Bengifuna ukuziqoqa izikhulumi zokugcina empilweni. Qoqa futhi wehlise umoya. Futhi ngazibekela umgomo oyinhloko - hhayi intela, ungazi ukuthi ungazi, ngakho-ke ngasebenzisa kuphela izixazululo ezinokwethenjelwa, ezifakazelwe, ngingazami ukujuluka phezu kwekhanda.
Kwenzekani phambi kwakho esithombeni:
Amandla
Iningi lazo zonke lithinta umsindo wokungenzi kwe-wire, hhayi i-amplifier ngokuya ngama-audiophile. Lokhu ngokuqinisekile kunamandla. Futhi ngaqala ukuhlangana izikhulumi kusuka ekufuneni izikhulumi "ezihamba phambili". Imho. Ngikhethe isikhathi eside, ngilalele futhi ngimiswe ezikhuluma ngezikhulumi ze-Broadband Visaton B200.
Lesi sikhulumi esisodwa sidlala lonke uhla kusuka ku-57 kuye ku-18,000 Hz. (Kusuka ku-40 hz ngesihlungi). Okungukuthi, kusebenza kathathu. Futhi lokhu kuhle, ngoba ngeke ngidinge ukucabanga nge-crossover kanye nokuxhumana kwezikhulumi. Izinketho zokuqongelela. Lesi sikhulumi sinezikhathi eziyi-10 izikhathi ezi-10 zokuzwela kunezikhathi ze-S90 Soviet. Lokho wukuthi, wanele 3 W amandla okumemeza ikholomu ye-S90 s90 s90 kuma-Watts angama-30. Mayelana nomsindo engingeke awuthumele wona, ngoba konke kuyinto ebekiwe, kodwa ngathatha amanzi abilayo.
Akwenzeki yonke indawo kahle. Ukuwina koyedwa, silahlekelwa kwelinye. I-pair yalezo zikhulumi idinga ibhokisi lelitha eli-150 lomsebenzi ogcwele. Lokhu kuyivolumu yokugeza.
-Zwayo
Lapho usufunde izinkundla ezahlukahlukene mayelana nezingozi zamabhodi omsindo ahlanganisiwe, ngathenga imali entsha yomsindo. Kwakungumsindo we-X-FI we-Creative X-FI, ngiyaxolisa ngemali. Wafika ekhaya, wavula, wamangala futhi wacasuka. Umsindo ovusiwe futhi uwonke ubembi kakhulu kunomsindo owakhelwe ngaphakathi. Ngosuku olulandelayo, ngathola ukuthi yonke imisebenzi 'yokuthuthuka' komsindo, okuyizilungiselelo zamakhadi omsindo, phula kuphela umsindo. Khubaza ngokushesha. Ukuhlola uhlelo lwe-Rmaa nakho akukhombisanga ukuphakama kwaleli khadi lomsindo ngaphezulu kwalo okwakhelwe ngaphakathi.
Isihloko ngesihloko: Izinto ezintsha ezindala zokuphila: ukuhlobisa izihlalo, ikhabethe nezingubo
Uyokwazi ukuthi ngijabule kangakanani lapho ngihlangana nohlelo lwe-RMAA. Ngiqale ukukala lolu hlelo konke okusemandleni futhi kungalinganiswa. Isibonelo, ukuhlanekezela okwenziwe ngomsindo ngu-Chinese Power Transformer. Noma ukuhlanekezela okwenziwe ngomsindo we-kagesi kagesi.
Futhi futhi, ukubheka okungenangqondo, ngashisa inkokhelo yomsindo. Ngemuva kwalokho ngathenga imali ebizayo yomsindo ka-Esi Juli @, kepha bekungekho nomphumela obonakalayo kuye.
Isiphetho: Imisindo eyakhelwe ngaphakathi yinhle.
Ama-Electronics
Njenge-amplifier, ngikhethe i-LM3888 Chip. Le yindlela eyinkimbinkimbi kunazo zonke yokuthola ikhwalithi ye-hi-fi edolweni. I-chip kanye ne-amplifier uqobo ngihlole uhlelo lwe-RMAA. Le chip iyi-oda yobukhulu obungcono kune-hi-fi ejwayelekile edinga. Ukuhlanekezela kwakhe izikhathi eziyi-100 kungaphansi kwalokho kuzwa indlebe yami.
Abanye bazothukuthela ukuthi ama-amplifiers amahle ashibhile kune- $ 10,000 akekho! Kepha ukhuluma ngedivaysi enamakhulu ezici namabhulokhi. Ngikhuluma nge-block kuphela emane yandisa amandla wamanje amahlandla ayi-100.
Abanye abalandeli abasuselwa kule chip bakha ama-amplififiers nge-0.0002% ukuhlanekezela.
Ngiqoqe inguqulo yokuqala ye-amplifier ebhodini lesekethe. Lokhu kwenze kwaba nokwenzeka ukuthuthukisa ukukhulisa kabusha (ukufaka izinto, ukuguqula uhlelo, izintambo kanye nokulinganisa konke ku-RMAA). Ngemuva kwalokho ngenza ibhodi lesekethe elishicilelwe elishicilelwe (lout), kepha ikhwalithi ye-amplifier ayikashintshile kulokhu, i-RMAA iyahlolwa.
Isiphetho: Imali ekhokhwayo ayilungile.
Njenge-radiator, ngasebenzisa okupholile ku-processor (ngaphandle komlandeli). I-amplifier izosebenza ngaphandle kwama-watts angaphezu kuka-5. Emandleni amakhulu, isikhulumi siqala ngobuhlungu, futhi izindlebe zibuhlungu. Kepha noma ngabe i-amplifier igcwala ngokweqile, bekungeke kwephulwe. Isifunda sokuvikela ngokweqile esakhelwe kwi-amplifier kumane nje sacima. Kepha lokhu akukaze kwenzeke.
Isihloko ngesihloko: Ungayisusa Kanjani Imicu efenisha ekhaya
I-Chema, ibhodi yesekethe. Ngiyaxolisa, ikhwalithi engcono kakhulu ayigcinwanga.
Ukuqoqana
Njengendaba yecala, ngakhetha chipboard engu-16 mm. I-MDF ibiza amahlandla ama-4 abiza kakhulu, kepha awunangqondo. Kungenzeka ukuthi uthathe i-chipboard enkulu, kepha khona-ke ikholamu lizoba kubhokisi lokungenayo. I-chipboard yomthengisi ibona leli shidi ezingxenyeni zosayizi ofiselekayo. Futhi lokhu kuhle, ngoba nginezinkinga ngezandla ezivuhlayo, kahle, akunakwenzeka ukusika ibhokisi elibushelelezi.
Nginqume ukwenza ikholomu ukwenza izikhulumi ezingeni lezindlebe. Ukwandisa ubulukhuni bomzimba, ama-struts afakiwe kukholamu. Imininingwane ifakwa nge-glue "izinzipho eziwuketshezi" bese ubeka ukudonsa.
Isikhulumi angizange ngivale igridi noma indwangu. I-Grille ibukeka kanjalo ngesiShayina. Futhi indwangu yonyathelisa umsindo.
Kwavela ibhokisi elinjalo. Umthetho wami awukhokhiswa intela! Ngakho-ke, ngakhetha ukwakheka okulula kakhulu, kepha hhayi ukufana. Ukufana kuyadina.
Ngaphezu kwalokho, ikholomu yayidingeka ukupenda noma ukufaka ifilimu. Ngikhethe ifilimu, ngoba nginokuhlangenwe nakho okuningi kokuzilolonga futhi kuvela kahle. Ngikhipha ibala elincanyana lisuka ensingoni elahlekile, ukusika imiphetho. Ngithatha i-rag, umbusi, i-iron ne-glue.
Kepha ngaphambi kokunamathisela noma ukupenda, wonke ama-slots, izimbobo ezivela kwizikulufo kanye nemiphetho engalashwa yamapuleti amboza ungqimba lwe-putty.
Sinamathisela ukukhahlela ezindongeni zezindlu. Esikhundleni sebhodi le-synthet, kungenzeka ukuthi lithathe inkampani, yenzelwe ngqo izikhulumi, impahla edangele. Kepha futhi, ukuhlolwa kwe-RMMA kusho ukuthi akukho mehluko, kepha ngavilapha uku-oda amalitha angama-70 wezinto ezibonakalayo.
Kungani kunesigaba sesigaba kwikholamu? Ngoba lesi sikhulumi senzelwe ibhokisi elivaliwe elinezinto ezidangele.
Amakholomu azimele ngokuphelele. Ikholomu ngayinye ine-amplifier yayo kanye nokunikezwa kwayo kwamandla.
Isihloko ngesihloko: Vula i-top crochet ephezulu kusuka kuma-motifs Wabasaqalayo ngezithombe nevidiyo
Ngisebenzise isixhumi se- "jack 6.25 mm" sokuxhuma umsindo, ngethemba lokuthi izokwethembeka ngaphezu kwezinye izixhumi. Kepha kwavela ukuthi konke kukhulu, konke kuyaphuka. Kepha kunjalo, esixhumi esinjalo ungaxhuma isiginci sikagesi ngaphandle kwama-adaptha.
Kepha umbono wokusebenzisa izixhumi zamandla, zombili ekhompyutheni, uphumelele kakhulu. Lapho bonke abaqaphi, amakhompyutha, ama-projektha, amaphrinta, njalo izintambo zamamitha angama-5 zikhishwe ekhaya lakho - into ayinakufinyeleleka epulazini!

P.S. Ekuqaleni ngangicabanga ukuthi ingaphansi elingaphansi lingeze, kungaba yinto efana nohlelo lwe-2-strip. Kepha izikhulumi ezifanayo zangiphendukela kwanele. Amabhodlela awazwakali kakhulu, kepha muhle kakhulu.
