. It could be log, or linear, or linear with an added resistor. This is fairly common type of pot. Either way, I don't think a reverse log pot would work well. Ein Poti mit einer logarithmischen Regelung bewirkt am Anfang des Regelbereichs (oder am Ende) einen großen elektrischen Signalsprung, danach nur noch geringe Änderung. Hier genau umgekehrt, für unser logaritmisches Gehör klingt dieses Poti linear. Zweimal Logaritmisch gleicht sich quasi aus There are potential slight differences, but you should be able to safely order a log pot and be happy with it. BTW, 'log' pots exist pretty much because of audio. I never see them in any other gear that I open. The human ear has a logrithmic response (as does human sight), hence the need to match the audio response with an electrical control
According to a wikipedia article, most log taper pots are actually two (or perhaps a few) linear potentiometers connected in such as way as to approximate a log taper. True log taper pots are apparently rather expensive In linear potentiometers, the amount of resistance changes in a direct pattern. If you turn or slide it halfway, its resistance will be halfway between its minimum and maximum settings. That's ideal for controlling lights or a fan, but not for audio controls. Logarithmic potentiometers increase their resistance on a curve I have a few unmarked pots laying around and I would like to know how to determine if they are linear or log pots. Is there a way to figure it out You need to use log for tone - linear will end up as an on/off tone switch right at or around 1. Volume pots are the ones that can use log or linear, depending on your personal preference. Just about all asian import guitars use linear volume now, though only a few of US makers have switched to linear volumes. Stock Fender style would be all audio pots
Potentiometers have different resistance tapers. A linear taper potentiometer has the same resistance change for given angle rotation of the shaft regardless of whether the wiper is at the lower, middle or top end of its travel. When starting from zero signal and increasing the control slightly, the audio signal will rapidly increase at first Logarithmic (Taper) Potentiometers. 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. 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. Most potentiometers will not list on the body of the pot if it is Linear or Logarithmic and it is often a question that is hard to answer for our customers. If the pot they have is still functioning you can often tell which you have by doing a simple resistance test on the potentiometer Volume pots are more moot, log is usually preferred but many LPs have linear. Linear is good if you want to make a small volume change from max. Linear pots are 50% at mid turn, so left or right wiring of them is all the same It is almost always used in a ganged configuration with a logarithmic potentiometer, for instance, in an audio balance control. Potentiometers used in combination with filter networks act as tone controls or equalizers. In audio systems, the word linear, is sometimes applied in a confusing way to describe slide potentiometers because of the straight line nature of the physical sliding motion. The word linear when applied to a potentiometer regardless of being a slide or rotary.
Beginner's video.In this video I talk about potentiometer taper, which is the relationship between the resistance of a potentiometer and its rotation. Most n... Most n.. If the resistance increases slowly, remains lower than 250k at the halfway point, and increases rapidly towards the end of the resistive strip, then the pot has a logarithmic response. This is generally referred to as 'log' or 'audio' taper' and an 'A' prefix is sometimes used to denote this Line-level audio is designed for 10k Ohm impedance. Using an incorrect resistance pot may result in distortion. If you use an audio taper pot but install it backwards, it will seem like you have almost no control over the volume for most of the pot's travel; the volume will suddenly go from almost nothing to almost full blast
Log/audio vs linear pots Discussion in 'Just Pickups' started by simond, Aug 2, 2016. Aug 2, 2016 #1. simond Tele-Holic. Posts: 508. Joined: Dec 26, 2011 Location: Tasmania . Hi all, I am putting together a guitar kit that my son got me for my birthday. It is a 175 inspired jazz box with standard two hb 4 knob setup. Came with two log pots and two linear. Convention wisdom (ie Google) seems to. .planetz.com/more-on-selecting-pots-and-evaluating-tapers. In this video, I demonstrate the sound differences between Linear and Audio taper pots,.. In a guitar, I prefer linear-taper pots for VOLUME controls and logarithmic (audio) tapers for my tone controls. But if I was building an AMP, I'd be using audio pots all over the place for tone-shaping and volume control. Except for the GAIN knob. I'd use a Linear-taper there. Because once you start to distort, there's a lot of character you can play with, but not if it's clean at 6, distorts.
Audio Taper (No Load) No Load - hot lug is disconnected from the resistive track, resulting in an open circuit at full rotation. ~R~ = nominal resistance of the potentiometer, measured between the potentiometer wiper and cold lug Volume pots should have logarithmic (A, audio taper) pots, when these are at 5 then the volume is half what it is a 10. This doesnt give exactly half the output voltage at 5, but it works the same as the way your ears work in response to the change in volume. Linear pots (B) pots, these give half the voltage output at 5 compared to 10, usually used for tone pots. When used as a volume pot, 5.

However, some disadvantages of using a linear potentiometer is that. Wiper can freely move up and down easily due to the long track ; Dust, dirt or sweat and grease may enter the open long track from the environment or the user. Digital Potentiometer. This article gets a little (a lot, actually) on the techy side of things. When it comes to potentiometers for guitars, there's this thing called taper. There are 4 kinds of tapers, and the designations for are logarithmic (also known as audio), linear, reverse logarithmic and graphic. Quick question answered 1: Why does the reverse. Audio taper potentiometers, which are potentiometers used in audio applications, to adjust the level or volume of sound, are all log tapers. Our ears perceive sound in a logarithmic fashion. If you were to use a linear potentiometer for volume control, increasing and decreasing sound, the volume changes would not turn out right 9mm Potentiometers for audio electronics. These pots work well in guitar pedals, synthesizers, Eurorack and other projects
In a guitar, I prefer linear-taper pots for VOLUME controls and logarithmic (audio) tapers for my tone controls. But if I was building an AMP, I'd be using audio pots all over the place for tone-shaping and volume control. Except for the GAIN knob. I'd use a Linear-taper there. Because once you start to distort, there's a lot of character you can play with, but not if it's clean at 6, distorts at 7, becomes buzzy by 8, overly-compressed by 9, and then super-muddy by 10. A linear taper might. To me the answer is 'yes' to 'audio or linear taper'. There is no correct answer - it's what you like, prefer, or possible a circuit may prefer. Kind of like guitars. If you like 'em - play 'em.. Linear Potentiometer has a similar function as the rotary potentiometer, but instead of the semi-circular resistance, there will be a linear resistor here with a sliding contact. The two ends of the linear resistor are connected across the source or input voltage, the output is taken between the sliding contact and anyone end of the linear resistor Linear is linear, Audio is Logarithmic. Basically, let's say for a volume knob you use a Linear taper pot, you'll get a huge range of volume for the first tiny bit of the turn and as you go up the knob the increase you get plateaus off, so the last half of a turn hardly does anything. If you use a Log pot it's more natural of a sweep for volume A = audio/logarithmic taper, B = linear taper, ###k is the resistance. There is no right or wrong as far as linear/audio for the tone control. Some prefer one over the other, but at either end of the sweep, they are the same. I personally prefer audio, but to each his own. Yes, you can wire a stereo jack. I'd probably ground the extra terminal.
You cannot use an ordinary logarithmic audio pot for the gain control because its response will be backwards. It should be linear or reverse-log type. If you use a linear pot for a volume control and turn it down to half then the volume will be reduced only a little. If you turn it down from half to 1/4 then the volume will be reduced a little more. When you turn it down almost to zero then the level will change a lot when the pot is moved only a little. A poor volume control Das lineare ändert sich hingegen gleichmäßig. Prinzipielles Beispiel: An beiden Potis liegen 10 Volt an, dann liefert der Mittelabgriff (nehmen wir an, es geht von 0 - 240 Grad) Drehwinkel 0° 60° 120° 180° 240° linear 0 2.5 5 7.5 10 Volt log. 0.001 0.01 0.1 1 10 Volt No disagreement. Most commercial logarithmic potentiometers are actually piecewise linear. Here is a good visual on the difference in characteristics . You can clearly see the two slopes. I did open up an audio pot years ago. The resistive track had two different widths, which caused the change in the slope of the resistance curve. Unfortunately, I did not take a picture. For this discussion, I was just treating the pots as if they were ideal
The most common form is the simple linear taper. In a linear taper, the relationship between the resistance and the potentiometer position is linear. This means that if the knob of the potentiometer is at the medium position, the output voltage is half of the voltage through the potentiometer. See the figure below EP-4385 CTS 250K Vintage-style Split Audio Pot. from $6.00. 250K ohm audio pot, CTS, vintage style, split knurled shaft with nut, lock and dress washer. Save Liquid error (product-badge line 32): -Infinity % Digipots are typically available with linear or logarithmic tap points. In addition, Maxim offers some further variations of the basic digipot. Nonvolatile digipots retain their last programmed wiper position when the power supply is switched off. OTP digpots set the wiper's power-on reset (POR) position to a user-defined value. All Digital Potentiometers . Typical applications and design. If you used an audio/log taper pot for the control of the power supply we mentioned, the output voltage would increase very slowly at first, creeping up to maybe 10% of the final output at 50% of the pot rotation. It would then blast the other 90% in the last half of the rotation - very hard to control. Likewise, if we used a linear pot for volume control, the volume would come up dramatically in the first half of pot rotation, and then do very little change in the last half
With logarithmic (aka audio) taper, that is not true; the resistance follows a logarithmic progression. Log taper is used because it gives a more natural progression when used for volume control. 5. Linear Pots increase/decrease signals in a linear fashion. (1 on your control knob equals 10%, 5 equals to 50%, etc.). Because of its predictability, many people prefer a. The most common taper or curve is linear and is not actually a curve but a straight line when plotted on a graph. The easiest way to determine if you have a linear taper is to place the shaft at the mid-point of the rotation and measure the resistance between the center terminal and either end terminal. If the shaft has a slot in it, then simply line up the slot with the center terminal of the potentiometer for the mid-point of the rotation. At that point the resistance measured between the.

POTENTIOMETER, Mesa/Boogie®, A250K, Audio Taper. 1/4 plastic D-shaft. A250K, audio taper, Mesa/Boogie part number 592148 or 593148. Used in Rectifiers (New and old) and Roadkings as the BASS pot in some channels. Used as the TREBLE pot in some Nomads and Road Kings. And many other applications. Unsure if this is the right part for your amp and the function in that amp
The result is dependent on the exactness of the linear taper,but it might be better than an average antilog pot (and cheaper). It is odd, but i've done it both ways, and i usually prefer the backwards standard audio pot to the linear pot with the resistor. Maybe my hearing isn't properly logarithmic Bei einem logarithmischen Potentiometer könnte die Bezeichnung 250KLOG lauten oder 250KA (A für Audio Taper = logarithmisch). Das B steht dann häufig für ein lineares Potentiometer. Hier würde die Bezeichnung also 250KB lauten. Es gibt allerdings auch Hersteller, die diese beiden Buchstaben genau anders herum verwenden! Darüber hinaus gibt es noch jede Menge. The log and antilog taper potentiometers are used to ensure that audio systems controls have linear characteristics as perceived by the human ear. Background Definitions phon The phon is a unit that is related to dB by the psychophysically measured frequency response of the ear. At 1 kHz, readings in phons and dB are, by definition, the same. For all other frequencies, the phon scale is. There are two choices for resistance taper: linear and log (audio). Digital potentiometers with a linear taper provide an equal change in resistance per unit of rotation. By contrast, devices with a log or audio taper provide a logarithmic change..
The taper you need for your potentiometer depends on the intended application. For potentiometers with a linear taper, the resistance between one end of the track and the wiper varies at a constant rate. If you turn the potentiometer halfway or slide the fader halfway along the track, the resistance will be half of the total resistance Abstract: Linear digital potentiometers (pots) can be used in nonlinear applications, such as adjusting volume control in audio applications. This article discusses how to create a \pseudologarithmic\ taper digital potentiometer (pot). This is achieved by simply adding a single resistor to the end of the digital pot when configured as a variable resistor In this case a smooth transition of tone is achieved using a logarithmic potentiometer. I to bought some Gibson 300k linear pots to put into my Gibson Les Paul Traditional Pro as it was clearly WRONG!!! with it's audio taper push/pull pots. So to sum up the guitar volume should be LINEAR taper and the guitar tone control should be LOG (Audio.

Some hot tips (or frequently asked questions.) A = Audio and L = Linear - Linear will give you even distribution of your volume as you turn it e.g. when turning your knob half way it has 50% of the sound passing through (a simplistic view) However Log is more of a curved taper.. See here for examples Logarithmic potentiometers are sometimes called audio potentiometers due to their use as volume control devices in audio ampli ers. Potentiometers with logarithmic resistive laws are necessary because the human ear responds to the logarithm of loudness, making control of ampli er output level smoother with a logarithmic potentiometer rather than the simpler linear device. The shape of the potentiometer response law is often called the po Taiss / 10pcs 100K Ohm 3 Terminals Linear Taper Rotary Audio B Type Potentiometer, Volume Control Potentiometer B100K + 10pcs Knob (Black and Gold Each 5） 4.5 out of 5 stars 50 $9.99 $ 9 . 99 ($1.00/Item
Potentiometers are usually classified as in to two types based on the Taper characteristic. They are: Linear Taper; Logarithmic Taper; Linear Taper. The most commonly found Potentiometers are of Linear Tapper type. In this type, the relation between the position of the Wiper and the resistance is linear. This type of POTs are usually marked.

For logarithmic taper potentiometers, the resistance does not vary at a constant rate. The level of resistance moves exponentially up or down. A potentiometer that has been turned or moved halfway along its track, will not produce resistance that is half the total resistance. Logarithmic potentiometers are commonly used for audio applications Some older potentiometers may use an antilog (or reverse audio) taper; these devices were marked 'F' and are not regularly produced today. In order to cut manufacturing costs, many suppliers construct potentiometers using two varying resistive elements joined together to achieve a hybrid between linear and logarithmic tapers They are often used for audio mixing and lighting control. Linear Taper vs. Logarithmic Taper. Getting more exotic. Most potentiometers for regular use are linear taper potentiometers. The value of the resistance varies linearly as you adjust it, from 0 to 100% of the adjustment. In the examples in this guide, this gives a nice, even set of numbers and pixels as the potentiometer is adjusted. For audio volume control an audio-taper pot (giving approximately a logarithmic change in output level versus pot rotation) is desired to match the logarithmic response of the ear to sound level. That gives a perceived linear change in loudness level versus pot rotation. Although reasonably common, sometimes an audio-taper pot is not readily available, particularly for an odd form factor or. Tone pots should always be log/audio taper. I use linear taper vol pots because I want a fine control going down from 10. I nearly always have the vol rolled back to 6-8, I set up the amp with it at 5. This may sound like a long way but it is not on a linear pot. On a linear pot the 50% position is 5. On a log pot the 50% position is near 8. However the gradual increase on a log pot is up from.
Logarithmic, carbon composite track stereo potentiometer, suitable for use as a volume control. Rated at 0.25W, 250Vdc. Alps blue beauty An encapsulated stereo, dark blue plastic bodied, dual pot used in numerous high quality applications. Alps blue beauty motorised. Exactly the same characteristics as the blue beauty, but with the added convenience of being motorised. Audio Note 100K. This type of potentiometer is often used in audio volume control (logarithmic taper) as well as many other applications. Different materials are used to construct potentiometers, including carbon composition, cermet, conductive plastic, and metal film. Rotary Potentiometers. These are the most common type of potentiometers, where the wiper moves along a circular path. These potentiometers are. An audio taper pot makes the function of the Tone control more linear; it flattens out the curve, as you hear it. That's why they make audio taper pots. A linear taper pot in a passive Tone control circuit makes the operation of the circuit uneven, gradually increasing. The effect of the capacitor starts out slowly and then comes on stronger. The volume control, certainly with passive circuits, should be linear. Going from 10 to 9 should be a 10% reduction, not 26%. The tone control is a different deal. It works as a combination of resistance (the pot) and capacitance (that pesky cap). That is not a linear function and using a audio taper pot gives a smoother response curve As you know, because of how the human ear hears, any Volume or Audio Gain potentiometer needs to have a Logarithmic (base 10) track. Similarly, for a proper balance control you need a proper Balance pot . . . This is a dual-gang Logarithmic potentiometer, where one of the gangs is normal Log, and the other is reversed

Teilweise sind jedoch auch logarithmische Potentiometer mit B gekennzeichnet, beispielsweise im. Linear potentiometers produce a resistance output that varies according to the displacement or position of a slider or wiper. They are variable resistors with three leads. Two leads connect to the ends of the resistor, so the resistance between them is fixed. The third lead connects to a slider that travels along the resistor varying the resistance between it and the other two connections. The. Slide Potentiometer, Log, 10K, 30mm. ALPS ALPINE.
