The SSL SB 8.8 Dante Analogue Stagebox is an eight-channel, mic/line SuperAnalogue stagebox with remote-control software for all high-quality AoIP applications
As Dante emerges as the audio over IP (AoIP) high-speed, low-latency network protocol of choice for numerous professional audio systems, SSL introduces the SB 8.8 Dante Analogue Stagebox (that’s “analog” to our friends across the pond), offering SSL’s signature technology and sound for Dante IP Audio Networks. For “show must go on” reliability, the SB 8.8 provides a redundant pair of RJ45 Dante network connectors, redundant network extension connections, redundant PSUs (brought to you by the department of redundancy department), and GPIO (general purpose input/output) connectivity.
The SSL SB 8.8 has individual front-panel “signal present,” “phantom power,” and “local attention” LEDs to provide quick and familiar visual feedback. And whatever your application, SSL Network I/O devices dramatically improve your sound quality and workflow.
SSL SB8.8- Dante Analogue Stagebox—Just the Facts:
- Eight Superanalogue mic/line inputs
- Interface between studio/stage/recording-area and IP audio networks via Dante
- Redundant PSUs and Dante ports
- GPIO connectivity–embed tallies across the network
- Redundant network extension ports
- Clear front-panel indication–signal present, phantom power, channel attention
- Front-facing XLR connections
- AutoPad automatically adjusts gain and pad settings to accommodate widest possible range of input signals
- Three-speed, ball-bearing fan cooling is sufficiently quiet to place on a studio floor
SSL Network I/O : SB 8.8—Under the Hood
The eight-channel SB 8.8 features built-in limiters and SSL’s innovative AutoPad system, which automatically applies a pad (according to gain setting), making the entire possible mic gain range seamlessly available at all times. Plus, an Audition feature allows individual channels to be monitored over the network (using an SSL console or App) without the signal actually being routed to a network destination.
SSL Network I/O Stageboxes
The SB 8.8 Dante Analogue Stagebox is one of SSL’s Network I/O range, which makes the superior audio performance of SSL's renowned SuperAnalogue preamp design available to a wide range of Dante network applications. Designed for use on any Broadcast studio floor, venue, or live recording room, SSL Network I/O Stageboxes allow easy deployment of Mic Pres and Speaker feeds where needed. SSL Network I/O’s plug-and-play features allow devices to easily be moved between locations while retaining routing and settings if required. All units can be remote-controlled via System T broadcast consoles and control interfaces, SSL Live consoles, and the SSL Remote Stagebox Application.
Dante Audio over IP
Dante IP Audio networking provides an extremely versatile solution for multi-user environments where digital audio assets are shared across multiple recording areas and control rooms. With more than 350 Dante-enabled products by more than 150 different manufacturers already released, Dante by Audinate is A/V’s leading high-speed, low-latency network audio protocol. Able to use standard IT infrastructure (Ethernet cables, connections, network routers, and switches) Dante provides a cost-effective solution for audio distribution, routing, device discovery, and control. The ability to use IP audio networking offers a fresh approach to audio routing and asset sharing for audio productions offering a wide range of benefits.
Dante features and benefits:
- Up to 512 channels @ 48kHz (256 @ 96kHz) on a single 1GB connection
- Plug-and-play automatic discoverability of more than 500 devices from 220 different manufacturers—and growing
- Remote Device Control lets you configure parameters anywhere on the network
- Uses 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
- Ethernet/IP connectivity simplifies interfacing with a wide range of devices including Intercoms
- Scalable systems can grow as your needs evolve. Want a bigger network? Just add another switch
- Full network redundancy: technology tried and tested across many industries and fully compatible with all network redundancy models
- Distributed routing control from unlimited devices or terminals
- Analog-style workaround means that catastrophic failure of a single device will have no effect on any other devices in the network
- IEEE and IETF compliant can mix with traffic on any standard IP infrastructure
- With Dante committed to conform with AVB standards and with AES67, the SSL Network I/O range is ready for future networked audio developments
SSL Stagebox Remote Control Application
The SSL Stagebox Remote Control application provides comprehensive control of SSL Network I/O Stageboxes in a Dante network. Stagebox Remote Control software can be installed on any PC in any location in the network. Multiple instances of the software can coexist on the network, each with access to any of the SSL Stagebox units available on the network. The Remote Control Application offers complete control over the extensive feature set of SSL’s Stageboxes and acts as a communication aid with clear real-time device and channel attention indication.
Stagebox Remote Control key features:
- Comprehensive control of SSL Stageboxes via Dante network
- Clear real-time device and channel-attention indication
- Runs on any PC anywhere on the network
- Multiple instances can coexist and control all Stageboxes on the network
The Network View in the GUI shows each SSL Stagebox on the Dante network with large arrows that enable you to select from the range of SSL Stageboxes currently available on the network. Other visual feedback includes a flashing red border, which indicates a specific device with a clipping audio channel, and a solid red border that 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 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.
The Detail View displays and provides control over the parameters for a selected device. Individual channels have an Info overview box, a lock button that 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 (general purpose I/O) controls are available to the left of the Detail View.
The Focus Window shows an expanded view for a selected channel with a full set of controls, including +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 in the Setup page. In traditional Pad mode, the button engages a standard -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 another SSL innovation that automatically applies a Pad according to the current 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. These controls 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 and will continuously transfer from them to the adjacent channel of the next device shown in the Network View. Up and down arrows alter the gain by 1dB. “Alt” toggles the gain step to 3dB. For fine adjustments, “Control” toggles the gain step to 0.1dB. These keys and combinations are mapped to your PC keyboard. For example, pressing ALT+UP on your keyboard will increase the gain by 3dB.
The Setup Page shows an additional 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 AutoPad.
