Required for multi-channel decoding
Featuring four models (two 1RU and two 2RU units), the AR-DM Series Digital Rackmount Audio Monitors are ideal for TV facilities, studios, post production, VTR bays, mobile production vehicles, satellite links, and wherever multichannel audio monitoring is required. All models support 16 audio channels with four slots available for interchangeable input / output modules. The AR-DM series provides pristine audio quality and unrivaled flexibility with 100% digital processing, Class D (digital) amplification, selectable stereo downmix modes, Dolby Digital / Dolby E decoding capability (with optional Dolby E module), a headphone jack with Level control, and an RS-485 port for on-site firmware upgrades.
The AR-DM1 provides tri-color LEDs for monitoring signal presence and system status while the AR-DM1-B and AR-DM2-B provide 10 and 20-segment tri-color bargraphs respectively. Both VU and peak metering are supported. The flagship AR-DM2-L provides dual 4" high resolution 640xRGBx480LCD monitors capable of displaying a wealth of information, including a high contrast, tri-color 16-bargraph display in one window while showing critical Metadata or Channel Status information in the other. Channel, Group, Mix, Dolby, Balance selection, and saved configurations are easily accessed via the system's large navigation buttons. For audio playback, 1RU units provide twin loudspeakers, while 2RU models provide larger, high performance transducers and subwoofer.
