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. [. . . ] 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. 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. 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. Outputs are provided in the central control room for distributed speaker systems (ticket counters, baggage claim, etc. ). Each of the airport's six concourses includes eight boarding gates. [. . . ] 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. Mixing and processing of these signals (to achieve proper microphone/track assignment and consistent recording levels) has been accomplished back at the AudiaFLEX units. 9 APPLICATIONS 10 SPECIFICATIONS 11 BLOCK DIAGRAMS 12 WARRANTY BIAMP SYSTEMS IS PLEASED TO EXTEND THE FOLLOWING 5-YEAR LIMITED WARRANTY TO THE ORIGINAL PURCHASER OF THE PROFESSIONAL SOUND EQUIPMENT DESCRIBED IN THIS MANUAL 1.
