WSJ1016B is a 16-channel frequency-separated 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
16-channel audio and video input, with one RF channel outputting sixteen channels with frequency spacing.
High-frequency modulation is adopted, resulting in minimal out-of-band interference.
The audio and video use MCU phase-locked technology, ensuring high frequency stability and accuracy.
All functional circuits of the entire machine adopt chip-like craftsmanship, providing high overall reliability.
Easy to operate; volume level and video modulation depth can be adjusted on the front panel.
