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 absorp-

tion 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 para-

metric equalization and TruShaping™ low-order shaping equalization, Composite EQ pro-

vides 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.

*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.

■ 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 sys-

tem. 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 enter-

ing 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 con-

tained 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 snap-

shot 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 snap-

shots, 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 FRONT PANEL

The front panel of the Galileo 616 provides access to all of the powerful features of the loud-

speaker management system. Input level metering is shown for all inputs, as well as status

and control of all outputs. The large LCD screen provides access to all of the EQ, gain, delay,

and other settings available for both inputs and outputs. A set of cursor buttons provides nav-

igation throughout the screen, and Enter, Cancel, and Menu buttons give selection control. In

addition, three rotary encoders (knobs) allow the user to adjust the center frequency, band-

width, and boost or cut of the equalization points, as well as control other system parameters.

The Galileo 616 front panel is divided into the following three sections:

■ Inputs

■ Outputs

■ Navigation

Front Panel Input Section

■ Input Level Meters: Multi-segment LED ladders for each input, with the green LED range

beginning at approximately –80 dB below clipping, yellow LED range lighting a few dB

below clipping, and top red LED indicating clipping of the A/D converter at +26 dBu

(15.5 V rms; this range can also be set on the System Settings page to +20 dBu /

7.75 V rms).

■ Input Select Buttons / LEDs: One for each input channel, to select the channel for various

actions; as many channels as desired can be selected at any time. The accompanying blue

LED lights when the channel is selected. Selecting a channel in the Compass software also

activates the button and the associated LED.

■ Input Mute Buttons: One for each input channel, allowing the channel to be muted or

unmuted. Selecting Mute for a channel in the Compass software also activates the button.

■ Signal / Clip LEDs: One for each output channel. For levels between around –85 dB

below clipping to approximately –5 dB below, the LEDs light green with intensity corre-

sponding to signal level. For levels from around –5 dB below clipping to the clipping level,

they light amber. The LED turns red if the signal level is at clipping, which occurs at levels

at or above +26 dBu (15.5 V rms; this range can also be set on the System Settings page

to +20 dBu / 7.75 V rms.)

NOTE: The default and recommended output setting is +26 dBu.

■ Output Select Buttons / LEDs: One for each output channel, to select the channel for

various actions; as many channels as desired can be selected at any time. The accompa-

nying blue LED lights when the channel is selected. Selecting a channel in the Compass

software also activates the button and the associated LED.

■ Output Mute Buttons: One for each output channel, allowing the channel to be muted or

■ Settings Knobs: Three rotary encoders (with push switches) are used to change parame-

ter values for the various settings available on the Galileo, based on what is currently

selected on the LCD screen. For example, when setting Parametric EQ points, the Blue

knob adjusts the center frequency, the Green knob adjusts the bandwidth (Q), and the Red

knob adjusts the cut/boost level.

■ Ethernet LED: When this LED is lit, it indicates that the Galileo 616 is connected to the

Compass control software running on an external computer via the rear panel RJ-45 con-

nector. Remote control of the Galileo 616 is accomplished with this connection.

■ SIM 3 LED: When this LED is flashing, it indicates the Galileo 616 is communicating with a

SIM-3022 audio analyzer on its line switcher bus, either directly or daisy-chained from a

SIM-3088 line-level switcher.

NOTE: The SIM 3 Address for the Galileo 616 must be set to a number between

10 and 14, either in the System Settings menu onboard Galileo or in the Com-

pass software. It will then be available in the Switcher section of SIM 3 under tabs 10

through 14, and can be configured to perform audio measurements.

■ Power Switch / LED: Pressing this switch turns on the Galileo 616; press and hold the

switch for approximately two seconds to turn off.

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.

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 two-

channel 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 sys-

tems. 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.”

CHAPTER 3: CONNECTING THE GALILEO 616

POWER CONNECTOR

The Galileo 616 uses a locking PowerCon

®

connector to provide AC voltage to the unit. Its

internal switching power supply accepts voltages from 90 to 264 V AC, 50/60 Hz.

Electrical Safety Issues!

Pay close attention to these important electrical and safety issues:

■ Make sure you to use the correct power plug for the AC power in the area in which you will

operate the Galileo 616.

■ Always use a grounded outlet and plug.

CAUTION: To comply with EMC standards, only operate this device with the

supplied shielded power cord.

REMOTE COMPUTER CONNECTION

The Galileo 616’s RJ-45 port connects to a standard computer Ethernet port with shielded

Cat-5e cables. The Ethernet connection allows the unit to be controlled remotely from a Mac

or Windows computer running the Compass control software. Bi-directional communication

ensures that the current settings, whether changed from the Galileo 616 front panel or from

the Compass software, are always in sync.

NOTE: When connecting the Galileo 616 to a computer through a router, make

sure the router’s IP address is appropriately configured (192.168.0.1).
