Galileo® 616 : Loudspeaker Management System
The Galileo loudspeaker management system
is an elegant hardware and software solution
for driving and aligning multi-zone loudspeaker systems. The 2-space, rack-mount
Galileo 616 includes six inputs, 16 outputs, and
a fully digital matrix processor. The Compass®
control software provides comprehensive
control of all parameters from a Mac® or
Windows®-based computer. The Galileo 616 is
also fully programmable from its front panel
for maximum flexibility.
Designed as the perfect complement to
Meyer Sound’s self-powered loudspeakers,
the Galileo loudspeaker management system
includes array correction for M Series™ array
loudspeakers, atmospheric correction filters,
low- and high-pass filters for subwoofer
control, and configuration presets for Meyer
Sound loudspeaker systems of various types
and sizes.
The Galileo 616 offers an extensive
equalization architecture that includes
complementary phase parametric filtering
and TruShaping® low-order equalization on
both inputs and outputs. 31-band graphic
equalization is also available on inputs.
Equalization parameters are easily edited in
the Compass control software, with numeric
entry or by graphically dragging frequency
bands. Parameters can be adjusted while
viewing multiple layers of equalization in a
composite graphic plot to achieve the ideal
equalization curve. The Compass software’s
intuitive user interface is the culmination
of Meyer Sound’s extensive experience
optimizing complex loudspeaker systems.
The Galileo 616 features full digital
operation with fixed latency across all
output channels regardless of any applied
processing. It can also be connected directly
to the SIM® 3 audio analyzer, providing
complete measurement and control for
integrated audio systems.

Galileo 616 Hardware
The Galileo 616 features six analog inputs
with balanced XLR connectors and state-ofthe-art A/D converters operating at 24‑bit
resolution with a 96 kHz sample rate. The
inputs can be individually switched to operate
as stereo AES/EBU digital inputs, accepting
sample rates up to 96 kHz. Because internal
processing is performed at 96 kHz with 32‑bit
vector floating point, source signals with lower
sample rates are upsampled using advanced
hardware sample rate converters. The six input
channels can be configured in pairs to receive
a combination of analog and digital sources.
The 16 analog outputs feature balanced XLR
connectors with high-resolution 96 kHz,
24‑bit D/A converters, and a robust maximum
output level of +26 dBu, capable of driving
Meyer Sound self-powered loudspeakers to
full output, across all frequencies, over long
cable runs.
The Galileo 616 processor is built around a
monolithic, 1 GHz vector DSP architecture
with a direct DMA audio path to maximize
processing power and guarantee fixed lowlatency performance, no matter how much
processing is applied. High-quality algorithms
with 32-bit floating-point resolution and
96 kHz sample rates are used to deliver a large
assortment of processing.
The rear panel includes two SIM bus ports for
direct connection to Meyer Sound’s SIM 3 audio
analyzer, allowing the Galileo 616 to function
Galileo 616 Signal Flow
Inputs A-F
Galileo 616 Front and Rear Panels
as a line switcher for the analyzer so that
measurements can be taken from any selection
of Galileo inputs and outputs, without patching
beyond a single connection to the analyzer.
Front panel controls allow the Galileo 616 to be
operated intuitively and quickly during live use,
without a computer. Input levels are displayed
with 26-segment LED meters, while output
levels are indicated with variable-intensity,
bi-color clip LEDs. Inputs and outputs also
include illuminated mute and select buttons.
Internal Processing: 32-bit Vector Floating Point @ 96 Khz
Parameters are displayed on a 128 x 64 LCD and
can be accessed and edited with the navigation
buttons and high-resolution encoder knobs.
AC power is software-activated so that
accidental button-pushes won’t power
down the Galileo 616. A locking powerCON®
AC connector prevents unwanted power
disconnections. Front panel locking and
password protection are available to guard
against errant parameter changes.

Galileo 616 DSP
The Galileo 616 includes a powerful arsenal
of DSP for tuning and aligning Meyer Sound
loudspeaker systems. In addition to standard
DSP components like delay (up to 2 seconds),
gain, and polarity reversal, the Galileo 616
boasts an unprecedented architecture
of equalization and filtering capable of
addressing a range of acoustic anomalies
and subjective tailoring of system responses,
without introducing excessive shifts in phase
that degrade intelligibility and signal clarity.
TruShaping equalization, available on both
inputs and outputs, is comprised of four
first-order interactive filters configured
in a unique cascading topology that allows
bands to overlap, resulting in slopes as low
as 3 dB per octave, yielding extremely smooth
response curves with minimal phase shifts.
Because Meyer Sound loudspeaker systems
are optimized to produce flat frequency
and phase responses out of the box, the
TruShaping equalizer is a powerful tool
for adding warmth, presence, and other
subjective sonic qualities.
To address anomalies resulting from
loudspeakers interactions, or loudspeaker
interactions with acoustical environments,
complementary phase parametric filtering
is provided — 5 bands on inputs, 10 bands
on outputs. As a second-order filter, the
parametric filter is ideal for treating these
types of interaction artifacts.
For even more flexibility, a 31-band graphic
equalizer with a 20 Hz to 20 kHz frequency
span is available on each input.
The array correction filter reduces low and
low-mid frequency buildup common with line
arrays and curvilinear arrays. Simply specify
the M Series loudspeaker model, along with
the number of cabinets employed in the
array, and the Galileo 616 will use its stored
table of compensation parameters to adjust
for the array’s output.
The
atmospheric
correction
filter
compensates for high frequencies absorbed
when sound travels through the air over
long distances. By entering just a few
atmospheric settings — temperature,
relative humidity, distance, and altitude
— the system automatically calculates and
applies the appropriate filtering to correct
for the environmental conditions. The userdefined Atmospheric Gain Factor ensures
that sufficient headroom is available
for reinforcement systems that require
maximum output.
Also included are low- and high-pass filters
for subwoofer control.
Air Absorption Calculation (ANSI S1.26 - 1995)
DSP parameter settings are accessible
from the Galileo 616’s front panel, as well
as from the Compass control software.
Unique settings for multiple loudspeaker
configurations can be stored as presets and
recalled from the front panel or from the
host computer.
Compass Control Software
The
Compass
control
software
provides comprehensive control of
the Galileo 616 from an intuitive
graphical user interface. The software
enables easy access to all features
and even provides control of multiple
units. Compass runs on a Mac or
Windows-based computer.
The Galileo Map tab displays a
summary overview of all Galileo
channels complete with signal flow.
Inputs and outputs can be labeled and
conveniently grouped for gang edits.
Compass Control Software, EQ Plots
The Input Processing and Output
Processing tabs provide access
to all DSP settings. Equalization
parameters can be easily edited
with numeric entry or by graphically
dragging frequency bands. Multiple
layers of equalization can be viewed
for a composite graphic plot of
equalization curves.
