The Galileo Callisto 616 AES primary array
processor is an elegant hardware and
software solution for driving and aligning
Meyer Sound loudspeaker array systems.
The 2-space, rack-mount Callisto 616 AES
includes six inputs, 16 digital outputs with
8 mirrored analog outputs, and a fully
digital matrix processor. The accompanying
Compass
®
control software provides
comprehensive control of all parameters
from a Mac
®
or Windows
®
-based computer.
Designed as an effective mastering tool
driving digital audio to satellite Galileo
616, 408 and Callisto 616 processors, the
Callisto 616 AES features delay integration
for aligning loudspeaker arrays, atmospheric

correction filters, and simultaneous low-
and high-pass filters for subwoofer control.
The Callisto 616 AES offers an extensive
equalization architecture that includes
U-Shaping
®
equalization, comprised of
five bands with adjustable slopes, widths,
and gain, and 5-band complementary
phase parametric filtering, both available
on outputs. Additional 5-Band parametric
filters and TruShaping
®
equalization,
comprised of four bands equalization with
adjustable widths and gain, is available on
inputs.
Equalization parameters are easily edited
in the Compass control software, with

Features & Benefits
Simultaneous low- and high-pass filters
Up to 2 seconds of delay on inputs and
outputs
Front-panel LED ladder meters on inputs,
presence/clip LEDs on outputs, and
illuminated mute switches

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 Callisto 616 AES 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
