Combining groundbreaking performance with the ultimate in flexibility, Freeway offers the widest range of solutions for small to medium scale routing requirements. The combination of two frame options, a highly modular switching card architecture and an extensive integrated control system enables Freeway to be tailored for applications in the broadcast, transmission, post production and outside broadcast environments. The Freeway family is based around two frame sizes, a switching modularity of 16 channels and is available in three series, dependant upon the maximum size that the system is planned to grow to.
Freeway 128
Freeway 128 is available for stereo analog audio and AES/EBU digital audio permitting systems up to 128x128 to be assembled, using 8 modules in the 6U frame. Freeway 128 Timecode and RS422 variants permit system up to 128x128 and 128 ports, respectively, to be assembled within the 3U frame using 4 modules each providing 32 channels. For analogue video, a range of 16 channel splitters and combiners is available, allowing four 64x64 levels to be interconnected to provide a 128x128 router.
AES Digital Audio
When operated as a reframing routing system for synchronous signals between 32kHz and 54kHz, Freeway’s digital audio router ensures that all switching occurs at sample boundaries, removing clicks and disturbances caused by bitstream corruption. In transparent mode, signals between 24kHz and 96kHz may be supported. For flexible integration, routers may be configured with either balanced I/O using 50 way D connectors, or unbalanced I/O using BNCs.
Operation in a mixed balanced environment is possible in groups of 16 inputs and outputs by employing different rear connector assemblies.
Stereo Analogue Audio
The analogue audio Freeway offers the benefits of a hybrid digital core, together with many facilities to enhance the routing operation. To compensate for external signal errors, any stereo analogue signal may be left/right swapped or routed as left to both or right to both. In addition, a mono derivative of any analogue source may be produced and sent to an analogue destination. Transformerless I/O circuits, providing level adjustment up to +24 dBu, combined with outputs that are indefinitely protected against short circuits ensure easy installation in any environment.
