Ground Isolation Jumpers
Each of the eight balanced connectors (the analog and AES digital I/O) can individually isolate pin 1
from ground if desired via an internal jumper block. The table 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 of
these connectors.

(Note: Pin 1 is tied to ground when a jumper is across the pair of pins)
Fuse
There is no user accessible fuse for the 2192. It contains an internal power supply circuit board with
its own fuse. (Fuse type: T 2A 250V.)
Voltage Select
The 2192 contains a universal auto-sensing, filtered, multi-stage regulated power supply which
supports 100-240VAC and 50-60Hz power for trouble-free operation worldwide. No switch setting is
required when changing from 115 to 230 volt use or vice versa.
Changes to internal jumpers should only be made by qualified personnel. Be sure to
disconnect AC power before opening the unit!
