1U Tile slew limiter.
This Tile slews the input signal according to the pot setting, and sends it to the output. On the rear of the unit is a dip switch which sets the slew range from very slow to very fast (see picture). It may be desirable to have a couple of Slew Tiles in a system with different range settings on each.
