Williams AV DLT 400 Digi-Wave Transceiver

Williams AV DLT 400 Digi-Wave Transceiver - The Digi-Wave™ system is a two-way wireless digital listening system with extended digital spectrum (DSS). Using its frequency-hopping algorithm, it avoids interference and is a very secure communication method. The Digi-Wave communication system allows users to listen and speak to each other wirelessly in a variety of scenarios.

Excellent for use during training, presentations, and tours, especially in places of worship, classrooms, and healthcare facilities.

The system includes:

The DLT 400 has an internal rechargeable battery and includes the DW ACC PAC4 charging pack.

Features:

A Digi-Wave system consists of at least one transceiver (DLT 400) and various combinations of transceivers and receivers (DLR 400 RCH or DLR 400 ALK). Combinations of one or more DLTs and DLRs can be used to facilitate different events, depending on what needs to be spoken and what needs to be heard. Typical scenarios include:

• Guided tours – with one or more tour guides (two-way), with audience participation (two-way) or without audience participation (one-way)
• Language interpretation – one or more interpreted languages transmitted to the audience (one-way)
• Intercom – with up to six people able to speak simultaneously and listen even more
• Hearing assistance – with enhanced sound for improved understanding
