CHAPTER 1: INTRODUCTION GALILEO GALAXY 816-AES3 The GALAXY 816-AES3 model provides 16 matrix outputs on eight AES3 digital outputs. It can be used to drive the standard GALAXY 408 and 816’s digital inputs or any other device that accepts 96 kHz AES digital audio signals. For more information on the GALAXY 816-AES3 and its differences from the standard GALAXY 816, see Appendix A, “Galileo GALAXY 816-AES3.”...
GALILEO GALAXY USER GUIDE SIM 3 SUPPORT ® The GALAXY can be connected directly to the SIM 3 audio analyzer, providing complete audio measurement capabilities for complex audio systems.
You can use the Compass control software to capture GALAXY settings. The settings are saved as project files or as individual settings files on the host computer and can be later restored back into the GALAXY. Contact Meyer Sound Technical Support for more information or help with the Compass Control Software: ■...
CHAPTER 2: FEATURES AND FUNCTIONS GALAXY FRONT PANEL GALAXY front panels The GALAXY front panel provides basic information and mute control of the loudspeaker manage- ment system. It shows Input level metering for all inputs, and status and control for all outputs. The GALAXY front panel is divided into three sections: ■...

Make sure the AC power cable has the appropriate power plug on the other end for the area in which you will operate the GALAXY. NOTE: The GALAXY incorporates Meyer Sound’s Intelligent AC power supply, which automatically adjusts to any line voltage worldwide, and provides soft turn-on and transient protection.
Page 23
■ Analog Output Connectors (1–16): Sixteen XLR-3M connectors route audio to Meyer Sound self-powered loudspeakers, or to amplifier channels driving passive systems. All signal routing and processing stored in the GALAXY devices settings and saved Project file is applied to these outputs.
CHAPTER 2: FEATURES AND FUNCTIONS DIGITAL LATENCY The GALAXY features fixed latency across all output channels, regardless of the processing applied. GALAXY AES3 inputs have sample rate converters which support a wide range of sample rates. See Table 1 below for latency based on sample rate. To provide the highest level of audio precision and dynamic range with the lowest latency, GALAXY audio processing uti- lizes variable length integers with up to 64 bits of resolution.
GALILEO GALAXY USER GUIDE INPUT SAMPLE RATES The GALAXY accepts a wide range of sample rates for both AVB and AES inputs. (see Table 2). To use AVB inputs, you must set the System Clock to AVB. Table 2: Accepted Input sample rates and bit depth based on format Format Input Sample Rates Accepted (Hz) Bit Depth...
GALILEO GALAXY USER GUIDE CHAPTER 3: CONNECTING THE GALAXY POWER CONNECTOR ® The GALAXY uses a locking PowerCon connector to provide AC voltage to the unit. Its internal switching power supply has a safety-agency-rated operating range of 100–264 V AC, 50/60 Hz. Locking PowerCon connector for AC power Electrical Safety Issues! Pay close attention to these important electrical and safety issues:...
CHAPTER 3: CONNECTING THE GALAXY REMOTE COMPUTER CONNECTION The GALAXY’s RJ-45 port connects to a standard computer Ethernet port with Gigabit-capable network cables. A Mac or Windows-based computer running the Compass software uses the Ethernet connection to control the unit remotely. Bi-directional communication between the GALAXY device and the Compass software allows the user to change settings on either device and stay in sync.
+26 dBu (15.5 V rms) or +16 dBu (7.75 V rms) These output level settings determine the clipping levels and provide the flexibility to drive all Meyer Sound self-powered products. In addition, inputs A, C, E, and H can be configured as Analog or AES. The GALAXY front panel input meters indicate analog and digital signal levels.
Page 30
CHAPTER 3: CONNECTING THE GALAXY Digital Inputs: AES3 AES3 digital source signals can be connected to the XLR-3F connectors labeled A, C, E, and H on the GALAXY rear panel. Standard AES3 digital audio signals at sample rates from 20–216 kHz are supported.
Page 31
GALILEO GALAXY USER GUIDE Digital Inputs: AVB Network digital source signals can be connected to the AVB/Network port connectors (labeled 1 and 2) on the GALAXY rear panel. Standard AM824 eight-channel AVB streams are supported (24 bit, 96 kHz). NOTE: The Compass software can set the Input Channel Type to one input type (Settings >...
40 Gb/s. A 1 GB/s or better Ethernet link will work for AVB transmission using properly configured hardware: Copper, multi-mode fiber, single-mode fiber, etc. Fiber transceiver format must match the cable being used. Meyer Sound recommends AVB compliant (preferably AVNU certified) network switches.
OUTPUT CONNECTORS (TO LOUDSPEAKERS/ARRAYS) GALAXY Output connectors The GALAXY includes 16 XLR-3M output connectors with 24-bit/96 kHz D/A converters. The GALAXY can easily drive Meyer Sound self-powered loudspeakers to full output at all frequencies, even over lengthy cable runs. NOTE: The adjustable output range provides two level output settings to drive Meyer Sound self-powered products.
Its presence is indicated with the SIM 3 LED on the GALAXY front panel. The SIM 3 also appears in the Compass software (Settings > SIM 3). For more information regarding SIM 3 compatibility, please contact Meyer Sound Technical Support: ■...
