General Description

The Williams Sound Digi-Wave DLT 400 features full-duplex capability, supporting up to four simultaneous talkers in tour guide mode, and up to six simultaneous talkers in intercom mode. One or two-way operation offers flexibility in an array of applications. With the push of a button, users can access two-way communication for immediate interaction or Q&A.

The Digi-Wave system is ideal for guided tours. The tour guide can address the tour group whilst walking around. The tour guide can allow guests to talk back when required. Another common application is for staff meetings on the move.

The Digi-Wave system enables up to six people to talk in open ‘full-duplex’ communication, as if on the same telephone call. With a wide range of headsets available, the Digi-Wave tour guide system is suitable for any environment from a quiet tour around a historic site to a noisy manufacturing site where hearing protection is required.

The DLT 400 is backward compatible with the previous generation DLT 300 transceiver and DLR 360 receiver (with some limitations).
