XLR shells

XLR pin 1s should only be used to provide a ground connection for cable screens. The shell (body) of cable XLRs also need to be connected to ground so they provide a screen for the terminals, but they should not be wired internally to the pin 1 terminal. Their ground should be prevented from contact with the panel XLR connector body. This is particularly important for unbalanced connections where an internal connection from pin 1 to the connector shell could compromise ground lifting schemes. With this wiring arrangement, joining XLR cables together to increase the overall length is best avoided, because the joint will not be properly screened. However, if absolutely necessary it is unlikely to cause major problems.

Signal ground bonding

If an unbalanced connection is required to external equipment with signal grounds that cannot be isolated from safety earth it will be difficult to eliminate ground loop currents, but their effects can usually be reduced. The currents within a ground loop will generate small voltages in the cables, including the signal grounds. Any voltages that develop in the signal grounds will appear as noise errors in the audio. If the impedance of the screen cables is reduced, the voltage developed by the ground loop will also be reduced. So, if the impedance can be zero there will be no noise. This is difficult to achieve, but ground bonding the external equipment rack to the chassis of the VeniceU will have a similar effect and will significantly reduce noise in unbalanced connections between the two locations.
