Digi-Wave Language Interpretation System

Product Highlights

  • Multiple interpreters/listeners
  • Full day use — single charge


The DWS INT 5 PRO is a completely portable, wireless, single-speaker plus 4-language interpretation system. Ideal for up to four languages, plus floor.  Up to 50 listeners.  Space for up to 70 receivers per tray.  Ideal when security, sound quality and flexibility are critical. Designed for small - to medium-size conferences, meetings or other events where one language is shared by four interpreters. System can serve up to 50 listeners. Additional DLT 100 2.0's can be purchased separately to accommodate up to 14 additional languages. Additional DLR 60 2.0's can be purchased separately to accommodate additional listeners. Can serve unlimited number of listeners within recommended range.

DWS INT 5 PRO is ideal for a one floor / four interpreter scenario:
One DLT 100 2.0 transceiver is set up as body-worn transmitter to provide a direct audio feed from a speaker to four interpreters. Interpreters 1, 2, 3 and 4 then use DLT 60 2.0's to both listen to the speaker and transmit their simultaneous interpretation to the audience on 4 separate channels.  The audience, using DLR 60 2.0's, can tune in any of these channels (they can toggle back and forth between CH 0 for floor speaker and CH 1-4 for interpreted languages).
