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
