SL3HP Fader Module SL is a Bi- or Uni-Polar Attenuator and Voltage Source with a Slide Potentiometer. Each SL can also be a mixer channel when several SLs are daisy-chained.  Any audio or voltage source may be attenuated using the slide potentiometer. You can change the behaviour from uni-polar to bi-polar via switch. If there is no input patched SL acts as a manual voltage source. Voltages can be set to +5V or +10V via switch. This mode also allows you to change the behaviour from uni-polar to bi-polar.  Two or more SL modules may be daisy-chained with simple 2.54mm jumpers on the back. This way you can use them as mixer channels or offset generators. When SL 1’s output is left unconnected, the signal on SL 2’s output is the sum of SL 1 and 2. When output 1 and 2 are left unconnected, the signal on SL 3’s output is the sum of channels 1, 2 and 3 and so on. Leave SL 1’s input and output unconnected. Patch a CV source to SL 2’s input. SL 2’s output will be an offset copy of the input signal. Use SL 1’s slider to adjust the offset and use SL 2’s slider to adjust the amplitude and polarity of the CV. If you patch an input in SL 1´s input and take the output from SL 2, the signal will first be attenuated and then offset.  You can choose to have the jacks on top or bottom by flipping the panel and changing the slide pot direction via two jumpers on the back.
