GALILEO GALAXY 816-AES3
The GALAXY 816-AES3 model provides 16 matrix outputs on eight AES3 digital outputs. It
can be used to drive the standard GALAXY 408 and 816’s digital inputs or any other device that
accepts 96 kHz AES digital audio signals. For more information on the GALAXY 816-AES3 and
its differences from the standard GALAXY 816, see Appendix A, “Galileo GALAXY 816-AES3.”
COMPASS CONTROL SOFTWARE
The Compass control software provides comprehensive control of the Galileo GALAXY from
an intuitive graphical user interface on a Mac®or Windows®-based computer. Compass soft-
ware lets you control all features on multiple units.
The Overview tab displays a summary of all GALAXY channels with signal flow. Inputs and
outputs can be labeled and conveniently grouped for simultaneous editing. The Input Pro-
cessing and Output Processing tabs provide access to all DSP settings. Equalization parame-
ters can be edited with numeric entry or by dragging frequency bands. Multiple EQ layers can
be viewed as a composite plot of equalization curves.

CHAPTER 2: FEATURES AND FUNCTIONS
GALAXY PROJECTS AND SETTINGS
GALAXY project files are saved by the Compass control software to the host computer.
Project files contain the full configuration of parameters, system settings, and snapshots
stored in the GALAXY. When a GALAXY is connected to the host computer, the Compass
control software reads and displays the configuration currently residing in the GALAXY.
The Compass control software does not have its own memory for system settings and param-
eters; it just reads what it is connected to. When Compass is connected to a GALAXY, it reads
and displays the parameters and settings of a project file and the current active snapshot and
snapshot library 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 GALAXY
replaces the current snapshot and, if selected, the device settings currently loaded in the
GALAXY.
CAUTION: Opening a project file in the Compass control software when the
computer is connected to a GALAXY overwrites all stored snapshots and current
device settings residing in the GALAXY (if Load Device Settings is selected when
opening the project). To merge snapshots from another project file into the current
library of snapshots in a GALAXY, use the Merge Project option from the Project tab
(click the More>> button for this option to appear).
TIP: You can use the Compass control software to capture GALAXY settings. The
settings are saved as project files or as individual settings files on the host
computer and can be later restored back into the GALAXY. Contact Meyer Sound

Front Panel Input Section
■Input Level Meters: Four-segment LED ladders represent the level for each input channel.
The green LED range begins at approximately -80 dB below clipping. The yellow LED
range lights a few dB below clipping. The top red LED indicates clipping. In the Compass
software (Settings > Input and Output), you can set the Voltage Range for all input and
output channels to either +26 dBu (15.5 V rms) or +16 dBu (7.75 V rms), which determines
the clipping levels.
NOTE: The default Input Voltage Range is +26 dBu.
■Input Mute Buttons: Each input channel has a mute button. Toggling an input mute button
in the Compass software also toggles this mute button.

■Signal / Clip LEDs: Output level is indicated by one multi-color LED for each output
channel. The LED turns green to indicate output levels from -85 dB to -5 dB below
clipping. The LED glows brighter as the signal level increases. The LED turns amber to
indicate levels from -5 dB to just below the clipping level. The LED turns red when the
output signal clips. In the Compass software (Settings > Input and Output), you can set
the Voltage Range for all input and output channels to either +26 dBu (15.5 V rms) or
+16 dBu (7.75 V rms), which determines the clipping levels.
NOTE: The default Output Voltage Range is +26 dBu.
■Output Mute Buttons: Each output channel has a mute button. Toggling an output mute
button in the Compass software also toggles this mute button.
