Peak Indicators (Inputs 1~8): These red LEDs will light whenever input channel signal levels reach +14dB (6dB below clipping). Use this
feature to aid in the adjustment of the Trim controls (see below).
Trims (Inputs 1~8): These screw-driver adjustable controls set the channel input gain (0dB ~ +60dB) to compensate for different source
levels. This gain range will accomodate most microphone or line level signals. For best performance, adjust these controls so the channel
Peak Indicators flash only on occasional peaks.
Rotary Encoder & LCD Display: This control and display are used for initial setup of the AudiaEXPI 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 bundle
number to logic input assignments); COBRANET LATENCY (dependent upon CobraNet firmware); PHANTOM POWER (assigns
phantom power to inputs); PASSWORD PROTECT (prohibits unauthorized tampering); TITLE DISPLAY (personalized: 2 lines with 8
characters each); ABOUT (serial#, version#, and Ethernet address information).
Mic/Line Inputs: These eight mic/line analog audio inputs are provided on balanced plug-in barrier-strip connectors. For unbalanced
input, wire high to (+) and ground to both (-) & (
d
). For use with condenser microphones, +48 volt phantom power is available at these
inputs (see Rotary Encoder above).
Logic Inputs: These eight Logic Inputs allow remote control of CobraNet bundle number assignment (see CobraNet below). Bundle
numbers can be assigned to Logic Inputs using the front panel Rotary Encoder (see above), and can then be selected via external contactclosures (wired from the corresponding logic inputs to ground). Bundle numbers are used to route digital audio signals to specific devices
in a system network.
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 into a AUDIA system, an EXPI (or CobraNet) input block must first be placed into the design layout.
AUDIA units intended to receive digital audio from the AudiaEXPI must have their CobraNet jacks connected to the same network. Both
the AudiaEXPI unit (hardware) and the EXPI input block (software) must be assigned matching bundle numbers, before digital audio can
be successfully exchanged. AudiaEXPI bundle number assignment can be changed in real-time to allow routing of digital audio to different
EXPI 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 input blocks. Similar considerations may also apply when
using AudiaEXPI with other CobraNet compliant systems or devices. AudiaEXPI and AudiaEXPO can exchange digital audio directly
(outside of a system network) using either a simple 'cross-over' CAT5 cable or an Ethernet switch.

APPLICATIONS
Hotel with Sound Reinforcement in Multiple Banquet/Conference Rooms
This application demonstrates the use of AUDIA in a
hotel conference/banquet facility. This is a
networked system using one AudiaFLEX 10x12CM
left
stereo
speaker
unit and three AudiaEXPI 8-Input Expander units
(forty-two inputs, twelve outputs, CobraNet). An
example system diagram is shown on the next page.
Each room has four microphones and two stereo line
inputs, which are connected to an AudiaEXPI located
within the room. This is beneficial because stereo
line input signals are typically 'unbalanced' and, as
such, should not be routed over long distances. The
AudiaEXPI converts these signals to digital audio,
and transmits them back to the main equipment rack
via CobraNet. Additionally, CobraNet affords the
necessary isolation to help avoid ground loops
stereo
input

left
stereo
speaker
between active components within the individual
rooms and back at the main equipment rack.
CobraNet also saves on the labor and expense of
wiring, by transmitting all signals from a given room
over a single CAT5 cable.
Only three of the rooms utilize an AudiaEXPI locally.
The fourth room houses the main equipment rack,
which includes an AudiaFLEX 10x12CM. The
AudiaFLEX unit accommodates the eight inputs from
stereo
input
#1
this room, as well as two inputs from centralized
paging and background music. The AudiaFLEX unit
also provides twelve system outputs: mono speech
and stereo program for each of the four rooms.
These outputs are feeding the two MCA8050 multichannel amplifiers.
One MCA8050 amplifier has eight channels which are operating as four stereo pairs, providing up to 50 watts per channel to drive the
stereo program speakers in each of the four rooms. The other MCA8050 amplifier has eight channels which have been bridged in pairs,
essentially creating four channels of 100 watts each. With four TDT100 transformers installed internally, this MCA8050 is prepared to drive
the (speech related) 70 volt distibuted speaker system in each of the four rooms.
CobraNet from the AudiaEXPI units to the AudiaFLEX unit is tied together through an Ethernet switch. This allows sharing of digital audio
signals (CobraNet) 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 main equipment rack and any of the rooms. Additional Ethernet switches, or even fiberoptics, can be used to further extend distances between units on the network.
All mixing and processing of signals is done back at the AudiaFLEX unit in the main equipment rack. In the system design, each room is
provided with an Auto Mixer (4x1) for the microphones and a Router (4x2) for stereo source selection. A Room Combiner allows proper
sharing of audio and control data amongst the Auto Mixers, and a Matrix Mixer (8x8) is provided to facilitate proper stereo source routing
for each of the various room configurations. Duckers allow page-override of local and backgound music signals. Levelers are utilized on
all microphone inputs (to provide consistent volume levels), and equalizers are utilized at all outputs (to compensate for room acoustics
and enhance intelligibility).
Various remote control options are available. Volume 8, Select 8, and Volume/Select 8 rotary encoder panels may be used to provide
volume, source selection, and even room combining functions. A Logic Box could instead provide room combining via external switches
(on the room partitions or on a custom control panel), and would also allow control of external equipment (such as lighting, speakers,
sources, etc.). Control behavior is programmable, and can be made to change automatically to fit different system configurations. For
example, volume control and source selection can follow room combining.

APPLICATIONS
Courthouse with Multiple Courtrooms and Hard-Disk Court Recording
This application demonstrates the use of AUDIA in a
modern courthouse. This is a networked system
using two AudiaFLEX 20x4CM units and two
AudiaEXPO 8-Output Expander units (forty inputs,
twenty-four outputs, CobraNet). An example system
diagram is shown on the next page.
Each courtroom is shown as having ten
microphones. AUDIA inputs accept microphone or
line-level signals equally well, so some inputs could
instead be from sources such as playback of
recorded evidence. Inputs from the four courtrooms
are connected to the two AudiaFLEX units, which are
located in a local equipment closet. Each
AudiaFLEX unit accommodates inputs from two of
the courtrooms, and provides four system outputs.
In this case, one unit provides the outputs necessary
to feed a hearing assistance system in each of the
courtrooms. The other unit is providing the outputs
needed for sound reinforcement. These outputs are
feeding an MCA8050 multi-channel amplifier.
The MCA8050 amplifier has eight channels which
have been bridged in pairs, essentially creating four
channels of 100 watts each. With four TDT100
transformers installed internally, the MCA8050 is
prepared to drive the 70 volt distibuted speaker
system in each of the four courtrooms.
CobraNet and Ethernet from both AudiaFLEX units
are tied together through an Ethernet switch. This
allows sharing of digital audio signals (CobraNet)
4-track
hard-disk
court recorder
and control data (Ethernet) on a network.
Connected to the same Ethernet switch, and
functioning as part of the same network, are two
AudiaEXPO units. These two AudiaEXPO units are
physically located in a central computer/recording office. 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 equipment closet and the computer/recording office. Additional Ethernet
switches, or even fiber-optics, can further extend distances between units on the network.
Each AudiaEXPO receives eight channels of digital audio via CobraNet, over a single CAT5 cable. These eight channels of digital audio
are then converted to analog audio, and appear on eight separate output connections. Each AudiaEXPO provides the appropriate
channels of audio for two of the four court recording systems. Mixing and processing of these signals (to achieve proper microphone/track
assignment and consistent recording levels) has already be accomplished back at the AudiaFLEX units.
Design example: Recording signals are not gated or equalized, but Levelers are employed to ensure consistent levels and intelligibility.
Matrix Mixers used to provide the following input-to-track assignments: Judge & Sidebar (track 1); Witness, Evidence, & Clerk (track 2);
Defense, Prosecution, Podium, & Wireless (track 3); Jury (track 4). Mixing and processing of signals for hearing assistance and sound
reinforcement have also been accomplished within the AudiaFLEX units. These are the same input signals that feed the recorders, but in
this case they are mixed and gated appropriately using Auto Mixers. Levelers are then utilized at these outputs (to provide consistent
output volume), and equalizers are utilized at the sound reinforcements outputs only (to compensate for courtroom acoustics).
Various remote control options are available. Volume 8, Select 8, and Volume/Select 8 rotary encoder panels may be used to provide
volume, override, sidebar, and other such functions. A Logic Box would allow individual microphone privacy switches and/or control of
external functions (such as camera presets or speaker relays). External switches can even be connected to the AudiaEXPO logic inputs,
to allow remote selection of courtroom-to-recorder assignments (via CobraNet bundle assignment).

eight zones on the first floor. An AudiaEXPO unit is
located on each of the other floors, and provides the
corresponding zone outputs for that floor.
The AudiaFLEX unit distributes the appropriate
signals to the AudiaEXPO units on the other floors
Zone 1
speakers
Zone 2

Zone 3
speakers
as digital audio via CobraNet. This is beneficial
because some of the input sources are 'unbalanced'
and, as such, should not be routed over long
distances. Additionally, CobraNet affords the
necessary isolation to help avoid ground loops
between the active components located on different
Zone 1
speakers
Zone 2
speakers
Zone 3
speakers
floors. CobraNet also saves on the labor and
expense of wiring, by transmitting all eight of the
associated zone output signals to a given floor over a
single CAT5 cable.
The zone outputs on each of the floors are
connected to an MCA8050 multi-channel amplifier,
central
paging
microphone
located in the same equipment rack as the
AudiaFLEX or AudiaEXPO unit. Each MCA8050
amplifier has eight channels, delivering 50 watts of
digital message repeater
power per channel. With eight TDT50 transformers
installed internally, each MCA8050 is prepared to
drive the eight 70 volt distibuted speaker systems on that floor.
CobraNet from the AudiaFLEX unit to the AudiaEXPO units is tied together through an Ethernet switch. This allows sharing of digital audio
signals (CobraNet) 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 first floor equipment rack and any of the other floors. Additional Ethernet switches, or even
fiber-optics, can be used to further extend distances between units on the network.
All mixing and processing of signals is accomplished within the AudiaFLEX unit on the first floor. In the system design, the paging
microphone is fed to a Router (1x32) for assignment to the individual zones. The message repeater is fed to a Router (1x4) for assignment
to the four floors. The two background music inputs are both fed to four separate Routers (2x1) for source selection on each of the four
floors. Telephone paging is fed to a set of four Duckers (one for each floor) to provide page-override of the selected background music on
that floor. Output from the message Router is fed to a second set of four Duckers (one for each floor) to provide message-override of the
telephone and music signals on that floor. Finally, output from the microphone Router is fed to a bank of thirty-two Duckers (one for each
zone) to provide master page-override of all other signals in any selected zones. Levelers are utilized on all paging and message inputs
(to provide consistent volume levels), and equalizers are utilized at all outputs (to compensate for building acoustics and enhance
intelligibility).
Various remote control options are available. Volume 8, Select 8, and Volume/Select 8 rotary encoder panels may be used to provide
volume, source selection, and even page routing functions. Two Logic Box control devices could instead provide forty logic inputs, which
would allow all page/message routing and music source selection to be accomplished using external switches on custom control panels.

APPLICATIONS
Theater with Live Mixing Console and Multiple Speaker Zones
This application demonstrates the use of AUDIA in a
live-performance theater. This is a networked
system using one AudiaFLEX 2x8CM unit, three
AudiaEXPI 8-Input Expander units, and two
AudiaEXPO 8-Output Expander units (twenty-six
inputs, twenty-four outputs, CobraNet). An example
system diagram is shown on the back page.
Sixteen stage microphones are connected to the
inputs of two AudiaEXPI units, which are located
backstage. These sixteen signals then appear at the
outputs of two AudiaEXPO units, which are located
near the mixing console. The console is used to mix
these signals (plus any local source signals, such as
effects and playback) to as many as eight different
outputs: Left/Center/Right (front-of-house), UnderBalcony (rear-of-house), Stage Monitors (1 & 2),
Lobby, and Backstage. These outputs are
connected to a another AudiaEXPI unit, which is
located near the mixing console. These eight signals
then appear backstage at an AudiaFLEX unit, which
provides signal processing for each of the outputs
before feeding MCA8050 and MCA8150 power
amplifiers located in the same equipment rack.
The MCA8050 amplifier has eight channels bridged
in pairs, creating four channels of 100 watts each.
These outputs are driving the Backstage, Lobby, and
Monitor speaker systems. The MCA8150 amplifier
also has eight channels which have been bridged in
pairs, providing four channels of 300 watts each.
These outputs are driving the Left/Center/Right and
Under-Balcony speakers. TDT300 and TDT100
transformers are installed internally for outputs
driving 70V distributed speaker systems.
The AudiaFLEX unit also receives input from an emergency paging microphone (located in the office), and from an announcement
microphone (located backstage). These two signals can be routed (with override capability) to any of the eight outputs. Example:
Emergency paging may be desired at all outputs, while announcements may be routed to the Lobby or Backstage as necessary. CobraNet
from the six 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 stage and mixing position. 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 and AudiaEXPO units act as a 'digital snake', transmitting digital audio between the stage and mixing position. The AudiaFLEX
unit provides routing and remote control capabilites, as well as signal processing for the speaker outputs. In the system design, the
emergency and announcement microphone inputs employ Levelers (for consistent volume), Routers (for output assignment), and Duckers
(for page-override). At the outputs, processing includes Equalizers (to compensate for acoustics), Comp/Limiters (to control peaks), and
Delays (for speaker zone alignment).
Various remote control options are available. Volume 8, Select 8, and Volume/Select 8 rotary encoder panels may be used to provide
volume, preset selection, and even page routing functions. A Logic Box allows system control via external switches, or control of external
equipment from the system.
