Front Panel Features
Stereo Loudspeakers
The stereo loudspeakers are active unless
headphones are connected.
Power Indication LED
The power LED will illuminate green when power is
supplied to the audio monitor.
Headphone Output
The headphone output accepts stereo headphones
with a 1/4" TRS connecter.
Mute Button
The mute button disables the speakers and
headphone output.
Volume Control
The volume control affects both the stereo speakers
and headphone output.
Balance Control
The balance control adjusts the relative level of each
channel in the current stereo mix.
SRC Switch
The source switch is used to select the module
source from which to monitor audio.
LED Bar Graphs
The LED bar graphs display signal presence and
VU/PPM information for 16 channels of audio.
Channel-Assign and DOLBY Indicator LEDs
The channel assign LED below each bar graph
indicates how that channel is being reproduced
through the stereo speakers. The DOLBY LED below
each channel pair indicates the presence of a DOLBY
encoded signal.
Monitor Modes
The single, pair, and mix buttons are used to select
the mode in which to monitor audio channels.
Left and Right Navigation Buttons
The left and right buttons are used to select single
channels, channel pairs, or downmix configurations.
DOLBY Decode Button
The DOLBY decode button is used to decode the
DOLBY signal on the selected channel pair (ARDM-
D552 Module required).
9-16 Button
The 9-16 button is used to monitor and downmix
channels 9-16 from the selected input module. The
LED on the 9-16 button will illuminate when channels
9-16 are selected.

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).

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).
