Connect the battery or adapter with this audio mixer circuit. Enter Casset deck, or microphone output at input A1. Slowly rotate P1 toward maximum until the loudest sound was obtained but not broken. After that turn slowly toward a maximum until P4 obtained loudest sound but not broken. The same process performed on the input A2, A3.
Do not forget the time adjustment of S123 in the open position (ON position). After adjustment is complete, do not be amended again except P456 P123 that serves as a volume.
This audio mixer output can be connected to other recording media such as tape recorders, Cassette recorders, computers and much more. In addition, with the two LM 3900 you can have 6 channel audio mixer. Enough to build a simple studio and receive orders.
