Daktronics Sportsound 1500HD - Manual (Page 10)

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 1500HD
sound system utilizes four (4) 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 1500HD audio system is compatible with all Daktronics standard control
systems. Refer to the manual provided with the control system for proper operation.
2.5 Signal Cables
Cable specifications are as follows:
 6-core, multimode 50-micron fiber optic cable from fiber conversion box to fiber
splice box or control enclosure (part # W-1489)
If included with a Daktronics scoreboard or display, the sound system may share
fiber optic cable (12-core part # W-1490).
 1 pair, 22 AWG audio cable from fiber conversion box to control enclosure for analog
backup (part # W-1615)
 50' (15.2 m) fiber patch cable from fiber splice box to control enclosure (part # W-1512)
