Incazelo Yomkhiqizo
1. ISINGENISO
I-AH2401H iyi-modulator yesiteshi esingaguquki esingu-24. Izoba nezimpawu zomsindo nevidiyo ezingafika ku-24 emgwaqweni oneziteshi ze-TV ezingu-24 zezibonakaliso ze-RF. Lo mkhiqizo usetshenziswa kabanzi emahhotela, ezibhedlela, ezikoleni, ekufundiseni nge-elekthronikhi, emafektri, ekuqapheni ezokuphepha, kumavidiyo e-VOD uma kudingeka nakwezinye izindawo zokuzijabulisa, ikakhulukazi ekuguqulweni kwe-analog ye-TV yedijithali, kanye nohlelo lokuqapha oluphakathi.
2. IZICI
- Izinzile futhi ithembekile
- I-AH2401H yesiteshi ngasinye izimele ngokuphelele, ukuguquguquka kokucushwa kwesiteshi
- Kusetshenziswa indlela ye-MCU ye-oscillator yendawo kanye ne-RF, ukuzinza kwemvamisa kanye nokunemba okuphezulu.
- Kusetshenziswa umsebenzi wama-chip esekethe ahlanganisiwe ngamunye, ukuthembeka okuphezulu konke
- Ukunikezwa kwamandla ekhwalithi ephezulu, ukuzinza kwamahora angu-7x24

Iphaneli engaphambili
1. Ukulungiswa kwezinga lokukhipha le-RF—I-Knob, izinga lokukhipha le-RF elilungisekayo
2. Ukulungiswa kwesilinganiso se-AV—I-Knob ilungisa umphumela wesilinganiso se-A / V
3. ukulungiswa kwevolumu—Inkinobho yokulungisa usayizi wevolumu yokukhipha
4. ukulungiswa kokukhanya—Inkinobho yokulungisa ukukhanya kwesithombe esiphumayo
Iphaneli yangemuva
A. Imbobo yokuhlola okukhiphayo: Imbobo yokuhlola okukhiphayo kwevidiyo, -20dB
B. Umphumela we-RF: Imojula ye-Multiplexer ilungisiwe, ngemva kokuxuba umphumela we-RF
C. Ukulawulwa kokukhipha kwe-RF: I-Knob, izinga lokukhipha le-RF elilungisekayo
D. Ukukhishwa kwamandla e-cascade
Ukubeka ama-modulators amaningi endaweni eyodwa, ungakhipha amandla avela kuwo uye kwenye i-modulator ukuze unciphise ukusebenza kwe-outlet kagesi; qaphela ukuthi ungadluli ama-5 ukuze ugweme ugesi oweqile.
E. Ukufakwa Kwamandla: I-AC 220V 50Hz/110V 60Hz
Okokufaka kwe-F. RF
Okokufaka kwe-G. HDMI
