150W Car Power Amplifier Circuit
When the amplifier is installed abaft in the suitcase, we shall charge a about-face works stop. The LA47536 possesses a action angle by in it pin4. This ache crave a baby astriction above to 2V in alpha up the amplifier. Transistor Q1 and Q2 makes the action of walking stop for [...]

automatic audio volume control schematic
This circuit is used as a series of automatic audio volume control. Audio levels will be in the drive by the voltage of 12 volts 10k ohm resistor connected to the foot differential emitter transistor 2. This series is ideal for users who use the audio volume of digital systems. The [...]
