4 Sound System Components
Amplifier Components
In sound systems, the amplifier is the last component before the drivers. It receives a signal
from the source equipment and amplifies it to power the speakers. The Sportsound 2000HD
sound system utilizes ten (10) power amplifiers with built-in Digital Signal Processor (DSP),
which manages equalization, limiting, compression, and crossover functions.
Note: The DSP program is set at the factory and is not user adjustable.
2.3 Fiber Conversion Box
The fiber conversion box ( Figure 7 ) converts the
analog audio signal from the source equipment
into fiber optic signal that goes out to the control
enclosure. The box is typically permanently wall-
mounted near the source equipment location.
The fiber conversion box includes an analog
backup signal. This provides a redundant safety,
in case the fiber link to the sound cabinet is lost.
To go into analog backup mode, simply turn the
switch to the
ANALOG position.
Refer to Section 4.3 for more information about
the fiber conversion box.
2.4 Source Equipment
The Sportsound 2000HD audio system is compatible with all Daktronics standard control
systems. Refer to the manual provided with the control system for proper operation.
