Meyer Sound introduces the NADIA platform for future Constellation installations

Designed to power future installations of Constellation, Meyer Sound has developed the NADIA integrated network-based digital audio processing and distribution platform. 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 “without performance compromises”.

Comprising three hardware modules, the NADIA platform supports up to 96 inputs for Constellation acoustic processing in addition to 128 independent program audio inputs. 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 and all the processing is at 96kHz/64-bit floating point resolution. For analogue input, the NADIA platform offers the NADIA-AI12 input module, providing 12 channels of analogue input with a preamp on each channel to accommodate Constellation microphones.

For analogue outputs, the NADIA-AO16 provides 16 channels of analogue line level output. NADIA outputs can be routed directly via the network to Milan endpoint loudspeakers such as Ultra-X20 series speakers and USW-112P subwoofers. In an active acoustic system, which requires discrete output channels for many loudspeakers, this eliminates separate output modules to reduce rack space requirements.

Each NADIA-CP module hosts up to 12 VRAS (Variable Room Acoustic System) processors, enabling the configuration of up to 12 discrete acoustical zones in a single unit. A standard licence is available for all 12 VRAS processors, and a lower cost lite version can be applied for three processors. In comparison to the D-Mitri processor solution, Constellation systems based on NADIA benefit from reductions in both rack space and overall costs.

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 multichannel spatial audio processing backed up by a new signal path featuring two matrix sections. Along with an input matrix addressed by Spacemap Go, new levels of granularity and control are available with a separate output matrix. NADIA can also connect to Galileo Galaxy 816 and 408 processors, mixing consoles equipped with direct Milan outputs, multichannel computer playback from AVB-compatible Apple or Windows computers and Avnu-certified format converters for other digital audio networks.

Backed up by the power of CueStation 8 as a calibration and programming tool, an updated control interface enhances how users work with Constellation's active acoustics in their venue. When implemented, Spacemap Go NADIA provides a separate user interface for controlling dynamic spatial sound in integrated PA systems. NADIA systems also can be controlled by OSC commands to enable integration with third-party protocols when incorporating NADIA-based systems into wider AV and building control systems.
