Equipment Overview

The Sportsound 1500HD audio system consists of the following elements:

• Sound Cabinet

• Control Enclosure

• Fiber Conversion Box

• Audio Control Rack

• Signal Cables

Sound Cabinet

Figure 3 illustrates a Sportsound 1500HD sound

system cabinet. The cabinet is 6'-0" (1829 mm)

high, 8'-0" (2438 mm) wide, and 3'-6" (1067 mm)

deep. It is composed of a steel skeleton sheeted

in custom aluminum paneling with three rear

access doors. The cabinet is powder coat black

with a wrinkle nish.

Grille

Reference Drawing:

Mesh Layout; 1500HD Gen II ............................................................................. DWG-983304

The grille of the cabinet consists of a woven ame 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'-4.75" (1645 mm) high by 7'-9" (2362 mm) wide.

Drivers

Figure 4 illustrates the three different types of drivers (also known as speakers) used in the

sound cabinet:

• 12" (381 mm) low frequency drivers (part # A-2306)

• 8" (203 mm) mid-range drivers (part # A-2305)

• 1.4" (36 mm) high frequency drivers (part # A-2302)

A-2306 A-2305 A-2302

Figure 4: 1500HD Drivers

Note: All products in this system are tested individually for

product safety approval.

Control Enclosure

Figure 5 illustrates the thermostatically controlled and NEMA3R

control enclosure that houses the ampliers. In sound systems,

the amplier is the last component before the drivers. It

receives a signal from the source equipment and amplies

it to power the drivers. The Sportsound 1500HD sound system

utilizes two ampliers 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 ber conversion box that converts

the analog audio signal from the audio control rack into

ber 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 ber conversion box includes an analog backup signal.

This provides a redundant safety, in case the ber 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 ber

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 specications are as follows:

• Minimum 2-core, multimode 50-micron ber optic cable from ber conversion box

to control enclosure. If included with a Daktronics scoreboard or display, the sound

system may share a ber optic cable run, requiring additional cores.

• 1 pair, 22 AWG audio cable from ber 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)

3 Mechanical Installation

A qualied technician must install the Sportsound 1500HD cabinet and control enclosure.

It is the customer’s responsibility to ensure that a qualied structural engineer approves

the mounting structure and any additional hardware needed to secure the cabinet.

The cabinet must be installed no farther than 40 yards (37 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 specied on shop

drawings. Daktronics also assumes no liability for system damage or injury resulting

from incorrect setup or lifting methods performed by non-Daktronics employees.

Cabinet Installation

Mechanical installation consists of lifting and

mounting the Sportsound 1500HD cabinet onto an

existing support structure.

Lift the Cabinet

The Sportsound 1500HD cabinet may be shipped

with two shipping brackets attached to the top as

shown in Figure 7.

Each bracket is attached to the cabinet with

two 1/2" lift eyes. Refer to Figure 8. Remove the

shipping brackets, and reinstall all four 1/2" lift

eyes in the holes prior to installing the cabinet.

Note: The two smaller front lift eyes are meant

only for removing the grille frame and not

for lifting the cabinet. Refer to Grille Mesh

Replacement (p�12).

Whenever possible, use 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 7: Shipping Bracket, Attached

with Lift Eyes

Figure 8: Shipping Bracket Removed,

Lift Eyes Reinstalled

Mechanical Installation

Cables and chains attached to the eyebolts and

directly to a center lifting point, as shown in the

"Acceptable" 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 cabinet 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°. 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 by the eyebolts or eyebolt holes.

If installers remove the eyebolts, use 1/2" bolts to plug the holes.

Mount the Cabinet

Reference Drawings:

Shop Drawing; Sound System; 1500HD ............................................................ DWG-752494

The sound cabinet will be mounted atop a frame that must be certied by a structural

engineer. To mount the cabinet in place, position it 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 DWG-752494 in Appendix A for mounting

requirements.

Aim the Speakers

Tools Required: 9/16” wrench/socket @2

Reference Drawings:

Note: Installation described below requires I-beams with 3/16" to 3/4" thick beam

anges. If an alternate mounting option for control enclosure is preferred, it is

the responsibility of the installer to adequately secure the enclosure to the base

structure.

The Sportsound control enclosure (shown in Figure 5) mounts toward the base of

the display structure. The enclosure typically mounts on the backside of the support

column(s) within 50' (15.2 m) of the sound cabinet. Refer to the drawings listed under

Mount the Cabinet (p�6) for suggested control enclosure mounting locations.

Attach horizontal Unistrut pieces to the top and bottom rear anges of the control

enclosure with provided 5/16" hardware through the existing holes. Raise the enclosure

to the desired height, using side lift eyes or lifting straps if necessary, and then secure
