成果简介	NOVELTY - The device has a compensation signal calculation unit (7) that is configured to calculate the delay of the sound signal depending on the temperature, humidity and pressure parameters received from a meteorological unit (8), as well as to calculate the compensation signal based on the amplitude-phase and frequency characteristics. The compensation signal calculation unit is connected to a digital signal processor (9). The digital signal processor is configured to enter the calculated compensation signal into the sound signal, correct the amplitude-frequency characteristic and the amplitude of the received signal and generate the calculated delay of the received signal. An output of the digital signal processor is connected to an amplifier (10) whose output is configured to be connected to a sound source (11). USE - Device for converting and amplifying sound operating as portion of distributed centralized system or audio signal for sound distribution in public places. ADVANTAGE - The increase in the quality of sound obtained from a distributed public address system is realized. DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram illustrating the device for converting and amplifying an audio signal for sound reinforcement in public places. 7Compensation signal calculation unit 8Meteorological unit 9Digital signal processor 10Amplifier 11Sound source
