NADIA is an integrated, network-based digital audio processing and distribution platform that will power future installations of Constellation by Meyer Sound. When incorporated into new Constellation installations, in addition to the processing power and inputs reserved for active acoustics, Meyer Sound says NADIA also provides separate inputs, processing and matrix to enable Spacemap Go spatial sound with “no performance compromises for either function.”

Meyer Sound says the NADIA platform supports up to 96 inputs for Constellation acoustic processing and 128 independent program audio inputs and comprises three hardware modules. All NADIA-based systems require at least one NADIA-CP core processor that supports 128 outputs. Additional NADIA-CP modules can be added to increase the number of outputs in the extended system by 128 for each module. All communication to and from the NADIA-CP module is via a Milan-compatible AVB network. All processing is at 96 kHz/64-bit floating point resolution.

For analog input, Meyer Sound claims the NADIA platform offers an input module, NADIA-AI12, providing 12 channels of analog input with a preamp on each channel to accommodate Constellation microphones. For analog outputs, the NADIA-AO16 provides 16 channels of line-level analog production.

NADIA outputs can be routed directly via the network to Milan end-point loudspeakers such as ULTRA-X20 series compact loudspeakers and USW-112P subwoofers. According to Meyer Sound, an active acoustic system requires discrete output channels for a very large number of loudspeakers, this eliminates separate output modules and further reduces rack space and infrastructure requirements.

Meyer Sound says each NADIA-CP module hosts up to 12 VRAS (Variable Room Acoustic System) processors, configuring up to 12 discrete acoustical zones in a single unit. Two licenses are available for scalability and cost efficiency: standard for all 12 VRAS processors and lite for three processors at a “substantially lower licensing cost.” Compared to the prior D-Mitri processor solution, Meyer Sound says Constellation systems based on NADIA will benefit from reductions in both rack space and overall costs.

In addition to meeting the unique requirements of active acoustics, Meyer Sound says the processing power of NADIA allows for a separate partition dedicated to integrating sound reinforcement systems alongside Constellation. Many inputs are reserved exclusively for Constellation, with additional inputs available for multi-channel spatial audio processing backed up by a new signal path featuring two matrix sections. Along with an input matrix — addressed by Spacemap Go for easy, intuitive and creative spatial audio — users gain new levels of granularity and control with a separate output matrix.

For flexibility and system integration, NADIA can also connect to Galileo GALAXY 816 and 408 processors, as well as mixing consoles equipped with direct Milan outputs, multi-channel computer playback from AVB-compatible Apple or Windows computers, and Avnu-certified format converters for other digital audio networks.

Meyer Sound also claims the updated control interface enhances how users work with Constellation’s active acoustics in their venue. Spacemap Go NADIA provides a separate user interface for controlling dynamic spatial sound in integrated PA systems when implemented. All of this is backed up by the power of CueStation 8 as a calibration and programming tool.

OSC commands can also control NADIA systems to enable integration with third-party protocols when incorporating NADIA-based systems into wider AV and building control systems.
