UHF Dual Channel Wireless Microphone

Audio Systems / Microphones

UHF Dual Channel Wireless Microphone

Code: EC-89U/WM-89B

Uses UHF 600-900MHz frequency band to avoid interference frequencies. Employs multiple narrowband high-frequency and mid-frequency selective filtering to effectively eliminate interference signals. Handheld microphone includes a low battery indicator circuit to prompt battery replacement. Special half-muted audio shock wave elimination circuit in the handheld microphone. Quartz oscillation circuit throughout, ensuring extremely high frequency stability. Adopts audio compression-expansion technology to significantly reduce noise and increase dynamic range. Equipped with feedback suppression to effectively reduce feedback squeal. Unique noise squelch function to reject external interference by activating the system’s mute feature. Selects high-quality chips and components to deliver exceptional sound quality. Features independent balanced output and mixed output, compatible with mixers and amplifiers. Maximum open space usage distance of 80 meters. Suitable for various applications such as large and small stages, dance halls, conference rooms, churches, lectures, KTV rooms, and home entertainment.
