Ciircuit Power Amplifier TDa7377
Complete
circuit power amplifier 2.1, 3 channel with TDa7377, include in the layout, power supply, bass filter as well as the full PCB layout. Project amplifier ideal for various applications. includes in the board, Power Supply, Preamplifier, bass filter, volume and tone control.
Circuit to use the possibilities of the TDA7377 which has 4 outputs, 2 simple for satellites and the other two bridged for the subwoofer.
The circuit has balance control (P2), if not just need to connect the jumpers. Adjust overall volume (p1), tone control and volume adjustment of the subwoofer.
We have a pre amp (IC1) and bass filter (IC3) with bandwidth of 20-150Hz.
The circuit already has power supply by simply connecting a transformer (AC) simple 9-12 Volts / 3 Amps or more, can also be connected a source (DC) 12-18 volts / 3 amps. Can be a source of computer or notebook, battery car , etc.
This
circuit is not the same as traditional circuit which adopts RC to control Bass/Treble via potentiometers, its Bass circuit adopts Low Pass Filter,doesn’t need additional Treble potentiometer, so it is quite suitable to be used for the power supply refitting for automobile, motorcycle, electric vehicles and multimedia audios, it can help a lot for promoting your sound quality.
