Media Matrix CAB 8N

The CAB™ 8n is the newest CAB device from MediaMatrix®. It features eight audio channels that can be individually configured as inputs or outputs. This provides unparalleled configuration options for an audio interface. The CAB 8n is a half-width, 1RU-tall device that is capable of utilizing Power over Ethernet (PoE). This compact size allows convenient mounting in equipment racks and under tables, while the unique I/O configuration means all the inputs and outputs required can be handled by a single box. All of this can be connected via a single wire when used with any standard PoE network switch or standard power injector. A 12VDC power inlet is included for situations where PoE is not available. GPIO and serial bridging are also available on the CAB 8n, including eight programmable pins and two Form C relays. The serial bridging is capable of handling RS-232, EIA-422 and EIA-485.
