MAIN FEATURES

AU+ series UHF wireless microphone system features

● Can be used with handheld, lavalier, or headset microphones as needed. This series uses the UHF band, an internationally recognized standard, and can be used globally. Multiple built-in channels can be switched to avoid interference sources when signal interference is detected.

● Squelch circuits typically analyze the strength of the RF channel, not the noise and the desired signal. When traditional wireless microphones are used in complex environments, or when the microphone signal is weak or the microphone is off, many squelch circuits will suddenly activate, causing the receiver to emit a loud burst of noise.

● Suitable for churches, small DJ/KJ stages, birthday parties, weddings or family gatherings, meetings, classrooms, small karaoke nights, etc.
