Use the wiring conventions shown below. The 2-core method is preferred over the 1-core method as it gives increased noise immunity and less signal distortion. It is important that all of the connections are made otherwise there could be a loss of input signal level (e.g. XLR pin 3 left floating) or induced hum (e.g. chassis ground and audio ground connected together) due to ground loops.
Note: do not connect the XLR chassis to XLR pin 1, as this will compromise the RF immunity of the monitor's electronics.
