The input and outputs of the EQX20 are balanced on both XLR and 1/4"
TRS jack connectors. For balanced input and outputs, connections to the
unit should be wired as follows:
TRS jack -10dBV
Tip Hot (signal +)
Ring Cold (signal -)
Sleeve Screen (signal ground)
For un-balanced operation join Ring and Sleeve on input, output or both
Sleeve
Screen Ring
Cold (-)
Tip
Hot (+)
XLR
+4dBu Pin 1 Screen (Signal ground)
Pin 2 Hot (+ve)
Pin 3 Cold (-ve)
For un-balanced operation join pins 1 and 3 on input, output or both
Pin 1 = Screen Pin 2 = Hot (+)
Pin 3 = Cold (-)

The 20kΩ input impedance of both inputs is suitable for most types of
equipment.
Plugging a mono jack lead into the TRS input will effectively un-balance the
signal connection.
