Wireless Microphone
Microphone power consumption: 80mA, powered by 2 pieces of 1.5V batteries, with up to 12 hours of continuous operation. Operating distance: 80–100 meters in open areas, 50–80 meters in complex environments. Suitable for various conferences and speaking occasions.
UHF band, frequency range: 500MHz–900MHz.
Dual-channel signal reception, 200 selectable channels per channel with 250kHz stepping; 49.75MHz for each channel.
Adopts stable PLL digital phase-locked loop synthesis technology
Supporting simultaneous use of up to 40 units (i.e., 40 receivers and 80 transmitters).
Built-in high-efficiency noise suppression circuit with outstanding anti-howling function.
Support 2 balanced outputs and 1 mixed unbalanced output, suitable for connecting various external devices.
The same transmitter can work interchangeably across 400 channels in two channels
Ultra-quiet tactile switch; press and hold for 2 seconds to power on and enter operating mode.
Equipped with RF power selection, allowing users to choose Hi or Lo mode according to the actual environment.
Selecting Lo mode reduces battery consumption, extends operating time, and minimizes interference with other frequency transmission and reception.
