The CAB 4n continues in the tradition of high-end audio networking set forth by the time-tested CAB Series. The CAB 4n break-out box was designed specifically for NION based systems. The CAB 4n features MediaMatrix Scalable I/O Architecture, with support for the popular line of MediaMatrix I/O modules (up to four modules configurable for 16×0, 0x16, 12×4, 4×12 or 8×8 operation, IxO). All inputs can be configured in groups of four channels for microphone or line level in any of the available configurations. The CAB 4n features a versatile, performance-oriented GPIO port, which provides configurable contacts for analog, digital and dry contact use. All of the GPIO ports are configurable from the NWare software and include an easy DIN rail mounting system for efficient rack wiring and service.
