INTRODUCTION AudiaEXPI-4 is an input expander that accepts four mic/line analog audio inputs and provides four channels of digital audio output via CobraNet®. AudiaEXPO-4 is an output expander that accepts four channels of digital audio input via CobraNet and provides four mic/line-level analog audio outputs. [. . . ] 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.

AudiaEXPI/O-2 - Front Panel
Peak Indicators (Inputs 12): These red LEDs will light whenever input channel signal levels exceed 6dB below clipping. Use this feature to aid in the adjustment of the Trim controls (see below). Rotary Encoder & LCD Display: This control and display are used for initial setup of the AudiaEXPI/O-2 unit. When power is first applied to the unit, the display will cycle through a product description, followed by a title screen. Rotate the control to make a selection, then press the control again to edit that selection. Additional levels of selection may be available using this same routine. Some edits will require a choice of OK or CANCEL. Some selections are only informational and cannot be edited. Select BACK to return to a previous level, and select to advance. Primary selections are as follows: BUNDLE NUMBER (CobraNet bundle number to logic input assignments); COBRANET LATENCY; INPUT GAIN (0 +66db in 6db steps); OUTPUT GAIN (0, -6, -12, -18, -24, 55 db); PASSWORD PROTECT (prohibits unauthorized tampering); TITLE DISPLAY (personalized: 2 lines with 8 characters each); ABOUT (Serial#, FW Version, Boot Ver, Board Revisio, CobraNet FW, Mac Address and Up Time). Mic/Line Outputs: These two mic/line-level analog audio outputs are provided on balanced plug-in barrier-strip connectors. For unbalanced output, wire high to (+) and ground to (), leaving (-) un-connected. Mic/Line Inputs: These two mic/line analog audio inputs are provided on balanced plug-in barrier-strip connectors. For unbalanced input, wire high to (+) and ground to both (-) & (). For use with condenser microphones, +48 volt phantom power is available at these inputs (see Rotary Encoder above). Power + Data: This RJ45 connector provides the CobraNet digital audio interface. CobraNet allows multiple CobraNet-equipped devices to share digital audio on a system network. A 10/100Base-T Ethernet switch (not hub) is required when networking multiple units. The maximum distance between any unit and an Ethernet switch is 100 meters. Additional Ethernet switches, or even fiber-optics, can be used to further extend distances between units on a system network. Signals from the central control room are distributed to all concourses via fiber-optic transmission of CobraNet® and Ethernet. The central control room has two Networked Paging Station-1 units for all-call paging, three digital message repeaters for announcements, a single background music source, one AudiaEXPI-4 Input Expander unit, and one Audia EXPI/O-2 Input/Output Expander unit. [. . . ] Mixing and processing of these signals (to achieve proper microphone/track assignment and consistent recording levels) has been accomplished back at the AudiaFLEX units.
