Chapter 6 Operation
This section provides details about DSAi operation. The general
operation of a DSAi module 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. 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 module 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 DSAi
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 DSAi module 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.
2. Input Clip: If this indication is enabled, random flashing shows that
the audio input signal is clipping the A to D converters at the input.
To correct this condition, reduce the input signal level at the source.
Because the input gain is after the A to D converters, the DSAi input
gain adjustment will have no effect on this condition.
