Control Enclosure
Figure 5 illustrates the thermostatically controlled and NEMA3R
control enclosure that houses the amplifiers. 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 drivers. The Sportsound 1500HD sound system
utilizes two amplifiers inside the control enclosure, all with built-
in Digital Signal Processor (DSP), which manages equalization,
limiting, compression, and crossover functions.
The DSP program is set at the factory and is not user-
adjustable.
Refer to Mounting the Control Enclosure (p�7) and Power/
Signal Connections (p�8) for more information about the
control enclosure.
Fiber Conversion Box
Figure 6 illustrates the fiber conversion box that converts
the analog audio signal from the audio control rack into
fiber optic signal that goes out to the control enclosure. The
box is typically permanently wall-mounted near the source
equipment location. Adjustable brackets also allow for rack
mounting.
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. The analog
switch may be moved to the top for rack-mounting.
Refer to Fiber Conversion Box Connections (p�10) for more information about the fiber
conversion box.
Audio Control Rack
The Sportsound 1500HD audio system is compatible with all Daktronics standard control
racks. Refer to the manual provided with the control rack for proper operation.
Signal Cables
Cable specifications are as follows:
•
Minimum 2-core, multimode 50-micron fiber optic cable from fiber conversion box
to control enclosure. If included with a Daktronics scoreboard or display, the sound
system may share a fiber optic cable run, requiring additional cores.
•
1 pair, 22 AWG audio cable from fiber conversion box to control enclosure for analog
backup (part # W-1615)
•
60' (18.3 m) speaker cable (located inside audio cabinet) that routes to the control
enclosure (part # W-5103349)
