Features
1.4 audio/video input, one RF output from 45-550MHz (or 470-860MHz, double side band).
2. Intermediate frequency, twice conversion frequency and with saw filter, low side-band interfere.
3. MCU technique is applied to audio intermediate frequency, video high frequency process and RF
local oscillator, with high stability and accuracy.
4. Integrated circuit is applied to outputs, and each functional circuit of the overall unit adopts SMT technology,
with high security.
5. LED displays frequency, using up and down button to select any preference frequency or channel.
6. Convenient control, all frequency level adjustments on front panel.
7. High efficiency power supply.
8. We can offer different TV system standard according to the customer’s need.
