TRANSMITTER AUDIO GAIN ADJUSTMENT
The Guitarist: The audio gain control on the transmitter in The
Guitarist system 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 Headset: The audio gain control on the transmitter in The
Headset system 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.
The Vocal Artist, Presenter and Bodypack: The audio gain con-
trols on the transmitters in The Vocal Artist, Presenter, and Body-
pack systems have been factory preset at the mid-range position.
This will provide the best results in most applications. However, for
singers or presenters with quiet voices, the audio gain may need
to be increased for better signal-to-noise ratio. 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 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.

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.
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.
To Return Audio Gain to the Factory Setting: Rotate the
transmitter audio gain control counterclockwise as far as it
will go (The Guitarist), clockwise as far as it will go (The
Headset), or to mid position (The Vocal Artist, Presenter,
and Bodypack systems).
RECEIVER VOLUME ADJUSTMENT
The volume control on the front panel of the T3 and T4N receiv-
ers 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, ad-

just the receiver volume control until the output reaches the de-
sired level. Rotate the volume control clockwise to increase out-
put. Rotate it counterclockwise to decrease output.
RECEIVER SQUELCH ADJUSTMENT
The squelch control on the T3 and T4N receivers is factory
preset for optimum performance. No further adjustment 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.
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.
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 receiv-
er 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.
