Unpacking
Carefully unpack the AR-DM1 audio monitor and verify that the following items are included:
• AR-DM1 Audio Monitor
*
• Power Supply with 4-Pin XLR Connector

• Operating Instructions
*
AR-DM1 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 (800) 800-6608. If you are not located within the continental United States,
call +1 (310) 333-0606.
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
(page 15)
.
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-DM1 audio monitor can be installed in an EIA-standard 19-inch rack. At only 7.8” inches deep, the AR-DM1 can
also be installed in many shallow racks cases. Alternately, the AR-DM1 audio monitor can be placed on any level surface.
For optimum sound quality, the audio monitor should be installed at ear level.
