Can I use several WASP270L at an outdoor event within 50 ft from each other? Will there be interference if we use wired mics?
Asked by: Lynn
The Technical Pro WASP270L Rechargeable Portable Speaker with Wireless UHF Lapel Microphone operates on a narrow UHF band, so interference is very likely if multiple units are used in close proximity. Ultimately, results may vary when using the wireless microphones based on the location, environment, and any obstructions. There should be no problem with interference if using the WASP270L with wired microphones instead of the wireless mics.
