Designed for a flexible future A Freeway frame can accommodate a total of four signal cards; each providing a 16x16 switching module. These modules may be interconnected within the frame (using the internal expansion bus) to produce router sizes of 16x16, 32x32, 48x48 and 64x64.
Upgradable in the Field Freeway's modularity ensures that the router can change to accommodate evolving requirements. Switcher sizes below 64x64 may be "plug and play" upgraded in the field. Similarly a predominantly analog router can gradually be "transformed" into a digital router (by swapping analog sixteen square modules for digital alternatives) as installation requirements change.
Comprehensive, Complete Control
Internal database editing functions provide extensive system configuration options including; programmable salvos, source and destination associations, marrying, route protects and inhibits, audio channel configurations and overrides. Up to 8 levels of Freeway routing may be slaved to the main frame by means of a parallel control link. A special version of this parallel link is also available to slave pre-existing TM series routers.
Pro-Bel Performance and Reliability By utilizing advanced PSU circuit topology and the latest signal switching technologies, Freeway offers a very compact router with low power dissipation, ensuring "fit and forget" reliability. For extra security, each frame has provision for two PSU modules so that one may act as a backup in the event of a PSU fail.
The high-speed converter technology in the PSU is monitored by two on-board microprocessors which assess the condition of the mains and of the supplies leaving the power unit. Should any of the PSUs "vital-signs" show a warning condition, these are monitored, and if appropriate, an external warning alarm may be activated. Freeway PSUs may be withdrawn from the unit from the front and a replacement "hot-plugged," thus ensuring continuous service.
Freeway - Take the Open Road Choosing a switcher is an important decision, no one wants to get it wrong. With the current revolution in television production, the need is for systems that can accommodate change. The solution is Freeway, the only future-proof, modular multi-format routing system that provides the smoothest, most affordable path to the future.
Serial Digital Video
Analog Video Any demanding analog television application will benefit from the inherent wide bandwidth and high slew-rate characteristics of this router. The circuitry offers complete transparency to all vertical interval encoded data and is fully compatible with sound in sync signals.
Audio Routing
Freeway therefore, offers the possibility of format-independent signal routing with inherent conversion between AES and analog signals. For instance, a 32x32 stereo analog audio router and 32x32 digital audio router can be housed in the same 3RU frame and permit the routing of any analog source to a digital destination and vice-versa. This flexibility demonstrates Pro-Bel's design commitment to the future.
Analog Audio Routing Freeway provides up to 64x64 stereo routing in a 3RU frame and many associated features which aid a mixed mono/stereo environment, including; left/right to both, mono-mix and channel swap. Transformerless I/O circuits are level adjustable (up to a maximum of +24dBu) and outputs are indefinitely protected against short circuits.
AES Digital Audio When operated as a reframing router, the Freeway AES router provides silent, "click-less" switching between digital audio signals at 32 to 54kHz rates. Operation at rates between 24 and 96kHz is supported by configuring the router in a transparent mode. To promote flexible integration within any digital audio environment, routers may be configured balanced or unbalanced (75 ohms).
