GALILEO LOUDSPEAKER MANAGEMENT SYSTEM
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 408:
A fully digital matrix processor with four inputs and eight 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 cur-
rent 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 408 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.
