The DVRAS is a 2U rackmountable processing module for use in Constellation® acoustic systems built on the D-Mitri digital audio platform. The DVRAS module provides input channel and VRAS (Variable Room Acoustic System) processing for up to 16 microphones and 16 return channels in one zone of a Constellation system. The module also contains SSD storage for measurement data and audio files used in system verification. D-Mitri is a sophisticated digital audio platform which is the basis for a family of powerful modules aimed at providing comprehensive audio processing, matrix mixing and routing for a variety of professional audio applications, including theatrical and spectacle productions, theme parks, and active acoustics. D-Mitri systems feature an extremely flexible and highly programmable control scheme that can be customized by the user via the Python scripting language and Open Sound Control real-time protocol (both open-source tools) to accomplish even the most complex tasks. D-Mitri modules communicate using the Ethernet/AVB standard, which provides guaranteed QoS (quality of service) and very low-latency. Selections of D-Mitri modules can be assembled to provide nearly any configuration of digital or analog inputs and outputs and channels of processing. Constellation electroacoustic architecture is a highly integrated hardware/software system built on D-Mitri that combines the natural acoustics of a space with powerful technology to create acoustics with natural characteristics, the aural qualities of the world's best rooms, and broad flexibility. The DVRAS module is intended exclusively for use in D-Mitri Constellation systems and executes the high-quality processing algorithms used in electroacoustic architecture. It additionally supplies equalization, dynamics processing, and delay for each input channel. The DVRAS module sends and receives all audio over D-Mitri's AVB-enabled Ethernet network. The DVRAS has two additional redundant Ethernet ports for connecting to a separate control network, to receive communication from CueStation software or an external hardware controller. -Provides high-quality VRAS processing for up to 16 input and 16 output channels in a D-Mitri Constellation system. -Supplies channel processing for each input. -VRAS processing controlled by CueStation software. -Processes streams of up to 32 bits of resolution at a 96 kHz sample rate. -Sends and receives audio to and from D-Mitri’s Ethernet/AVB network. -Redundant control ports. -Additional redundant AVB port.
