Surround Amplifier Circuit with TDA7053

Perhaps the surround amplifier circuit below is an interesting circuit is made. For, making easy just by using the IC and electrolytic capacitor added 1 , we already can hear the strains of music with sound ( Front Left ,Right and surround Right , Left. In addition to listening to music , this amplifier is also very suitable for gamers who want good sound quality. Minimum voltage requred 9 volts and maximum of 15 volts. Power Output of each speaker 10 Watt with 4 ohm impedance.

Good Quality Sound Amplifier Circuit

This amplifier circuit has a pretty good quality. Of course the sound quality, although this one amplifier does not have a large output power but in terms of soft and loud voice that this amplifier can be unreliable. With a single IC capitalize MPC576H and several other supporting components you have to make this amplifier circuit. Voltage at least 9 Volt and 24 Volt Max. Output Power 3.5 Watts with 8 Ohm impedance.
