The Module A-171-2 is a voltage controlled slew limiter with added features beyond a simple slew limiter.

The Module A-171-2 features include:

• 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, affected by the CV Up Control and the corresponding exp./lin. switch
• CV Down Input, affected by the CV Down Control and the corresponding exp./lin. switch
• CV Up and CV Down sockets are normalled
