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 ...
The Griffin PowerMate was officially supported on Mac OS X, Windows XP and Vista.Griffin's software for Windows works under Windows 7 and 8 but crashes occasionally; for macOS, there is no official support past 10.12 ("Sierra", released in 2016), though their USB version and configuration software (PowerMate Manager) continues to work on later versions.
Remote control consoles use audio level compression in transmit and receive audio paths. In documentation for most any console, receive audio is described as having a 30 decibel (db) knee of compression: for a 30 db variation in input audio level, the speaker volume changes by 3 db. [8]
A pan control or pan pot (short for "panning potentiometer") is an analog control with a position indicator that can range continuously from the 7 o'clock when fully left to the 5 o'clock position fully right. Audio mixing software replaces pan pots with on-screen virtual knobs or sliders which function like their physical counterparts.
For movie soundtracks this reference volume level is an industry standard [4] and can be used by manufacturers to provide a loudness feature that works with a reasonable degree of accuracy. A home theater product that provides a reference level indication on the volume control can be expected to work well with movie soundtracks.
