1U Tile attenuator with audio taper potentiometer
This is a passive attenuator using an Alps 50k log taper potentiometer. The Atten-A tile can be used to scale audio or control signals, however it is most useful on audio signals where it is often desirable to have the potentiometer rotation follow a decibel scale.
These merchants probably sell this module. Huh?
