All audio inputs and outputs use one 3-position, 3.5mm Euro connector for each channel. GPIO uses one 10-position 3.5mm Euro connector for 
eachrow (not applicable to the Core 110f v2).
All inputs and outputs are configured in Q-SYS Designer Software.

1.  Mic/Line Inputs – eight channels, balanced or unbalanced, 
phantom power – orange
2.  Flex Channels – eight user-configurable input/output 
channels, balanced or unbalanced, phantom power on 
inputs – blue
3.  Mic/Line Outputs – eight channels, balanced or unbalanced 
- green
The following connections use the black Euro plug and are not 
applicable to the Core 110f v2:
4.  12VDC, 0.2A Outputs  + uses connector pins 1 and 11 
(notnumbered)
5.  General-purpose Inputs – 16 inputs, 0-24V analog input, or 
contact closure (Pins labeled 1–16 equal pins 1–16 in the 
Q-SYS Designer GPIO Input component)
6.  Earth ground – uses pins 10 and 20 (not numbered)
7.  General-purpose Outputs – 16 outputs, open collector 
(24V, 0.2A maximum) with pull up to +3.3V (Pins labeled 
1–16 equal pins 1–16 in the Q-SYS Designer GPIO Output 
component)
