Introduction 1
Section 1: Introduction
This manual explains the operation of the Sportsound®Rack (SSR) 100. For additional information regarding
the safety, installation, operation, or service of this system, refer to the telephone numbers listed in Section 6.
This manual is not specic to a particular installation. Project-specic information takes precedence over any
other general information found in this manual.
IMPORTANT SAFEGUARDS
• Read and understand all instructions before beginning the installation process.
• Do not drop the 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.
• Always turn off and/or unplug the control equipment when it is not in use. This keeps equipment
protected from power spikes and lightning.
• Never yank the power cord from the outlet. Grasp the plug and pull to disconnect.
• Do not let any power cord touch hot surfaces or hang over the edge of a table that would damage or
cut the cord. Arrange the cord with care so that it will not be tripped over.
• Inspect control equipment for shipping damage such as rattles and dents, and verify that all
equipment is included as itemized on the packing slip. Immediately report any problems to
Daktronics; save all packing materials if exchange is necessary.
• Keep equipment covered when possible to protect from dust and debris.
1.1 Resources
Figure 1 illustrates a Daktronics drawing label. The drawing
number is located in the lower-right corner of a drawing. This
manual refers to drawings by listing the last set of digits and
the letter preceding them. In the example, the drawing would
be referred to as Drawing D-1007804. All references to drawing
numbers, appendices, gures, or other manuals are presented in

4 SSR-100 Components
2.2 Standard Equipment
Audio Mixer
The Rane MLM82S (Figure 4) features four balanced mono Mic/Line Inputs (XLR) with 15 VDC phantom
power and signal/overload indicators. Each of the four Mic/Line Inputs may be assigned to A, A+B or B
Outputs. Other features include:
• Four balanced stereo line inputs (TRS) with 12 dB of line gain
• Two balanced Outputs (XLR)
Announcer’s Interface
The Daktronics Announcer’s Interface (Figure 5) includes one
(1) balanced MIC output, one (1) balanced AUX input, and
headphone jacks; headphone volume control knob; and momentary
or continuous microphone activation buttons. Microphone and
headphones are provided.
Laptop Interface
This portable, durable balanced audio converter allows connection
of a laptop or mp3/music player into pro-level mixers (Figure 6).
Other features include:
• 1/8" (3.5 mm) male input
• Balanced XLR male output
• Adjustable output volume control
• Black powder-coated aluminum chassis
2.3 Optional Equipment
Wireless Microphone System
The Shure®QLX-D® is a professional UHF wireless microphone system.
Dual receivers in the audio rack allow operation of two wireless transmitters
simultaneously (Figure 7). Over 60 compatible channels per frequency
band and up to 17 compatible systems per 6 MHz TV channel are available. Automatic Frequency Selection
technology detects the clearest frequencies in the area. Other features include:
• Lockable settings
• Battery power gauges
• Effective Range: 328' (100 m) under optimal conditions
• Audio Frequency Response: 20Hz to 20kHz, ±2dB
• Total Harmonic Distortion: <0.1%
• RF Sensitivity: -97 dBm at 10-5 BER

SSR-100 Components 5
High Gain Antenna Kit
The Shure®PA805 (Figure 8) is a directional antenna for increased range and
reduced interference. The “gain” of this antenna enables it to receive signals
from a greater distance than at typical “whip” type antenna. The antenna
allows for increased performance of wireless microphones with 6 db of gain.
The directional antennas may be located up to 50' (15.2 m) away from the
announcer’s rack.
Single-Muff Headset
The professional single-muff headset (Figure 9) may be used in place of the
standard announcer’s interface wired microphone and headphones. Other
features include:
• Ambient noise attenuation
• Neodymium magnet system for high reproduction precision
• Soft, circumaural ear pads
• Cardioid condenser microphone

Headset

6 SSR-100 Components
USB Audio Interface
The Radial®Engineering USB-Pro™ (Figure 10) provides an interface from laptop
computers to balanced outputs. Other features include:
• 24-bit, 96 kHz quality audio
• Two balanced XLR outputs (left and right)
• 3.5mm TRS headphone output
• Ground lift and mono-sum switches
2.4 Signal Cables
Cable specications are as follows:
• 5' (1.5 m) XLR cable for auxiliary audio input (part # W-1627)
• 15' (4.6 m) XLR cable between announcer’s interface and rack (part # W-2074)
• 25' (7.6 m) XLR cable from rack to ber box or wall plate (part # W-1560)
Notes:
• Keep unbalanced cable lengths under 6' (1.8 m) to prevent unwanted noise from being picked up.
Use appropriate converters, such as the LTIBLOX Laptop Interface, to convert to balanced cables
(Figure 11) for longer cable runs if necessary.
• Run audio cables away from power cables to prevent noise.
• Audio cables must be kept separate from current loop (scoreboard control) signal cables.
