This Thor Broadcast F-4A-XLR-B-PHP-TxRx 4 Bi-Directional XLR Analog Audio With 48V DC Phantom Power is a professional stage transmission equipment developed by our company, with independent intellectual property rights. Absorbing the advantages of similar products at home and abroad, combined with the actual demand of the market, we launched the broadcast XLR balanced audio fiber optic converter, using FPGA, digital code, and clock recovery technology, with high integration, high stability, and high intelligent noise reduction system. To ensure the reliability, consistency, and stability of the equipment for soft rising or falling ramp waves and simulated squelch with a 100dB signal-to-noise ratio (SNR) without popping sound operation. Combined with the application requirements of the scenario, the product is more flexible and practical.

CWDM technology realizes multi-channel signal transmission,on the basis of it, video, data, network, telephone, contact closure, and other functions can be added according to different application scenarios. Plug and pull board card design, support 4U chassis, convenient for users to manage uniformly, maintenance, The diversity of optical ports support 1*9 fiber module, SFP fiber module (plug and pull fiber module design, can be replaced according to the actual requirements of the site, it is simple to operate, plug and play), this series of products have been in commercial operation for a long time. Practice has proved that the product has stable performance, simple installation, easy maintenance, and it is suitable for large-scale commercial operation.
