Digital Inputs: The four female XLR connectors provide a total of eight AES3 digital audio inputs in channel pairs (1-2, 3-4, 5-6, 7-8).
AES3 inputs are transformer coupled and should be wired using 110 ohm shielded-pair digital audio cable, with pin 2 (+), pin 3 (-), & pin 1
(ground). 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 matching 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.

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 high-
frequency & 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.
