Description
9mm single link precision adjustable carbon film rotating potentiometer for electric guitar effects, audio
Product Description Audio control
Single Unit, Horizontal Type
1. Insert molding with resh around the resistor prevents flux
build-up.
2. Available with a wide choice of shafts.
3. Solderable metal is used in teh snap-in mounting section.
* Dust-proof construction without any opening part.
The 'log pot', that is, a potentiometer has a resistance, taper, or, "curve" (or law) of a logarithmic (log) form, 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. It ensures that on a volume control marked 0 to 10, for example, a setting of 5 sounds subjectively half as loud as a setting of 10. There is also an anti-log pot or reverse audio taper which is simply the reverse of a logarithmic potentiometer. It is almost always used in a ganged configuration with a logarithmic potentiometer, for instance, in an audio balance control.

Workshop
We have a complete set of production processes. Automated equipment is used to speed up production in mass production, and then manual production lines are used to inspect all products one by one, including resistance tolerance, appearance size, sliding noise, service life, temperature test, salt spray test, etc. Finally, professional packers will use the safest and most space-saving packaging to package the products after all the tests are qualified, saving freight costs.
Finally, there is fedex, DHL or UPS, which is designated by the customer to request the Courier to deliver the goods.
Potentiometer in the circuit of the main role has the following aspects
1. Used as a voltage divider
A potentiometer is a continuously adjustable resistor in which
moving contacts slide on the resistor body when adjusting the
potentiometer's turn or slide handle. At this time, the
potentiometer output terminal can be obtained and potentiometer
applied voltage and movable arm Angle or stroke into a certain
relationship of the output voltage.
2. Used as rheostat
When potentiometer is used as rheostat, should connect it into two
ends device, inside the range of stroke of potentiometer so, can
obtain the resistance value of a smooth and continuous change.
3. Used as current controller
When the potentiometer is used as a current controller, one of the
selected current outputs must be the sliding contact leads.
