Solid State Logic - Challenge... Solution... Result
Taking Solid State Logic's Product Demonstration Area to the Next Level
SOLUTION
When the time came to plan the new installation, SSL engineers sat round the table with Adder to work out a flexible,
cost efficient solution to the various challenges. A key technical obstacle was how to deal with Mac and PC display,
keyboard and controller technology, particularly the need for hi-resolution video and USB 2.0 serial connections. The
solution came in the form of Adder's new AdderLink X50 module. This combined the required video resolutions, with
USB 2.0 capability and common Cat5e based wiring. At the machine end, each Mac and PC is connected to it's own X50
transmitter. Cat5e is then wired to a manual Cat5e Patch and in each studio, the displays, keyboards, mice and USB ports
are taken from the X50 receivers. To provide additional video only feeds to HD projectors and secondary TFT displays,
the installation uses parallel AdderLink AV100 units, again via a Cat5e patch.
The central machine area is on the ground floor, meaning that the longest cable runs to first floor studios are approxi-
mately 40 metres (130 ft.), initial testing proved that the X50 would be capable of all the video resolutions needed, even
at the longest distances. Also the USB performance gave snappy pointer and keyboard reactions. Projector video feeds
also had great resolution performance, all the video and control problems were solved.
RESULT
Audio at the Speed of Light
With a solution to the challenges of workstation control and display, the next hurdle was how to deliver the same flex-
ibility for SSL's audio. Key to solving this challenge were SSL's MORSE fibre MADI router and Alpha-Link Fibre MADI
Convertors. Each room was wired for several fibre MADI feeds all connected to the MADI router in the machine area.
All consoles, processors and workstations were also connected to the fibre router, creating the world's largest MORSE
routing system and eliminating approximately 10km of multi-core and co-axial wire in the process.
Multiple Synchronization
As if this project weren't complex enough, another challenge is system synchronization. In most installations, there's a
single source of Video sync and Wordclock and that is distributed throughout the whole facility. A complex demand on
SSL's resource is the need to work in different studios using different standards, for example, PAL and NTSC, Tri-Level
sync for HD and also often at different digital audio sample frequencies. To resolve this challenge the facility has multiple
master sync sources that are used to create all the house sync signals. Each studio can then be patch isolated to allow
any console and associated workstation to work independently of another. In normal operation, the whole facility is
locked to a master clock source to ensure complete synchronicity.
In Summary
From HD video production to film dubbing, from evaluating the latest processing plug-in to training the basics
of mixing console operation, SSL's PDA is now equipped for a huge variety of production tasks for today and into the
future. Along the way, facility power consumption has reduced enough to eliminate the need for two significant AC
systems and more space liberated for future expansion. The combination of Cat5e, Fibre MADI, Adder KVM technology
and SSL MORSE routing have brought a new era to the development of SSL's products and services.
