      Description

      Manufacturer Description:

      Module a-171-2 is a voltage controlled slew limiter with a lot of additional features beyond a simple slew limiter. it's mostly a licensed copy of ken stones vcs which is in turn based on the serge vcs.

      these are the most important features:
      manual control of the slew-up time

      cv control of the slew-up time with polarizer

      switch for linear/exponential shape of the rising section of the response curve

      manual control of the slew-down time

      cv control of the slew-down time with polarizer

      switch for linear/exponential shape of the falling section of the response curve

      signal input: the "to-be-slewed" signal

      cv up input

      cv down input

      cv up and cv down sockets are normalled

      exponential cv input: named "v/oct" in the original design but as it's not really exactly 1v/oct we will name this input probably "exp.cv", mainly used for vclfo/vco applications in cycle mode or as common exponential control for both up and down times in slew mode

      trigger input: used for envelope generation or retrigger in lfo/vco mode, a pulse at the trigger input will start the envelope or retrigger the lfo/vco

      end output: turns high as the output falls below about 20mv, turns low as the outputs goes beyond about 3.5v, in cycle mode a rectangle signal is generated

      cyle on/off switch: when "on" the end output is internally connected to the trigger input to generate cyclic signals like an lfo

      output: the output of the slew limiter

      led display: displays the slew limiter output signal

      typical applications:
      cycle switch = off, no trigger signal applied to trig socket: voltage controlled slew limiter or portamento generator: the signal applied to the signal input is "slewed". the slew up and down times are controlled manually by means of the up and down controls, the effect of the cv up and cv down control voltages are controlled by the cv up and cv down controls, in exponential mode these controls also affect the slew shape (see symbols at the ccw and cw positions of the controls)

      cycle switch = off, trigger signal applied to trig socket, no input signal: envelope generator, the rise and fall times are controlled like the slew up/down times above

      cycle switch = on, no trigger signal applied to trig socket, no input signal: voltage controlled lfo/vco, the rise and fall times of the waveform are controlled like the slew up/down times above)

      this module requires 8 te/hp worth of space to fit in a eurorack frame.
