The Glensound Beatrice W4 is a single user interface for the Beatrice system, designed to mount flush on a wall or into a desk. It is a useful intercom position, allowing two-way communication to be possible at standing levels whilst mounted on walls, or at desk level if mounted on a desk.
This device uses Audinate's Ultimo Chipset, which can receive 4x incoming audio channels, each at 48kHz. However, this chipset can only receive these 4x audio channels from a maximum of 2x network locations (2x different devices). This is common with any manufacturer that uses this chipset.
