47K Rotary Dual Gang Potentiometer-D Shaft
This Panel Mount 47K Dual Log Potentiometer is a dual-ganged potentiometer that will satisfy all your stereo-signal needs. Instead of just one potentiometer, you actually get two separate pots, ‘ganged’ together. Turning the grippy shaft twists both standard logarithmic-taper 47Kohm potentiometers. It’s smooth and easy to turn, but not so loose that it will shift on its own.
Potentiometers, or “pots” to electronics enthusiasts, are differentiated by how quickly their resistance changes. In linear pots, 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 necessarily for audio controls. Volume controls have to cater to the human ear, which isn’t linear. Instead, logarithmic pots like this one increase their resistance on a curve. At the halfway point volume will still be moderate, but it will increase sharply as you keep turning up the volume. This corresponds to how the human ear hears. 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´s range.
