cab 4n Configurable Audio Bridge Data Sheet 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). Features • Scalable I/O architecture • Buddy Link redundancy system (CobraNet models only) • Supports all MediaMatrix 4-channel I/O modules • GPIO port with 8 configurable GPIO pins • Supports one, two, three, or four modules in any combination of mic in, line in, and output. • 4 "Form C" relays with NO and NC connections, contacts rated for 1A • Supports both CobraNet and Dante audio network modules • GPIO-25 DIN rail breakout panel for external control terminations (available separately) • Front panel level meter for each channel • Front panel network status and fault indicators • 48 kHz sample-rate • 24-bit quantization, 64x oversampling • Integrated CobraNet serial bridging for EIA-485 (CobraNet models only) • Universal power supply (100-240V 47-63Hz) with removable IEC power cable.

With Dante, base address is shown at power up; afterwards, audio input/output levels are shown. Hardware base address switches: 4-position rotary switches for setting hardware base address (ID). Located behind removable cover on the front of unit. Fault LED: Indicates hardware fault or unexpected condition from the audio networking module. Conduct LED: Indicates the CAB 4n is an active Conductor on the CobraNet network. Link LED: Indicates that a physical layer connection has been established. RX and TX LEDs: Indicate data reception and transmission via the audio networking module. Power LED: Indicates that the CAB 4n is receiving power.

Buddy Link In & Out connector: BNC connectors to transmit link data to another CAB 4n as part of Buddy Link process (CobraNet models only). Audio networking module bay: Supports audio networking modules with the Cirrus Logic CM-1 footprint. Currently supported modules are the Cirrus Logic CM-1, Cirrus Logic CM-2 and Audinate Dante Legacy Module (DLM). A network connection via one of these modules to a supporting device is required to pass audio. GPIO port: Female DB-25 connector with 8 configurable, general purpose ports (supporting digital I/O, analog I/O or rotary encoder), plus 4 relays. EIA-485 ports: Two two-wire, half duplex EIA‑485 removable Euro connectors. Each is internally wired to support busing of communicating hardware via a serial connection. Audio connectors: Support for balanced, three‑wire connections on removable Euro connectors. These are available on audio input and output cards. The cards are color-coded: MM-Line4 (four channel line input) - black, MM-Mic4 (four channel mic input) - green, MM-Out4 (four channel line output) - blue.
