Slim, and easy to use, the DigiWave DLT 400 Transceiver from Williams AV is a pocket-sized unit that enables simultaneous listening and broadcast, so that your  translator or interpreter can listen to the proceedings, and send a translated language feed to listeners at the same time.

As part of a larger system, additional DLT 400’s can be combined to in one-way mode to add language interpretation support for up to 14 total language interpretation feeds.

The DLT-400 transceiver can broadcast to an unlimited number of listeners within a 900 foot indoor range while providing a crystal-clear signal. Using a frequency-hopping algorithm called digital spread-spectrum (DSS), there’s less worry about interference issues and provides a more secure broadcast. Transceivers can be used for both indoor and outdoor events.

Whether communicating to students in a school assembly or parents in a PTA meeting, speaking to a group on a factory tour or delivering a sermon to a bi-lingual audience, the DLT-400 has you covered and it’s easy to use!

In most cases, there’s no need to have a dedicated audio technician running your gear.
