The audio equipment in the security equipment has increased the use of the audio processor, which not only has the advantages of reducing the peak level, but also improving the average modulation degree, and can also increase the sideband wave power to increase the loudness.
In addition, there are the following four better effects:
1. It can solve the problem of large differences in program level caused by recording, exchange, different program content and the use of different recording and playback equipment, which is difficult to solve when manually adjusting the program level.
2. Create conditions for establishing the volume balance between language programs and music programs.
3. A certain amount of amplification can be performed on the weak signal at the low tide of the program, so that it will not be overwhelmed by the noise component. Usually, the level value of the treble component in the program is low, and it can be improved by an appropriate amount after processing. The treble component not only determines the clarity of the program, but also has a complex psychological and physiological relationship with the loudness. increase, so that the listeners feel that the loudness has also increased.
4. Stereo broadcasting, its coverage radius is about half of that of mono broadcasting at the same power level. After using the audio processor, due to the increase of sideband wave power, there are places where the received carrier field strength is slightly lower than the requirement. A higher quality signal may be received, extending coverage.
The average power of the processed music is 8.2dB higher than that of the pre-processed music. Comparing it with the ordinary limited amplifier with a compression of 15dB, the obtained value is 5.9dB, which is actually equal to 4 times the increase of the transmitting power. Using an audio processor to increase the coverage can save a lot of power, equipment investment and maintenance costs compared to other methods, and it is a very economical and feasible method. Of course, the audio processor should compress the content of the program in an appropriate amount. Excessive compression will damage the content of the program, affect the artistic effect of the music, and make the stereo broadcast lose its due characteristics.
