#Modulator
The 16-channel analog modulator is a device we often use when deploying analog TV head-ends. It is easy to operate and easy to maintain. Without affecting the normal viewing of most programs, you only need to replace the module to reply to the problematic channel. Therefore, this device is deeply loved by the majority of small and medium-sized TV operators.
