Incazelo Yomkhiqizo
1. ISINGENISO
I-AH2401H iyimoduli engu-24 eyimojula yefrikhwensi engaguquki. Izoba amasiginali alalelwayo namavidiyo afinyelela kwangu-24 emgwaqeni oneziteshi ze-TV ezingama-24 amasignali e-RF. Umkhiqizo usetshenziswa kakhulu emahhotela, ezibhedlela, ezikoleni, ekufundiseni nge-elekthronikhi, ezimbonini, ekuqaphelweni kwezokuphepha, ividiyo ye-VOD lapho kudingeka khona nakwezinye izindawo zokuzijabulisa, ikakhulukazi ukuguqulwa kwe-analog ye-TV yedijithali, kanye nohlelo lokuqapha oluphakathi nendawo.
2. IZICI
- Izinzile futhi enokwethenjelwa
- I-AH2401H yesiteshi ngasinye izimele ngokuphelele, ukuguquguquka kokucushwa kwesiteshi
- Imvamisa ephezulu yesithombe kanye nenqubo ye-RF yendawo ye-oscillator ye-MCU isetshenziswa, ukuzinza kwamafrikhwensi kanye nokunemba okuphezulu
- Umsebenzi wesekethe ngayinye ehlanganisiwe isetshenziswa, ukuthembeka okuphelele okuphelele
- Ukunikezwa kwamandla okuphezulu, ukuqina kwamahora angu-7x24

Iphaneli yangaphambili
1. Ukulungiswa kwezinga lokuphuma kwe-RF—I-Knob, izinga lokuphumayo le-RF elilungisekayo
2. Ukulungiswa kwesilinganiso se-AV—I-Knob ilungisa okukhiphayo kwesilinganiso esingu-A/V
3. Ukulungiswa kwevolumu—Inkinobho yokulungisa usayizi wevolumu yokuphumayo
4. ukulungiswa kokukhanya—Inkinobho yokulungisa ukukhanya kwesithombe esiphumayo
Iphaneli elingemuva
A. Imbobo yokuhlola okukhiphayo: Imbobo yokuhlola okukhipha ividiyo,-20dB
B. Ukukhishwa kwe-RF: Imojula ye-Multiplexer ishintshiwe, ngemva kokuxuba okukhiphayo kwe-RF
C. Ukulawulwa kokuphuma kwe-RF: I-Knob, izinga lokuphumayo le-RF elilungisekayo
D. Okukhiphayo kwe-cascade yamandla
I-Superposition yama-modulator amaningi, ungahlehlisa okukhiphayo ukusuka kukho uye kwenye imoduli yamandla ukuze unciphise umsebenzi wokuphuma kwamandla; qaphela ukuthi ungaphumi ngaphezu kuka-5 ukuze ugweme umthamo oweqile.
E. Okokufaka Amandla: AC 220V 50Hz/110V 60Hz
F. RF okokufaka
Okokufaka kwe-G. HDMI
