 Vice machine using a wide caliber design, host a large speaker, the sound is more loud and clear. Particularly applicable to railway stations and other space, the flow of people and more places. 
 ● the use of thick aluminum alloy of the space as its shell, to avoid the phenomenon of cabinet resonance, professional audio acoustic design, the sound quality of speaker-level high-fidelity, the sound is clear and realistic. 
 ● unique audio automatically switch circuit and automatic noise elimination circuit to achieve automatic control and noise suppression of the channel, fundamentally prevent the sound of electricity caused by the self-excited whistle. Ensure the walkie-talkie as long as any long-term stable environment can work a certain noise between the main and auxiliary machinery. 
 ● to provide uninterrupted recording signal. As long as you are not pulled out the power plug of the machine.
