SK-4860
The SK-4860 4 in 1 Agile TV Modulator is a cost-saving agile modulator, but it's a SKIP CHANNEL modulator. It supports frequency range from 54 to 550MHz or 550 to 860MHz.
Features:
1. Four Video & Audio input, one RF output
2. H.F processed with one-conversion ensures low outband interfere
3. MCU control for frequency control and accuracy
4. Excellent video and audio linearity for superior picture quality
5. LED Display. Four indictor lights for each channel, using UP and DOWN to control output Frequency.
6. PAL, NTSC and SECAM optional
7. Double Side Band Modulator (Skip Channel Modulator)
