Setup & Operation 7
Section 3: Setup & Operation
3.1 Setup
Before Beginning: Place the rack on a at, sturdy surface. Remove the front and rear cover pieces by
releasing all latches; set the covers aside. Refer to the steps below and Figure 12.
1. Announcer's Interface setup is described below. For more information, refer also to the quick guide
(DD3083838) shipped with the device.
a. Connect the 2' (610 mm) XLR cable between the microphone and the MIC 1 INPUT jack.
b. Connect headphones to the 1/4" or 1/8" jack.
c. Connect the provided 12 VAC wallpack transformer to the power input jack, and then plug
the other end into a standard 120 VAC outlet. Use the tab above the power jack as a strain
relief for the power cord.
2. Connect the 15' (4.6 m) XLR cable from MIC 1 & AUX 1 on the announcer’s interface to MIC 1 &
AUX 1 OUT (A) jacks on the front of the rack.
3. Connect one end of the 2' (0.6 m) or 5' (1.5 m) XLR cable to the LTIBLOX Laptop Interface and the
other end to MIC 2. The 3.5 mm plug may be connected to the headphone jack of a laptop or MP3
player.
4. Connect the 25' (7.6 m) XLR cable between the MAIN OUT (B) jack on the front of the rack and the
SYSTEM AUDIO jack on the bottom of the ber box. If there is no ber box, the cable will typically
connect to a wall plate junction box instead.
5. Locate the 3-prong power cord in the rear of the rack and plug into a standard outlet. Ensure the ber
box (if included) also has power.
6. Turn on the power strip.
7. Switch the SIGNAL to ON.
Follow the above steps in reverse order to power down the system. Place all accessories in a secure location to
avoid damage/theft.
Note: Ensure any optional antennas connected into the jacks off to the sides of the wireless receiver(s) are
perpendicular to the rack and angled outward at ~45°., as shown in Figure 3.
Alternately, coaxial cable from the optional high gain antenna kit may be connected into these jacks.
The antennas should be located within 50' (15.2 m) of the rack, using desktop stands or mounted to the
ceiling. Refer to the Shure®Model PA805 Directional Antenna User Guide for more information.

Setup & Operation 9
3.2 Mixer Operation
Basic instructions are described below. For more information about mixer
operation, refer to the Rane MLM82S Operators Manual.
• Ensure all source equipment is turned on and operational (refer to
appropriate pages).
• For each input channel (source) in use, verify the following settings
as shown in Figure 13:
– SIG/OL light is green; if this light is red, decrease the level
– ASSIGN is set to “A+B” or “B”
Note: Inputs set to “A” will only be heard through the announcer’s
console headphones. This may be used to listen to each input without
interrupting the main mix.
• When the input is in MONO mode, the signal goes to both “A” and “B”
outputs. The amber LED illuminates when in MONO mode (Figure 14).
When not in MONO mode, the input signal goes to the “B” output (as
set in the factory).
• Adjust MASTER VOLUME “B” level (Figure 15) to achieve the nal
output. If the OL light is red, decrease the level.
Remember: Bad input = bad output. No adjustment on the mixer can make a
poor source sound better. For best results, be sure to use high-quality audio les
from your MP3 player or laptop, and set the device to near full volume.

Wireless Mic & Bodypack Operation
1. Open the battery cover. Insert new or fully-charged AA batteries prior to each use, and always have
spares on hand.
2. Power on the transmitter device (Figure 17).
3. Hold the transmitter device up close to one receiver in the rack, ensuring the infrared (IR) windows
are aligned.
4. Press sync on the receiver; “good” will display if sync was successful.
5. Repeat steps 1-4 to pair another transmitter device with an additional receiver (if present).
Note: Plug the referee mute switch into the jack on top of the bodypack unit and plug headphones/
lapel mic into the referee mute switch.
Verify Reception: With a transmitter and the receiver both turned on and having matching GROUP and
Channel numbers, the RF meter on the receiver should be indicating signal. Speak into the microphone and
the TX AUDIO meter should indicate signal presence.
Additional Tips:
• Perform a group and channel scan to obtain the best available channel for microphones.
• Check that battery levels are adequate to prevent wireless equipment from powering off during use.
• Program one microphone per receiver; multiple microphones on the same channel will cause
interference and microphones will drop out.
• Always use quality batteries to prevent battery leaks that can corrode and shorten the life of the
equipment.

3.4 Microphone Best Practices
• Keep handheld microphones 4-6 inches (102-152 mm) from the mouth (about the width of a hand).
“P-pops” are loud sounds created by the release of breath when saying letters like “p” or “b”. To
avoid P-pops, keep handheld microphones below the mouth, angled toward the nose at a 45° angle.
Do not point the front of the microphone straight at the mouth.
• Position headset microphones as close to the mouth as comfortable.
• The referee bodypack kit includes both headset and lapel microphones. In general it is recommended
to use the headset mic for best results. If the lapel mic is desired, clip it onto a lapel, as close to the
center of the chest as possible.
• The softer or louder the speaker’s voice, move the microphone closer or further away, respectively.
• Never hit or intentionally blow into a microphone as it could quite easily be damaged.

Maintenance & Troubleshooting 13
Section 4: Maintenance & Troubleshooting
4.1 Maintenance
• Unplug rack (and ber box, if included) from power during periods of non-use.
• Store equipment in a clean dry place free from moisture, debris, and extreme temperatures.
• Keep announcers rack and equipment covered from dust and debris when not in use.
• Clean equipment annually or as needed using electronic equipment duster and a dry cloth.
