18. ARC FUNCTION SETTING
18.1. What is the Automatic Resonance Control (ARC) Function?
ARC stands for Automatic Resonance Control.
It is a function that automatically creates a sound field compensation filter (ARC filter) to improve sound clarity
by automatically measuring the inherent acoustic characteristics in architectural space.
18.2. Notes on ARC Function Setting
• Before operating the ARC function, check that sound is actually output from the speakers after installation
and connection completion.
• The ARC filter is set to the output channels to which this filter was assigned at the time of ARC measurement.
• When the ARC filter has already been set, it is overwritten by the newly set filter after completion of ARC
measurement.
• To reset the ARC filter, disable the ARC function. (See p. 35.) In this case, all the ARC filters assigned to
the output channels are initialized. Individual filters cannot be reset.
