Product Overview
The AR-DM1 is a 16-channel digital audio monitoring system featuring 16 LED channel presence indicators. Designed for
ultra-near field audio monitoring in space critical environments, the AR-DM1 is ideal for TV facilities, studios, post-
production facilities, VTR bays, mobile production vehicles, satellite links, and wherever multi-channel audio monitoring is
required.
The AR-DM1 features stereo loudspeakers in a compact 1RU form factor, with Class D Amplification and 100% digital
processing providing pristine audio quality. Interchangeable input and output modules provide unrivaled flexibility – up to
four I/O modules can be installed in a single AR-DM1 audio monitor, each module with up to 16 channel inputs, providing
a possible 64 channels per audio monitor. Input choices include balanced/unbalanced AES/EBU, SDI video with
embedded audio, and balanced analog audio. With an optional DOLBY
®
module, the AR-DM1 supports decoding and
monitoring of
DOLBY
®
E
and
DOLBY
®
DIGITAL
(AC-3) signals, with the option to output discrete decoded channels or
pass through encoded bit streams. Flexible monitoring modes include mono, stereo, and various stereo downmix
configurations for multi-channel audio. Sixteen dedicated LEDs indicate digital or analog signal presence for 16 channels
of audio simultaneously. Additional features include volume and balance controls, a headphone jack, and an RS-485 port
for on-site firmware upgrades.
