Akamplifier ya VoIP JWDTE02
JWDTE02 pre-amplifier, izwi kandi nka amplifier y'amashanyarazi ya IP, ikwiriye cyane cyane porogaramu zitandukanye za sisitemu y'amajwi. Ikintu cy'ingenzi ni uko ishyigikira uburyo bwinshi bwo kwinjiza amajwi, harimo imirongo itatu yinjiye, ibiri ya MIC, n'indi imwe ya MP3, kugira ngo ihuze n'ibikenewe bitandukanye byo gusohora amajwi. Ifite imikorere myinshi, kuva kuri -20°C kugeza kuri 60°C n'ubushuhe ≤ 90%, ituma ikora neza mu bidukikije byose. Ifite kandi imiterere idapfa amazi, ikaba irinda IPX6. Uburinzi bwo gushyuha bwubatswemo butuma habaho umutekano. Byongeye kandi, uburyo ikora neza bwo gusubiza inshuro nyinshi no kurinda guhindagurika neza bituma amajwi aba meza. Hamwe na protocole nziza zo gutumanaho no gukoresha neza amafaranga menshi byatumye ikundwa cyane mu bikorwa nko muri za kaminuza, ahantu nyaburanga no ku bibuga by'indege.
1. Interineti imwe ya RJ45, ishyigikira SIP2.0 n'izindi porotoli zijyanye nayo, ifite uburyo bwo kugera kuri Ethernet, cross-segment na cross-route.
2. Ibara ry'umukara rya aluminiyumu yo mu rwego rwo hejuru rya 2U, ryiza kandi ritanga umusaruro.
3. Ibyuma bitanu byinjira mu majwi (mikoro itatu, imirongo ibiri).
4. 100V, 70V isohoka nta gahato n'umusaruro udahinduka wa 4 ~ 16Ω. IMBARAGA: 240-500W
5. Imikorere yo guhindura ingano y'ijwi, buri muyoboro winjizamo ingano y'ijwi idashingiye ku ihinduka.
6. Guhindura amajwi yo hejuru n'ayo hasi ku buryo bwigenga.
7. Ijwi rituje rya MIC1 rifite uburyo bwo guhindura, rishobora guhindurwa kuva kuri 0 kugeza kuri - 30dB.
8. Icyerekezo cya LED gifite ibice bitanu, gihinduka kandi gisobanutse neza.
9. Ifite uburyo bwiza bwo kurinda umuvuduko mugufi w'amashanyarazi no kurinda ubushyuhe burenze urugero.
10. Uburyo bwo gutinza amajwi bwubatswemo, bugabanya neza urusaku rwo hasi rusohoka.
11. hamwe n'uburyo bw'inyongera bwo gusohora amajwi, byoroshye guhuza amplifier ikurikira.
12. Umusaruro ukoresha ibyuma bikoreshwa mu ruzitiro rw'inganda kugira ngo birusheho kuba byiza.
13. Gutangiza ubushyuhe bw'umufana ukonjesha.
14. Birakwiriye cyane gukoreshwa mu birori biciriritse n'ibisanzwe.
| Amaporotokeri ashyigikiwe | SIP (RFC3261, RFC2543) |
| Ingufu z'amashanyarazi | AC 220V + 10% 50-60Hz |
| Ingufu zisohoka | Umusaruro w'amashanyarazi uhoraho wa 70V/100V |
| Ibisubizo byakunze kugaragara | 60Hz - 15kHz (±3dB) |
| Kugoreka kutari umurongo | <0.5% kuri 1kHz, ingufu zisohoka zingana na 1/3 |
| Igipimo cy'urusaku hagati y'ibimenyetso | Umurongo: 85dB, MIC: >72dB |
| Ingano y'impinduka | Ingufu za BASS: 100Hz (± 10dB), TREBLE: 12kHz (± 10dB) |
| Guhindura umusaruro | <3dB kuva ku kimenyetso kidahinduka kugeza ku gukora neza kw'umutwaro |
| Kugenzura imikorere | Igenzura ry'ijwi rya 5*, igenzura rya bass/treble rimwe*, igenzura rya mute rimwe*, igenzura ry'amashanyarazi rimwe* |
| Uburyo bwo gukonjesha | Umuyaga wa DC 12V ufite umwuka ushyushye cyane |
| Uburinzi | Fuse ya AC x8A, umuvuduko muke w'amashanyarazi, ubushyuhe burenze urugero |
Iyi amplifier ya IP ikoreshwa cyane mu gusakaza ahantu hashinzwe ubuyobozi n'aho kohereza amakuru ku mutekano w'abaturage, abapolisi bitwaje intwaro, abashinzwe kuzimya inkongi, ingabo, gari ya moshi, ingabo zirwanira mu kirere, inganda n'ubucukuzi bw'amabuye y'agaciro, amashyamba, peteroli, amashanyarazi, na leta kugira ngo hagerwe ku buryo bwihuse ku icibwa ry'ibibazo no gutumanaho mu buryo butandukanye.
