Chowonjezera cha VoIP JWDTE02
JWDTE02 pre-amplifier, yomwe imadziwikanso kuti amplifier ya IP power, ndi yoyenera kwambiri pa ntchito zosiyanasiyana zama audio system. Chinthu chake chachikulu ndikuthandizira ma input angapo a ma signal, kuphatikiza ma input atatu, ma MIC awiri, ndi MP3 imodzi, kuti ikwaniritse zofunikira zosiyanasiyana zama audio. Kugwiritsa ntchito kwake kwakukulu, kuyambira -20°C mpaka 60°C ndi chinyezi ≤ 90%, kumatsimikizira kuti ikugwira ntchito bwino m'malo onse. Ilinso ndi kapangidwe kosalowa madzi, komwe kumateteza IPX6. Chitetezo chotenthetsera chomwe chimamangidwa mkati chimatsimikizira chitetezo. Kuphatikiza apo, kuyankha kwake kwamphamvu pafupipafupi komanso chitetezo chabwino kwambiri chosokoneza chimatsimikizira mawu abwino kwambiri. Ndi njira zolumikizirana zosankhidwa komanso kugwiritsa ntchito bwino ndalama zambiri kwapangitsa kuti ikhale yotchuka kwambiri m'mapulogalamu monga masukulu, malo okongola komanso ma eyapoti.
1. Chida chimodzi cha RJ45, chothandizira SIP2.0 ndi ma protocol ena ofanana, chokhala ndi mwayi wolowera mwachindunji ku Ethernet, gawo lodutsa komanso njira yodutsa.
2. Paneli yakuda ya aluminiyamu yapamwamba kwambiri ya 2U, yokongola komanso yopatsa.
3. Ma input asanu a ma signali (ma maikolofoni atatu, mizere iwiri).
4. Mphamvu yotulutsa mphamvu yamagetsi yokhazikika ya 100V, 70V ndi mphamvu yokhazikika ya 4~16Ω. MPHAMVU: 240-500W
5. Ntchito yonse yosinthira voliyumu, kusintha kulikonse kodziyimira payokha kwa voliyumu yolowera.
6. Kusintha kodziyimira pawokha kwa ma toni apamwamba ndi otsika.
7. MIC1 yokha yopanda phokoso yokhala ndi chosinthira chosinthira, mulingo wosinthika: 0 mpaka - 30dB.
8. Chiwonetsero cha LED cha magawo asanu, chosinthasintha komanso chowonekera bwino.
9. Yokhala ndi chitetezo changwiro chafupikitsa komanso chitetezo chopitirira kutentha.
10. Dongosolo loletsa kugwedezeka kwa chizindikiro chomangidwa mkati, limachepetsa bwino phokoso la pansi lotulutsa.
11. yokhala ndi mawonekedwe othandizira otulutsa mawu, yosavuta kulumikiza amplifier yotsatira.
12. Chotulukacho chimagwiritsa ntchito malo olumikizirana amitundu ya mpanda wa mafakitale kuti chikhale chodalirika kwambiri.
13. Kuyamba kwa fani yozizira poyang'anira kutentha.
14. Yoyenera kwambiri pa zochitika zapakati ndi zazing'ono za anthu onse.
| Ma protocol othandizidwa | SIP (RFC3261, RFC2543) |
| Magetsi | AC 220V +10% 50-60Hz |
| Mphamvu yotulutsa | 70V/100V yotulutsa mphamvu yokhazikika |
| Kuyankha pafupipafupi | 60Hz - 15kHz (±3dB) |
| Kupotoza kosakhala kolunjika | <0.5% pa 1kHz, mphamvu yotulutsa yokwana 1/3 |
| Chiŵerengero cha chizindikiro-ku-phokoso | Mzere: 85dB, MIC: >72dB |
| Kusintha kwa mitundu | BASS: 100Hz (±10dB), TREBLE: 12kHz (±10dB) |
| Kusintha kwa zotuluka | <3dB kuchokera pa ntchito yopanda chizindikiro chokhazikika mpaka ntchito yonse yonyamula katundu |
| Kuwongolera ntchito | Zowongolera voliyumu 5*, 1* bass/treble control, 1* mute control, 1* power supply |
| Njira yozizira | Fani ya DC 12V yokhala ndi mpweya wozizira wokakamizidwa |
| Chitetezo | Fuse ya AC x8A, kufupika kwa katundu, kutentha kwambiri |
Chojambulira cha IP ichi chimagwiritsidwa ntchito kwambiri pofalitsa malo olamulira ndi otumizira chitetezo cha anthu, apolisi okhala ndi zida, chitetezo cha moto, asilikali, sitima, chitetezo cha ndege, mabizinesi amakampani ndi migodi, nkhalango, mafuta, magetsi, ndi boma kuti akwaniritse mwachangu njira zothanirana ndi mavuto azadzidzidzi komanso kulumikizana kophatikizana kwa njira zosiyanasiyana zolumikizirana.
