What is the difference between log and linear pots?

What is the difference between log and linear pots?

Two types of potentiometers with different tracks are available. With linear potentiometers, the resistance between one end of the track and the wiper varies at a constant rate as the slider is moved along the track. In logarithmic types, the change in resistance is much less at one end of the track to the other.

How do you tell if a potentiometer is linear or logarithmic?

Use a multimeter. At “0” resistance should be 0, at “10” it will be whatever value the pot is i believe (250K, 500K etc) and then measure at “5”. If its half of the “10” value, then its linear. If its much smaller than half then its log.

Are volume pots linear or log?

So, log pots are generally preferred for volume because signal level ramps up, and down more smoothly that it does with linear pots. But not all log pots are the same. The most widely used guitar pots are made by CTS, and they offer ‘modern’ and ‘true vintage’ taper log pots.

What is the difference between A and B potentiometers?

500k “A” would denote an audio taper pot, and the “B” suffix would denote a linear taper pot. The only difference is the taper of the pot, or “how gradually it rolls off”. Most manufacturers use either (2) audio taper pots for volume + tone or would use audio taper for volume, and linear taper for tone.

Are alpha pots any good?

Alpha Pots: they’re everywhere and in everything. They have a great dampened feel, are fairly well made and are cheap. But I have spent some time cleaning these things up and/or replacing them. The inexpensive Bournes seem to be no better in this area.

Is linear potentiometer A or B?

Potentiometers made in Asia and the USA are usually marked with an “A” for logarithmic taper or a “B” for linear taper; “C” for the rarely seen reverse logarithmic taper.

Why would linear pots work better for balance than for logarithmic pots?

The other advantage of the ‘fake’ log pot is that linear pots usually have better tracking (and power handling) than commercially available ‘log’ pots, so there will be less variation in the signal between left and right channels.

Are tone pots and volume pots the same?

A Tone Pot is nothing but a regular pot, with a capacitor soldered to it. A Tone Pot will work the same way as a Volume Pot, but just a little different. Instead of sending the entire signal to ground, the tone cap helps by sending only a part of the signal to ground.

Which pots for humbuckers?

Humbucking pickups are typically paired with 500K pots and single coils are typically paired with 250K pots. Standard humbucking pickups tend to cancel out some of the higher overtones, so 500K pots are often used to prevent extra high end from bleeding off.

Can a log pot be used as a volume control?

Using a log pot therefore gives the effect that a setting of full volume on the control sounds twice as loud as a setting of half volume. A linear pot used as a volume control would give large apparent changes in loudness at low volume settings, with little apparent change over the rest of the control´s range.

What’s the difference between a linear taper pot and an audio pot?

And past “7” or “8” on the radio volume knob, it doesn’t really increase your volume anymore. It causes your signal to clip. A LINEAR taper pot increases the signal in a linear fashion. (“1” on your control is equal to 10%, “4” is equal to 40% and so forth) This works very different from an audio taper volume pot.

What’s the difference between logarithmic and linear potentiometers?

These are Linear (Lin) or Logarithmic (Log) tracks. With linear potentiometers, the resistance between one end of the track and the wiper varies at a constant rate as the slider is moved along the track. In logarithmic types, the change in resistance is much less at one end of the track to the other.

Why are logarithmic controls used in audio equipment?

Logarithmic potentiometers are used as volume controls in audio equipment because the response of the human ear to the loudness of sound is also logarithmic. Using a log pot therefore gives the effect that a setting of full volume on the control sounds twice as loud as a setting of half volume.
