ES-10 Product Drawing
ES-10 Product Description
The ES series adopts world-class speaker units and lightweight imported birch wood panels. Through computer design, it has precise frequency division and broadening frequency response characteristics, as well as good control coverage performance. The rotatable compression horn allows for both vertical and balanced installation, with smooth frequency response and precise division to ensure excellent sound quality for listeners. Simply using language sounds is more ideal. High end bars and slow bars require a balance between smooth and wide vocal ranges. Overly exaggerated and turbid sound quality characteristics are not durable. Especially for slow bars and bars, the sound system must provide smooth and strong bass to replay these music. The ES series uses computer design to set the mid to high frequencies in areas that require impact and high-power treble, expanding the best vocal performance.

◆ The industry's first automatic hand induction patented technology, the microphone is automatically muted within 3 seconds after leaving the human hand (any direction, any angle can be placed), 5 minutes after the automatic energy saving into standby state, 15 minutes after the automatic shutdown and completely cut off the power supply, is a new concept of intelligent, automatic wireless microphone
◆ Brand new audio circuit architecture, delicate treble, strong middle and low frequency, especially in the details of the sound has perfect expressiveness. The super dynamic tracking ability makes it easy to pick up and play sounds at far/short range
◆ The new concept of digital pilot technology completely solves the phenomenon of cross-frequency in KTV private rooms, and never cross-frequency!
◆ Equipped with acoustic noise suppression function circuit, debugging is simpler
◆ Automatic search for interference-free channel function, more convenient installation
◆ The maximum output volume can be freely limited, and the adaptation range is wider
◆ The host can flexibly set the number of uses
◆ UHF band, phase-locked loop (PLL) frequency synthesis
◆ 100×2 channels, channel spacing 250KHz
◆ Superheterodyne secondary frequency conversion design, with extremely high receiving sensitivity
◆ The RF part adopts multi-stage high-performance dielectric filter, which has excellent anti-interference ability
◆ The first intermediate frequency adopts an acoustic surface filter, and the second intermediate frequency adopts a three-stage ceramic filter, which improves the anti-interference ability
◆ Specially designed mute circuit to completely eliminate the impact noise of microphone opening and closing
◆ The microphone uses easy-to-buy No. 5 batteries, and the reuse time is 6-10 hours
◆ The microphone adopts a unique boost design, and the battery power drop does not affect the overall mold of the hand
◆ The ideal environment operation radius is up to 80 meters, which is suitable for various requirements and occasions
◆ The default configuration is a microphone tube with LCD screen blue backlight and aluminum alloy
◆ With adjustable transmit power and adjustable noise threshold, the rear panel of the receiver is equipped with an external noise control knob, which can flexibly set the effective operating radius between 10 meters and 80 meters according to the needs
◆ With infrared automatic linking function, the microphone can be quickly synchronized to the working channel of the receiver
