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.
PLEASE NOTE THERE IS A LIMITATION TO INCOMING NETWORK STREAMS SEE ‘*’ IN SPECIFICATION.

Dante Routing & Partyline
Audio routing to/ from other devices is setup using 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 4 incoming circuits to be routed to any of the 4 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 two 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? We use high output, high quality, large magnet Visatron speakers with excellent voice intelligibility to make communication straightforward and easy to understand.

Volume, Panning & Incoming Levels
The front panel features an easy to use volume/ setup control. This multifunctional control provides day to day operational control of:
A) Overall volume control (just turn the knob)
B) Incoming channel level (push the speak key and turn the knob simultaneously)
C) Panning (push the speak key and push and turn the knob simultaneously)

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
One of our unique headphone amplifiers is fitted to the Beatrice D4. These allow either low or high impedance headphones to be used and automatically adjust the output level to match the impedance of headphones in use. The headphone amplifier is stereo and sources can be panned to 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.

Headset Connector
If you prefer an intercom headset with a single XLR connector for microphone and headphones, then fitted as standard to the rear is a 5 pin female XLR headset connector. The microphone input on this headset connector is in parallel with the 3 pin XLR and the headphone output is in parallel with the 6.35mm TRS jack.
A 4 pin male XLR can be fitted to special order instead of the 5 pin female headset connector.

Call Function
A simple call function is inbuilt allowing the operator of one unit to call/alert other users that they want to communicate with them. To call another user the operator double taps the speak key of the channel they want to call, this then flashes a bright yellow call LED on the other users keypanel, which continues to flash until the call is answered. As well as flashing a LED at the receiving end of the call an audible ‘beep’ can be set to alert the user that an incoming call has been placed to them.

Display for Setup
To make setup of the unit easy and intuitive a display is provided on the front panels. This display provides a simple menu system for setting up such items as: Button Configuration, Input Type (Mic/ Line), Microphone Gain, Phantom Power On/ Off, Sidetone Level (Own voice in own headphones), Partyline/ Loop Through, Mode Mixing/ Cutting of Partyline when User Speaks.

Presence Indicator
Each channel has its own red LED that acts as a presence detector on the incoming audio circuit. When audio is detected the LED is lit and it stays lit for a short period after the incoming audio stops.

Small and Robust
The Beatrice D4 is manufactured using lightweight but strong aluminium. It has laser etched aluminium front & rear panels and powder coated aluminium sides. The form factor has been carefully designed to be as small as the internal electronics allow whilst keeping user buttons, microphone and loudspeaker ergonomically positioned for optimum user experience. Weighing in at just 1.5Kg it is light enough to transport easily but heavy enough to stay put on a busy desk or work surface, and at just 214 x 172 x 41mm it won’t get in the way.

FOUR INCOMING AUDIO CIRCUITS
