Meyer Sound debuts NADIA platform

nadiaThe NADIA digital audio platform is currently being specified in all new Constellation acoustic system designs
USA - 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, NADIA also provides separate inputs, processing, and matrixing to enable Spacemap Go spatial sound with no performance compromises for either function.
“With NADIA, we have leveraged the latest advancements in DSP technology along with Milan-based AVB networking and combined them with Meyer Sound’s four decades of experience in dedicated signal processing for audio applications,” says Andy Davies, Meyer Sound senior product manager.
“The result is a uniquely powerful, scalable, and unified platform for signal processing and distribution. NADIA has been designed for our Constellation acoustic system, where the power of the new technology will allow more discrete zones for even higher resolution at substantially lower costs.”
The NADIA platform supports up to 96 inputs for Constellation acoustic processing as well as 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.
In addition to meeting the unique requirements of active acoustics, the processing power of NADIA allows for a separate partition dedicated to integrating sound reinforcement systems alongside Constellation. A large number of 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.
For flexibility and seamless system integration, NADIA also can 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.
An updated control interface enhances how users work with Constellation’s active acoustics in their venue. When implemented, Spacemap Go NADIA provides a separate, award-winning user interface for controlling dynamic spatial sound in integrated PA systems. All of this is backed up by the power of CueStation 8 as a calibration and programming tool.
Andy Davies adds: “Active acoustics and spatial audio have two very different sets of requirements. With Constellation, we are not simply adding reverb to a spatial sound system but rather creating a bespoke acoustic environment. Now with the power of NADIA, we can introduce spatial sound into that acoustic environment - without compromising either function - to create extraordinary audience experiences for venues of the future.”
