Network I/O Forward Thinking Audio Routing for Broadcast Production
Forward Thinking Audio Routing for Broadcast Production
SSL Network I/O is a range of devices which facilitate use of IP Audio networking using Audinate's Dante technology for broadcast audio production. Dante is an IP Audio Network which uses standard IT infrastructure for audio transport, routing, device discovery and control. The release of SSL's Network I/O range adds the substantial weight of the SSL brand to the adoption of Dante as the industry choice for IP Audio networks. With Dante committed to conform with AVB standards and with AES67, the SSL Network I/O range is ready for future networked audio developments. IP audio networking offers a fresh approach to audio routing and asset sharing for broadcast production with a wide range of benefits:
- High Channel Counts: 512ch @ 48kHz (256 @ 96kHz) on a single 1GB connection
- Guaranteed Interoperability: plug & play discoverability of 500 devices from 220 different manufacturers - and growing
- Remote Device Control: parameters configured anywhere on the network
- Reduced Cost: standard low cost IT hardware, standard and/or existing Cat 5 or Cat 6 cabling with audio and control on the same network down a single cable
- Simplifed Interconnectivity: Ethernet/IP connectivity simplifies interfacing with a wide range of devices including Intercoms and Station Automation
- Flexible Scalability: systems can grow as your needs evolve. Want a bigger network? Add another switch!
- Full Network Redundancy: technology tried and tested across many industries and fully compatible with all network redundancy models
- Distributed Routing Control: routing control from unlimited devices or terminals
- Absolute Resilience: catastrophic failure of a single device will have no effect on any other devices in the network
- Standards compliant: IEEE and IETF compliant thus deployable on and can mix with trac on any standard IP infrastructure. SSL Network I/O is AES67 compliant.
There are currently four products available in the SSL Network I/O range:
Standalone Broadcast Specification MADI to IP Audio Network Interface
The SSL Network I/O: MADI-Bridge is a broadcast specification bridge between the industry standard MADI audio format and IP audio network's using Dante. The MADI-Bridge enables C100 and C10 Digital Broadcast Consoles or any other standard MADI device to connect to Dante based IP Audio networks with full redundancy maintained.
With 64 channels per Bridge (@ 48kHz) and up to 512 channels per 1GB network link, Dante is fully scalable and capable of providing routing channel counts from tens to thousands and beyond using standard IT infrastructure. Redundant PSU, MADI ports and IP Network ports mean the Bridge is built for uninterrupted operation, keeping critical devices and audio paths functioning throughout the broadcast facility. In addition to the inbuilt clock redundancy options in Dante controller, the MADI-Bridge also includes a pair of redundant sync inputs for use as a self-redundant Dante Grand master clock. 32bit MADI control tunnelling allows a pair of MADI-Bridges to be used to pass audio and user bits of a whole MADI stream across a network. Remote locating existing MADI Mics or increasing cost efficiency of an existing fibre cable beyond a single MADI stream is now a simple task. The Bridge also features Bidirectional sample rate conversion between any asynchronous sample rates, from 44.1kHz to 192kHz. Intended for use with Dante controller and third party Dante products, the MADI-Bridge shows commitment to interoperability while understanding Broadcasters critical needs.
The SSL MADI-Bridge features a front panel headphone socket (with rotary level control) and inbuilt headphone monitor routing, to truly replace traditional patch bay confidence routing and fault finding functionality with equivalents in the IP Audio domain. Simple font panel controls facilitate routing mono or stereo paths from MADI In, MADI Out, Dante In or Dante Out directly to the headphones. A front panel LCD screen provides signal present metering selectable to show four points in the signal chain: MADI In, MADI Out, Dante In and Dante Out. GPIO connections allow for transfer of tally info and switching functions across the network with the Audio.

Remote Control Application Details
The Network View in upper section of the GUI shows each SSL Stagebox on the Dante network with large arrows to scroll through all SSL Stageboxes currently available on the network. A flashing red border indicates a specific device with a clipping audio channel, a solid red border highlights a device with an active Attention flag. Each device has redundant PSU status LED’s and is shown with the appropriate number of channels. Each channel has with individual level displays and Attention, Lock and Mute tallies. Devices that have been connected to the network while the application is running but have subsequently lost communication show as "Offline". Clicking a device brings its parameters into the Detail View.
Shows and provides control over the parameters for a selected device. Individual channels have an Info overview box, a lock button which prevents accidental changes, level display, gain displays (which can be used for numeric editing), a fader (which is unavailable if the channel is locked) and a mute button. The GPIO controls are available to the left of the Detail View.
Shows an expanded detail view for a selected channel with a full set of controls: +48V phantom power, Mic/Line select, Attention (which toggles the red status LED for the channel on the hardware unit), Gain, Lock and ‘Show Gain’ which toggles the fader into the Focus Window. The function of the Pad button is dependent upon the Pad Mode selected via the Setup page. In traditional Pad mode the button engages a classic -20dB pad. In SSL AutoPad Mode the button shows a change in status when the pad is automatically engaged but does not switch the pad.
AutoPad is an innovative system that automatically applies a Pad according to gain setting. The pad is automatically included in the fader gain range and applied if the gain is set at a low value that would require a pad to achieve. This allows the entire possible mic gain range to be seamlessly available at all times.
A set of Navigation controls in the lower right corner of the GUI provide channel navigation and level controls that are mapped to your PC keyboard to provide immediate hardware control. ◂ ▸ Left and right arrows call the previous or next channel on the device to the Focus Window. At the first or last channel of each device navigation will transfer to the adjacent channel of the next device shown in the Network View. ▴ ▾ Up and down arrows alter the gain by 1 dB. Alt toggles the gain step to 3 dB. Control toggles the gain step to 0.1 dB. These keys and combinations are mapped to your PC keyboard. For example, pressing ALT+UP on your keyboard will increase the gain by 3 dB.
The Setup Page shows an addition set of information and controls for each device. PSU and Fan status is shown alongside temperature readings taken at three locations within the Stagebox. Global operating level for the Stagebox can be set at a range of settings between 15dBu and 24dBu. The AutoPad button toggles the Pad Mode between traditional -20dB Pad and SSL AutoPad.
