Links To Dante Compatible Network Or DARK88 Break Out Box
Inferno can be used on its own when connected to a Dante audio network. Many audio routers, consoles and intercom systems are Dante compatible, and will accept the Inferno link, enabling Glensound grade commentary into the audio network.
There are primary and secondary Dante network connections
Inferno can also be used outside of a dedicated Dante network when connected to one of our DARK or AoIP44 break out boxes. This connection can be direct or across a structured network. The DARK or AoIP44 units allow all of the audio inputs and outputs to be located in a place separate from the Inferno.
Programmable On A Dante Audio Network
When connected to a Dante network, sources and destinations can be configured from any part of the network using the free Dante controller software. Details are available at www.audinate.com.
Seven Talkback Circuits
The seven illuminated talkback buttons route the audio input to 7 different destinations and remove the audio from the main programme output.
Eight Input Headphone Mixer
Seven external sources plus sidetone are presented on eight level controls allowing the user to create their own required monitoring mix of all sources. Each input can be independently selected to be on the user's left ear, right ear or both ears. The headphone connection is available on a 3.5mm and a 6.35mm jack socket.
The single input is switchable on the rear panel to be line/mic/48v and has adjustable input gain. The input also features Glensound’s Referee compressor limiter system. This applies a variable rate compressor to the input peaks so that no clipping occurs, without affecting the rest of the audio signal.
The Inferno contains a web server, allowing remote functionality to an engineer from any PC connected to the network via any web browser. Enter the IP address of the Inferno in the browser for remote control of the front end mic gain. It also allows configuration of each push button on the unit to be on/off latching, momentary (push to talk), always on, and off when pushed (cough), or in an intelligent mode where a short press latches or a longer press is just momentary.
15 segment LED PPM Meter
Audio input level is indicated on the 15 segment PPM meter.
Power On Dante Link Or Locally
Inferno can be powered via the network audio connection if it conforms to the PoE standard. There is also an internal 100v-240v mains supply.
Based on industry standards, Dante is an uncompressed, multi-channel digital media networking technology, with near-zero latency and synchronization. Dante is the preferred audio networking solution that has been adopted by more pro-audio AV manufacturers than any other networking technology. Interoperability is not a dream of the future, but a reality today. Hundreds of Dante-enabled products are available from the world’s leading manufacturers, enabling you to mix devices from multiple manufacturers.
Economical and Versatile
One cable does it all. Dante does away with heavy, expensive analogue or multicore cabling, replacing it with low-cost, easily-available CAT5e, CAT6, or fiber optic cable for a simple, lightweight, and economical solution. Dante integrates media and control for your entire system over a single, standard IP network.
Dante systems can easily scale from a simple pairing of a console to a computer, to large capacity networks running thousands of audio channels. Because Dante uses logical routes instead of physical point-to-point connections, the network can be expanded and reconfigured at any time with just a few mouse clicks.
Since audio is transmitted digitally, you don’t have to worry about the common analogue challenges of interference from other electrical equipment, crosstalk between cables, or signal degradation over long cable runs.
Easy To Install
Setting up Dante networks couldn’t be easier. You no longer have to shudder when considering the deployment of an audio network. Even the most complex networks can be set up and configured quickly and easily with Dante, making system integration simple. Dante automatically handles the technical complexities for you.
Signal routing and system configuration with Dante is fast, simple, and incredibly flexible. Dante Controller is a powerful software application that manages devices on the network. Setting up a Dante network is typically just a matter of plugging devices into an Ethernet switch and connecting a computer to the network. All Dante devices are automatically discovered and displayed in Dante Controller, so you can be up and running in seconds.
Easy to Use
With Dante Controller you can easily edit device names and channel labels, control sample rates, and set device latencies. There is no longer any need to remember device IDs or channel numbers. Instead, a single audio channel is referred to just like an email address: “commentatorA @ studio or ”news_mic @ voboothA”. Set it and forget it. Once the network is configured, the computer running Dante Controller can be removed from the network, and reconnected only if changes are required or system monitoring is desired. Signal routing and other system settings are stored safely in the Dante devices themselves, so they are automatically restored if a device is power-cycled.
Network Health and Management
Real-time information about the health of your network is essential for a proper understanding of its performance. There is a rich suite of diagnostic tools within Dante Controller, providing visibility into the network health status through features such as device latency monitoring, active clock health monitoring, packet error reporting, and bandwidth usage statistics.
Many Dante-enabled devices support 'glitch–free' redundancy, enabling a secondary physical network to be provided, duplicating the audio traffic on the primary network. This automatically prevents any audio loss or interruption in the event of a connectivity problem on the primary network.
Unicast or Multicast
Dante audio channels can be configured as unicast or multicast as appropriate, to make best use of available bandwidth. Unicast provides a direct point-to-point stream for unique channels; multicast sends an audio stream to multiple devices simultaneously.
Fully Integrated with Windows and Mac OS X
With Dante Virtual Soundcard, your computer becomes a Dante audio interface for multitrack recording and media playback, using the computer’s existing Ethernet port — no additional hardware is required. Digital Audio Workstations, software-based media players, Skype, iTunes, Pandora, Spotify and other applications are easily integrated into your network via Dante Virtual Soundcard.

There are 2 sets of Firmware (software code) that run in the Inferno.
1) There is an internal microprocessor that handles all the switches, gains and also provides the webpage, this has 1 set of firmware.
2) The Dante Network interface has its own firmware.
There are different updating techniques for each of these 2 sets of code.
1) Updating the microprocessor firmware
Inferno Firmware is currently on version V2.0.4, to check your current Firmware version that is installed please check on the web interface.
The firmware is the code that runs internally in the Inferno and provides the structure for the Microcontroller. The firmware can be updated without the need to return the unit to Glensound.
How To Update The Firmware:
1) Get the new firmware from Glensound’s web site.
A) Copy and paste the below link into your browser to download the file:
Please note the above address is just the address where the file is stored, there is no webpage there, but when you copy and paste the link in your browser it should automatically download.
Make sure you know where your browser has downloaded and saved the file as you’ll need it in a minute. Note Windows sometimes underlines the address above as a link, if you’re typing this in a browser directly then the last part is ‘inferno_v203.dfu’
2) Install on a PC a programme called Dfuse. This is a program that is supplied by ST Microelectronics who are the manufacturer of the intelligent microprocessor that we use in the Inferno. Just Googling Dfuse should provide the link to ST Microelectronics Dfuse download page. Follow the download instructions to download and install Dfuse on your PC.
3) Make sure you know where the latest version of the Inferno’s firmware is located on your pc (this is a .dfu file). This is a file that Glensound will have sent you or you downloaded in step 1.
4) Connect the USB port on the rear of the Inferno that you want to update to a USB port on your PC.
5) Press and hold the ‘IDENTIFY’ button. While pressing the ‘IDENTIFY’ button, press and release the recessed ‘RESET’ button (you’ll need a pencil or pointed object to push the recessed reset button. Do not press too hard, it only moves a small amount).
6) If this is the first time you have connected the Inferno to the PC then windows will load drivers for it.
7) Open the Dfuse software and in the top drop down list select the device shown (there should only be one device available called something like 'STM device in DFU Mode'
8) Under the 'Upgrade or Verify Action' box at the bottom right area of the Dfuse software, use the 'choose' button to locate the downloaded .dfu file.
9) Tick the 'Verify after download' box
10) Use the ‘update’ button (next to the choose button) in the Dfuse software to start the update.
11) Wait for the update to be completed.
11) Press the recessed ‘RESET’ button (or turn the Inferno off / on)…..the new firmware will now be loaded.
2) Updating the Dante Network Interface
The latest version of Dante firmware makes the unit DDM compliant and also AES67 compliant.
It is worth noting that a previous version of code was released to cure an issue with the webserver being swamped by multicast audio data (the symptoms of which are very slow or unresponsive webpages). The Dante network interface needs to be updated on all Infernos shipped before the end of April 2017 (Serial numbers 281 & below).
The firmware that runs the Dante Network Interface is updated using Audinate's Firmware updating tool (Audinate are the company behind Dante). The updating tool and a user guide can be downloaded from Audinate's website https://www.audinate.com/products/firmware-update-manager.
The actual firmware to install using the above tool can be downloaded from: http://www.glensound.co.uk/Software/Dante/INFERNO_v1.0.2_Dante_v18.104.22.168.dnt
When you download the above file please make sure that you know where your computer has saved it before installing it with Audinate's update tool.
Please note we strongly advise that when you do the update that only your PC and the Inferno that you wish to update are on the network to save accidently updating the wrong Dante device.
