Williams Sound Digi-Wave 400 Series Preliminary Manual

PRELIMINARY MANUAL
Digi-Wave
Digital Transceiver and Receiver

System Overview

The Digi-Wave communication system allows users to listen and talk to one another wirelessly in a variety of scenarios.
A Digi-Wave system consists of at least one transceiver (DLT 400) and various combinations of transceivers and
receivers (DLR 400).
The DLT 400 is a two-way transceiver, meaning that it can transmit and receive audio simultaneously.
The DLR 400 is a receiver only. Users of DLR 400 receivers can only hear what is being broadcast by DLT(s); they
cannot create any audio. There are two models of DLR: the DLR 400 ALK and the DLT 400 RCH.
