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.
