Audio Guides are a multi-lingual, multi-content playback device that offers museums, art galleries, and other cultural attractions the ability to entertain, teach and engage visitors by delivering the right information at the right time and place…seamlessly.

RF Beacons create seamless content triggering. Audio content can be automatically played when a user comes within the range of an RF Beacon.  Audio tracks and audio track images along with language images can be downloaded to the device using the free Audio Master 3 software.

Each unit has a built-in rechargeable lithium battery and speaker.  There are also two headphone jacks allowing two users to listen per device.  A front OLED display features status information, language, and audio track information and will display audio track images, helping to enhance the visitor experience.  Multi-unit chargers are available to help make pickup and return easily managed and keep each unit fully charged.

From Museums to science centers, zoos to aquariums, and more, the AT200 Audio Guide family makes an outstanding choice for an exceptional visitor experience, keeping the focus on the attraction and not the device.
