Circuit Wiring

Wow this is nice intregated amplifier circuit , because this IC can be power output up to 60 Watt . With minimum require voltage 8 V , and maximum voltage 35 V . But this circuit isnt so good to working on car , because output sound is very loud but not smooth. Amplifier so good working on full range , with speaker full range 100W and impedance 8 Ohm.

Below it is schematic :

Minimum Voltage required for this circuit  8 volt and maximum voltage 28 volt . Its can use to amplifier on the electronic devices such us Radio , DVD , MP4 , MP5 , and etc. To amplify the signal sound to audio sound , Maximum output power 2 x 20 Watts with impedance 4 ohm. The circuit is stereo amplifier. You can use the circuit to car amplifier because support to subwoofer speaker. See schematic diagram below :

The schematic above is amplifier based on ic TA7211P or TA7212P , circuit above using OT transformer as a booster amplifier again. The amplifier suitable used on outside / field, because by using a transformer OT is identical to the PA amplifier.
