Daktronics Sportsound 500HD - Manual (Page 10)

4 Sound System Components
2.3 Control Enclosure
A thermostatically controlled and NEMA3R control
enclosure (Figure 7) 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 speakers. The Sportsound 500HD
sound system utilizes 1 or 2 power amplifiers (depending
on the cabinet model) 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.
Refer to Section 3.2 and Section 4.1 for more information
about the control enclosure.
2.4 Fiber Conversion Box
The fiber conversion box (Figure 8) 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.
2.5 Source Equipment
The Sportsound 500HD audio system is compatible with all Daktronics standard control
systems. Refer to the manual provided with the control system for proper operation.
2.6 Signal Cables
Cable specifications are as follows:
 6-core, multimode 50-micron fiber optic cable from fiber conversion box to 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) signal cable from cabinet to control enclosure (part # W-2317)
