Ground Isolation Jumpers
Each of the eight balanced connectors (the analog and AES/EBU digital I/O) can individually
isolate pin 1 from ground if desired via an internal jumper block.
Table 3 below indicates which internal jumper is used for each balanced connector. Pin 1 is tied to
ground for the connector when the indicated pair of pins is jumpered.
The 2192 is shipped from the factory with pin 1 connected to ground on all eight connectors.
Important: Changes to internal jumpers should only be made by qualified personnel.
Disconnect AC Power before opening the unit!

Pin 1 is tied to ground when a jumper is across the pair of pins.
