    Chapter 6 Operation The general operation of a DSA loudspeaker is similar to the operation of most loudspeakers. Initial system set-up and overall tuning adjustments detailed in this Chapter must be made using DSAPilot. For details about using DSAPilot functions refer to the DSAPilot Help File. Performance operation is largely concerned with adjusting the operating levels, avoiding excessive input signals and, if needed, making in-performance “voicing”...

    NOTE: A battery is used to retain the DSA’s settings when disconnected from the AC Mains. A low battery requires replacement by the EAW Service Department or the service department of the EAW Distributor for your country. Expected battery life is 10 years without being connected to the AC mains.
