Wireless One-to-Two Handheld Microphone

◆ Built-in 3-group frequency stacking, one-key retrieval. Three sets can be easily stacked and used simultaneously on the same frequency band.◆ Equipped with IR infrared automatic frequency matching function, one-key automatic frequency lock.◆ Independent volume adjustment for two channels. Provides 2-in-1 audio output. Each channel's audio volume output can be controlled independently.◆ Offers a variety of transmitter options. Conference/handheld/lapel transmitters can be mixed and matched without interference.◆ Backlit LED display indicates RF and AF signal strength, frequency, frequency group/channel, and other working status.◆ Uses the same working frequency for two channels, allowing transmitters to be exchanged at any time, greatly enhancing operational flexibility.◆ Uses the latest UHF band wireless audio transmitter chip module IC. Features excellent RF and audio performance, providing customers with professional-grade sound quality experience. With noise lock and digital pilot technology, when the transmitter is turned off, the pilot control mutes the AF signal to suppress noise and mutes the corresponding channel on the receiver, ensuring effective isolation from interference signals.U-section PE shell transmitter:Frequency range: 640MHz-695MHzFrequency locking: PLLFrequency stability: ±0.005%Audio dynamic range: ≧102dBAudio frequency response: 30Hz-18kHzTotal harmonic distortion S/N ratio: <-60dBcRF transmitter output: 10mWOperating current: <100mABattery: AA 1.5V × 2Receiver:Frequency range: 640MHz-695MHzFrequency stability: ±0.005%Image frequency rejection: >80dBS/N ratio: >105dB (1kHz)Sensitivity: -107dBmOutput impedance: 600ΩAudio output level: -12dBPower requirements: DC 12–18.5V 500mA
