Glensound Beatrice R4 4 Channel Network Audio Rackmount Intercom Glensound

The Glensound BEATRICE R4 is a robust, 4* channel 1RU rackmount intercom with crystal clear audio designed for broadcast, theatre 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 R4 is also fully compatible with other manufacturers’ equipment using the Dante protocol.

The Beatrice R4 is also AES67 compliant.

This small desktop unit was deigned to be very easy to use for the operator and simple to setup 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 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 l 

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 to. Twelve Volt Phantom power is also available and can be turned on/ off as required.

Intelligible Loudspeaker

What’s the point of an intercom unit if the onboard speaker is so cheap that you can’t understand what is being said to you? Glensound tried hundreds of different drive units before settling on the one used in the Beatrice R4. They chose it because it had a much cleaner sound and better frequency response for vocals than any other speaker on the market that would fit in a 1RU subrack.

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 Glensound’s unique headphone amplifiers are 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 the way on the rear panel.

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 it’s 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

Built to Last 

The Beatrice R4 is manufactured using lightweight but strong custom designed aluminium extrusions for the front and side panels and lightweight but strong extruded aluminium sheet for the lid and base. Front and rear panels are anodised and laser etched and side panels and lid/ base are powder coated in an aesthetically pleasing textured black powder coat.
