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.

6.1 Operational Functions

There are several, unique functions that affect and enhance operation.

These include Power Management, LED Indicator, and signal Monitoring.

6.1.1 POWER MANAGEMENT

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.

6.1.2 LED INDICATOR

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.
