This is the schematic diagram of 3 channels audio splitter amplifier
circuit which built using op-amp IC TL084. The 3 channels amplifier
output distribution applies a single TL084.
3 Channels Audio Splitter Amplifier Circuit Diagram
The very first step
is to capacitive coupling having a p. 1.0 ~ electrolytic capacitor. The
entries are railways Vee Y2 or 4.5 V. This enables working with an
individual 9V power source. A voltage gain of 10 (1 M?/100 Kohm) is
obtained in the first stage, as well as the other three floors are
connected as a unity gain voltage followers. Every single output stage
drives independently through an amplifier output 50 pF capacitor towards
the resistance of 5.1 k ohm load. The response range is flat from 10 Hz
to 30 kHz.
