CHAPTER 1: INTRODUCTION
The Galileo GALAXY features full digital operation with fixed latency across all output channels,
regardless of applied processing. To provide the highest level of audio precision and dynamic
range while minimizing latency, audio processing in the GALAXY utilizes high precision variable length integers with 64-bit resolution.
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
COMPASS CONTROL SOFTWARE
The Compass control software provides comprehensive control of the Galileo GALAXY from
an intuitive graphical user interface on a Mac® or Windows®-based computer. Compass software lets you control all features on multiple units.
EQ Plots in the Compass Control software
The Overview tab displays a summary of all GALAXY channels with signal flow. Inputs and
outputs can be labeled and conveniently grouped for simultaneous editing. The Input Processing and Output Processing tabs provide access to all DSP settings. Equalization parameters can be edited with numeric entry or by dragging frequency bands. Multiple EQ layers can
be viewed as a composite plot of equalization curves.
SIM 3 SUPPORT
The GALAXY can be connected directly to the SIM® 3 audio analyzer, providing complete
audio measurement capabilities for complex audio systems (see page 43).

GALILEO GALAXY USER GUIDE
CHAPTER 2: FEATURES AND FUNCTIONS
GALAXY PROJECTS AND SETTINGS
GALAXY project files are saved by the Compass control software to the host computer.
Project files contain the full configuration of parameters, system settings, and snapshots
stored in the GALAXY. When a GALAXY is connected to the host computer, the Compass
control software reads and displays the configuration currently residing in the GALAXY.
The Compass control software does not have its own memory for system settings and parameters; it just reads what it is connected to. When Compass is connected to a GALAXY, it reads
and displays the parameters and settings of a project file and the current active snapshot and
snapshot library contained in the unit’s memory. However, loading another project file (stored
on the computer) into the Compass control software when it is connected to a GALAXY
replaces the current snapshot and, if selected, the device settings currently loaded in the
GALAXY.
CAUTION: Opening a project file in the Compass control software when the
computer is connected to a GALAXY overwrites all stored snapshots and current
device settings residing in the GALAXY (if Load Device Settings is selected when
opening the project). To merge snapshots from another project file into the current
library of snapshots in a GALAXY, use the Merge Project option from the Project tab
(click the More>> button for this option to appear).
!
TIP: 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 (see page 11).

CHAPTER 2: FEATURES AND FUNCTIONS
DELAY INTEGRATION
Systems comprising multiple loudspeaker types with different phase responses placed in
close proximity to one another can result in undesired summation or cancellation in the lowmid frequencies. As Meyer Sound improves the native phase response of its loudspeakers,
the Delay integration feature quickly matches the phase responses of mixed loudspeaker
products used in a given system.
Delay Integration is available on every GALAXY output.
Click the product button to open the
Delay Integration Browser
Opening the Delay Integration browser
18
GALILEO GALAXY USER GUIDE
To use Delay Integration:
1. Click the product button from the Output Processing or Overview tab.
The Delay Integration browser opens.
Select the Meyer Sound product
Select the desired
phase curve frequency
Delay Integration browser
2. Select the Meyer Sound loudspeaker model that corresponds to that GALAXY output.
3. Choose the lowest phase curve common to all products in a given system.
Each GALAXY output channel can be set to one of three phase curve frequencies:
pc55-70, pc100, or pc125.
NOTE: Not all products will have all three options available.
19
CHAPTER 2: FEATURES AND FUNCTIONS
The native phase curves exhibited by Meyer Sound products can be differentiated by the
lowest frequency at which each product deviates by 180° of relative phase. Delay integration
uses the concept of phase curve families shared by different products: For example, the LYON
and LEOPARD’s low-mid phase response is 180° at 55 Hz (pc55-70); the LEO-M and UPQ's
low-mid phase response is 180° at 100 Hz (pc100).
First frequency with a relative phase
deviation of 180° at 55 Hz
LEOPARD free-field phase response showing the first frequency with a relative phase deviation of 180° at 55 Hz
First frequency with a relative phase
deviation of 180° at 100 Hz
UPQ-1P free-field phase response showing the first frequency with a relative phase deviation of 180° at 100 Hz
20
GALILEO GALAXY USER GUIDE
Delay Integration Example
Delay integration is especially appropriate when applied to loudspeakers that are not in the
same phase curve family.
To accomplish Delay Integration for LEOPARD with UPQ-1P:
1. Enable Delay Integration on both the LEOPARD and UPQ-1P outputs.
2. Select pc100 for both outputs.
3. Use pure delay to time align the two loudspeakers where they are equal in level.
4. Select the Overview tab to verify all loudspeaker system outputs are set to the same pc
value.
Technical Notes
■
If your system contains just one type of loudspeaker, do not use Delay Integration.
■
For best results, apply the lowest common phase curve value to different loudspeaker
models that are in close physical proximity to each other.
■
For UltraSeries models, pc100 is the lowest common value.
■
Although the M Series phase response is 180° at 350 Hz, it can be improved by using
pc125 when used in close proximity to other Meyer loudspeakers.
■
When Delay Integration is applied to subwoofer outputs, the phase slope is optimized to
align with the mid-high loudspeakers using the same pc setting.
■
The changes in phase response caused by Delay Integration are not displayed in the Compass software, but they can be measured using the transfer function in SIM.
■
If you enable a pc frequency for a Meyer Sound loudspeaker that natively exhibits that pc
frequency, nothing will change for that output. For example: LEO-M is natively pc100. If
Delay Integration is enabled for that output and set to pc100, no measurable change
would occur.

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 utilizes variable length integers with up to 64 bits of resolution.
The analog latency for GALAXY (AD/DA) is fixed at 596.8 microseconds.

INPUT CONNECTORS
Analog Inputs
Analog source signals, including those from analog mixing consoles, are connected to the
XLR-3F connectors (labeled A – H) on the left side of the GALAXY rear panel. These eight
balanced analog inputs feed state-of-the-art A/D converters (24-bit, 96 kHz sample rate). The
Input Voltage Range can be set in the Compass software (Settings > Input and Output) to
either +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.
NOTE: The +16 dBu output setting lowers the overall noise floor by nearly 10 dB.
GALAXY Input Connectors
33
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. The input meters on the GALAXY front panel indicate levels for both analog
and digital signals
NOTE: The Input Channel Types can be set to Analog or AES in the Compass
software (Settings > Input and Output). Because AES signals carry two digital
audio channels, the second connector in the pair is disabled when AES is selected.

GALILEO GALAXY USER GUIDE
Digital Inputs: AVB - Internal Controller Mode
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, 48/96 kHz). There are two modes: Internal and External. Internal Mode is specific to
Meyer Sound GALAXY devices.
NOTE: The Compass software can set the Input Channel Type to one input type
(Settings > Input and Output). To see talker streams and stream channels from a
group of GALAXY devices, those GALAXY devices must be in the same Device Group.
Compass Input and Output Settings, AVB Input Channel selection browser (Internal Controller)
Outputs from available GALAXY devices will populate the AVB Browser when that device is
selected from the available Devices List. The Group can be selected from the Group selection
menu. You can connect and disconnect configurations.

GALILEO GALAXY USER GUIDE
AVB STREAMS AND CONTROLLERS
An AVB Stream functions much like an analog multi-cable. Each stream can vary in number of
channels and format, similar to AES3 and standard analog multi-cables. The difference is that
many audio streams can flow down a single Ethernet cable.
Unlike traditional multi-cables, AVB streams do not stay connected when the audio devices
are turned off. An AVB software controller creates and maintains these connections running
on a computer attached to the network or inside one of the audio devices being controlled. An
AVB controller in the audio device will maintain persistent connections and remake connections after power cycle or other interruptions like unplugging an Ethernet link.
Each GALAXY has a built-in AVB controller. If GALAXY B’s inputs are subscribed to GALAXY
A’s outputs for the first time using Compass software, GALAXY B’s AVB controller will attempt
to remake that connection in case of any interruption.
GALAXY AVB streams are 24-bit/96 kHz 8-channel AM824 packet format. AM824 supports
the transport of multi-channel 24-bit linear audio. Since GALAXY inputs can choose up to
eight individual AVB channels from up to eight different streams, it is possible to send up to 8
eight-channel streams (64 channels) into the unit. However, only eight of them are available for
input processing. There are 24 additional AVB inputs available into the Gain, Delay, and
Summing matrices without input processing (see figure below).
37
CHAPTER 3: CONNECTING THE GALAXY
Expanded Summing Matrix Inputs in Compass Desktop
GALAXY outputs use two AM824 formatted streams: Outputs 1–8 are available in the first 8channel stream, outputs 9–16 are available in the second 8-channel stream. If no units have
subscribed to these streams, the GALAXY will stop transmitting altogether. The analog outputs are always active.
The following shows the number of streams/audio channels possible on different kinds of
Ethernet links (see note below):
■
23 eight-channel GALAXY formatted streams can be safely transmitted using a 1 Gb/s
link at 75% Bandwidth Usage (184 channels)
■
238 eight-channel GALAXY formatted streams can be safely transmitted using a 10 Gb/s
link at 75% Bandwidth Usage (1904 channels)
■
954 eight-channel GALAXY formatted streams can be safely transmitted using a 40 Gb/s
link at 75% Bandwidth Usage (7632 channels)
38
GALILEO GALAXY USER GUIDE
NOTE: An Ethernet link is the either a CAT5e or better 8P8C (RJ45), or a fiber
cable with the hardware ports either cable type is attached to. There are three
common link varieties: 1, 10, and 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 (Avnu-certified) network switches.

GALAXY AVB connection example
The GALAXY includes two network ports for both AVB and control connections. Either port
can be used to make single connections to the network as shown in the figure above. These
ports take advantage of multiple industry-standard networking protocols to offer an automatic
fail-over procedure:
1. GALAXY uses one of its two available ports during normal operation. When connectivity is
lost on the active port, GALAXY performs a network connection verification process before
switching to the other port.
2. Once on the other port, GALAXY relies on internal switching protocols to reroute control
and AVB to the now active fail-over port.
3. GALAXY will lose audio for up to 45 seconds while it renegotiates its AVB connections.
Control is restored when the new connection is established.

GALAXY AVB Redundant Network connection example
This figure above shows a network taking full advantage of the AVB switch spanning tree protocol
along with GALAXY fail-over capability. Any single link in the system could be compromised or
unplugged and the audio will take an alternate route and remake the connections to continue
from device to device.
This style of fail-over does not happen instantaneously. It depends on the network setup and
whether the network fault occurs at the switch or at the GALAXY device. Since a different
series of events can occur in each case, it could take up to 45 seconds to restore the connections (including clock synchronization).
NOTE: Please consider using analog signal transmission lines as a failsafe for
digital audio network connections.

CHAPTER 3: CONNECTING THE GALAXY
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. In the Compass software (Settings>Input
and Output), you can set the Voltage Range for all inputs and outputs to either
+26 dBu (15.5 V rms) or +16 dBu (7.75 V rms), which determines the clipping levels.
The +16 dBu output setting lowers the overall noise floor by nearly 10 dB.
NOTE: The GALAXY 816-AES3 provides 16 matrix outputs on eight AES3 digital
outputs. For more information, see Appendix A, “Galileo GALAXY 816-AES3.”

SIM3 Connectors
The GALAXY rear panel includes a bus for direct connection to the SIM 3 audio analyzer. The
GALAXY can then act as a line switcher for the analyzer, and measure across any selection of
inputs and outputs without additional patching.
GALAXY SIM 3 connectors: top is for SIM3, bottom is looping connector
The default bus address for the GALAXY is 10 and the available range is 0–14. The SIM 3 is
auto-detected when connected. 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).
A second SIM 3 (looping) connector (labeled CONNECT TO SIM3 BUS in figure above) is
included on the GALAXY rear panel. It can be used to connect to an additional GALAXY or to
a SIM-3088 line-level switcher.
NOTE: The GALAXY 408 does not have the second SIM 3 looping connector.
CAUTION: If a SIM-3088 switcher is connected to the SIM 3 looping connector,
you must use a SIM-3004 remote power supply. Make sure the power supply
connector is marked Connect to 3022 Analyzer Only before making this connection.

APPENDIX C: GALAXY MESSAGE CODE GLOSSARY
Message codes appear on the GALAXY front panel and are also stored in the Compass log.
The front panel displays a summary of the GALAXY message with its numeric code. The
Compass log contains the full description of the GALAXY message and numeric code, which
can be useful for Meyer Sound Technical Support (see page 11).
GALAXY messages occur in one of three categories:
■
Info: A parameter or connection changed, but there is no error in operation.
■
Warn: A brown-colored message warns that a parameter is out of its normal operating
range, but the device continues to function.
■
Critical: A red-colored message states a critical error, and the device stops functioning.
CAUTION: If a critical error causes the front panel text to appear degraded or
hazy, call Meyer Sound Technical Support (see page 11) and stop using the
device, even if it continues to function.
!
Hardware Control Error codes start with “3” and are followed by a second number that defines
a specific condition code:
■
Message Code 3/4: Device temperature is above or below normal operating range.
■
Message Code 3/5: Monitored voltage is above or below normal operating range.
■
Message Code 3/6: Fan Speed (tachometer) is above or below normal operating range.
■
Message Code 3/7: Fan controller has failed.
