+86-185-6525-09081.1 Product Overview
WSJ-M24H is a 24-channel modular modulator developed by WSJE Company. It converts 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 24 HDMI inputs and 1 RF output (suitable for global use).
The modulation circuits for each channel are completely independent, offering highly flexible and convenient channel configuration.
Large power redundancy allows for long-term continuous stable operation.
Relevant debugging for cable TV transmission equipment is completed before shipment, eliminating the need for on-site debugging.
It can operate with input AV signals and can be installed and constructed by non-professional personnel.
Multi-channel modulator is integrated for installation, with a compact structure and no need for a dedicated machine room.
