A potentiometer is a three-terminal resistor with a sliding or ... User-accessible rotary potentiometers can be fitted with a switch which operates usually at the ...
A diagram showing the wiring of a Gibson Les Paul electric guitar. Shown are the humbucker pickups with individual tone and volume controls (T and V, respectively), 3-way pickup selector switch, tone capacitors that form a passive low-pass filter, the output jack and connections between those components.
A potentiometer is an instrument for measuring voltage or 'potential difference' by comparison of an unknown voltage with a known reference voltage. If a sensitive indicating instrument is used, very little current is drawn from the source of the unknown voltage.
Trimmer potentiometers or "trimpots" A trimmer, or preset, is a miniature adjustable electrical component. It is meant to be set correctly when installed in some device, and never seen or adjusted by the device's user. Trimmers can be variable resistors (potentiometers), variable capacitors, or trimmable inductors.
A digital potentiometer is built either from a resistor ladder integrated circuit or a digital-to-analog converter although a resistor ladder construction is the more common. [citation needed] Every step on the resistor ladder has its own switch which can connect this step to the output terminal of the potentiometer. The selected step on the ...
When the shaft of the potentiometer is rotated the resistance it produces either increases or decreases, the change in resistance corresponds to the angular change of the shaft. If coupled with a stable voltage reference, the output voltage can be fed into an analog-to-digital converter and a display can show the angle.
A line-level attenuator has lower power handling, such as a 1/2-watt potentiometer or voltage divider and controls preamp level signals, whereas a power attenuator has higher power handling capability, such as 10 watts or more, and is used between the power amplifier and the speaker.

Panning is the distribution of an audio signal (either monaural or stereophonic pairs) into a new stereo or multi-channel sound field determined by a pan control setting. A typical physical recording console has a pan control for each incoming source channel.
