Audio Mixer With 3 Chanel Transistor
3 channel audio mixer is built using some of the transistor amplifier. 3 channel audio mixer circuit uses voltage 9VDC summber which can supplied from a battery. 3 channel audio mixer circuit is designed special for the purposes of this Public Amplifier. Because the audio circuit of this mixer is designed specifically for the purpose of a portable mixer for audio public then this series has only a volume control without the tone control. Image series that looks dibawh audio mixer is a series of mono, if you want to make a 3 channel stereo audio mixer it is necessary to make 2 pieces of a series of three channel audio mixer terebut. For more details, a series of three channel audio mixer Dapa seen in the picture below.

In a series of three channel audio mixer is equipped with a switch on each chanelnya which select the input impedance, when the switch SW1, SW2 and SW3 in the open then the input should come from the output signal with a high level such as VCD, MP3 player, tape, computer and tuner . And at SW1, SW2 and SW3 closed position, the input should come from a weak audio signals such as microphones.
