AV210T (RU) Operating Principle Analysis
Section 1 Overall Structure
The device of AV210T (RU) can be divided into five constituent parts:
I. 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.
ÿ. Tuning
Mainly realize the reception and transition of radio signal.
