Introduction 1
Section 1: Introduction
This manual explains the installation, maintenance, and troubleshooting of the Sportsound®2000HD
Sound Cabinet. For additional information regarding the safety, installation, operation, or service of
this system, refer to the telephone numbers listed in Section 7.
IMPORTANT SAFEGUARDS:
Please read and understand all instructions before beginning the installation process.
Do not drop control equipment or allow it to get wet.
Do not disassemble control equipment or electronic controls of the system; failure to
follow this safeguard will make the warranty null and void.
Disconnect system power when not in use or when servicing.
Disconnect system power before servicing power supplies to avoid electrical shock.
Power supplies run on high voltage and may cause physical injury if touched while
powered. Several disconnect switches may be required to de-energize the equipment.
Do not modify the cabinet structure or attach any panels or coverings without the
express written consent of Daktronics, Inc.
This manual is not specific to a particular installation. Project-specific information takes
precedence over any other general information found in this manual.

Sound System Components 3
Section 2: Sound System Components
2.1 Equipment Overview
The Sportsound 2000HD audio system consists of the following elements:
Sound Cabinet
Fiber Conversion Box
Source Equipment
Signal Cables
Note: All products in this system are tested individually for product safety approval.
2.2 Sound Cabinet
The Sportsound 2000HD audio
system cabinet (Figure 3) is 6'-0"
(1829 mm) high, 22'-0" (6706 mm)
wide, and 3'-6" (1067 mm) deep.
It is composed of a steel skeleton
sheeted in custom aluminum
paneling with eight rear access
doors. The cabinet is powder coat
black with a wrinkle finish.
Grille
The grille of the cabinet consists of a woven flame resistant acoustical mesh. The mesh can be
printed in a variety of colors to display advertising, sponsors, or logo designs. The printable
area is 5'-4 3/4" (1645 mm) high by 21'-9" (6630 mm) wide.
Drivers
Three different types of drivers are used in the sound cabinet:
12" (305 mm) low frequency drivers: Daktronics part # A-2306: (Figure 4)
8" (203 mm) mid-range drivers: Daktronics part # A-2305 (Figure 5)
1.4" (36 mm) high frequency drivers: Daktronics part # A-2302 (Figure 6)

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.
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)
