One Dray Two Wireless Microphone VS-300

◆ The industry’s first patented automatic hand sensing technology. The microphone automatically mutes within 3 seconds after it leaves the human hand and is stationary (can be placed in any direction and at any angle). It automatically saves energy and enters standby mode after 5 minutes. It automatically shuts down and completely cuts off after 15 minutes. It has a floor-standing mute function and is a new concept of intelligent and automated wireless microphone.It is a new concept of intelligent and automated wireless microphone
◆ Brand-new audio circuit architecture, delicate treble, strong mid-low frequency, especially perfect expression in the details of the sound. Super dynamic The tracking ability makes it easy to pick up and release sounds from far and near distances
◆ The new concept of digital pilot technology completely solves the problem of cross-talk between KTV rooms and never cross-talk!
◆ Equipped with a howling suppression function circuit, making debugging easier
◆ Automatic Interference-free channel search function makes installation more convenient
◆ The host can flexibly set the number of uses
◆ UHF frequency band, phase-locked loop (PLL) frequency synthesis
◆ 100×2 channels, channel spacing 250KHz
◆ Superheterodyne secondary frequency conversion design, with extremely high High receiving sensitivity
◆ The radio frequency part uses multi-stage high-performance dielectric filters, which have excellent anti-interference capabilities
◆ The first intermediate frequency uses a surface acoustic filter, and the second intermediate frequency uses a three-stage ceramic filter, which greatly improves the anti-interference ability Capabilities
◆ The specially designed mute circuit completely eliminates the impact noise when the microphone is turned on and off
◆ The microphone uses Tesco’s AA battery, which can last up to 6-10 hours
◆ The microphone adopts a unique boost design, and the battery power drops will not affect the hand Overall performance of the microphone
◆ The operating radius of the ideal environment is up to 80 meters, suitable for various demandin
