Single Chip Amplifier + Tone Control This ambit is based on the National Semiconductor LM3876. This accessory is able of carrying as abundant as 56W of connected boilerplate ability into an eight ohm amount with 0.1% THD from 20Hz to 20Khz. Be abiding to accommodate an able calefaction bore for the package. Use log pots [...]
A photo of the Revision-A preamp is shown below. You’ll see that there are two dual opamps, but the schematic only shows one. This is the main part of the Rev-A update – the output section now has gain (which is easily selected), and a better buffered low output impedance. The remainder of the circuit [...]
2 Way Cross-Over 3500 Hz (bass and treble) This is 2 way cross-over for your speaker system. This circuit will handle 2 speaker that are woofer (low frequency) an tweeter (high frequency). The result will shown as below picture: Here the schematic diagram of the circuit:
LM1036 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 [...]
