Note:

AR-DM2X-X audio monitor shown with 3 modules: ARDM-AES-BNC, ARDM-AES-XLR, ARDM-AA-8XLR

Power Input Connector

Use only the included power supply to power the AR-DM2X-X audio monitor. The AR-DM2-1 and AR-DM21-B use
Power Supplies with 4-Pin XLR connectors providing 12-24 VDC, while the AR-DM22-B can use a universal AC Input
(110-230 VAC).

USB Port

The USB port is used to upgrade firmware to the AR-DM2X-X audio monitor. Additionally, the USB port can be used to
configure LKFS settings with USB memory stick.
Contact Marshall Electronics regarding available firmware upgrades and instructions.

I/O Module Slots

Four slots are available for a variety of I/O modules. See

page 13

for available modules.

Ethernet Port

The Ethernet port is used to configure several aspects of LKFS monitoring. Connecting the Ethernet port to your
network provides the ability to get current time from a NTP server, to export LKFS data to an FTP server or send
emails with LKFS data. Contact Marshall Electronics for further information on this feature.
