Power Supply: Provide required working voltage to element circuits. II. Signal Processing (including input, cyber logic, bass enhancer and volume control circuit.) Selecting input signal sources, cyber logic, bass enhancer, small signal preamplification and independent electronic volume control over channels. "Bass enhancer" function is added to AV210T (RU). III. CPU Control Being the control and processing center of the device, it consists of CPU, panel control and software recognition circuit, providing users with a "man-machine conversation" environment, so as to fulfill device control and frequency spectrum display. IV. Microphone Circuit It consists of preamplifier circuit and echo processing circuit. V. Power Amplifying and Circuit Protecting Conduct post power amplification for small signal. Meanwhile, conduct automatic protection for power amplifier circuit and sound box. . Tuning Mainly realize the reception and transition of radio signal. . The principle figure of entire device is as follows: SW
