The AR-DM22-B is a 16-channel digital audio monitoring system featuring 20-segment tri-color LED bar graphs. Designed for ultra-near field audio monitoring in space critical environments, the AR-DM22-B is ideal for TV facilities, studios, postproduction facilities, VTR bays, mobile production vehicles, satellite links, and wherever multi-channel audio monitoring is required. The AR-DM22-B features stereo loudspeakers in a compact 2RU 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-DM22-B 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-DM22-B 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. 20-segment tri-color LED bar graphs allow simultaneous VU/PPM metering of 16 audio channels. Additional features include volume and balance controls, a headphone jack, and an RS-485 port for onsite firmware upgrades.
