Isandisi seVoIP JWDTE02
I-JWDTE02 pre-amplifier, eyaziwa ngokuba yi-IP power amplifier, ifaneleke kakhulu kwiintlobo ngeentlobo zeenkqubo zesandi. Uphawu lwayo oluphambili kukuxhasa kwayo ii-signal inputs ezininzi, kubandakanya ii-line inputs ezintathu, ii-MIC inputs ezimbini, kunye ne-MP3 input enye, ukuhlangabezana neemfuno ezahlukeneyo zemithombo yesandi. Uluhlu lwayo olubanzi lokusebenza, ukusuka kwi--20°C ukuya kwi-60°C kunye nomswakama ≤ 90%, luqinisekisa ukusebenza okuzinzileyo kuzo zonke iindawo. Ikwanoyilo olungangeni manzi, olufezekisa ukhuseleko lwe-IPX6. Ukhuseleko lobushushu olwakhelwe ngaphakathi luqinisekisa ukhuseleko. Ngaphezu koko, impendulo yayo enamandla yefrikhwensi kunye nokhuseleko oluhle lokuphambuka luqinisekisa isandi esisemgangathweni ophezulu. Ngeenkqubo zonxibelelwano ezikhethiweyo kunye nokusebenza kakuhle kweendleko eziphezulu kuye kwayinika udumo olukhulu kwizicelo ezifana neekhampasi, iindawo ezintle kunye nezikhululo zeenqwelo moya.
1. I-interface enye ye-RJ45, exhasa i-SIP2.0 kunye nezinye iiprotokholi ezinxulumene nayo, enokufikelela ngqo kwi-Ethernet, i-cross-segment kunye ne-cross-route.
2. Iphaneli emnyama ebhrashiweyo ye-aluminium ye-2U yenqanaba eliphezulu, intle kwaye inesisa.
3. Iigalelo ezintlanu zesignali (iimayikrofoni ezintathu, imigca emibini).
4. I-100V, i-70V ephumayo ngamandla ombane azinzileyo kunye ne-4 ~ 16Ω ephumayo ngamandla okumelana azinzileyo. AMANDLA :240-500W
5. Umsebenzi wokuguqula ivolumu iyonke, itshaneli nganye yokufaka ivolumu ihlengahlengiswa ngokuzimeleyo.
6. Uhlengahlengiso oluzimeleyo lweethoni eziphezulu nezisezantsi.
7. Isandi esingazinzanga se-MIC1 esizenzekelayo esineswitshi yohlengahlengiso, uluhlu oluhlengahlengiswayo: 0 ukuya kwi-30dB.
8. Isibonisi se-LED esinamacandelo amahlanu, sinamandla kwaye sicacile.
9. Ngokhuseleko olupheleleyo lwe-output short circuit kunye nomsebenzi wokukhusela ubushushu obungaphezulu.
10. Isekethe yokuguqula isignali eyakhelwe ngaphakathi, ngcono ukunciphisa ingxolo esezantsi yemveliso.
11. kunye ne-interface ye-audio output encedisayo, kulula ukuyidibanisa i-amplifier elandelayo.
12. Imveliso isebenzisa ii-terminals zohlobo locingo lwemizi-mveliso ukuze kuqhagamshelwe ngokuthembekileyo ngakumbi.
13. Ukuqala kokulawula ubushushu befeni yokupholisa.
14. Ilungele kakhulu ukusetyenziswa kwimiboniso bhanyabhanya yemicimbi yoluntu ephakathi neyincinci.
