12 Questions to Ask Before Booking Wireless Audio Systems Services

Why Wireless Needs a Plan Wireless microphones and in-ear monitors share radio spectrum with every other wireless system in and around the venue. When that spectrum isn't planned, the result is dropouts, noise, or a presenter who goes silent mid-sentence. The questions below help you work out what an event actually needs before you book equipment and crew. 12 Questions to Ask Before Booking Wireless Audio 1. How many wireless channels do we need at the same time? Count every microphone and in-ear pack that will be live simultaneously, including presenters, panelists, performers, and hosts. Channel count drives almost every other decision. 2. Who is doing frequency coordination? Someone needs to scan the venue and assign compatible frequencies to every channel. Ask who that person is and when the scan will happen. 3. What are the RF conditions at this venue? Dense city venues, broadcast neighbors, and other events in the same building can crowd the spectrum. The venue or its in-house AV team may know about common problems. 4. Are other groups using wireless in the same space? Other stages, rooms, broadcast crews, or venue systems may be running wireless too. Coordination only works when all of them are included. 5. Which microphone types suit each person? Handhelds, lavaliers, and headset mics each have trade-offs in sound quality, visibility, and how easily a presenter can use them. Match the mic to the person and the content. 6. Where will receivers and antennas be placed? Receivers work best with antennas that have a clear line of sight to the stage. Placing them behind a wall or in a closed rack far from the stage invites dropouts. 7. Is antenna distribution needed? Larger channel counts usually call for antenna distribution rather than separate antennas on every receiver. Ask how the system will be set up for the channel count you need. 8. What is the plan if interference shows up? Ask whether backup frequencies are coordinated and ready, and how quickly a channel can be moved during the event. 9. What is the battery strategy? Decide whether transmitters use fresh disposable batteries or charged rechargeables for each session, who swaps them, and how battery levels are monitored during the show. 10. Is the equipment compatible with the rest of the system? Confirm that wireless receivers connect cleanly to the mixing console and that any rented equipment works with the venue's system or a performer's own gear. 11. When is sound check, and who needs to attend? Every presenter or performer on wireless should be checked with their actual mic and position. Build time for this into the schedule. 12. Will a wireless technician be on site for the whole event? Wireless problems usually need fixing within seconds. Ask whether a dedicated technician (often an A2) will be monitoring RF and handling mic changes throughout the show, not just during setup. Crewing Wireless Audio For events with many wireless channels, an A2 or RF-focused audio technician usually handles coordination, mic placement, and battery changes while the A1 mixes.
