Quick Start Guide - Marshall Electronics AR-DM2X-X Operating Instructions Manual

Quick Start Guide

1. Install an Input Module
Ensure at least one input module is installed in the AR-DM2X-X audio monitor. If no modules are installed, see
Module Installation for detailed instructions.
2. Connect an Audio Source
Connect an audio source to the audio monitor. Depending on the chosen input module, the signal could be SDI
video with embedded audio, AES/EBU digital audio, analog audio, etc. Some modules may require a breakout
cable for the appropriate connections. See module specifications for details.
3. Power On the Audio Monitor
Supply power to the audio monitor by connecting the included power supply to an AC power source (100-240 V @
50/60 Hz) and connecting the power supply's 4-pin XLR connector to the back of the audio monitor. The Power LED
on the front panel will illuminate green.
4. Select an Input Module
Using the SRC switch on the front panel, choose the module location (1-4) to which the input is connected (Modules
are identified as numbers 1-4, with location no.1 on the far left if facing the rear of the audio monitor). The LED bar
graphs will then immediately show which channels have an audio signal present. You may not hear audio as yet.
5. Choose a Monitor Mode
To hear one audio channel at a time, press the Single button. To hear a stereo pair of channels, press the Pair
button. Use the Left and Right buttons to switch channels or channel pairs. The LEDs under each bar graph will
indicate which channels are selected. To hear channels 9-16, press the 9-16 button.
6. Adjust the Volume and Balance
Use the Volume and Balance controls to adjust the sound level and stereo balance.

Optional Modules
Input Modules
■ ARDM-AES-BNC
Features:
• 4 Unbalanced AES/EBU Inputs (8 Audio Channel Inputs)
• 4 Passive Loop-Through Outputs (8 Audio Channel Outputs)
• Accepts Professional (AES/EBU) and Consumer (SPDIF)
• Supports DOLBY Multi-Channel Decoding with Optional Module
• Embedded Metadata Display with AR-DM2-L Audio Monitor
Operation:
When using passive the loop-through outputs, unterminate the
corresponding inputs using the DIP switch (switches in DOWN
position). If the loop-through outputs are not used, terminate the
corresponding inputs (switches in UP position).
■ ARDM-AES-XLR
Features:
• 4 Balanced AES/EBU Inputs (8 Audio Channel Inputs)
• 4 Passive Loop-Through Outputs (8 Audio Channel Outputs)
• XLR Inputs and Outputs via included DB25-XLR Breakout Cable
• Supports DOLBY Multi-Channel Decoding with Optional Module
• Embedded Metadata Display with AR-DM2-L Audio Monitor
Operation:
1. Securely connect included DB-25 cable to module, tightening
screws on the connector.
2. When using passive the loop-through outputs, unterminate the
corresponding inputs using the DIP switch (switches in DOWN
position). If the loop-through outputs are not used, terminate the
corresponding inputs (switches in UP position).
■ ARDM-HDSDI
Features:
• HD-SDI Input (16 Audio Channel Inputs)
• Re-Clocked HD-SDI Loop-Through Output
• HD-SDI Supports SMPTE 259-C, 292M
• Supports DOLBY Multi-Channel Decoding with Optional Module
• Embedded Metadata Display with AR-DM2-L Audio Monitor
Operation:
SD and HD rates are automatically detected. Audio monitor must
be powered for loop-through output to function.
■ ARDM-AA-8XLR
Features:
• 8 Balanced Analog Audio Inputs
• 24 Bit A/D Conversion
• XLR Inputs via included DB25-XLR Breakout Cable
• Nominal Level: 0, +4, +6, or +8dBu = -20dBFS (Selectable)
Operation:
Securely connect included DB-25 cable to module, tightening
screws on the connector.
