Features
- Simple dual slew rate limiter
- Used for portamento effects or to smooth out a stepped voltage from a sequencer, or for general audio or CV smoothing
- Each channel contains a buffer with 100K input impedance suitable for pitch CVs
- The slew pot affects the charging of a large capacitor connected to a second amplifier
- The second amp provides buffering for output to isolate the output jack from the actual slewing function
- Control range of 0-10s (approx.)
- Power: +12V @ 5mA, -12V @ 5mA
