Williams AV DLR 400 RCH Digi-Wave Receiver

Williams AV DLR 400 RCH Digi-Wave Receiver - The Digi-Wave™ system is a digital wireless listening system in two channels, 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 medical assistance units.

The system includes: DLR 400 has a built-in rechargeable battery.

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), involving the audience (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
• DLR 400 RCH is rechargeable. If alkaline batteries are preferred, refer to DLR 400 ALK.
