What Potentiometer To Use For Volume Control

What potentiometer to use for volume control

In general, you want the potentiometer to be as small as possible without putting too much of a load on the source. A quick rule of thumb for selecting the resistance of a potentiometer is that you want the input impedance to be an order of magnitude (10 times) higher than the output (source) impedance.

Can a potentiometer control volume?

A potentiometer or “pot” used for volume control has an audio taper. The taper of a pot describes the percentage of resistance available based on the percentage the control knob is turned. A linear taper pot presents half of its rated resistance when the knob is midway thorough its rotation.

How do I know what size potentiometer to use?

The best way to determine the type, or law of a particular potentiometer is to set the pots shaft to the center of its travel, that is about half way, and then measure the resistance across each half from wiper to end terminal. If each half has more or less equal resistance, then it's a Linear Potentiometer.

What is a volume potentiometer?

A potentiometer or “pot”, is a variable resistor that changes your tone or volume by increasing or decreasing resistance. Adding a capacitor or “cap” to the pot turns it into a simple EQ. Turning the wiper adjusts the amount of resistance and, in turn, determines which frequencies are allowed to pass.

Can I use 100K potentiometer instead of 10k?

So a 100K potentiometer has ten times the resistance of a 10K potentiometer. Which one you would choose depends on the application—it's often a tradeoff between some form of the following two factors: At a given voltage, the 100K pot will draw less current, which could reduce wasted energy and improve battery life.

What is the difference between a 250K and 500K potentiometer?

A 500K pot provides the most resistance, so high frequencies from your signal are not bled to ground as easily as a 250K pot. Similarly, the 250K pot contributes less resistance and thus bleeds more high frequencies to ground.

What pots to use for volume?

Generally speaking, to control volume, humbuckers should be paired to 500k pots, while single-coil pickups should be paired with 250k pots. A 500k volume pot offers twice the resistance to the current flowing from the pickup to the output jack versus a 250k pot when turned up to maximum.

Can I use 50K potentiometer instead of 10k?

If they used as rheostats then you could use a 50K pot with a 12.5k resistor in parallel which will make the resistance vary between zero and 10k but the result will be vey non-linear - most of the variation happening towards the zero end of travel.

What are the 4 types of potentiometer?

There are four types of linear potentiometers based on their applications: Slide, Dual side, Multi-turn slide, and Motorised fader potentiometer.

Can I use a 5K potentiometer instead of a 10k?

You 'Can' fudge the value though if you design for a 10K but the desired result occurs when the potentiometer is set to less than 5K then you can use a 5K... you cannot use lower, and you can most certainly use higher.

What pots for volume and tone?

Either 250K or 500K pots can be used with any passive pickups however the pot values will affect tone slightly. The rule is: Using higher value pots (500K) will give the guitar a brighter sound and lower value pots (250K) will give the guitar a slightly warmer sound.

What is a 10k potentiometer used for?

A 10k potentiometer (a.k.a "pot" or "knob") is an electronic component that can be used to control the flow of electricity through a circuit, much like a faucet regulates the flow of water in your home.

Are volume pots A or B?

The general convention for pots is that A is an audio/log taper and B is linear. For smooth control of volume, you should always use an A type audio/log taper pot. Using a linear pot here will give a very sudden volume reduction when going from 10 to 9.

What are the three types of potentiometer?

There are three main categories that potentiometers are classified into Linear Potentiometer, Rotary Potentiometer, and Digital Potentiometer. Each of them has been tailored for specific needs. But rotary POTs are the most commonly used potentiometer type.

What is the difference between 50K and 100k potentiometer?

100K and 50K pots are the same, their division factors will be the same at a given rotation position. The difference between the two pots is the overall resistance they present across the source.

What does a 100k potentiometer do?

The numeric value tells the value of resistance. 1k means that the pot will provide resistance up to 1000 ohm. 10k & 100k means it will provide ten times and 100 times more resistance than 1k, respectively. The lesser the resistance value, the more the current drawn by that pot.

What is the difference between 10k and 50k potentiometer?

The main difference is the impedence of the pot. If I am correct in thinking this, the 10k will get louder faster since it has less resistance on the voltage. However, some sources may not appreciate driving a 10k ohm load, so 50k helps here.

How much current can a 10k potentiometer handle?

I.e 10 mA. That applied to the voltage across the full 10000 ohms. That also means that you cannot pass more than 10 mA into the Wiper.

Are 500K pots louder than 250K?

The first to go are the ultra-highs, and the lower the value of the pot, the greater the amount of signal that can escape to ground. This is why 500K pots keep your sound brighter than 250K: their higher resistance won't allow as much of the signal to bleed off.

Are 25k and 250K pots the same?

the lower the number on the pot (25k, 100k, 250k, etc), the more highs the pot will attenuate (or bleed off) from your signal. the higher the number on the pot (500k or 1meg), the more highs the pot will allow through to your signal.
