I-VoIP Amplifier JWDTE02
I-JWDTE02 pre-amplifier, eyaziwa nangokuthi i-IP power amplifier, ifaneleka kakhulu ezinhlelweni ezahlukene zesistimu yomsindo. Isici sayo esiyinhloko ukusekela kwayo ukufakwa kwesignali okuningi, okuhlanganisa ukufakwa kwemigqa emithathu, ukufakwa kwe-MIC okubili, kanye nokufakwa kwe-MP3 okukodwa, ukuze kuhlangatshezwane nezidingo zomthombo womsindo ezahlukahlukene. Ububanzi bayo bokusebenza, kusukela ku--20°C kuya ku-60°C kanye nomswakama ≤ 90%, kuqinisekisa ukusebenza okuzinzile kuzo zonke izindawo. Iphinde ibe nomklamo ongangeni manzi, ofinyelela ukuvikelwa kwe-IPX6. Ukuvikelwa kokushisa okwakhelwe ngaphakathi kuqinisekisa ukuphepha. Ngaphezu kwalokho, impendulo yayo enamandla yemvamisa kanye nokuvikelwa okuhle kakhulu kokuhlanekezela kuqinisekisa umsindo wekhwalithi ephezulu. Ngezinqubo zokuxhumana ezikhethiwe kanye nokusebenza kahle kwezindleko eziphezulu kuye kwayitholela udumo olukhulu ezinhlelweni ezifana namakhampasi, izindawo ezinhle kanye nezikhumulo zezindiza.
1. Isixhumi esibonakalayo se-RJ45 esisodwa, esisekela i-SIP2.0 kanye nezinye izinqubo ezihlobene, esinokufinyelela okuqondile ku-Ethernet, ingxenye ewelanayo kanye nendlela ewelanayo.
2. Iphaneli elimnyama elinobuhlalu obuphezulu be-aluminium 2U, elihle futhi elinomusa.
3. Okufakwayo kwesignali okuhlanu (amamakrofoni amathathu, imigqa emibili).
4. Ukukhishwa kwe-voltage okungaguquki okungu-100V, 70V kanye nokukhishwa kokumelana okungaguquki okungu-4~16Ω. AMANDLA: 240-500W
5. Umsebenzi wokuguqulwa kwevolumu ephelele, ukulungiswa kwevolumu ngayinye yesiteshi sokufaka okuzimele.
6. Ukulungiswa okuzimele kwamathoni aphezulu naphansi.
7. Umsindo othule we-MIC1 ozenzakalelayo oneswishi yokulungisa, ububanzi obulungisekayo: 0 kuya ku-30dB.
8. Isibonisi sezinga le-LED samayunithi amahlanu, esiguquguqukayo futhi esicacile.
9. Ngokuvikelwa okuphelele kwe-short circuit kanye nomsebenzi wokuvikela amazinga okushisa aphezulu.
10. Isekethe yokuguqula isignali eyakhelwe ngaphakathi, inciphisa kangcono umsindo ophansi wokukhipha.
11. nge-interface yokukhipha umsindo esekelayo, kulula ukuxhuma i-amplifier elandelayo.
12. Okukhiphayo kusebenzisa iziphesheli zohlobo locingo lwezimboni ukuze kuxhunywe ngokwethembeka.
13. Ukuqala kokulawula izinga lokushisa kwefeni yokupholisa.
14. Ifaneleka kakhulu ukusetshenziswa kokusakaza kwemicimbi yomphakathi ephakathi nendawo nencane.

| Ukuvikelwa | I-AC fuse x8A, i-load short circuit, izinga lokushisa elingaphezu kwamandla |
Lesi sikhulisi se-IP sisetshenziswa kabanzi ekusakazeni izindawo zokulawula kanye nezinhlelo zokuthumela zokuphepha komphakathi, amaphoyisa ahlomile, ukuvikelwa komlilo, amabutho, izitimela, ukuzivikela emoyeni, amabhizinisi ezimboni kanye nezezimayini, amahlathi, uphethiloli, ugesi, kanye nohulumeni ukuze kufezwe impendulo esheshayo ekulahleni okuphuthumayo kanye nokuxhumana okuhlanganisiwe kwezindlela eziningi zokuxhumana.
