Digital 220
Best for Q&A Tour
Interactive Guiding System
Being different from traditional one-way guiding system, we'd like to introduce our new two-way guiding system Digital 220.
Equipped with lightweight Digital 220, group guides and members can hear and be heard clearly regardless of noisy environments, such as public streets, large-scale factories, or crowded exhibitions.
Incorporated with inbuilt microphone, any group member can raise his or her question with a press of talk button. No more hesitation exists during your tour. Every group guide fully controls the talk right in the group and is free from “group chaos” for sure. Selectable HAC setting is useful for HAC users. Remote group-channel swift is beneficial to group guides who need to quickly find another channel if unexpected interference happens onsite.
There is no doubt that 120+ meter operating range (line-of-sight) and 25+ hour working time make Digital 220 be a great tool for any type of groups, like sightseeing tours, factory tours, enterprise training programs and so on. Even more, group members will never be missing as out-of-range reminder will be activated automatically whenever they stay further and are not in the transmission area of their guide.
Digital 220 is perfect for any application whenever two-way interaction is needed.
