Audio AU400 Pro UHF 4 Channel Wireless Microphone System with Cordless Handheld Lavalier Headset Mics, Metal Receiver, Ideal for Karaoke Church Party (with 4 Bodypack (B))

AU400 4 channel wireless microphone system.
(Two set frequency points: A- 501/ 511.5 /524/ 538.5 B-506/ 517.5 /531/ 546.5 ) This series utilizes UHF frequency and operates on the internationally standardized common frequency for global application. Conventional wireless microphones are frequently subject to interference from multiple factors, particularly from harmonics generated by CD/DVD/VCD/LD and other digital devices. Squelch circuits generally assess the intensity of the RF frequency channel instead of differentiating between noise and the intended signal. In complex settings, or when the microphone signal is faint or the microphone is enclosed, employing conventional wireless microphones might cause the squelch circuit to activate abruptly, leading to the receiver outputting a powerful burst of noise. It is well-suited for church services, small DJ/KJ stages, birthday or wedding parties, family gatherings, conferences, classrooms, and small karaoke nights
