<pre>
 
The D107 is a very simple dual slew rate limiter. It can be 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.
 
 
Specifications:
 
 
Dual slew rate limiter
 
Control range of 0-10s (approx.)
 
Power: +12V @ 5mA, -12V @ 5mA
