For balanced operation, the screen should be connected to ground at the
amplifier end. To eliminate ground current loops, it can be lifted at the
WX3A output, provided normal safety requirements have been met (i.e. the
mains earths are correctly connected). See Fig 3.

6 WX3A SYSTEM CONFIGURATIONS WITH PLUG-IN BOARDS
The WX3A used in conjunction with a plug-in board becomes a dedicated
system controller. Depending on the plug-in system-specific board, the
WX3A is automatically configured either as a stereo 2-way or mono 3-way
device for a specific Wavefront system.
Each plug-in board dictates a system-specific crossover function,
equalisation and in some cases group delay.
