The Digi-Wave 400 Transceiver is a digital spread-spectrum (DSS) that can transmit and receive audio simultaneously. It operates in the 2.4 GHz band that offers a portable solution to assistive listening and interpretation applications. Its frequency-hopping algorithm allows the system to continuously switch frequencies, ensuring security and preventing interference.

The Digi-Wave 400 Transceiver allows users to listen and talk to one another wirelessly. It is compatible with the listen-only Digi-Wave 300 Receiver (with limited features) and Digi-Wave 400 Receiver. When pairing one or more Digi-Wave Transmitters and receivers, you can facilitate communication in scenarios such as guided tours, language interpretation, intercom communication, government sidebar communications, and more.
