Top Wireless Performance

Five Troubleshooting Tips

  1. Gain set-up is crucial for the proper operation of the wireless transmitter.Handheld transmitters can be overdriven by a vocal presenter if the gain is set too high and under-driven if the gain is set too low. Both situations can lead to poor results.

    Always try to adjust for the talent of the day – not all talent are the same; some sing or speak softly requiring more initial gain and others are very loud and require minimal gain. Body-pack transmitters are frequently used with guitars that have a higher output and therefore require less gain (or more pad).

  2. Use fresh batteries with a full charge for each event.Using rechargeable batteries is a great way to save money and landfills as long as you or someone on your staff is able to effectively manage them. Remove batteries from transmitters after each performance. This will keep you from using half-dead batteries the next time you need them and will also prevent an accidental leak from damaging your transmitter if stored for an extended period of time.
  3. Make sure that you have chosen a clean frequency in which to operate your wireless system.You can use the frequency calculator on Shure’s website to help determine which TV channels to avoid. If you still have questions, Shure’s Applications Engineering Group is glad to help.
  4. Antenna placement and set-up is important.Try to keep antennas as close to transmitters with line of sight as is possible. Antennas can also be frequency band specific – don’t try to use an antenna from another system without double-checking the frequencies first.

    Never let antennas touch one another. If you are using more than one wireless system, make sure you leave at least a foot between antennas from different receivers.

    Make sure all connections are solid. For antennas, double-check the center pin on the BNC connectors to make sure it isn’t bent or broken. If you need to remotely locate an antenna, be sure to use the correct cable – not all coax cable is the same. Cable used for television will not perform the same as cable designed for use with antennas. Consult the Shure website or tech support group for assistance in picking the right product for your application should you have any questions.

  5. It is important to dry and clean off the body pack before storing.Many times a body pack transmitter can get wet from a performer (sweat). Using a hairdryer (set to low or no heat) is a great way to speed up the process. Storing bodypacks with silica gel desiccant packets also works well.
