Features
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. 19" rack mountable.
