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” adjustments using external equalization

These operation instructions assume that the loudspeaker has AC Mains, audio signal, and computer control lines properly connected, and that they are passing signals correctly.

There are several, unique functions that affect and enhance operation. These include Power Management, LED Indicator, and signal Monitoring.

The Power Management feature is a power saving function that improves energy efficiency. This feature automatically puts the DSA amplifiers into stand-by mode similar to a computer monitor. The initiation of this mode occurs after the input signal is absent for a period of time.

Enable or disable this function using DSAPilot. If enabled, the period of time the input signal must be absent before entering stand-by is adjustable. In addition, DSAPilot allows forcing the standby condition should the need arise to de-activate the amplifiers without disconnecting the AC mains.

The LED Indicator located on the front of a DSA loudspeaker at the “Signal End” can be set to indicate the status of several operating conditions. Enable or disable each indication using DSAPilot. The actual conditions monitored by the LED are not affected by enabling or disabling the LED indication.

1.Initialization: The LED on the “Signal End” will flash rapidly for about 3 seconds when first powered on. This is normal and indicates the electronics are being initialized. The LED should then go off. This indication is permanently enabled.
