2 channel manual gain adjustment

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.
