Stereo Tone Control circuit diagram LM1036
This is a stereo audio tone control circuit which build based on IC LM1036. This circuit will controll bass/treble level tone, volume and balance between right channel and left channel (input 1 and 2 ). You may use this circuit for stereo applications such as car radio, TV and audio systems, mp3 player, dvd player, ipod and more. An additional control input allows loudness compensation to be simply effected. The circuit should be works with supply voltage 9V to 15V DC.Tone control features:
* Wide supply voltage range, 9V to 16V
* Large volume control range, 75 dB typical
* Tone control, ±15 dB typical
* Channel separation, 75 dB typical
* Low distortion, 0.06% typical for an input level of 0.3 Vrms
* High signal to noise, 80 dB typical for an input level of 0.3 Vrms

2x22W Stereo Power Amplifier circuit based TDA1554
This is is a stereo power amplifier schema works up to 22W on each channel. It will be 2x22W output. A few externel components required to support the main component of TDA1554. Heatsink on the power IC is a must to prevent overheating on the power IC. The chip should run cool enough to touch with the proper heatsink installed.
Operated at 12 Volts and at about 5 Amps at full volume. Lower volumes use less current, and therefore produce less heat. Printed schema board is preferred, but universal solder or perf board will do. Keep lead length short.
