Williams AV DWS INT 3 400 ALK language interpretation system

General Description

The Williams AV Digi-Wave DWS INT 3 400 ALK is a completely portable wireless interpretation system for up to twenty listeners. Ideal when security, sound quality and flexibility are critical. Designed for medium size conferences, meetings or other events where delegates require language interpretation in one or two languages.

This system can be set two different ways:

One DLT 400 transceiver can be used as a body-worn transmitter to provide a direct audio feed from the speaker to the interpreter. The interpreter then uses the second DLT 400 transceiver to both listen to the speaker and transmit their simultaneous interpretation to the audience on a separate channel. The audience can choose to either listen to the interpreter or (if hard of hearing), the speaker on their receiver.

Alternatively, two interpreters can listen to the PA system or speaker directly and use both DLT 400 transceivers for interpretation. If both transceivers are set-up on the same channel, the interpreters can work together by ‘spelling’ each other, interpreting into the same language for long jobs. If the transceivers are set up on different channels, the interpreters can provide interpretation into two languages.

This system can serve up to twenty listeners. Additional DLT 400's can be purchased separately to accommodate up to 14 additional languages. Additional DLR receivers can be purchased separately to accommodate additional listeners. This system can serve an unlimited number of listeners within the recommended range.

Digital encryption and frequency-hopping technologies provide both secure and clear communication between the team. As the system can be used licence-free on all continents it is ideal for international travel.
