Volume potentiometer is actually a three-wire logarithmic variable resistor!

What volume potentiometer wiring it?

As shown below, the first intermediate amplifier connected to the input terminal early grounding line, trailing wire to the audio signal output sources to use shielded cable metal jacket! Jacket ground!
Two dual-channel coaxial! Same wiring! Grounding separately!

　　Uses a double potentiometer, you can control the stereo volume.

As shown above can be used for volume control potentiometer connection reference.

　　The figure is double potentiometer ordinary 6 feet, 8 feet if that is generally left two is used for loudness, you can not answer, 6 feet potentiometer connection reference image.

Pot generally linear curve type (B type) and exponential (A type) of two types.

　　If you control the volume using 1 connection, you should use exponential potential, so that the same angle potentiometer adjustment, volume change the human ear is almost identical.

  In some cases, such as tone circuits, it may require linear potentiometer.

　　Linear potentiometer resistance is generally labeled as BXXX, XXXB etc.

　　Index potentiometer resistance is generally labeled as AXXX, XXXA etc., XXX refers to the potentiometer resistance.

　　For example B50k, it is a linear potentiometer, the resistance 50k ohm.
