This electronic schematic circuit is a very simple two way electronic intercom circuit based on a LM386 audio amplifier circuit . The electronic intercom schematic use two separate LM386 circuits one amplifier for each station .
The LM386 based intercom electronic circuit operate as two separate entities with switches at either station controlling which will transmit or receive . The value of the capacitors from the electronic schematic are in microfarads .For this intercom circuit you can use a 8 ohms speaker , one for each station . The intercom circuit require a 9 volts dc power supply . With the C7 and C8 capacitors connected in the circuit the amplifiers provide a high gain around 200 and without these two capacitors connected in the circuit , the gain drop s around 20 .
