ant to create an amplifier that mixes two tones
together? There are many different types of tone
m
ixing circuits, but the operational amplifier is
considered one of the best.
After you complete the wiring, slide the switch to
position A to turn on the power. Note the timbre (the
tone) of the sound produced. To mix this tone with
another, press the key. You can alter the two
separate tones by changing the values for the two
10kW resistors.
The tone mixer amplifier allows you to mix two tones
together by modifying resistances with no need to
change the other circuits.
