Hybrid 2 channel audio mixer circuit

A very simple hybrid 2 channel audio mixer electronic project can be designed using few external electronic components . This hybrid 2 channel audio mixer has two inputs and with independent control for each channel .

IC1 a and IC21 b are biased into the linear regions by R3 and R4 . Outputs from gates are combined by op amp IC2, which provides low impedance output .
For this you require a 5011 logic gate IC and a 747 operational amplifier for IC2 .
This electronic project mixer can be powered from a DC power supply that will provide an output voltage between 6 and 15 volts .
This audio mixer electronic circuit is very simple requiring few external electronic parts and can be used in some audio projects where space is critical .
