High Gain Antenna Kit

The Shure®PA805 (Figure 7) 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 8) 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

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

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 to convert to balanced cables (Figure 10) 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.

3 Setup and Operation

Setup

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 11.

1� Announcer’s Interface setup is described below. 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 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 the MIC 1 & AUX 1 (OUT 2) jacks on the front of the rack. Also, plug the wallpack

transformer into one of the power outlets on the front of the rack.

3� Connect the 1/8" to 1/8" cable (part # W-3511512) between the MUSIC input on the

Multimedia Mixer and the headphone jack of a laptop or MP3 player.

4� Connect the 25' (7.6 m) XLR cable between the MAIN OUTPUT (OUT 1) 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, as in an indoor system, the cable typically connects to a wall plate

junction box.

5� Plug the 3-prong power cord in the rear of the rack into a standard outlet. Ensure the

ber box (if included) also has power.

6� Turn on the power strip, mixer, and optional wireless receiver(s).

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.

Mixer Operation

1� Ensure all source equipment is turned on and operational. If

any optional wireless microphone systems are included, refer

Wireless Mic System Operation (p�11).

2� For each channel (input source) in use, verify the green LED is

illuminated, and then turn up the knob until the red LED starts

to light, and then turn it down by one half to one full number

(Figure 12).

Note: For each MIC input, depress the LOW CUT button as

needed to help increase speech intelligibility.

3� Adjust the OUT volume level(s) to achieve the nal output

(Figure 13). If the red LED(s) illuminate, decrease the level(s).

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.

Whenever red LEDs are illuminated on the mixer, this is generally

a sign that input settings need adjustment.

PROLONGED OVERLOAD OUTPUT SIGNAL WILL DAMAGE THE AUDIO SYSTEM!

DIP Switch Settings

1� DUCKER ON/OFF

ON (default) = When audio is sensed above a

threshold at MIC 1 and/or MIC 2 inputs, all other

inputs will be reduced to the level set by the

ducking level (switch 2). All other inputs will

gradually come back up to normal output level

automatically. Note that the CV Input will mute all

other inputs of mixer when signal is sensed above a

threshold regardless of this switch setting.

OFF = Signal levels will not be automatically

reduced. Exception: the CV Input will mute all inputs.

2� DUCKING LEVEL

-15 (default) = When ducker is active, MIC 3 & 4, MIC/LINE 1 & 2, RCA 1 & 2, and

MUSIC inputs will be reduced by 15dB.

-70 = When ducker is active, MIC 3 & 4, MIC/LINE 1 & 2, RCA 1 & 2, and MUSIC inputs

will be muted

3� LIMIT 1 ON/OFF

ON (default) = OUT 1 level will be limited to threshold (switch 4).

OFF = OUT 1 level is not limited – improper use of mixer with limiter off may damage

sound system!

4� LIMIT 1 THRESHOLD

+4 (default) = Allows OUT 1 to reach full line level output while protecting against

improper use and large signal spikes.

-6 = Reduces OUT 1 output level while providing the greatest protection against

improper use of the sound system.

5� LIMIT 2 ON/OFF

ON (default) = OUT 2 level will be limited to threshold (switch 6).

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 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.

Setup and Operation

13

Microphone Best Practices

• Keep handheld microphones 4–6" (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 softer or louder the speaker’s voice, move the microphone closer or farther

away, respectively.

• Never hit or intentionally blow into a microphone as it could quite easily be

damaged.

• The referee bodypack kit includes both head-worn 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.

• Head-worn: Best choice for feedback rejection; capable of more gain before

feedback since microphone can be positioned close to the mouth. Placement

on head should be taken into consideration; mic boom should be on same side

of point source sound system for proper cancellation. More susceptible to wind

noise than omnidirectional microphones.

• Omnidirectional Lapel: Susceptible to feedback from sound system; least

affected by wind noise

• Cardioid Lapel: Better feedback rejection versus omnidirectional lapel, but more

wind noise. For maximum wind noise reduction, use both the snap-on windscreen

AND the furry windjammer on the lapel mic as shown in Figure 18.

Figure 18: Proper Ref Mic Setup

Setup and Operation

14

Feedback

Feedback is a high-pitched noise caused when the sound through a speaker is picked

up again by the microphone. If there is feedback in the system, it can be removed/

reduced with the tips below:

• Practice proper microphone placement. The mic should be as close as possible

to the mouth. Use a headset whenever possible; lapel mics are more prone to

feedback.

• Practice proper setup of the gain structure throughout the system. Start from the

source (wireless mic system) and ensure all levels are good.

• Make sure to use the windscreens on the microphones.

• Try a different mic. Cardioid mics will have a higher gain before feedback than

omnidirectional mics. However, Cardioid mics will have more wind noise versus

omnidirectional. When it comes to choosing between wind noise or feedback, it’s the

lesser of two evils to listen to wind noise.

• Be aware of areas prone to feedback, such as from the 20 yard line and in.

Communicate to the referee that they shouldn’t be making announced calls past a

certain point on the eld.

For additional recommendations for reducing wireless microphone dropouts and

feedback, refer to the Wireless Mic Best Practices (DD3871886), available online at

www.daktronics.com/manuals.
