Audio Surround Decoder Circuit

Image
The circuit schematic drawings Surround Audio Decoder and its components and how to make it ,Audio surround decoder circuit. Surround sound quality is the process of adding the audio source by increasing the number of speakers. This is done by producing audio multitracking in a way that can be issued on a multichannel speaker. Basically surround adopt an existing stereo system. The system uses a two-speaker stereo is right speaker and left speaker. With two speakers will be three-dimensional effect of the sound issued. With the surround, which generated three-dimensional effect was more extensive than in stereo. This is because the surround speakers that use more than two pieces. In addition to supporting the three-dimensional effects, stereo field theory is also noteworthy to organize the arrangement of sounds based on the type of sound produced. Component List : R1-2-7-8-12-13-18-19-20 : 47Kohm R3-4-5-6-21-22-34-35    : 10Kohm R9-10-11-14-15-16-17    : 15Kohm R23-2...

20W Surround audio amplifier with SI 1020G

Have you been use the IC above? if those who have not, IC above is used or applied to the audio power amplifier. IC processing is quite good for use on amplifier home, or room. IC used is SI1020G who have not very high output with only 20W 8 ohm impedance speakers. Supply voltage ranging from 12 volt to 23 volts. Below schematic audio amplifier with IC SI1020G Part List R1 = 100K R2 = 1R C1 = 2u2F C2 = 100uF C3 = 47uF C4 = 10uF C5 = 2200uF C6 = 47uF C7 = 100uF
