Wireless Audio Dropouts or Cutting Out
Dropouts (sound cutting in and out) usually come from the radio link, the battery or the mic cable.
Does it happen in one spot, or when the performer moves?
- In certain spots on stage: a radio-signal problem. See the RF checks below.
- When the performer moves their head or body: likely the mic cable or connector. Wiggle the cable near the plug and capsule while listening. Crackling points to the cable. See Replacing a broken mic cable.
- Gets worse during the show: likely batteries. Use fresh ones.
Radio-signal (RF) checks
- Make sure antennas are attached, upright (or paddles aimed at the stage), and have clear line of sight to the stage.
- Move receivers or antennas out of closed racks, booths with metal walls, or areas behind the proscenium.
- Keep the bodypack's antenna straight and uncovered; don't fold it or wrap it in tape.
- Re-scan for clear frequencies with all show equipment turned on, and check no two packs share a frequency.
- Move receivers and antennas away from LED walls, video gear, dimmers and Wi-Fi routers.
- Check that spare transmitters in dressing rooms are turned off or on their own coordinated frequencies.
Sweat
Sweat getting into the connector or pack can cause intermittent sound. Use sweat protection and let equipment dry between shows. See Caring for body-worn microphones.
