Galileo® GALAXY™ 816 Network Platform

The Galileo GALAXY™ 816 Network Processor is a sophisticated
loudspeaker management tool for controlling all Meyer speaker
types. The GALAXY loudspeaker processor harnesses open‑source
AVB technology to extend a new level of audio control in driving
and aligning loudspeaker systems with multiple zones. It provides
a powerful tool set for corrective equalization (EQ) and creative
fine‑tuning for a full range of applications from touring to cinema.

Users can readily program the GALAXY processor using Compass
software running on a host computer or via the Compass Go
application for the iPad. Compass control software includes
custom‑designed settings to integrate families together, as well
as for each family of speakers. For example, the Delay Integration
feature matches the phase characteristics between Meyer speaker
families to ensure the most coherent summation.

The GALAXY audio processing sample rate is 96 kHz; A/D and D/A
conversion are 96 kHz/24bits; the AVB streams are 24bits/96kHz.
GALAXY satisfies the Avnu Alliance certification for network
transmission, timing, and synchronization.

Processing tools for inputs and outputs include U‑Shaping and
parametric EQs, and delay. Output processing also includes
All Pass filters, polarity reversal, atmospheric correction, and

Low‑MidBeam control.

The built‑in summing and delay matrices allow a user to easily
assign gain and delay values, respectively, at each cross point.
This capability greatly facilitates using one loudspeaker to satisfy
multiple purposes.

Front panel controls let a user intuitively and quickly operate the
GALAXY 816 processor without a computer during live use.

The rear panel includes two SIM bus ports for direct connection to
Meyer Sound’s SIM® 3 audio analyzer, allowing the GALAXY816
processor to function as a line switcher for the analyzer. With this
capability, a user can take measurements from any selection of
GALAXY inputs and outputs without patching beyond a single
connection to the analyzer.

The GALAXY 816 has the following I/O:

• Inputs A‑H can receive analog, AES3, or AVB signals

• Outputs 1‑16 can be analog or AVB signals

The GALAXY 408 and GALAXY 816‑AES3 processors have the
same audio processing capability with different I/O. See their data
sheets for comparison.

COMPASS SOFTWARE

The Compass control software provides comprehensive control of the GALAXY processor from an intuitive graphical user interface
hosted on a Mac or Windows‑based computer. Compass software allows the user to control all features on multiple units.

Combining the key functionalities of the Compass software and the simplicity and mobility of the iPad, the Compass Go application
makes system setup and tuning easier and more intuitive. Download the free app from the Apple App Store, and connect it to Galileo,
Galileo Callisto, and Galileo GALAXY processors on the same Wi‑Fi network.
