KtvK song audio equipment structure:
There are two kinds of stereos: integrated and layered. In integrated audio, all parts of its circuit (including the record player) are in a shell, which is generally used for low-grade audio. In layered stereo, the number of layers is different according to the grade of the machine.
The combo has many layers: record player, CD player, tuner, dual-card recording and playback bracket, tuning controller and main power amplifier. In the low-level stereo, the record player and CD player have one floor each, and others also have one floor. Miniaturization, digitalization, specialization and film and television are the inevitable development trends of home audio.
Digital audio is developed when solving the problem of analog audio noise distortion. After digital audio technology is adopted, the recorded digital signal has clear resolution from sampling frequency to quantization characteristics, and there is no color jitter, so a very clear image can be obtained.
And it can be interchanged with the upper computer, which is incomparable to analog video recording and playback equipment. Digital recording can record the time, name and address into the magnetic tape together, use the micro keyboard to complete the cataloging work, change the number of tracks, and increase the remote control function to automatically search the required tracks, which is convenient to use.
