Product Features

This series of walkie talkies is suitable for workplaces with certain sound insulation environments, achieving bidirectional fully automatic switching of voice communication. It adopts professional and unique technology, with excellent quality requirements, to enable the best voice communication between tellers and customers.

The thick space aluminum alloy is used as its shell to avoid the phenomenon of box resonance. The professional acoustic design of the sound system ensures high fidelity sound quality at the level of a speaker, with clear and realistic sound.

The unique audio automatic switching circuit and automatic noise cancellation circuit achieve automatic channel control and noise suppression, fundamentally preventing the phenomenon of self-excited noise caused by acoustics and electricity. It ensures that the walkie talkie can work stably for a long time in any environment with certain sound insulation between the main and auxiliary units.

Uninterrupted provision of recording signals. As long as you do not unplug the power plug of the machine, whether you turn down the volume to the minimum or turn off the power switch, the walkie talkie can continuously output recording signals of the same size. This signal source can be connected to the monitoring system for use.

High sensitivity pickup range. As long as the straight-line distance between you and the machine is within50cmBetween them, your voice signals can be fully picked up and transmitted to the other party.

This walkie talkie adopts a unique circuit and design. Only one party can speak at the same time, and the other party who speaks later will not be allowed to talk. This ensures that both parties can hear each other's expressions clearly, avoiding unnecessary trouble.
