My pg14 transmitter died mid rehearsal. battery strength is strong. ready light on receiver is on. however, when i play there is no audio transmitted and my transmitter channel display dies(inside the transmitter). i've changed batteries/channels, but after about fifteen seconds, the transmitter channel display dies. any ideas?

I would contact Shure for advice.

A transmitter works by turning the audio/video device it is connected to into a audio and video signal broadcaster. So that when a receiver is connected to another device within range of the transmitter it will be able to pick up the signal from the transmitter and play on this second device. Say you have a TV in the family room and one in your bedroom, if you connect a transmitter to the one in the family room and a receiver to the one in the bedroom they will both be able to receive the same transmission.

1. Check microphone(s) batteries and replace if the
charge is low.
2 Remove local sources of UHF interference, such as
lighting equipment.
3. Adjust the squelch controls on the front of the UHF-
5800 receiver.
4. Signal may be too weak. If so, reposition antennas.
If possible, move them closer to the transmitter.
5. Reposition the receiver, perform a "walkthrough",
and observe the signal strengths. If audio dropouts
persist, mark these "dead spots" in the operating
area and avoid them during the performance.
If none of these could help it is possible that the device has really some faulty operation and needed to carry it to service center.
Good luck!

Hello
Although it has 2 antennae the AT201 is a single channel transmitter and receiver. As you move the transmitter about in relation to the receiver you are finding 'dead spots' in the room where the signal is reduced or even drops out completely. You can reduce the impact of this somewhat by doing the following things.

1. Make sure there is a clear line of sight between transmitter and receiver.
2. Move transmitter and receiver closer together
3. Do not locate the receiver near large pieces of metal or near other electrical equipment, particularly things that have strong magnetic fields like transformers (including amplifier power-supplies) CD or DVD players, hearing loop amplifiers and loop cables.
4. Turn off mobile phones and any other radio operated equipment that is not needed
5. Turn the trim control on the transmitter to the maximum output that you can without causing distortion. The stronger the original signal from the transmitter the lower the related noise will appear to be (called signal - noise ratio)
6. Turn the squelch control on the receiver up a bit to suppress noise - however doing so will reduce the strength of the output signal a bit so don't over do it.
7. Use good quality screened cable between the receiver and your amplifier. Unfortunately the AT201 only has an un-balanced mono jack socket so this cable will be more prone to pick up radio interference than a twin core plus screen (balanced) cable.
8. Make sure that your signal cable does not run parallel to, and close to, any mains electricity cables. If the signal cable needs to cross any mains cables it should do so at 90 degrees and the cables router well away from each other.

However the only real solution to this sort of problem is to use a full duplex (2 channel) transmitter / receiver system which will automatically switch to whichever channel is carrying the stronger signal. Typically these cost about 70% more than single channel units but they often use balanced cable outputs (stereo jack or xlr) which further reduce the propensity for noise due to interference.

hello there, Many steps to do

1. For your AirLine system to work correctly, both the receiver and transmitter must be set to the same channel. and check to make sure that the supplied receiver and transmitter are set to the same channel.

2. Physically place the receiver where it will be used (the general rule of thumb is to maintain "line of sight" between the receiver and transmitter
so that the person using or wearing the transmitter can see the receiver). The CR77 can be rack-mounted if desired (taking a half-rack
space), using an optional Samson adapter kit. The UM1 can be mounted to a video camera using the supplied velcro.

3. Extend the receiver antenna(s) and place it (them) in a vertical position. Make sure the Power on-off switch in your AH1 transmitter is set
to "Off."

4. Gently pry off the battery cover off the AH1 transmitter and slide it upwards and off to open the battery compartment. Please use care
when opening this cover as undue force will destroy the hinge.

5. Place a fresh AAA alkaline battery in the transmitter battery compartment, taking care to observe the polarity markings. Then replace the
battery cover and gently press down on it until it clicks. Leave the AH1 off for the moment.

6. Make the physical cable connection between the receiver output jack and a mic level audio input of your amplifier or mixer. The balanced
XLR jack is preferable, since it will deliver an electromagnetically cleaner signal. If required, both the balanced and unbalanced outputs
can be used simultaneously. If your system contains a CR77 or UM1 receiver, be sure to set its Audio Output Level switch correctly (see
pages 7 and 9 for details). Leave your amplifier (and/or mixer) off at this time.

7. Turn the Volume, Level or AF Level knob on the receiver completely counterclockwise. Connect the supplied AC adapter to the CR77
receiver and plug it in (the UM1 receiver can also operate off battery power or a 12 volt power supply from a connected video camera), then
plug the adapter into any standard AC outlet. Slide the Power switch in the direction of the arrow to turn on the receiver. If your system
contains a CR77 receiver, its "Power" LED will light steadily red. (Note: The UM1 receiver has no "Power" LED indicator.)

8. Turn on the power to your AH1 transmitter (using its Power on-off switch); the "Power/Battery" LED will flash if the battery is sufficiently
strong (if it lights steadily, the battery has less than 2 hours of power remaining and should be replaced). If your system contains either a
CR77 or UM1 receiver, one of the "A/B Receiver" LEDs will light, showing you whether the (left) "A" or (right) "B" receiver is currently being
used. The CR77 / UM1 meter will also indicate the strength of the incoming RF signal.

9. Now it's time to set the audio levels. Turn on your connected amplifier and/or mixer but keep its volume all the way down. Make sure
that the AH1 transmitter is unmuted (its Mute switch should be positioned away from the arrrow). Then set the Volume, Level or AF Level
knob on the receiver fully clockwise; this is unity gain.

10. Speak or sing into your headset mic (or play the instrument to which the horn mic is attached) at a normal performance level while
slowly raising the volume of your amplifier and/or mixer until the desired level is reached. The UM1 receiver allows you to monitor the
transmission signal using standard Walkman-type 30 ohm headphones connected to its headphone jack.

11. If you hear distortion at the desired volume level, first check to see whether the "Peak" LED on the receiver is lit . If it is not lit, make sure
that the gain structure of your audio system is correctly set (consult the owners manual of your mixer and/or amplifier for details). If the
"Peak" LED is lit, simply move the microphone further from your mouth.

12. Conversely, if you hear a weak, noisy signal at the desired volume level, again make sure that the gain structure of your audio system
is correctly set (consult the owners manual of your mixer and/or amplifier for details) and that the Volume, Level or AF Level control of the
receiver is fully clockwise. If it is and the signal coming from the receiver is still weak and/or noisy, simply position the microphone closer to
your mouth.

13. Temporarily turn down the level of your mixer/amplifier system and turn off the power to your transmitter, leaving the receiver on. Then
restore the previously set level of your mixer/amplifier. With the transmitter off, the receiver output should be totally silent-if it is, skip
ahead to the next step. If it isn't (that is, if you hear some noise), you may need to adjust the receiver Squelch control. When the Squelch
control is at its minimum setting, the AirLine system always provides maximum range without dropout; however, depending upon the particular
environment your system is used in, you may need to reduce that range somewhat in order to eliminate band noise when the AH1transmitter is turned off. To do so, use the provided screwdriver to rotate the Squelch control completely counterclockwise (to the "Min"
position), then slowly turn it clockwise until the noise disappears. If no noise is present at any position, leave it at its fully counterclockwise
"Min" position (so as to have the greatest overall range available).

Thank you and if you any more help let me know and don't forget to Rate

Still sounds like battery. Are you using alkaline batteries. Theres mic transmitters need a fair discharge rate whilst transmitting and maybe your current battery in not giving enough current.

it might possibly be the signal strength, try moving the transmitter closer, if possible.


Hope this helps!

A delay may be caused by interference from other radio sources. I heard of one case where a woman's cell phone call overpowered the transmit power of her baby monitor.

Other things that can cause interference or other receiver problems:
1. monitor in contact or close proximity to running appliances or their cords. (induced electromagnetic field)
2. neighbor with baby monitor on same channel ('cross-talk')
3. distance between transmitter and receiver too far (the strength of a radio signal fall dramatically over larger distances. think of how often you lose cell phone coverage)
4. reduced power: low battery strength or cooked power supply
5. transmitter or receiver insulated from signal (if your monitor was transmitting/receiving through any metal obstruction)
