[. . . ] AudiaEXPI/O-2 is an input/output expander that accepts two mic/line analog audio inputs, provides two channels of digital audio output via CobraNet, accepts two channels of digital audio input via CobraNet, and provides two mic/line-level analog audio outputs. All three expanders are in a convenient half-rack-width format. They can simply add inputs and outputs to a centralized Audia system or extend system boundaries by providing inputs and outputs in remote locations. AudiaEXPI-4, AudiaEXPO-4, and AudiaEXPI/O-2 are represented as explicit CobraNet Input or Output blocks in Audia software for easy inclusion into any system design. [. . . ] Typically, "unicast" bundle numbers (256­65, 279) are used to exchange digital audio between two specific devices. With unicast bundles, each CobraNet device can transmit to as many as 16 other devices within a network (2 bundles per channel x 16 bundles max = 32 channels). With "multicast" bundle numbers (1­255), digital audio can be exchanged with multiple devices. Due to network delay, CobraNet has a limitation of seven (7) "hops" (one-way transmissions) within a network. In order to integrate AudiaEXPO-4 into an Audia system, a CobraNet output block must first be placed into the design layout. Audia units intended to transmit digital audio to the AudiaEXPO-4 must have their CobraNet jacks connected to the same network. Both the AudiaEXPO-4 unit (hardware) and the CobraNet output block (software) must be assigned matching bundle numbers, before digital audio can be successfully exchanged. CobraNet Latency settings must be identical in all devices, system-wide. Also, unicast and multicast bundle numbers can be used to access digital audio from individual or multiple CobraNet output blocks. Similar considerations may apply when using AudiaEXPO-4 with other CobraNet compliant systems or devices. AudiaEXPI-4, AudiaEXPO-4, and AudiaEXPI/O-2 can exchange digital audio directly (outside of a system network) using either a simple "cross-over" CAT5 cable or an Ethernet switch. 5 AudiaEXPI/O-2 - Front Panel Peak Indicators (Inputs 1­2): These red LEDs will light whenever input channel signal levels exceed 6dB below clipping. Bundle numbers are used to determine where digital audio is transmitted and received.

[. . . ] Additional Ethernet switches, or even fiber-optics, can further extend distances between units on the network. Each AudiaEXPO-4 receives four channels of digital audio via CobraNet over a single CAT-5 cable. These four channels of digital audio are then converted to analog audio and appear on four separate output connections. Each AudiaEXPO-4 provides the appropriate channels of audio for one of the four court recording systems. [. . . ]
