DUAL LEVEL is a 2 channel manual gain adjustment that can be used with CV or audio.
The meters display 0 volts thru +10 volts in 1 volt increments.   
The level knob is unity gain at the center detent position 
with reduction down to zero (CCW), and up to 2X gain (CW). 
Each channel has 2 identical outputs.  
The LED meter displays the output level.
With no input patched in, the LEVEL control sets a DC level from 0 to 10V.
Use to match or adjust modulation levels between modules 
with a visual reference of CV movement.
* The internal circuits are voltage protected post level control so that a non-eurorack audio or CV source can be used without harm to your system without clipping the higher voltage source.
