FIGURE 8. WIRELESS SYSTEM OPERATION
ESTABLISHING A WIRELESS LINK
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.
T o 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 (
(
AXR4N
) should illuminate.
AXR3
) or one of the ANTENNA lights
• If the RF or ANTENNA lights do not illuminate, see the
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 location. If external RF sources cannot be avoided, you may
need a wireless system that operates on a di fferent carrier
frequency. Contact your Shure dealer.
OPERATING YOUR WIRELESS SYSTEM
1. Once you have established a wireless link, slide the transmitter MUTE switch to the ON position.
2. Sing, speak, or play your instrument at typical volume levels. (AXSGW systems: turn the volume control on your guitar 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 re d PEAK light (AXR3) or TRANSMITTER
AUDIO PEAK light (AXR4N) when loud sounds are transmitted
.
NOTE: If the red TRANSMITTER AUDIO PEAK light on the
receiver does not flicker occasionally, refer to the
System Adjustments
Section below.
3. When finished, slide the MUTE switch to MUTE. Then slide
the transmitter POWER switch to OFF. (Muting the transmitter first will help prevent audio thumps that may occur when
powering off the transmitter.)

TRANSMITTER AUDIO GAIN 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
controls are turned all the way up, increase the transmitter gain
level. This will ensure the best signal-to-noise ratio for performance. See Figure 9.
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 reduce 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 Figure 9.
AXS31/AXS58/AXSL WD: The audio gain controls on the transmitters in these systems have been fac tory preset at the midrange position. Thi s will p rovide the best results in most applications. However, for singers or presenters with quiet voices, the
audio gain may n eed to be increased for better signal-to-noise ratio. Increase t he gain unt il t he r eceiver’ s TRANSM ITTER A UDI O
PEAK light f licker s when you s peak i n a l oud v oice. For those with
loud voices, the preset gain level may be too high, causing unwanted distortion. In this case, the PEAK indicator will glow continuously when you sing or speak in a loud voice and the gain
level should be reduced. See Figure 9.

RECEIVER VO LUME ADJUSTMENT
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 microphone. After making any necessary transmitter gain adjustments, adjust the receiver volume control until the output reaches the desired level. Rotate the volume control clockwise to
increase
output. Rotate it counterclockwise to
decrease
output.
RECEIVER SQUELCH ADJUSTMENT
The squelch control on the AXR3 and AXR4N receivers is
factory preset for optimum performance. No further adjust-
ment is nor m ally 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 muting), but
•
Turning the squelch control counterclockwise allows a lower quality signal through (more noise before muting), but

To return the receiver squelch control to the factory setting, rotate it to the mid-range position (so the slot is vertical).

TIPS FOR ACHIEVING MAXIMUM PERFORMANCE
•
Make sure you can always see a receiver antenna from the
transmitter position.
•
Keep the distance between the transmitter and the receiver antennas short.
•
Avoid placing the receiver antennas near metal surfaces
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.
