3. Installation
Mounting the Receiver
The ENIGMA XM88422 receiver is shipped by default
with a standard 3HE 19” desktop housing. The
housing can be extended using rack extender
brackets to 6 HE or more enabling the receiver to
build in additional Line Car
ds. Optional 19” rack
mounting brackets can be used to install the receiver
in standard 19” rack housings.
The LCD screens on the receiver are designed to be
viewed below eye level. If the receiver has to be
mounted above eye level, it is suggested to angle the
unit downward to improve visibility.
The following items can be supplied for installation:

interconnect cables and 2 blank cover plates.
