Doepfer - A-170: Dual Slew Limiter
Module a-170 contains two separate slew limiters, also known as portamento controllers or integrators. the first sl has just one joint control, which sets both rise and fall times (c. 0 ...10 sec). the second sl has separate controls for rise and fall times, and can therefore be used as a simple ar envelope generator. over and above this, you can set the overall range for these parameters, with a three-position switch, as on the full adsrs.
both slew limiters have two leds each, to show the state of the rising and falling voltages.
this module has a maximum current draw of 20ma. it requires 8 te/hp worth of space to fit in a eurorack frame.
