+86-185-6525-09081.1 Product Overview
WSJ-M16H is a 16-channel modular modulator developed by WSJE Company. Its function is to convert HDMI signals into RF signals for output. This product is widely used in places such as hotels, factories, hospitals, schools, and enterprises that require a television system.
1.2 Key Features
Supports 16 HDMI inputs and 1 RF output
The modulation circuits for each channel are completely independent, offering highly flexible and convenient channel configuration.
With a large power redundancy, it can operate continuously and stably for long periods.
Relevant debugging for cable TV transmission equipment is completed before leaving the factory, eliminating the need for on-site debugging. Simply input HDMI signals to start working, allowing installation by non-professional personnel.
Multi-channel modulator integrated installation, compact structure, no need for a dedicated machine room.
