| VK-9000 Product Description | |
| The industry's first patented technology for automatic human hand sensing, the microphone automatically silences within 3 seconds after leaving the hand and being stationary (can be placed in any direction or angle), automatically enters standby mode after 5 minutes of energy-saving, and automatically shuts down and completely cuts off the power after 15 minutes. It is a new concept of intelligent and automated wireless microphone | |
| A brand new audio circuit architecture, with delicate high notes and strong mid to low frequencies, especially in terms of sound details with perfect expressiveness. Superb dynamic tracking capability allows for easy pickup and playback at both long and short distances | |
| ◆ The brand new concept of digital pilot technology completely solves the phenomenon of KTV rooms crossing frequencies, never crossing frequencies! | |
| ◆ Equipped with howling suppression function circuit for easier debugging | |
| ◆ Automatic search for interference free channels for easier installation | |
| ◆ The maximum output volume can be freely limited, with a wider range of adaptability | |
| ◆ The host can flexibly set the usage frequency | |
| ◆ UHF frequency band, phase-locked loop (PLL) frequency synthesis | |
| ◆ 100 x 2 channels, with a channel spacing of 250KHz | |
| ◆ Ultra heterodyne secondary frequency conversion design with extremely high receiving sensitivity | |
| ◆ The RF part adopts multi-stage high-performance dielectric filters with excellent anti-interference ability | |
| ◆ The first intermediate frequency adopts a sound table filter, and the second intermediate frequency adopts a three-stage ceramic filter, which greatly improves the anti-interference ability | |
| ◆ Specially designed mute circuit, completely eliminating the impact noise of microphone on and off | |
| ◆ The microphone uses an Easybuy No.5 battery, which can last for 6-10 hours | |
| ◆ The microphone adopts a unique boost design, and the decrease in battery level does not affect the overall performance of the handheld microphone | |
| ◆ Ideal operating radius of up to 80 meters, suitable for various requirements | |
| ◆ The default configuration is a microphone tube with a blue backlight on the LCD screen and an aluminum alloy body | |
| ◆ Equipped with adjustable transmission power and adjustable squelch threshold, the receiver rear panel is equipped with an external squelch control knob, which can flexibly set the effective operating radius between 10 meters and 80 meters as needed | |
| ◆ Equipped with infrared automatic frequency matching function, it can quickly synchronize the microphone to the working channel of the receiver | |
| ◆ KTV engineering specific model, two microphones, one host. Easy configuration of over 100 KTV rooms, unique product structure design, fast and easy maintenance. | |
