The Glensound BEATRICE B4 is a robust, 4* channel beltpack intercom with crystal clear audio designed for broadcast, theatre and professional audio applications.

It is part of Glensound’s Beatrice intercom system that utilises the reliable and proven Dante network audio transmission protocol to allow real time distribution of uncompressed audio across standard networks. As such the BEATRICE B4 is also fully compatible with other manufacturers’ equipment using the Dante protocol.

The Beatrice B4 is also AES67 compliant.

This small desktop unit was deigned to be very easy to use for the operator and simple to set up for the technician. It includes all the basic functionality required for small intercom systems and none of the overly complex installation requirements normally associated with large systems.
