The Glensound Beatrice D4 is a robust, four-channel desktop intercom with crystal-clear audio designed for broadcast, theater, and professional audio applications. It is part of the 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 D4 is also fully compatible with other manufacturers’ equipment using the Dante protocol. The Beatrice D4 is also AES67 compliant. This small desktop unit was designed 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.
4 Channels
One single user connected to the unit can listen to and communicate with 4 separate locations on the network. Depending upon how the Dante network has been routed, the incoming audio circuits and outgoing circuits can be different locations.
Dante Routing & Partyline
Audio routing to/from other devices is set up using a Dante controller, which allows for point-to-multipoint routing on outgoing circuits (but only 1 single incoming circuit for each of the 4 channels). An inbuilt partyline facility allows any of the 4x incoming circuits to be routed to any of the 4x output circuits, making both simple partyline and more complex group circuits easily configured.
Onboard Mic & External Mic Input
A good quality, clear-sounding microphone amplifier, designed for communication purposes, is fitted, which also has the benefit of a compressor/limiter circuit to help keep levels and intelligibility consistent even when the operator gets overly excited. This microphone amp has 2x microphone sources, either the inbuilt front panel mounted electret capsule which provides good voice intelligibility from normal working distances, or a balanced XLR input for connecting external gooseneck microphones. Twelve-volt phantom power is also available and can be turned on/ off as required.
Large Diameter Visatron Loudspeaker
What’s the point of an intercom unit if the onboard speaker is so small and cheap that you can’t understand what is being said to you? Glensound uses high-output, high-quality, large-magnet Visatron speakers with excellent voice intelligibility to make communication straightforward to understand.
Mains or PoE Powered
An inbuilt wide-range switch-mode mains power supply is fitted for powering the Beatrice D4. It is terminated with a standard IEC plug, making it easy to plug in wherever you are in the World. It can also be powered via the Ethernet cable by standard PoE (Power over Ethernet), which can be supplied by an external PoE switch or a midspan power injector.
Headphone Output
A unique headphone amplifier is fitted to the Beatrice D4. This allows either low- or high-impedance headphones to be used and automatically adjusts the output level to match the impedance of headphones in use. The headphone amplifier is stereo and sources can be panned to the left or right ears as desired. The unique headphone amplifier can also drive mono earpieces from its stereo output without any performance issues. Headphone connection is via a standard 6.35mm TRS jack socket located out of the way on the rear panel.
