OVERVIEW
The Glensound BEATRICE MIX32 is a high-density audio mixer for producing fixed
ratio audio mixes from/ to Dante® and AES67 audio networks. It can be fitted with a
maximum of 4 independent mixer cards each with their own redundant network
interface. Each of these mixer cards provides 32 audio inputs and 32 audio outputs
from the network with the 32 outputs being mixes derived from different sets of input
channels.
Audio limiter/ compressor circuits are also provided for each output.
The fixed ratio mixes in the Beatrice MIX32 were originally designed to allow network
audio intercom systems to generate multiple listening circuits however the high-
quality low noise digital mixers can be also be used for many other applications.
The Beatrice MIX32 can also operate in a ‘pass through’ mode where all Dante®
inputs are passed straight through to the equivalent numbered Dante® output.
A clean feed or mix-minus mode is also available. In this mode each mix has
multiple outputs. Each output contains all channels in the mix except its own input.
Being designed for 24/7 broadcast operation the Beatrice MIX32 features both
redundant power supplies and redundant network interfaces.
Dante® network audio is a common protocol for distributing high quality linear audio
over standard IP networks and it is widely used by many audio equipment
manufacturers. The Glensound Beatrice Mix32 Dante® audio interface will be
compatible with any other manufacturers Dante audio interface. Further details of
Dante® network audio can be found at www.audinate.com

CONNECTING THE BEATRICE MIX32 TO A DANTE® NETWORK
The Beatrice Mix32 is a network audio device utilising the reliable and versatile
Dante® audio over IP protocol. Dante® is a proprietary system (although very widely
used) the originators of which are Audinate.
The information below is only meant as a very basic guide. Full details of the power
of Dante® network audio and instructions for using it can be found at
www.audinate.com
Getting Dante Controller
If you are connecting the inferno to a new Dante network the first thing you will need
to do is to get the free Dante controller software from Audinate.
This can be downloaded by visiting Audinate’s web site at www.audinate.com
Connecting Beatrice Mix32 To the Network
Beatrice Mix32s can be connected to the network that you are going to use for your
audio distribution simply by plugging in either and or any of the network
connections on the front. Once connected to the network it will be possible to see the
Beatrice from within the Dante controller and route its’ audio circuits.
Audio Over I Network
We strongly recommend that you consider your network topology carefully and
would not recommend sharing broadcast audio and general data on the same
network.
For more details of audio over IP network structure please visit www.audinate.com

Running Dante Controller
At the time of writing this manual the Dante Controller looks as per the screenshot
below:
The Beatrice Mix32 will have been named at the factory during test to allow them to
be identified by the Dante controller.
The format used for the factory name is:
‘Mix32-10aa16-serial-102’
Where ‘Mix32-10aa16’ refers to the Glensound product i.e. Beatrice Mix32 and its
Dante Brooklyn module MAC address and ‘serial-102’ denotes the hardware racks
serial number.
Dante Controller Tip
If you have never run Dante controller before then make sure that on the bottom left
of the Dante controllers’ screen ‘P’ or ‘S’ is next to a green square as this indicates
that it is connected to a network. By clicking ‘P’ or ‘S’ a pop-up box opens to allow
you to set what network interface the controller is using.

age 13 of 27
MIXER MODES
The mixer mode is selected using the rotary Hex switch on the front panel.
IMPORTANT: The position of the rotary switch is only read by the microprocessor
while the Beatrice Mix32 is turning on. So moving the switch to a different position
while the unit is on will make no difference until the unit is powered down and turned
back on.

ASS THROUGH MODE
General
Pass through mode sets each incoming Dante audio circuit to be routed directly to
the equivalent numbered outgoing Dante audio circuit.
Uses
Pass through mode is very useful in network audio systems that incorporate devices
using a 4-channel chipset from Audinate (the company behind Dante®) called Ultimo.
The Ultimo chipset can provide 4 audio inputs & outputs to a Dante® network.
However the chipset can only receive data streams from 2 locations within the
network meaning that to use all 4 incoming audio circuits these must be sent from
no more than 2 different devices on the network.
If you need a device on your network that contains an Ultimo chipset to receive audio
from 4 different network locations then the pass through mode of the Beatrice Mix 32
will have to be used. The principle of operation is very simple. Route all 4 audio
channels originating from different devices that you want to be received by the
Ultimo chipset via 4 pass through channels of the Beatrice Mix 32 and then the
receiving Ultimo chipset will receive all 4 audio channels from just one network
source (and hence work).

CLEAN FEED (Mix-Minus) MODE
 General
In the clean feed configurations several pre-set configurations are available.
Each mix has multiple outputs with each output configured so that it does not
include its own mix input.
For example switch position 2 provides a 32-channel mix. Output channel 5 is a mix
of channels 1-4 and 6-32 so audio from input channel 5 is not present on the
output. This is useful where you wish to contribute to a mix but do not wish to hear
your own voice back.
See the table below for a full list of available clean feed mixes per switch position.
All of the clean feed mixes feature automatic signal ducking. The highest numbered
input channel of a mix has priority and will cause the level of the other channels in
the mix to be reduced.

COM RESSOR/ LIMITERS
Each mixer card has output compressor / limiter circuits built in.
We call the circuits compressor/ limiters because the design of the circuit means that
they are neither a traditional hard limiter or soft compressor. Initially gentle
compression is introduced and as the input signal increases so does the
compression ratio until eventually it becomes a limiter.
All outputs have a compressor/limiter circuit built in.

U DATING FIRMWARE
Equipment needed
 A windows based PC
 USB Type A to Mini B cable
 A copy of ‘DfuSe Demo’ software
 The latest firmware from Glensound
 A STM32 Device and mains power
Instructions
1. Download and install DfuSE Demo
‘DfuSE Demo’ is a firmware updating tool that is required for loading new firm-
ware on to the STM32 Device.
It can be downloaded from the STMicroelectronics website found here:
https://goo.gl/AbzhsA. It is the file named “STSW-STM32080”.
Once you have downloaded this file you will need to extract the .exe
“DfuSe_Demo_V3.0.5_Setup.exe” then run and install it.
2. Download firmware
The latest firmware for the STM32 Device can be found on the Glensound
website under the respective product page. Once you have downloaded the
file place it in a folder or location of your choice.
3. Connect To A PC
Connect the STM32 Device to the PC via the USB cable. The Mini USB
connector is located on a panel of the STM32 Device.

4. Firmware update preperation
To prepare the STM32 Device for a firmware update;
1. Power on the unit
2. Press and hold down the reset button
3. Press and hold down the identify button
4. Release the reset button and then release the identify button a second
after
Your PC should make an audible sound when this process is successful as
windows is detecting a new USB device.
5. Loading the firmware
Now open DfuSe Demo.
If the STM32 Device successfully entered DFU mode then it will appear as
‘STM Device in DFU Mode’ under the ‘Available DFU Devices tab’.
Now the .dfu file needs to be selected so that DfuSe Demo knows the correct
firmware to put on to the STM32 Device.

Click choose and then select the .dfu file that you downloaded from the
Glensound website. This will be located in your downloads folder by default.
If the file loads successfully then it will read along the bottom ‘File correctly
loaded’.
