Installation and Initial Setup
Unpacking
Carefully unpack the AR-DM2X-X audio monitor and verify that the following items are included:
• AR-DM2X-X Audio Monitor*
• AC Power Cable or XLR Power Supply
• Operating Instructions
* AR-DM2X-X series monitors may be pre-configured with input/output modules or DOLBY module if ordered as such.
DOLBY module installation is indicated by a label on the exterior of the unit.
Inspect the unit for any physical damage that may have occurred during shipping. Should there be any damage,
immediately contact Marshall Electronics at [phone]. If you are not located within the continental United States,
call [phone].
Input / Output Module Installation
If your audio monitor has not been pre-configured with input and output modules at the factory, you must install at least
one input module to use the audio monitor. Additional modules can also be purchased and installed when needed. The
modules are designed for simple installation and removal without tools. For detailed instructions, see Module
Installation.
Note: Modules cannot be installed or “hot swapped” while the audio monitor is powered on. Ensure that the audio monitor
is powered off before installing or removing modules.
Audio Monitor Installation
The AR-DM2X-X audio monitor series can be installed in an EIA-standard 19-inch rack. Alternately, the AR-DM2X-X
audio monitor can be placed on any level surface. For optimum sound quality, the audio monitor should be installed at ear
level.
