FIGURE 8. WIRELESS SYSTEM OPERATION  
ESTABLISHING A WIRELESS LINK  
OPERATING YOUR WIRELESS SYSTEM  
When powered on, your transmitter broadcasts an RF carrier  
signal. When picked up by your receiver, this signal links your  
wireless system together and allows wireless transfer of audio  
signals from your microphone or instrument. The RF signal is  
broadcast steadily, even when your transmitter is muted. The  
yellow RF light (AXR3) and ANTENNA A/B lights (AXR4N) indi-  
cate when this link is established.  
To test your wireless link, setup your transmitter and receiver as  
described above. Turn on your transmitter while remaining  
close enough to the receiver to see the yellow RF or ANTENNA  
lights. The RF light (AXR3) or one of the ANTENNA lights  
1. Once you have established a wireless link, slide the trans-  
mitter MUTE switch to the ON position.  
2. Sing, speak, or play your instrument at typical volume lev-  
els. (AXSGW systems: turn the volume control on your gui-  
tar or bass all the way up.) Normal operation is indicated by:  
Steady glow of yellow RF light (AXR3) or ANTENNA light A  
or B (AXR4N).  
Flickering of the red PEAK light (AXR3) or TRANSMITTER  
AUDIO PEAK light (AXR4N) when loud sounds are trans-  
mitted.  
(AXRIf4tNh)esRhoFuoldr iAlluNmTiEnNatNe.A lights do not illuminate, see the  
NOTE: If the red TRANSMITTER AUDIO PEAK light on the  
receiver does not flicker occasionally, refer to the Wireless  
System Adjustments Section below.  
Troubleshooting section in this guide.  
Turn your transmitter off. The RF or ANTENNA light should go  
out. If the RF or ANTENNA lights do not go out after you turn off  
your transmitter, your receiver is picking up an RF signal  
from some other source. If you cannot identify and remove  
this source (usually other digital or wireless electronic  
equipment nearby), place your receiver in another loca-  
tion. If external RF sources cannot be avoided, you may  
need a wireless system that operates on a different carrier  
frequency. Contact your Shure dealer.  
3. When finished, slide the MUTE switch to MUTE. Then slide  
the transmitter POWER switch to OFF. (Muting the transmit-  
ter first will help prevent audio thumps that may occur when  
powering off the transmitter.)

WIRELESS SYSTEM ADJUSTMENTS  
TRANSMITTER AUDIO GAIN ADJUSTMENT  
RECEIVER VOLUME ADJUSTMENT  
AXSGW Systems: The audio gain control on the transmitter in  
these systems is factory-preset at the minimum setting (full  
counterclockwise) to reduce the risk of overload and distortion.  
If the red TRANSMITTER AUDIO PEAK light on the receiver  
does not flicker when the guitar is played loudly and its volume  
controls are turned all the way up, increase the transmitter gain  
level. This will ensure the best signal-to-noise ratio for perfor-  
mance. See Figure 9.  
The volume control on the front panel of the AXR3 and AXR4N  
receivers can be adjusted to make the wireless system output  
level identical to that of a cabled guitar or bass or wired micro-  
phone. After making any necessary transmitter gain adjust-  
ments, adjust the receiver volume control until the output reach-  
es the desired level. Rotate the volume control clockwise to  
increase output. Rotate it counterclockwise to decrease output.  
AXSHW Systems: The audio gain control on the transmitter in  
the headset systems is factory preset at the maximum setting  
(full clockwise). This is because the microphone in the WH20 is  
a low output, dynamic microphone. It may be necessary to re-  
duce the transmitter gain until the red TRANSMITTER AUDIO  
PEAK light flickers only when you speak or sing loudly. This will  
ensure the best signal to noise ratio for performance. See Fig-  
ure 9.  
RECEIVER SQUELCH ADJUSTMENT  
The squelch control on the AXR3 and AXR4N receivers is  
factory preset for optimum performance. No further adjust-  
ment is normally required. It is possible to adjust the squelch  
control setting to emphasize either signal quality or system  
range:  
Turning the squelch control clockwise causes the receiver  
to demand a higher quality signal (less noise before mut-  
ing), but decreases operating range.  
AXS31/AXS58/AXSLWD: The audio gain controls on the trans-  
mitters in these systems have been factory preset at the mid-  
range position. This will provide the best results in most applica-  
tions. However, for singers or presenters with quiet voices, the  
audio gain may need to be increased for better signal-to-noise ra-  
tio. Increase the gain until the receiver’s TRANSMITTER AUDIO  
PEAK light flickers when you speak in a loud voice. For those with  
loud voices, the preset gain level may be too high, causing un-  
wanted distortion. In this case, the PEAK indicator will glow con-  
tinuously when you sing or speak in a loud voice and the gain  
level should be reduced. See Figure 9.  
Turning the squelch control counterclockwise allows a low-  
er quality signal through (more noise before muting), but in-  
creases operating range.  
To return the receiver squelch control to the factory setting, ro-  
tate it to the mid-range position (so the slot is vertical).  
ABOUT THE SHURE NOISE SQUELCH SYSTEM  
Conventional squelch circuits analyze RF signal strength. Conse-  
quently, they cannot discriminate between noise and desired sig-  
nals. When a wireless system is used in a noisy RF environment,  
conventional circuits may “open” unexpectedly, sending loud  
bursts of noise through the receiver when the transmitter’s signal is  
weak or turned off. Unlike conventional wireless systems, Shure  
T-Series systems use a noise squelch circuit that analyzes signal  
quality instead of signal strength. A special detector monitors the  
level of high frequency noise. When the transmitter signal is  
strong, the system’s noise level is low and the receiver sends au-  
dio through. When the transmitter signal is weak or absent, the  
system’s noise level is high and the squelch circuit will mute the  
receiver. This virtually eliminates the possibility of annoying bursts  
of noise coming through your receiver.

FIGURE 9. GAIN ADJUSTMENT  
To Increase Gain: Rotate the transmitter gain control clock-  
wise with the supplied screwdriver until the red TRANS-  
MITTER AUDIO PEAK light on the receiver flickers when  
the guitar is played loudly, or when you sing or speak in a  
loud voice.  
TIPS FOR ACHIEVING MAXIMUM PERFORMANCE  
Make sure you can always see a receiver antenna from the  
transmitter position.  
To Reduce Gain: Rotate the transmitter gain control counter-  
clockwise until the red TRANSMITTER AUDIO PEAK light  
on the receiver flickers only when the guitar is played  
loudly, or when you speak or sing in a loud voice.  
Keep the distance between the transmitter and the receiv-  
er antennas short.  
Avoid placing the receiver antennas near metal surfaces  
To Return Audio Gain to the Factory Setting: Rotate the  
transmitter audio gain control counterclockwise as far as it  
will go (AXSGW systems), clockwise as far as it will go  
(AXSHW systems), or to mid position (AXS31, AXS58 and  
AXSLWD Systems).  
and obstructions. They will reduce system performance.  
To mount the receiver on a flat surface, attach the four  
adhesive rubber feet or secure the receiver to the surface  
with the supplied cloth fastening strips.
