Catv Modulator

16 in 1 Catv Modulator
 is a space saving, 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.



This 16 channels module type modulator is low cost and high stability, specially designedfor MATV or SMATV system. Professional design with simple installation. It is easily operated or maintained by users.


1. 1 set can install 16 channels. Adjacent channel workable.

2. Individual function keys for each channel, simple operation.

3. High efficiency SMPS enable stable performance.

4. All the figures already pre-set in the factory. No further adjustment to the modulator in case of necessary.

5. Easy setup,Internal fans for cooling modulators

6. Only one RF output. No need combiner

7. Precise frequency control with PLL circuitry

8. Also available in NTSC,all PAL configuration

9. 19” rack mountable.
