HSFM-2E FM modulator video

HSFM-2E FM modulator videoHSFM-2EHSFM-2E is a multi-functional FM modulator for rural broadcasting our current situation and existing problems in the joint investigation on the basis of many scientific research units to develop the vision product development and production of domestic initiative. It is at this stage Common Cable television transmission system, the towns and villages and village radio and television stations to broadcast the best radio room equipment, it can be widely used in factories, mines, offices, military units, schools and other units of the venue of the sound, expanded tone. Characteristics: FM output level high; implementation of automatic lock, the output frequency stability; Built-in FM output frequency adjustment; Automatic Switcher; FM digital tuner to receive FM; LED digital display; a microphone input, two line inputs; 50 stations frequency memory storage; high-fidelity signal source monitoring; multi-function integrated models, easy to use.
