DESCRIPTION
The CAB 4n is an audio breakout box designed to enhance the versatility of MediaMatrix NION audio systems. It is fitted with
four module bays that support a variety of optional I/O modules. The unit will can be loaded with one, two, three or four
modules to provide any combination of microphone, line and output connections, including 16x0, 0x16, 12x4, 4x12 and 8x8.
Input channels can be managed in groups of four.
The CAB 4n features a versatile GPIO port, which provides analog, digital and dry contacts. All of the GPIO ports are
configurable using the NWare™ software. A DIN rail mounting system, called the GPIO-25, is also available to give efficient
rack wiring and service.
There are three variations of the unit, each fitted with a different audio networking module:
CAB 4n CM-1 is a CobraNet model that features 8 and 9-bit serial bridging. This is required for legacy ControlMatrix projects.•
CAB 4n CM-2 is a CobraNet model that offers optional advanced CobraNet subchannel mapping.•
CAB 4n Dante interfaces with the Dante audio networking protocol through the use of Audinate's Dante Legacy Module •
(DLM).
