Product Description

Overview:

Our FM and emergency inter-cut host adopts the industry-leading digital software radio technology, with highly integrated products and FM signal modem. At ordinary times, the host receives the FM signal in the air, first amplifies it with low noise, then digitizes the analog signal with digital intermediate frequency processing technology, performs digital frequency selection filtering processing, and then converts it into RF signal and amplifies it again to a certain level for other equipment, such as the FM fiber optic repeater master unit or transmits the signal through the FM antenna to cover the FM broadcast signal in the coverage area. When it is necessary to insert emergency information, set the equipment to "emergency mode" (can be set by hardware button or software), and then input the voice or Mp3 information to be inserted from the FM signal modem port. The equipment will be able to play the emergency signal on all channels.

Product Features:

Advanced technology and high equipment integration. Single equipment includes signal amplification, digital frequency selection, digital frequency shift, FM signal modulation and demodulation and other functions.
There are many channels, including 16 channels, 32 channels, 40 channels and other specifications. You can also customize the whole channel group.
The device is small and only 1.5U in size.
USB port or RJ-45 Port as LAN port to support GUI for local control or lan remote control.
The gain of each channel can be adjusted independently, which can realize the uneven reception of signals from each channel in the air, but the output of each channel can reach the same functional requirements.
Modular structure, easy installation and maintenance.
All nameplates are laser engraved, beautiful, clear and not easy to wear.
