Volume and tone controls were 500k Audio taper pots.
2.
In principle any relationship is possible, but for most purposes linear or logarithmic ( aka " audio taper " ) potentiometers are sufficient.
3.
There is also an " anti-log pot " or " reverse audio taper " which is simply the reverse of a logarithmic potentiometer.
4.
The'log pot'is used as the volume control in audio power amplifiers, where it is also called an " audio taper pot ", because the amplitude response of the human ear is approximately logarithmic.
5.
In receivers equipped with A . V . C ., volume levels are adjusted by a potentiometer ( typically 500 k? to 2 M? audio taper ) that controls audio signal levels at the control grid of the A . F . amplifier.
6.
Another type of curve is called the logarithmic ratio ( also known as " audio taper ", or an inverse-logarithmic ratio . the log / audio-taper more closely matches human hearing, with finer control at lower levels, increasing dramatically past the 50 % point.
