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.

Figure 6: A-2302

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)
Figure 7: Fiber Conversion Box

Mechanical Installation 5
Section 3: Mechanical Installation
A qualified technician must install the Sportsound 2000HD sound system cabinet. It is the customer’s
responsibility to ensure that a qualified structural engineer approves the mounting structure and any
additional hardware needed to secure the cabinet.
The cabinet must be installed no further than 100' (31 m) behind the goal post to provide coverage for
seating from goal to goal.
Note: Daktronics assumes no responsibility for the structure’s integrity. The engineer responsible
for the attached-to base structure shall evaluate the adequacy of their structure to support the
gravity loads imparted by the cabinet at each attachment point in combination with other
associated loading conditions. Daktronics assumes no responsibility for system damage or injury
resulting from installation methods that deviate from attachment details specified on shop
drawings. Daktronics also assumes no liability for system damage or injury resulting from
incorrect setup, or incorrect lifting methods preformed by non-Daktronics employees.
3.1 Cabinet Installation
Reference Drawings:
Shop Drawing; Sound System; 2000HD................................................Drawing C-330901
The Sportsound 2000HD sound system installation consists of lifting and mounting the
cabinet onto an existing support structure. Refer to Drawing C-330901 in Appendix A for
further mounting detail.
Lifting the Cabinet
The Sportsound 2000HD speaker cabinet is shipped
with four (4) 5/8" lift eyes (Figure 8) for lifting the
cabinet into place.
Note: Three (3) shipping brackets are installed to
the top of the cabinet for shipping purposes only.
Each bracket is attached to the cabinet with two (2)
1/2" hardware sets. Remove all shipping brackets
prior to lifting and installing the cabinet.
Daktronics strongly recommends using a spreader bar, or lifting bar, to lift the cabinet.
Spreader bars ensure the force on the eyebolts remains straight up, minimizing lifting stress.
Figure 9 illustrates the preferred lifting method on the left and an acceptable alternative
lifting method on the right. When lifting the cabinet:
Use a spreader bar if possible.
Use every lifting point provided.
Figure 8: Shipping Bracket & Lift Eyes

6 Mechanical Installation
Cables and chains attached to the eyebolts and directly to a center lifting point, as shown in
the right-hand example in Figure 9, can create a dangerous lateral force on the eyebolts and
may cause the eyebolts to fail. The smaller the angle between the cable and the top of the
cabinet, the lighter the sign must be to safely lift it. If this method must be used, ensure a
minimum angle between the chain and cabinet of at least 45°.
Do NOT attempt to lift the cabinet if the angle is less than
45 degrees. Exceeding load angles or weight limits could
cause the bolts in the cabinet to buckle, resulting in
serious damage to the equipment or injury to personnel.
Also, loads should be applied directly in the plane of the
eyebolt as shown in Figure 10.
Note: Daktronics assumes no liability for damages
resulting from incorrect setup or lifting methods.
Eyebolts are intended for lifting only. Do not attempt
to permanently support the cabinet with the eyebolts
or eyebolt holes.
If installers remove the eyebolts, use 5/8" bolts to plug
the holes.
Mounting the Cabinet
The sound cabinet will be mounted atop a frame that must be certified by a structural
engineer. To mount the system in place, position the cabinet on the structure where it is to be
mounted. Weld the cabinet’s bottom members to the structure at the locations indicated on
the shop drawing. Refer to Drawing C-330901 in Appendix A for mounting requirements.
Aiming the Speakers
Once the cabinet has been mounted in place, it may be necessary to adjust the direction of the
speakers based on the specific facility. Drawing C-1023805 in Appendix A provides speaker
aiming instructions as well as recommended angles to position the speakers, based on the
cabinet’s location in relation to the seating area(s).

Electrical Installation 7
Section 4: Electrical Installation
CAUTION –RISK OF ELECTRIC SHOCK: Only qualified individuals should perform power routing
and termination to the system. It is the responsibility of the electrical contractors to ensure that all
electrical work meets or exceeds local and national codes. Failure to follow installation guidelines will
result in audible noise on the sound system and possible damage to internal components.
Notes:
This product is not provided with mains disconnect. Customer shall provide disconnect at
base of sound system location that meets or exceeds local and national electrical codes.
Several disconnect switches may be required to de-energize the equipment before servicing.
The control enclosure, located in the sound cabinet, shall not be exposed to dripping or
splashing, and no objects filled with liquid shall be placed on the control enclosure.

access door (Figure 11). Turn all latches a 1/4 turn using a flathead screwdriver (older latches
can be turned with fingers). Tilt the top of the door away from the cabinet. With the door
tilted, use the handle to lift it up and out of the doorframe.
Figure 11:Sound Cabinet Access Doors, Rear View

8 Electrical Installation
To access the internal components of the control enclosure, first loosen the 6 screws with a
Philips head screwdriver, and then use the handle to lift the enclosure cover up and away so
the screws pass through the keyholes.
Refer to Figure 12 for component and connection locations within the sound cabinet and
control enclosure and Drawing B-1082599 in Appendix A for a detailed wiring schematic.
Power
The system requires three (3) 20 amp 208/230/240 circuits (50 or 60 Hz); 2W + GND per
circuit. Power wiring must be run in conduit up into the bottom of the sound cabinet and
terminated at TBL2. Refer to Detail “F” of Drawing C-984140.
Figure 12:Control Enclosure Components & Connections (Covers Removed)

Electrical Installation 9
Signal
Six-core, multimode 50-micron fiber optic cable (Daktronics part # W-1489) must be run in
conduit from the fiber conversion box location and terminated in a fiber splice box near the
sound cabinet. Fiber patch cables (part # W-1512) will then run in conduit to the control
enclosure media converter (FCC2). Refer to Detail “C”and Detail “E” of Drawing C-984140.
If there is no fiber splice box, the fiber is terminated directly to the media converter.
Note: The sound system may instead use 12-core (part # W-1490) fiber optic cable.
For the analog backup signal, 1 pair, 22 AWG cable (part # W-1615) must be run in conduit
from the fiber conversion box location to the sound cabinet control enclosure (TRX1). Refer to
Detail “E”of Drawing C-984140. The analog backup cable may pass through, but not
terminate in, a fiber splice box.
Grounding
The sound cabinet must be grounded according to the provisions outlined in Article 250 and
600 of the National Electrical Code and according to the specifications in this manual or the
warranty will be void. Proper grounding is necessary for reliable equipment operation and
protects the equipment from damaging destructive disturbances and lightning.
Daktronics recommends a resistance-to-ground of 10 ohms or less. The electrical contractor
performing the electrical installation can verify ground resistance. Daktronics Sales and
Service personnel can also provide this service. The sound system must be earth-ground.
The material for an earth-ground electrode differs from region to region and may vary
according to conditions present at the site. Consult local and national electrical codes.
Daktronics does not recommend using the support structure as an earth-ground electrode;
concrete, primer, corrosion, and other factors make the support structure a poor ground.
Note: The support structure may be used as an earth-ground electrode only if designed to
do so. A qualified inspector must approve the support structure and grounding methods.
4.2 Lightning Protection
The use of a disconnect near the system to completely cut all current-carrying lines
significantly protects the circuits against lightning damage. In order for this device to provide
protection, the power must be disconnected when the system is not in use.
4.3 Fiber Conversion Box Connections
Important Notes:
The fiber box shall not be exposed to dripping or splashing, and no objects filled with
liquid shall be placed on the fiber box.
The fiber box consists of Class 1 construction and shall be connected to a mains
socket outlet with a protective earth-ground connection.
The fiber box utilizes a power cord with wiring inlet as a means for disconnection
from power. This means of disconnection shall remain readily operable in all cases.

Maintenance & Troubleshooting 11
Section 5: Maintenance & Troubleshooting
5.1 Maintenance
Grille Maintenance and Cleaning
To allow maximum acoustic transparency, the front of the cabinet contains a PVC mesh
grille. Do not apply anything to the surface that may obstruct the holes in the material.
To maintain the brightness of the colors and prolong the life of the grille, periodic cleaning is
necessary. Failure to clean periodically may result in permanent discoloration or staining.
When cleaning, use a mild soapy solution (Dove®, Ivory®, etc.) and a very soft brush, moving
in a circular motion. Rinse with clean water using normal faucet pressure.
Note: Do not use a power washer.
Replacing the Grille Mesh
If the speaker mesh fades or tears over time, or if new graphics/logos are desired, it may be
replaced. Only qualified sign companies should be used to replace the speaker mesh. Refer to
Drawing B-983337 for speaker mesh layout. Contact Daktronics for mesh reordering.
1. Removing Mesh Frame
The front of the sound cabinet has a removable aluminum frame that secures the
speaker mesh. This frame is attached to the sound cabinet with a total of twenty (20)
3/8" hardware sets, with ten (10) sets at both the top and bottom of the frame.
a. Carefully remove all mounting hardware and safely lower mesh frame to the
ground. Set the frame on a level surface large enough so that the weight is
supported by the aluminum frame and not on the mesh.
b. Loosen the set screws using a square driver on radius cover and remove.
2. Removing Tension Clips
Insert the tip of a standard
slotted screwdriver into the
recess located at the backside
of the tension clip (Figure 15).
Rotate or tilt the screwdriver to
separate the tension clip teeth
away from the frame. This will
allow the tension clip to be
removed from the frame by
prying or pulling it up and out.
Slide the mandrel out of the
tension clip to release the mesh.
Figure 15:Removing Tension Clips

12 Maintenance & Troubleshooting
3. Attaching New Speaker Mesh
When ordered through Daktronics, the mesh has a line with a series of tick marks
printed on the front (Figure 16). These tick marks are used to indicate the location of
the tension clips and mandrels.
a. Place a mandrel, smooth side up, centered on the tick mark.
b. Fold the mesh around the mandrel. Ensure the groove in the mandrel is
towards the inside of the mesh (Figure 17).
c. Snap a tension clip over the mandrel and mesh (Figure 18). Do not try to
drive both ends of the clip down onto the mandrel and fabric at the same
time; snap one end down and then the other.
d. Continue to place a mandrel and tension clip on every tick mark.
Figure 16:Tick Marks on Mesh
Figure 17:Folding Mesh
Figure 18:Attach Tension Clip

Maintenance & Troubleshooting 13
e. Lay the mesh across the frame and snap each clip into the tension channels
(Figure 19).
f. Use the tensioning tool provided with the mesh replacement kit (part # 0A-
1340-2032) to drive the tension clips into the tension channels (Figure 20).
Start with one or two clicks.
g. Work around the frame, tightening down all the tension clips until all the
wrinkles are removed and the mesh is properly taut.
Note: Do not over-tension! This may cause damage to mesh graphics. Apply
just enough tension to achieve a smooth, flat surface.
h. Place the radius covers on the end of the mesh frame and tighten the set
screws on the radius cover.
4. Reattach Mesh Frame
Safely lift mesh frame back in place on the front of the sound cabinet and attach with
the twenty (20) 3/8" hardware sets. Ensure the frame is snug tight against the cabinet.
Figure 19:Clips in Channels
Figure 20:How to Use Tensioning Tool
Note: Pull on the corners of the mesh
to remove any wrinkles. When
pulling on the fabric, do not pull
directly on the fabric flap or tension
clip, or the clip may pop off. When
pulling on the face, grasp the fold
and pull the face into place.
