Problems solved by technology

[0003] Most of the existing FM transmitters are equipped with one channel, that is, there is only one input port, and one chassis can only transmit and transmit audio information of one channel, which is inefficient
For audio information that needs to send multiple channels, several chassis need to work together, which consumes too much energy

Abstract

The invention provides an eight-channel frequency modulation transmitting all-in-one machine, which comprises a case, and is characterized in that eight input ports, a decoding unit, an eight-channeladjusting plate, a synthesizer, a power amplifier, a power supply, a switch, a video interface and an antenna interface are arranged in the case; the decoding unit comprises an audio decoder group andan audio-video decoder; the input ports are connected with the audio decoder group or the audio-video decoder, the audio decoder group or the audio-video decoder is respectively connected with the eight-channel adjusting plate, the eight-channel adjusting plate integrates the eight-channel FM modulator and the eight-path radio frequency device; the eight-channel adjusting plate is externally connected with the synthesizer; the synthesizer is connected with the power amplifier; the power amplifier is connected with the antenna interface; and the audio and video decoder decodes the audio part,and the video part is directly output to the video interface. The eight-channel frequency modulation transmitting all-in-one machine is reasonable in structural design, and compared with a traditionalfrequency modulation transmitter, the all-in-one machine integrates eight channels in one case, so that audio / audio / video information of the eight channels can be received, processed and sent at thesame time, energy consumption is reduced, energy is saved, and the environment is protected.

Description

technical field [0001] The invention relates to the technical field of frequency modulation transmission, in particular to an eight-way frequency modulation transmission integrated machine. Background technique [0002] The FM transmitter modulates the audio signal and the high-frequency carrier into a FM wave, so that the frequency of the high-frequency carrier changes with the audio signal, and then amplifies the generated high-frequency signal, power amplifier and a series of impedance matching, so that the signal output to the antenna, the sending device. [0003] Most of the existing FM transmitters are configured with one channel, that is, there is only one input port, and one chassis can only transmit and propagate audio information of one channel, which is inefficient. For the audio information that needs to send multiple channels, several chassis need to work together, which consumes too much energy. Contents of the invention [0004] The object of the present i...
