inzwi chipi redhiyo hurongwa.
