16 Channel Fixed Modulator
AV Tv Hotel Cable TV Front System RF Modulator
This model is a space saving and fixed channel modulator system. It consists of 16 individual, vertically mounted, fixed frequency modulators and an efficient switching type power supply module. It is designed for 19” rack mounting.
Each modulator is SAW filtered and is factory set to the desired channel and proper offset. Precise frequency is maintained with PLL circuitry. It offers excellent video performance and high reliability in 4U rack.
