WSJ-M16 is a 16-channel modular modulator developed by WSJE Company. It can convert 16 audio and video signals into a single RF signal 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
The device supports 16 AV input channels and 1 RF output channel (suitable for global use).
The modulation circuit adopts mainstream modulation chips combined with microcontroller control, ensuring stability and reliability.
The modulation circuits for each channel are completely independent, offering great flexibility and convenience in channel configuration.
It has a large power redundancy, allowing for continuous and stable operation throughout the year.
It can work with input AV signals and can be installed and constructed by non-professional personnel.
The multi-channel modulator is integrated for installation, with a compact structure and no need for a dedicated machine room.
