Lub vaj huam sib luag pem hauv ntej
1. Kev hloov kho qib tso zis RF - Lub pob qhov rooj, qib tso zis RF hloov kho tau
2. Kev hloov kho AV piv - Lub pob qhov rooj kho qhov tso zis ntawm A / V piv
3. kev hloov kho qhov ntim - Khawm kom kho qhov loj ntawm qhov tso zis
4. kev hloov kho qhov ci ntsa iab - Knob los kho qhov ci ntsa iab ntawm cov duab tso zis
Lub vaj huam sib luag tom qab
A. Qhov chaw nres nkoj kuaj zis: Qhov chaw nres nkoj kuaj zis video, -20dB
B. RF tso zis: Multiplexer module modulated, tom qab sib tov cov zis RF
C. Kev tswj hwm RF tso zis: Knob, qib tso zis RF hloov kho tau
D. Cov zis hluav taws xob cascade
Kev sib txuas ntawm ntau lub modulators, koj tuaj yeem tso zis tawm ntawm qhov ntawd mus rau lwm lub zog modulator kom txo qhov chaw siv hluav taws xob; ceev faj tsis txhob tso zis ntau tshaj 5 kom tsis txhob muaj tam sim no ntau dhau.
E. Lub zog fais fab: AC 220V 50Hz / 110V 60Hz
F. RF tswv yim
G. Cov tswv yim HDMI
