Its main characteristics are as follows: 1. Built- in 5-channel power amplifier that can adapt to AC-3/DTS and stereo music playback. 110W main channel and central surround sound. 2. Mix of AC-3/DTS, VCD and DVD. AUX input interface and super bass/stereo output interface. 3. 6-channel volume control and independent level control. 7-stage electronic balance. 4. Bass enhancer system, cyber logic, hi- fi playback. 5. One button for movie, music and karaoke. 6. Intelligent voice navigation. 7. Multiple electronic balance modes that adapt to different music styles. 8. Automatic spectrum analysis and compensation, automatic signal compensation. 9. Profile surround sound. Situation effect processing for AC-3/DTS effect. 10. Multiple spectrum display modes. 11. Complete karaoke function including microphone independent volume control, overall volume control, and voice compensation, delay and echo adjustment. 12. Karaoke wide sound field function. 13. Touch control function. 14. Intelligent protection upon overcurrent and over voltage. Chapter Two Operating Principle Section One Structure AV230 (RU) mainly consists of the following seven parts: I. Volume Board: select input of signal source, cyber logic, and bass enhancer control. II. Signal Processing Board: karaoke signal processing and 5.1-channel signal amplification. III. CPU Board: overall control, frequency point gating, automatic search circuit. IV. Control Panel: VFD display, touch selection and backlight display. V. Voice Board: intelligent voice navigation system, operating mode indicated by voice VI. Power Panel and Protection Circuit: provide operating voltage required by element circuits and execute overall protection. VII. Power Amplifier Board: power amplification of 5.1 channel signal or analog signal. Section Two Volume Board AV230(RU) has four input
