Maximum Output Level Adjustment 

The V1636 has two rotary Hex Switches for adjusting the MOL (

L

evel) of 

each of the channelpairs A and B.  Looking at the V1636 with the Euro connector on the right 
hand side, the right switch is for channelpair A (L and R) and the left switch is for channelpair 
B (L and R).  The location of the MOL switches is shown on the figure below.  These 

 

switches 

adjust the analog MOL corresponding to 0dBFS digital input in 1dB steps from +14dBu to 
+28dBu.  The table below shows the correspondence between the 16 switch positions and 
the max output level setting for the V1636.
