CHAPTER 1: INTRODUCTION
GALILEO™ PRODUCT OVERVIEW
The Galileo loudspeaker management system is a complete hardware and software solution
with all the necessary tools for driving and aligning sound reinforcement systems with multiple
zones. The system consists of:
■ Galileo 616: A fully digital matrix processor with six inputs and 16 outputs.
Designed as the perfect complement to Meyer Sound’s self-powered loudspeakers,
Galileo includes array correction for M Series array products, presets for Meyer Sound
systems of various sizes and types, and digital implementations of technologies used in
Meyer Sound’s groundbreaking analog processors and line drivers. The system includes a
wide selection of bandpass and parametric EQs, delay and gain adjustments, air absorption compensation, and other signal processing.
Galileo’s Composite EQ architecture offers the most extensive equalization of any current
loudspeaker management system. By providing both CP-10 complementary phase parametric equalization and TruShaping™ low-order shaping equalization, Composite EQ provides the right tools for addressing both acoustic anomalies and subjective sonic
requirements. The Galileo 616 features full digital operation with fixed latency across all
output channels regardless of the processing applied (see Table 1). All internal processing
is performed at 96 kHz with a 32-bit floating point vector processor.
Table 1: Internal Digital Audio Input Latency
Sample Rate Input (kHz) Measured Latency (ms)
32.0 4.15
44.1 3.52
48.0 3.37
96.0 2.60
192.0 2.43
Analog audio input latency: 1.53 ms
*Test conditions were factory default settings: All input and output EQ and TruShaping™ filters enabled but
set to flat response, no other filtering enabled.
For maximum flexibility, the Galileo 616 can be controlled from its front panel, using its
navigation buttons and LCD screen, or from the Compass control software.

GALILEO 616 USER GUIDE
■ Compass™ control software: Provides comprehensive control of the Galileo 616 through
a graphical user interface running on a remote computer.
Compass is the primary method of operating the Galileo loudspeaker management system. The software enables easy access to all Galileo features and even provides control of
multiple units. Compass includes a context help system, full copy and paste of all settings
and groups of settings, and multiple levels of undo. The tabbed interface can be scaled to
any display resolution and the colors can be configured for either day or night. Windows
and Mac OS X versions have the same user interface so that switching between platforms
is completely transparent.
A sophisticated channel linking system allows multiple input and outputs, even on multiple
Galileo 616s, to be linked so that parameter changes can be applied to all linked channels.
Relative gain mode allows gain changes to linked channels while retaining gain differences
between linked channels.
The EQ Plotter window includes an overlay display of the applied CP-10 and TruShaping
equalization, for both amplitude and phase, in a single editable window. Equalization
parameters can be edited directly by simply dragging EQ points in the display, or by entering values numerically for greater precision.
SIM® 3 Support
The Galileo 616 can be directly connected to the SIM® 3 audio analyzer, providing complete
audio measurement capabilities for complex audio systems.

CHAPTER 2: GALILEO 616 FEATURES AND FUNCTIONS
GALILEO 616 PROJECTS
A Galileo 616 project is the organizational structure in which one or more snapshots — full
configurations for all parameters and system settings — are kept. The Galileo 616 holds only
one project file at a time and allows the user to scroll through and load any snapshots contained in the project.
The Compass control software, running on a computer, does not have its own memory for
system settings and parameters, and just reads what it is connected to. So when Compass is
connected to a Galileo 616, it reads and displays the project file and the current active snapshot that is 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 Galileo 616
replaces whatever project file is currently in the Galileo 616.
CAUTION: Opening a project file in the Compass control software when the
computer is connected to a Galileo 616 will overwrite the project, and its snapshots, residing in the Galileo 616 (if the Overwrite option is selected when opening the
project). To merge snapshots from another project file into the current project in a
Galileo 616, use the Merge Project option on the Open Project dialog box (click More
for this option to appear).
TIP: You can use the Compass control software to read and save the
Galileo 616’s project file (and the snapshots it contains) as a backup procedure.
This file can be saved in the computer (or to a network server, CD, or other storage
medium) and later reloaded via Compass to the Galileo.

Galileo 616 Rear Panel
The rear panel provides connections for six inputs and 16 outputs, plus connections to the
SIM 3 analyzer or additional Galileo units. An Ethernet connector allows connection to a
remote computer running the Compass software.
■ PowerCon AC Power Connector: This locking connector mates with the provided AC
power cable.
CAUTION: Make sure that you select the correct power plug for the AC power in
the area in which the Galileo 616 is used.
NOTE: The Galileo 616 incorporates Meyer Sound’s Intelligent AC power supply,
which automatically adjusts for any line voltage worldwide, and provides both
soft turn-on and transient protection.
■ Ethernet Connector: This RJ-45 connector is used with a shielded CAT-5e cable (recom-
mended) or better Ethernet data cable to connect the Galileo 616 to an Ethernet network,
allowing control of Galileo from a computer running the Compass control software.
■ Analog / AES Input Connectors: The upper three XLR-3F input connectors, highlighted in
blue and labeled A, C, and E, accept either a standard line-level analog signal or an AES
two-channel digital signal.
17
CHAPTER 2: GALILEO 616 FEATURES AND FUNCTIONS
NOTE: Select whether each of these connectors will operate in the analog or the
AES two-channel digital mode on the System Settings page from the Galileo 616
front panel or the Compass software. This selection may be made individually for each
of these three connectors.
■ Analog Input Connectors: The lower three XLR-3F input connectors, labeled B, D, and F,
accept standard line-level audio only. These connectors are paired with the Analog/AES
connectors A, C, and E — typically used for the second analog channel of a left/right twochannel signal. When one of the upper connectors is set to AES mode, the connector
below it is disabled and will not accept an audio signal. For example, if Inputs A and C are
set for AES mode, then Inputs B and D are disabled. In this example, inputs E and F may
still be used with analog signals
■ Output Connectors: These sixteen XLR-3M connectors connect to Meyer Sound self-
powered loudspeakers, or to power amplifier channels driving passive loudspeaker systems. The signal routing and processing internal to the Galileo 616 is applied to the output
of these connectors.
■ SIM 3 Bus Connectors: This pair of connectors provides connection to the SIM 3 audio
analyzer as well as loop-through to additional Galileo 616’s or SIM-3088 line switchers,
when Galileo’s connections are being used as measurement points. These connectors are
labeled “Connect to SIM 3022 or 3088 only.”

GALILEO 616 USER GUIDE
INPUT CONNECTORS (FROM CONSOLE)
Galileo 616 Input Connectors
Analog Inputs
Connections from analog sources, including analog mixing consoles, will be made via the six
XLR-3F connectors labeled A through F on the left side of the rear panel. The six analog inputs
are electronically balanced, and feed state-of-the-art A/D converters operating at 24-bit resolution at a 96 kHz sample rate. Within the System Settings window of the Compass control
software, the Input Channel Types will be set to Analog (the default setting). These connectors
will accept signal levels up to +26 dBu at the default setting, and can also be set to +20 dBu.
NOTE: The adjustable output range provides two level output settings to drive
Meyer Sound self-powered products. The +20 dBu output range setting lowers
the overall noise floor by nearly 6 dB. However, this setting makes the Galileo output
signal more vulnerable to defects in the overall grounding system. Thus the actual
improvement attained depends on the quality of the grounding between components.
For this reason the default setting has been changed to +26 dBu. In either setting, the
digital gain will compensate for either analog output gain so that the overall system
output level set in the Galileo will remain the same.
