When power is first applied tothe unit, the display will cycle through a product description, followed by a title screen. Press the control to enter setup. Rotate the controlto make a selection, then press the control again to edit that selection. Additional levels of selection may be available using this sameroutine. 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: COBRANET PARAMTRS (CobraNetbundle, latency, & sample rate settings); AES3 PARAMTRS (various digital audio settings); LOGIC PRESETS (store/recall logic inputpresets); PASSWORD PROTECT (prevent tampering); TITLE DISPLAY (create custom title); HARDWARE STATUS (display operationalinformation); ABOUT (display serial# and version information).

Output pairs 1-2 & 3-4 are also available as SPDIF outputs, and output pairs 5-6 & 7-8 are also available as TOSLINK outputs.SPDIF outputs are provided on RCA jacks and should be wired using 75 ohm coaxial cable, with Tip (+) and Sleeve (ground). TOSLINKoutputs utilize optical digital audio patch cables.Word Clock Out: This BNC connector provides clock output from CobraNet.Logic Inputs: These eight Logic Inputs allow remote control of preset configurations. Preset configurations may be assigned to LogicInputs 1~8 using the front panel Rotary Encoder (see above), and can then be selected via external contact-closures (wired from thecorresponding logic inputs to ground).CobraNet: These two RJ45 connectors provide the CobraNet digital audio interface. CobraNet allows multiple AUDIA units to sharedigital audio (and DSP resources) on a system network. This also allows AUDIA units to be used with CobraNet compliant devices fromother manufacturers. A 10/100Base-T Ethernet switch (not hub) is required when networking multiple units. The maximum distancebetween any unit and an Ethernet switch is 100 meters. Additional Ethernet switches, or even fiber-optics, can be used to further extenddistances between units on a system network. The primary and secondary CobraNet ports are redundant. CobraNet supports 64channels of digital audio (32-in & 32-out) over Fast Ethernet, using CAT-5 cable. CobraNet transmits (32) channels of digital audio on (4)'bundles' of (8) channels each. The same is true for receiving digital audio over CobraNet. Bundle numbers are used to determine wheredigital audio is transmitted and received. Typically, 'unicast' bundle numbers (256~61,439) are used to exchange digital audio between twospecific devices. With 'unicast' bundles, each CobraNet device can transmit to no more than (4) other devices within a network. With'multicast' bundle numbers (1~255), digital audio can be exchanged with multiple devices. Due to network delay, CobraNet has a limitationof seven (7) 'hops' (one-way transmissions) within a network.In order to integrate AudiaEXPO-D into a AUDIA system, an EXPO-D (or CobraNet) output block must first be placed into the designlayout. AUDIA units intended to transmit digital audio to the AudiaEXPO-D must have their CobraNet jacks connected to the samenetwork. Both the AudiaEXPO-D unit (hardware) and the EXPO-D output block (software) must be assigned matching bundle numbers,before digital audio can be successfully exchanged. AudiaEXPO-D bundle number assignment can be changed in real-time to allowaccess to digital audio from different EXPO-D output blocks within the system. 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 EXPO-D outputblocks. Similar considerations may apply when using AudiaEXPO-D with other CobraNet compliant systems or devices. AudiaEXPI-D andAudiaEXPO-D can exchange digital audio directly (outside of a system network) using either a simple 'cross-over' CAT5 cable or anEthernet switch.3

APPLICATIONThis application demonstrates the use of AUDIA ® in a house of worship. This is a networked system using one AudiaFLEX 8-Output CMunit, an AudiaEXPI-D 8-Input Digital Expander unit, and an AudiaEXPO-D 8-Output Digital Expander unit (eight digital inputs, eight digitaloutputs, eight analog outputs, CobraNet). An example system diagram is shown on the opposite page, and a representative design layoutis shown at the bottom of this page.Multiple microphones, for speech and music performance, are connected to inputs of a digital mixing console located at the Front-of-Housemixing position. The console provides multiple mixes, including effects, which are appropriate for as many as eight different outputs: MainSpeakers (HF & LF), Balcony Speakers, Under-Balcony Speakers, Stage Monitors (1 & 2), Recording, and Hearing Assistance. Eightdigital audio feeds, from mixing console outputs and other 'playback' devices, are connected to inputs of the AudiaEXPI-D unit, which islocated near the mixing console. These signals are then sent via CobraNet to the AudiaFLEX unit, which is located backstage. TheAudiaFLEX unit provides all necessary signal processing for each of the system outputs, before feeding an MCA8150 power amplifierlocated in the same equipment rack.The MCA8150 amplifier uses four channels bridged in pairs, creating two outputs of 300 watts each. These outputs are driving the Mainspeaker systems (HF & LF). The MCA8150 amplifier also uses four individual channels, of 150 watts each, to drive the Balcony, Under-Balcony, Monitor 1, & Monitor 2 speaker systems. TDT150 transformers are installed internally for the outputs driving the Balcony andUnder-Balcony systems, which are utilizing 70V distributed speakers.The AudiaFLEX unit also provides eight channels of digital audio, via CobraNet, to the AudiaEXPO-D. The AudiaEXPO-D then providesdigital audio outputs at a broadcast/media feed panel.CobraNet from the three AUDIA units is tied together through an Ethernet switch. This allows sharing of digital audio signals on a network.The maximum distance between any AUDIA unit and an Ethernet switch is 300 feet. Therefore, this system can span up to 600 feetbetween the backstage and mixing locations. Additional Ethernet switches, or even fiber-optics, can be used to further extend distancesbetween units on the network. An added benefit to CobraNet is that it affords the necessary isolation to help avoid ground loops betweenactive components in different locations. CobraNet also saves on the labor and expense of wiring, by transmitting eight channels of digitalaudio over a single CAT5 cable.Of course, all live mixing is done at the console. The AUDIA network provides transportation, routing, and processing of the signals.AudiaEXPI-D and AudiaEXPO-D units act as a 'digital snake', transmitting digital audio between the backstage, mixing, andbroadcast/media feed locations. The AudiaFLEX unit provides routing and signal processing for the various outputs. In the exampledesign, parametric EQ and comp/limiting are employed at all speaker outputs. Main outputs include a 2-Way Crossover (separate highfrequency& low-frequency drivers). Balcony and Under-Balcony outputs include Delay compensation. Recording, Hearing Assistance,and Broadcast/Media outputs are processed simply with Levelers (for automatic control of recording/broadcast signal levels).Various remote control options are available. Volume 8, Select 8, and Volume/Select 8 rotary encoder panels may be used to providevolume adjustments and preset selections. A Logic Box allows system control via external switches, or control of external equipment fromthe system itself.6
