DESCRIPTION
The CAB 8n Configurable Audio Bridge is a professional digital audio processor intended for fixed installation applications. It
provides eight audio channels and a GPIO interface in a compact enclosure. The device is designed for use with MediaMatrix
NION networked DSP systems in professional and commercial audio and communications applications. The cost-effective,
1U-high, 1/2U-wide unit can be powered directly from the Ethernet network using Power-over-Ethernet, or from a DC
power supply. Each of the eight audio channels can function either as an analog audio input to the CobraNet audio network,
or as an analog audio output from the CobraNet audio network. Audio inputs accept microphone or line-level audio signals,
with phantom power, and allow fine-grained remote control of input gain. Audio outputs provide line-level audio signals with
fine-grained remote level control, relay mute, and direct monitoring of the analog output signal.
The CAB 8n features a wide range of control interfaces to third-party systems, including eight channels of configurable GPIO,
each of which may be independently configured as logic input, logic output, high-current voltage output or analog control
voltage input. The unit also features two dual-pole user-controllable contact-closure circuits, a fault indicator contact-closure
circuit, and a user-controllable RS-232, EIA-485 and EIA-422 full-duplex serial port.
