Gibraltar Network Cage - Rack Card Housing

Gibraltar Network Cage

The Gibraltar Network Cage is the basic building block of the Wheatstone Gibraltar Network (TDM). These compact powerhouses can be configured with various DSP, I/O, CPU, and power supply elements to build any sized network, from one control room to dozens.

The Gibraltar Network Cage makes audio networking PRACTICAL. It's simple to install, easy to learn, and certain to reduce system costs. Compact enough for small applications, yet stackable for tremendous growth potential, it's design consists of a seven-inch, rackmount frame capable of handling 512 simultaneous audio channels on its backplane.

The Gibraltar Network Cage can be configured with a variety of plug-in cards for system access and virtually any audio source format and interface path: analog, digital AES (with sample rate converters), MADI, SDI de-embedding, and control surface mix engine cards. There’s even an audio-to-Ethernet interface that provides single wire integration to station audio automation playback systems.

Using the 4864 core switch, you can connect up to 48 I/O mix engine frames, each capable of 512 audio I/O paths. Because the mix engine is integral to the router, any input is available to any mix, and any input or mix is available to any output system-wide, forming a true router-based network system.

The cage’s audio cards are front loading, so service can be performed in real-time. Cards are available to provide virtually any type of mechanical interface suited to your application. Interface modules simply plug in from behind to provide RJ, DB, BNC or screw terminal connections.

Cages can be stacked to suit particular card complements (analog or digital input and output cards or optical network cards) but more significantly, cages can be separated by great distances and network audio through either bi-directional fiberoptic links or a single CAT6 wire.
