Galileo GALAXY Network Platform
The Galileo GALAXY Network Platforms contain audio processors that are sophisticated loudspeaker management tools offering comprehensive control of Meyer Sound loudspeaker systems. They provide powerful tool sets for corrective equalization and creative fine-tuning in fully networkable devices.
Note
For expediency in the following documentation, the Galileo GALAXY Network Platform is referred to as the “GALAXY processor” or where appropriate, by specific models such as “GALAXY 408 processor,” “GALAXY 816 processor,” and “GALAXY 816-AES3 processor.” Similarly, Compass Control Software is simply called “Compass” or “Compass Go.”
Powerful audio processing
GALAXY processors feature a 96 kHz audio processing sample rate and use 24-bit/96 kHz A/D and D/A converters. Input processing tools include gain, delay, 5-band parametric EQ, and 5-band U-Shaping EQ. Output processing tools include gain, delay, polarity reversal, 10-band parametric EQ, 5-band U-Shaping EQ, Low-Mid Beam Control (LMBC, see Low-Mid Beam Control (LMBC)), atmospheric correction (see Atmospheric correction), high- and low-pass filters, and all-pass filters. Built-in summing and delay matrices allow users to easily assign gain and delay values at each routing cross-point, enabling any single loudspeaker to serve as an output for multiple, independently processed input signals. The Product Integration feature combines the Delay Integration setting and Starting Points (saved channel settings) capability into a single dialog. This feature facilitates the optimization of systems to achieve the best possible performance (see ???).
The GALAXY 408 processor, the GALAXY 816 processor, and the GALAXY 816-AES3 processor have the same audio processing capability with different physical inputs and outputs. The GALAXY 816-AES3 processor also includes a BNC connection for external word clock input.
Extensive user control
Users can control any of the GALAXY processors using Compass Control Software (hosted on a Mac or PC) or via the Compass Go application for the iPad. Compass provides a complete toolkit for audio routing, system optimization, processing, and monitoring.
For units equipped with this component, the rear panel includes SIM 3 bus port(s) (one on the GALAXY 408 processor and two on both the GALAXY 816 processor and the GALAXY 816-AES3 processor) for direct connection to Meyer Sound’s SIM audio analyzer, allowing GALAXY processors to function as line switchers for the analyzer. With this capability, users can take measurements from any selection of GALAXY processor inputs and outputs without patching beyond a single connection to SIM.
Milan-certified network platform
Galileo GALAXY Network Platforms are Milan-certified, providing plug-and-play network interoperability with other Milan-certified devices via AVTP Audio Format (AAF) and Clock Reference Format (CRF) AVB streams. Milan is the application layer built onto the AVB network protocol that adds a framework of interoperability for professional AV devices. Milan certification denotes true network redundancy for AVB and control signals, as well as guaranteed on-time arrival and bandwidth reservations for AVB signals. For more information about networking the GALAXY processors, see the AVB Networking Guide.
