16 channels in 1 analog tv modulators rf modulators with combiner catv headend system

At present, a considerable region have carried out the cable television digitized transformation, however, the way of watching television in some small hotels, lodges and other rented places will face new choices. Therefore, our company launched low-cost integrated multi-channel modulator. Specially designed for MATV or SMATV system. We can easily construct a suitable cable TV front-end for you. It is easily operated or maintained by users.

Features

1 . Modulating circuit modulating chips use with today's mainstream with a single-chip control, stable and reliable.

2 High efficiency SMPS enable stable performance.

3 Each modulation circuit of channels is completely independent; the channel configuration is flexible and convenient

4 Large amount of redundant power supply may be steady year-round job.

5 Related test of cable transmission equipment was completed before delivery, the equipments can be debugged on the site free of charge, and they can work inputting AV signals and can be installed by non-professionals in the construction as well.

6. Multi-channel modulator integrated installation, compact structure, Dedicated room is no need.
