    K380 VHF Wireless conference microphone

    The K380 professional wireless conference microphone is composed of quartz oscillation circuit, which has extremely high frequency stability; the multistage narrow band high-frequency filtering wave sufficiently eliminates disturbance signal. The conventional wireless microphone is made of silent circuit of low frequency, which analyzes strength of RF signal, so noise and signal required cannot be identified; when used under noisy RF environment (massive harmonic wave radiated by CD/VCD/LD and other digital devices), the silent circuit may be enabled accidentally with the transmitter signal weak or switched off and the receiver possibly cause strong blasting sound. 

    To solve this issue, the Company designs the professional wireless professional conference microphone. The multistage narrow band high-frequency filter creates a kind of digital noise inhibition circuit for high-frequency transmitting and receiving, which analyzes signal quality not signal strength. 

    When the transmitting signal is strong, the system noise sound 

    The illuminating ring of the sound head is on when the microphone is switched on.The microphone is installed with low-battery alert indicator.

    Standalone output and mix output functions are available and connected to mixer or power amplifier.

    Built-in Hi-Fi condenser sound head yields prime sound reproduction, high articulation and low noise.
