Williams Sound Tour Systems

Everyone Gets a Voice.

Choose Digi-Wave 4.0 from Williams Sound when you need two-way, collaborative communication. With Digi-Wave, your tour can be led by up to two guides or interpreters. Plus, guests can ask a question or interact with other tour members with just the push of a button.

Stop yelling. The Williams Sound system is ideal for management teams, engineering workgroups, and customer prospect tours in noisy environments. Improve tour safety, reduce ambient noise, and hold sensitive discussions at a quieter, conversation level.

Multiple messages? Hold side-by-side presentations without interference. In two-way or one-way mode, the Digi-Wave system allows tour hosts to operate in the same area in full-duplex mode, simultaneously with no cross-talk.

NEWEST Digi-Wave 4.0 version delivers:

  • Programming Ease of Use
  • Updated Wireless Charging
  • Backwards Compatibility with Digi-Wave 3.0
