Orpheo TourGuide (OTG) is a new generation tour guide system with the utmost flexibility.
As such, each device can be switched into either transmitter or receiver mode by tour operators at the start of each tour.
OTG is a wireless tour guide system which allows visitors to stand away from the tour guide without compromising reception quality. This is a crucial factor for large tour groups. The transmission capability is around 100 meters.
This new tour guide system, designed and manufactured by Orpheo, functions with digital technology.

Accessories

For visitors

For tour leaders

group tour guide system accessory supra-aural earphones

Supra-aural mono earphones

The supra-aural mono earphones we supply are reusable and can be cleaned simply and quickly with disposable disinfectant wipes (the earphones have no contact with the internal ear). Mono earphones can be beneficial as they enable the user to listen to the commentary but still be available to other group members in their surroundings when desired.

group tour guide system accessory headphones

Headphones

For noisy environments (factory tours with machinery, for example), we recommend the use of headphones. We also offer disposable covers for hygienic purposes.

Orpheo Tour Guide dual jack output downsized and optimized

2 audio outputs

Thanks to 2 audio jacks, Orpheo TG enables 2 people to use the same receiver at once. This can be invaluable during special events with extra visitors, for example.

It also allows family members, a companion or a visually impaired visitor to share a device.

Autonomy and charging racks

The devices function with Li-ion batteries.
The autonomy is 50 hours when operating in receiver mode and 20 hours in transmitter mode.
A battery level indicator shows continuously on the screen showing the number of hours available for use.

The OTG charging racks come with 24 slots enabling battery recharge as well as modification of the settings on the players.
There are 3 different styles available:

  • Suitcase format with lid and carrying strap
  • Standard 19″ rackable format (4U)
  • Free-standing rack with optional wall hooks

Capability of configuring 23 devices at once:
