The circuit that i have designed is a passive one but you can make it an active one by adding a pre amp at the output. Emmanuel s comments on the circuit. Also it uses an integrated circuit op amp that is low many noises or low noise.
Four control inputs provide control of the bass treble balance and volume functions through application of dc voltages from a remote control system or alternatively from four potentiometers which may be biased from a zener regulated supply provided on the.
The 0 01 cap is for high frequency while the 0 22uf cap is for low frequency. Emmanuel s comments on the circuit. This circuit will controll bass treble level tone volume and balance between right channel and left channel input 1 and 2. This small compact stereo amplifier can be used for amplifying music from mobile phones computer usb ipod or any source capable of producing as low as 50 millivolt signal.
