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/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 analo 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. All three expanders may also be used to provide additional inputs and outputs to other CobraNet-compliant systems or devices and are Power-over Ethernet (PoE) capable.

AudiaEXPI-4 - Front Panel

Peak Indicators (Inputs 1–4): 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-4 unit. When power is first applied

to the unit, the display will cycle through a product description, followed by a title screen. Press the control to enter setup. 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 LATENCY; INPUT GAIN (0 – +66dB steps); PHANTOM POWER (assigns phantom power to inputs); 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 Inputs: These four 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 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. A CobraNet-enabled device can support up to 64 channels (depending on manufacturer implementation) of digital audio over Fast Ethernet using CAT-5 cable. CobraNet transmits digital audio on “bundles” of up to (8) channels each. The same is true for receiving digital audio over CobraNet. Bundle numbers are used to determine where digital audio is transmitted and received. Typically, “unicast” bundle numbers (256–65,279) 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 (1–255), 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 AudiaEXPI-4 into an Audia system, a CobraNet input block must first be placed into the design layout. AUDIA units intended to receive digital audio from the AudiaEXPI-4 must have their CobraNet jacks connected to the same network. Both the AudiaEXPI-4 unit (hardware) and the CobraNet input 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 route digital audio to individual or multiple CobraNet input blocks. Similar considerations may also apply when using AudiaEXPI-4 with other CobraNet compliant systems or devices. AudiaEXPI-4, AudiaEXPO-4, and Audia EXPI/O-2 can exchange digital audio directly (outside of a system network) using either a simple “cross-over” CAT-5 cable or an Ethernet switch.

Mic/Line Outputs: These four 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.
