Minimum Voltage required for this circuit 6 volt and maximum voltage 18 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 , If you want to bring amplfier you can use the 6V rechargeable battery is able to turn it. What use the rechargeable battery ? because with rechargeable battery when battery runs out , you can charge back. See Amplifier schematic with IC BA511 below : Maximum output power 10 Watt with impedance 4 ohm. The circuit is mono amplifier. You can use the circuit to caramplifier because support to low power subwoofer speaker

Description This amplifier can control the volume, balance and tone controls take over. The circuit operates a specially designed IC, LM 1036. The advantage is that few external components are necessary, and that may be, which are cheaper. Used for controlling monopotmeters speaks scheme for itself. S1 loudness can be adjusted. In the position shown, the loudness. Moreover, the IC TDA 1524A Philips same capabilities.
