SIM3 performs sourceindependent measurement of the frequency, phase response, and
signal-to-noise ratio of components in the electronicor acoustic signal path in near-real-time,
providingyou the ability to understand the acoustic environment, determine optimal loudspeaker
placement, and configureGalileo snapshots.
Configuring Galileo for SIM3
1. Connect the SIM3 Line Switcher port to a Galileo 616 unit SIM3 bus connector.
2. Select [Galileo Unit] > Settings > SIM3.
3. Set the SIM3 Bus Address.This value will be used in configuring branches in the SIM3
software.
4. Select a SIM3 Trimmode:
■Enabled: The SIM3 Trimcontrol on [Galileo Unit] > Output Processing > Channel
Settingspages will be used to adjust gain to the analyzer, allowing you to directly see
the extent of gain changes. In the SIM3 softwareRoom response will show acoustic
relativegain, Processor will show electronic relative gain, and Result will show the
combination of both.
■Disabled: The SIM3 Trimcontrol on [Galileo Unit] > Output Processing > Channel
Settings pages will be disabled.
5. Select the SIM3 Output ProbePoint:
■OutputPost Delay: Includes TruShaping EQ, Parametric EQ, SIM3 Trim, Polarity,and
Delay controls.select this when tuning frequency-based crossover.
■OutputPost Gain: Includes Output Post Delay controls plus Atmospheric Correction,
Array Correction,High/Low Pass, and Gain controls. select this when tuning relative
levels between systems.
TheGalileo network is now connected to SIM3. Please refer to the SIM3 User Guide for further
details regardingthe use of SIM3.
