One-Way Digi-Wave Personal Communication System (Rechargeable)

This portable wireless intercom system facilitates one-way communication from a speaker (transceiver) to a listener (receiver), ideal for applications like assistive listening, interpretation, and guided tours. The Digi-Wave system is lightweight, portable, and secure, making it the go-to solution across various industries and scenarios, from classrooms to courtrooms.

Ensure Secure Audio – Our Digi-Wave systems feature a frequency-hopping algorithm to prevent interference, along with optional pin code access to prevent unauthorized users from eavesdropping. Whether it’s confidential discussions in boardrooms, legal proceedings, or other sensitive communications, your audio remains protected from unauthorized access where privacy is paramount.

Portable Convenience – This system is complete portability, allowing easy transportation and storage. The portable, lightweight transmitters, receivers, and accessories mean easy setup and operation, ensuring exceptional sound quality wherever you go.

Flexible Expansion – For larger gatherings or additional participants, you can easily expand the system by purchasing extra transceivers (DLT 400) and/or receivers (Rechargeable – DLR 400 RCH) (Alkaline – DLR 400 ALK), ensuring seamless communication in diverse settings such as factory tours, courtroom proceedings, or business meetings.
