Common Evolution Wireless G4 errors & problems
What techs run into most, and what's usually behind it. The step-by-step fix for your exact unit is in Ask Roadie.
- Step-by-step fixGet the fix →
Audio cuts out / perceived dropouts even when the pack is close and battery is good
Likely cause: Squelch mutes the receiver whenever RF falls below its threshold.
- Step-by-step fixGet the fix →
Audio distorts / clips (AF Peak) at loud passages
Likely cause: Overdriving the transmitter input clips before RF transmission, so no amount of receiver-side adjustment removes it.
- Step-by-step fixGet the fix →
Interference, noise, or breakup on a channel, especially with multiple systems running
Likely cause: The 20 factory banks hold pre-coordinated, intermodulation-free frequency sets.
- Step-by-step fixGet the fix →
IR Sync fails - transmitter will not sync to the receiver
Likely cause: Sync is an infrared line-of-sight transfer of the receiver frequency to the transmitter.
- Step-by-step fixGet the fix →
Loud burst of noise / hiss through the PA when the transmitter is switched off or goes out of range
Likely cause: The G4 does not blindly mute on TX-off; it passes received RF.
- Step-by-step fixGet the fix →
Need to update firmware on a networked EM 300-500 G4 rack receiver
Likely cause: WSM pushes firmware over the receiver network port.
- Step-by-step fixGet the fix →
Not sure which channel/frequency a working system is on, or want to lock settings from tampering
Likely cause: The G4 stores frequency as bank+channel; syncing copies it TX<->RX.
- Step-by-step fixGet the fix →
Range is poor / dropouts as the performer walks the room
Likely cause: UHF at these frequencies is line-of-sight; bodies, metal, and RF-noisy LED/video gear absorb or reflect signal, and true-diversity only helps if both antennas have a clean path.
- Step-by-step fixGet the fix →
Receiver shows strong RF signal but there is no audio / output stays muted
Likely cause: The G4 pilot-tone squelch only unmutes when it detects the inaudible pilot tone the matched transmitter emits.
- Step-by-step fixGet the fix →
Short runtime / unsure how much battery is left
Likely cause: Alkaline AAs give the receiver only a rough voltage-based estimate, while the BA 2015 pack reports true state of charge - so accurate remaining-time only shows with the accupack.
