Inputs 1-4
The input section of the 482 DriveRack™ offers four electronically balanced XLR connectors.
Inputs 3 and 4 offer Line/RTA switches that allow you to run a real time audio analyzer micro-
phone directly into the input of the 482 DriveRack™. The four XLR inputs of the 482 DriveRack™
also offer Pin 1 lift switches which lift the ground of the selected XLR input pair when pressed.
Warning - For proper operation of the RTA microphone, the RTA button must be depressed and
the ground /lift switch must be in the grounded position. When the RTA button on the back panel
is depressed, 48V phantom power is applied to pins 2 and 3 of the XLR connector. To maintain
a proper ground return for the phantom power, the ground/lift switch must be in the grounded
position. This will prevent the possibility of electrical shock.
