GG-DSB16 8/12/16 Channels fixed channel RF modulator 16 canales de catv modulador
The GG-DSB16 Fixed channel CATV headend RF modulator is a 1RU rack modulator that uploads 4 /8/12/16 channel AV signal input and combined in 1 RF output. The output frequencies should be skipped channel numbers to avoid adjacent channel interfere. Built-in active combiner eliminates unnecessary cabling and potential connection problem and ensures high output level.
All modulators are perfect factory set to desired channels and proper offset.
