Thank you for your inquiry. There are many causes of drop outs, but it is most often caused by some type of radio frequency interference (RFI). Check for TV channels in your area that are operating on the same frequency as your wireless system. Browse our web site at www.audio-technica.com
for the tool "Selecting A-T Frequencies" to help determine the channels that are operating in your area. Make sure that your receiver is not close to any digital equipment such as digital effects units, CD players, A/D converters, computers and so on. These devices are known to cause problems with wireless systems. One way to check for RFI is to turn on all of your equipment, except for the transmitter, and watch the RF indicator on your receiver. If the RF indicator is registering a signal, then you are picking up RFI and will need to identify the source. Also, check the squelch setting on your receiver. The squelch circuitry helps to filter out unwanted RFI, but if it is set to tight you could be filtering your own signal, thus limiting your distance. Please note that if you are using multiple systems you will also need to choose frequencies that are compatible with each other. You should consult your user’s guide for a list of compatible frequencies. Finally, make sure that you have a clear line of site between the transmitter and the receiver. If you are still having issues, please contact our Audio Solutions team at (330) 686-2600 ext. 5000 and they can help.
Check the RF power switch (also called Battery Save switch) on your transmitter. It should be set to high power. If it is set to low power you could be loosing distance. Finally, make sure that you have a clear line of site between the transmitter and the receiver.
