AudiaEXPI-D accepts eight channels of digital audio input and provides eight channels of digital audio output via CobraNet. AudiaEXPI-D can simply add inputs to a centralized system, or it can extend system boundaries by providing inputs in remote locations. AudiaEXPI-D is represented as a block in AUDIA software, for easy inclusion into any system design. AudiaEXPI-D may also be used to provide inputs to other CobraNet compliant systems or devices. AudiaEXPI-D features include: 4 digital input pairs on (xfmr coupled) SPDIF digital inputs on RCA (channels 1-2 & 3-4) TOSLINK digital inputs (channels 5-6 & 7-8) 8 channels of digital audio output via CobraNet Word Clock output on BNC connector rotary encoder with LCD for programming/setup logic inputs for recalling preset configurations included as block in AUDIA system design software may be used with any CobraNet compliant system CE marked and UL listed power source AudiaEXPO-D is a digital output expander for AUDIA, the benchmark in digital audio systems for demanding professional sound installations.

Input pairs 1-2 & 3-4 may each be selected for SPDIF input, and input pairs 5-6 & 7-8 may each be selected for TOSLINK input (see Rotary Encoder above). SPDIF inputs are provided on RCA jacks and should be wired using 75 ohm coaxial cable, with Tip (+) and Sleeve (ground). TOSLINK inputs utilize optical digital audio patch cables. Word Clock Out: This BNC connector provides clock output from either CobraNet or a selected input source (see Rotary Encoder above). Logic Inputs: These eight Logic Inputs allow remote control of preset configurations. Preset configurations may be assigned to Logic Inputs 1~8 using the front panel Rotary Encoder (see above), and can then be selected via external contact-closures (wired from the corresponding logic inputs to ground). CobraNet: These two RJ45 connectors provide the CobraNet digital audio interface. CobraNet allows multiple AUDIA units to share digital audio (and DSP resources) on a system network. This also allows AUDIA units to be used with CobraNet compliant devices from other manufacturers. 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. The primary and secondary CobraNet ports are redundant. CobraNet supports 64 channels 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 where digital audio is transmitted and received. Typically, 'unicast' bundle numbers (256~61,439) are used to exchange digital audio between two specific 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 limitation of seven (7) 'hops' (one-way transmissions) within a network. In order to integrate AudiaEXPI-D into a AUDIA system, an EXPI-D (or CobraNet) input block must first be placed into the design layout. AUDIA units intended to receive digital audio from the AudiaEXPI-D must have their CobraNet jacks connected to the same network. Both the AudiaEXPI-D unit (hardware) and the EXPI-D input block (software) must be assigned ing bundle numbers, before digital audio can be successfully exchanged. AudiaEXPI-D bundle number assignment can be changed in real-time to allow routing of digital audio to different EXPI-D input 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 route digital audio to individual or multiple EXPI-D input blocks. Similar considerations may also apply when using AudiaEXPI-D with other CobraNet compliant systems or devices. AudiaEXPI-D and AudiaEXPO-D can exchange digital audio directly (outside of a system network) using either a simple 'cross-over' CAT5 cable or an Ethernet switch. 2

8 APPLICATION This application demonstrates the use of AUDIA in a house of worship. This is a networked system using one AudiaFLEX 8-Output CM unit, an AudiaEXPI-D 8-Input Digital Expander unit, and an AudiaEXPO-D 8-Output Digital Expander unit (eight digital inputs, eight digital outputs, eight analog outputs, CobraNet). An example system diagram is shown on the opposite page, and a representative design layout is 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-House mixing position. The console provides multiple mixes, including effects, which are appropriate for as many as eight different outputs: Main Speakers (HF & LF), Balcony Speakers, Under-Balcony Speakers, Stage Monitors (1 & 2), Recording, and Hearing Assistance. Eight digital audio feeds, from mixing console outputs and other 'playback' devices, are connected to inputs of the AudiaEXPI-D unit, which is located near the mixing console. These signals are then sent via CobraNet to the AudiaFLEX unit, which is located backstage. The AudiaFLEX unit provides all necessary signal processing for each of the system outputs, before feeding an MCA8150 power amplifier located 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 Main speaker 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 and Under-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 provides digital 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 feet between the backstage and mixing locations. Additional Ethernet switches, or even fiber-optics, can be used to further extend distances between units on the network. An added benefit to CobraNet is that it affords the necessary isolation to help avoid ground loops between active components in different locations. CobraNet also saves on the labor and expense of wiring, by transmitting eight channels of digital audio 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, and broadcast/media feed locations. The AudiaFLEX unit provides routing and signal processing for the various outputs. In the example design, 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 provide volume adjustments and preset selections. A Logic Box allows system control via external switches, or control of external equipment from the system itself. 6
