Introduction
AudiaFUSION
.AudiaFUSION Networked Amplified Processor is an 8-channel modular amplifier with CobraNet
digital I/O, digital signal processing, and automatic channel or device failover. The device
provides amplified outputs to directly drive 4, 6, or 8 Ohm low-impedance loudspeaker systems or
70 or 100V constant voltage loudspeaker systems. When placed into the layout from the Object
toolbar, AudiaFUSION output blocks are software configurable for 100–600 watts per channel.
The combined wattage of all power amplifier modules in an AudiaFUSION chassis can be up to
2400 watts.
Initialization Properties
An AudiaFUSION unit appears in Audia software as an output block. When an AudiaFUSION
device is chosen from the I/O menu in the Object toolbar and the mouse is clicked in the layout
window, an AudiaFUSION Amp Initialization Dialog window appears.
Channel Power is used to select the power rating (in watts) for all channels controlled by that
block.
Channel Count is used to select the number of amplifier channels that block will provide. The
maximum number of channels available with this parameter is affected by the Channel power
setting. For example, a setting of 600 watts would result in a maximum Channel count of 4, as
600 watts x 4 channels = 2400 watts, which is the maximum amplifier capacity of one
AudiaFUSION frame.
Enable Logic Outputs is used to determine if the AudiaFUSION block will provide logic output
connection points.
1
Audia-Manual-LTR
Group Logic Outputs is used when Enable logic outputs is checked to determine what
complement of logic outputs are provided on the AudiaFUSION block. If Group logic outputs is
unchecked, the block will feature six logic outputs per channel, plus a global Fan Stuck Rotor
output. The six logic outputs for each channel correspond to the six fault types that an
AudiaFUSION amplifier channel can report: Heat Sink, Short Circuit, Channel Failure, Excessive
Clipping, Low Impedance, and High Impedance.
If Group Logic Outputs is checked, only two logic outputs are provided per amplifier channel,
Alarm and Warning, plus the global Fan Stuck Rotor. In this mode, the Alarm output is a logical
OR of the Heat Sink, Short Circuit, and Channel Failure Alarms. The Warning output is a logical
OR of the Heat Sink, Excessive Clipping, Low Impedance, and High Impedance Warnings. If an
AudiaFUSION block is initialized with Device Failover active, two additional global logic outputs
are provided, Primary Device Good and Secondary Device Good.
Amplifier Mode is used to specify whether the amplifier channels controlled by that block will be
configured as Low Impedance – for standard 4, 6, or 8 Ohm loudspeakers – or 70V or 100V
Constant Voltage – for connection to distributed, transformer-coupled loudspeakers.
Enable Device Failover is used to establish an automatic device failover mode using two
identically configured AudiaFUSION units. The two units become a logical pair and are referred
to as the Primary Device and Secondary Device. If the Primary Device experiences an alarm, it
will automatically transfer control to the Secondary Device, which will continue to process and
distribute audio, taking on all of the functions of the Primary Device.
When device failover occurs, switching relays on the AM600 amplifier modules will physically
break loudspeaker connections on the Primary Device and make connections on the Secondary
Device. As a result, it is necessary to have two physical cable runs to each loudspeaker
connection, one from the Primary Device and one from the corresponding output channel on the
Secondary Device, in order for audio to continue to flow when device failover occurs.
When an AudiaFUSION block is created with Enable Device Failover checked, it will appear in
the layout window as two devices “fused” together. The properties and attributes of the
Secondary Device cannot be edited or modified independently of the Primary Device. The two
units are always configured identically.
When a layout is compiled that includes an AudiaFUSION block with device failover enabled, the
Secondary Device will receive a device ID that is different from the Primary Device; however,
during a failover, any received ATP command strings intended for the Primary Device are
automatically routed to the Secondary Device, and any acknowledgement messages that the
Secondary Device returns will contain the device ID of the Primary Device, even though the
Primary Device is no longer the active unit. This preserves third-party control support during
device failover.
A device failover pair will appear in the Equipment Table with device types that are read-only. If
either the Primary or Secondary Device is removed from the Equipment Table, the partner unit
will also be removed.
Enable Channel Failover for these Channels provides a means of establishing an automatic
channel failover mode using two adjacent channels within a single AudiaFUSION unit. The two
designated channels become a logical pair and are referred to as Primary Channel and
Secondary Channel. If the Primary Channel experiences a channel alarm, it will automatically
transfer control to the Secondary Channel, which will continue to process and distribute audio,
taking on all of the functions of the Primary Channel.
When channel failover occurs, switching relays on the AM600 amplifier modules will physically
break loudspeaker connections on the Primary Channel and make connections on the Secondary
Channel. As a result, it is necessary to have two physical cable runs to each loudspeaker
connection, one from the Primary Channel and one from the Secondary Channel, in order for
audio to continue to flow when channel failover occurs.

Introduction
When failover occurs, any received ATP command strings intended for the Primary Channel are
automatically routed to the Secondary Channel, and any acknowledgement messages that the
Secondary Channel returns will contain the index value of the Primary Channel, even though the
Primary Channel is no longer the active channel. This preserves third-party control support
during channel failover.
Note: Channel failover is not available when Device failover is being used, and vice versa.
AudiaFUSION Block
The AudiaFUSION block provides connection points for audio coming into the block, and logic
output connection points for fault indications.
If channel failover is in use, the Primary Channel will be indicated with (P) and the Secondary
Channel with (S). The connection point for the Secondary Channel will appear in a light gray
color and will not accept a wire connection. Instead, the audio signal connected to the Primary
Channel will automatically be used as the input for the Secondary Channel when channel failover
occurs.
If device failover is in use, the block will appear as two AudiaFUSION blocks “fused” together.
The Primary (left) side will have the audio and logic connection points and the Secondary (right)
side will have no connection points.
The complement of logic output connection points that are available is dependent on whether the
Group Logic Outputs property in the AudiaFUSION block initialization dialog window is checked
or not. When that setting is unchecked, the block will feature six logic outputs per channel, plus a
global Fan Stuck Rotor output. The six logic outputs for each channel correspond to the six fault
types that an AudiaFUSION amplifier channel can report: Heat Sink, Short Circuit, Channel
Failure, Excessive Clipping, Low Impedance, and High Impedance.
If Group Logic Outputs is checked, only two logic outputs are provided per amplifier channel,
Alarm and Warning, plus the global Fan Stuck Rotor. In this mode, the Alarm output is a logical
OR of the Heat Sink, Short Circuit, and Channel Failure Alarms. The Warning output is a logical
OR of the Heat Sink, Excessive Clipping, Low Impedance, and High Impedance Warnings. When
the AudiaFUSION block is initialized with Device Failover active, two additional global logic
outputs are provided, Primary Device Good and Secondary Device Good.
AudiaFUSION Control Dialog Window

Audia-Manual-LTR
Device I/O indicates which hardware input is associated with that software channel. If Device
failover or Channel failover is in use, an additional column to the right of the Device I/O field will
indicate whether that device or channel is Primary (Pri) or Secondary (Sec).
Fault
There are two types of Faults that the AudiaFUSION can report, categorized as Warnings or
Alarms, depending on their severity. A Warning indicates that some aspect of the system is not
performing within normal specification. Audio is still passing, but if the condition causing the
Warning is not corrected, failure may occur. An Alarm indicates that some aspect of the system
has failed and audio is no longer passing on that channel. If Channel or Device Failover has
been enabled for that channel or device, an Alarm will cause failover to occur, whereas a
Warning will not.
List of AudiaFUSION Faults:
Heat Sink (HS) Warning indicates that the heat sink on the AM600 amplifier module has
reached 92% of its maximum cooling capacity. The amplifier module will automatically
attenuate audio by 3 dB to attempt to reduce the temperature of the heat sink. If the
temperature continues to rise, the HS Warning will become an HS Alarm (see below).
The heat sink temperature must fall below 84% of maximum capacity to clear the HS
Warning and restore full output level.
Heat Sink (HS) Alarm indicates that the heat sink on the AM600 amplifier module has
reached 100% of its cooling capacity and audio on that channel will be stopped. Failover
will occur if enabled on that channel or device. If failover is not enabled, audio will only
be restored on that channel when the heat sink temperature falls below 84% of maximum
capacity.
Short Circuit (SC) Alarm indicates that there may be a short circuit on the load on that
channel. The output current of the amplifier module is continuously monitored. If the
current exceeds the maximum rated current amount, or if the load impedance monitoring
circuit calculates an effective load of 1 Ohm or less, the SC Alarm will occur and audio
will be stopped on that channel. After a brief wait, the amplifier module will attempt to
restart audio. If the condition that caused the SC Alarm persists, the amplifier module will
continue to wait and try again. It will do this indefinitely, unless failover has been enabled
on that channel or device, in which case the Short Circuit Delay attribute in the Property
Sheet of the AudiaFUSION block will determine how long the amplifier module will retry
before failover occurs.
4
Introduction
Channel Failure (CF) Alarm indicates that a hardware failure of the amplifier module
has occurred. Audio will be stopped on that channel and channel or device failover will
occur, if enabled.
Excessive Clipping (EC) Warning indicates that amplifier output clipping has occurred
(or would have occurred if the Clip Limiter had not been enabled) and is affected by the
Clip Count Threshold parameter (see Clip Count Threshold below).
Low Impedance (LZ) Warning indicates that the impedance monitoring circuit (if
enabled) has detected an impedance that is lower than the minimum allowed by the
current setting of the Tolerance parameter (see Band Setup below).
High Impedance (HZ) Warning indicates that the impedance monitoring circuit (if
enabled) has detected an impedance that is higher than the maximum allowed by the
current setting of the Tolerance parameter (see Band Setup below).
Other Control Dialog Parameters
HS Temp % Max indicates the temperature of the heat sink located on the amplifier module,
given as a percentage of maximum cooling capacity. If the heat sink temperature rises to 92%, a
Heat Sink (HS) Warning will occur and the amplifier module will attenuate its output by 3 dB to
attempt to reduce the temperature of the heat sink. If the heat sink temperature rises to 100%, a
Heat Sink (HS) Alarm will occur and audio on that channel will be stopped.
Clip Count Threshold is the number of consecutive 100 ms segments of audio containing at
least one clipped sample that are needed to illuminate the Excessive Clipping (EC) Warning
indicator. The Clip Count Threshold affects the response of the EC Warning indicator; if the Clip
Count Threshold is set to 1, the Excessive Clipping (EC) Warning indicator becomes a “standard”
or instantaneous clip indicator, rather than an “excessive” or long-term clip indicator.
Mute Out is used to mute the audio on that channel. Gain Out (dB) is used to set the amplifier
sensitivity. This control ranges from 0 dB (unity gain) to 24 dB (default is 12 dB). Invert Out is
used to reverse the polarity of the output signal. Clip Limiter Out is used to control whether the
analog clip limiting circuit on the amplifier module is enabled or not. When enabled, this limiter
attenuates any signal peaks that would otherwise cause the amplifier’s output to clip. Peak Out
is a signal peak indicator that illuminates when the output signal is within 3 dB of clipping the
amplifier.
Impedance Parameters
Load is a setting that allows the user to select the intended speaker load (4, 6, or 8 Ohm) for all
channels controlled by that block. Choosing Auto Detect will allow the AM600 amplifier module to
automatically set the load impedance based upon the amplifier output current. This setting is only
available if the Amplifier Mode has been designated as Low Impedance. (See Amplifier Mode
above)
Band Setup produces a control dialog window that allows the Impedance Monitoring algorithm to
be configured. The text on the button control will indicate the number of frequency bands that
have been defined for impedance monitoring.
Impedance Monitoring Active (IMA) is an indicator that illuminates when impedance monitoring
is active.
Frequency Band Setup
5
Audia-Manual-LTR
Frequency Band Setup is a dialog window that contains parameters for defining frequency
bands over which impedance monitoring should occur. Up to four bands can be defined. Active
Band is used to choose which band’s parameters are displayed for modification. Center Freq
(Hz) is the center frequency of the active band. Bandwidth (Hz) is the bandwidth of the active
band. Tolerance % defines the amount above or below the baseline impedance curve that,
when exceeded, causes a High Impedance or Low Impedance Warning to occur. Setting
Tolerance % to a lower number means that a smaller change in the load impedance curve will be
sufficient to cause a High Impedance or Low Impedance Warning. Setting Tolerance % to a
higher number means that a larger change in the load impedance curve will be required to cause
a High Impedance or Low Impedance Warning.
Add Band is used to add an additional band to the monitoring algorithm. Up to four bands can
be defined. Remove Band will delete the highest-numbered band. Disable Alarms is used to
bypass the impedance monitoring algorithm and suppress any High Impedance or Low
Impedance faults that may be detected. Averaging length (samples) defines the number of
impedance measurements that are collected and averaged to determine the load impedance
curve. Setting this value to a lower number will allow the curve to be drawn and updated more
quickly, at the expense of some accuracy or “curve jitter.” Setting this value to a higher number
will cause the curve to be drawn and updated more slowly, but with smoother and more accurate
data.
Capture Alarm Baseline Data is used to populate the Alarm Baseline Data fields with the
currently displayed Realtime Impedance Data. The Realtime Impedance Data is obtained by
dynamically measuring load voltage versus current at several different frequencies throughout the
audible spectrum. The results of this impedance calculation are affected by the amplitude and
spectral characteristics of the signal passing through the amplifier module. For best results, a
wideband signal such as pink noise should be played at a sufficient level to overcome the noise
floor of the detection circuitry.
Impedance Monitoring Active is an indicator that illuminates when sufficient data has been
entered for the impedance monitoring algorithm to begin monitoring that band.
Auto Mixer Combiner
Note: The Auto Mixer Combiner replaces the Mix Minus Combiner in the software and incorporates all of its functionality,
plus some additional features. Files created in previous versions of Audia that contain a Mix Minus Combiner will still
function normally and the Mix Minus Combiner will still appear in the layout, even though the block will no longer appear in
the Object Toolbar or Processing Library. The user may substitute an Auto Mixer Combiner block anywhere a Mix Minus
Combiner would have been used.

Introduction
Auto Mixer Combiner blocks enhance the capabilities of Auto Mixers in room
combining, mix-minus, and input expansion applications. Auto Mixer Combiners
combine control data only and, therefore, have no audio outputs. Inputs to an Auto
Mixer Combiner come from the Mix outputs of separate Auto Mixer blocks. Ch /
Combine allows input channels (1, 2, 3, etc.) to be grouped into specific combinations
(A, B, C, etc.). These combinations automatically determine proper routing of control
data for the Auto Mixer blocks. Control data represents NOM (number of open mics),
ATS (adaptive threshold sensing), and last mic hold status information. Auto Mixer
Combiners are used when Auto Mixer outputs are also connected to a separate Matrix
Mixer (to create multiple mix-minus outputs). Auto Mixer Combiners allow large Auto
Mixers to be created from multiple, smaller ones. This is useful when more than 32
inputs are required or when an Auto Mixer must be placed into multiple Audia units (for
proper DSP allocation or physical location of inputs).
Groups buttons are used to choose a group for viewing and editing two settings: Last
Mic Hold and Open Mic Limits. Last Mic Hold determines whether the last open
microphone across all Auto Mixer inputs assigned to the current group is allowed to
gate off when activity on that channel ceases. Open Mic Limits enables (and
designates) a maximum allowable number of active microphones across all Auto Mixer
inputs assigned to the current group.
Right clicking on Ch / Combine assignments will prompt a menu of additional options.
Source Selections
Source Selection blocks are N by 1 routers (where N represents the number of sources) with level control per input and
optional logic input and output connections. Source Selection blocks are useful when remote control of audio source
selection is required.
When the user first places a Source Selection
block into an Audia layout, this prompts an
initialization window.
Source Channel Count specifies the number of input
channels (2 to 16) and generally corresponds to the
number of sources from which the user can choose. If the
Source Channel Count is set to Custom, the Chan Count
parameter is used to specify the exact number of
channels desired.
If selected, Enable Logic provides a logic input and output
connection point for each channel.
Source Selection is represented in the layout
as a block with a number of audio input
connections (specified by the Source Channel
Count parameter), one audio output
connection, and optionally, a logic input and
output connection point for each channel. If
logic is enabled, a low-to-high logic transition
(i.e., a rising edge) presented to a logic input

Audia-Manual-LTR
RED-1
connection will cause the Source Selection
block to switch to the corresponding audio
input channel, and the corresponding logic out
connection will be at a logic high. All other
logic outputs will be low.
Double clicking on a Source Selection block produces a
control window.
Level (dB) adjusts the level (-100 to 12 dB) of the source
connected to that channel’s input.
Source Selection buttons are used to select the input
source that is routed to the audio output connector of the
Source Selection block. If the user right clicks a source
selection button, this produces a dialog box that allows
customization of the text that is displayed on that button.
This dialog box can be minimized to create user control
surfaces (see Customizing Component Objects).
Remote Ethernet Device 1 (RED-1) is an external remote control panel that integrates with Audia systems via Ethernet,
using a single CAT5 cable for control and Power-over-Ethernet (PoE). RED-1 allows for the selection of up to 32 control
items. A control item can be the initiation of a logic event (such as a preset recall or a source selection), selection of a
volume assignment, or both. Volume assignments may be individual or ganged levels within the layout, including Level
Control blocks, as well as levels within other component blocks (such as Input/Output blocks, Mixers, Equalizers, etc).
When a RED-1 block is first placed into the layout, an
initialization dialog box appears.
Logic Out specifies the number of logic connection
points (0 to 32) on the RED-1 block. These connection
points are typically wired to Remote Preset or Source
Selection blocks but can also be used as generalpurpose logic inputs.
Device ID is the name given to each RED-1 block and
should correspond to the Device ID of a physical remote
panel. No two RED-1 blocks in any layout may have the
same Device ID; however, multiple RED-1 panels may
have the same Device ID. In that case, the panels’
functions are identical and governed by the RED-1
block with the corresponding Device ID.
RED-1 is represented in the layout as a
block with a number of logic connection
points (determined by the Logic Out setting
when the block is created), plus a DF logic
output node, which outputs logic high when
at least one like-named RED-1 unit is
discovered on the network.

Introduction
All programmed panel functions are assigned using the control dialog box, which is produced by double-clicking the RED1 block.
A list displays all defined control items, each with a Channel Number and customizable Control Label. The New button
creates a control item in the list, and the user is prompted to either accept the default label or enter a new one. Rename
allows the user to change the Control Label of the selected control item. Delete removes the selected control item from
the list. Move Up and Move Down modify the order of the control items in the list, giving the user the ability to control the
display order of the control items on the RED-1 panel.
Each control item may have a Level Control assignment, a Logic Control assignment, or both.
Level Control
Object Code selects from a list of blocks found in the layout, and the Instance ID is entered automatically, if known.
Control ID selects from a list of available levels within the chosen block.
Logic Control
Logic Index specifies which logic connection point, if any, on the RED-1 block will be triggered when that control item is
selected.
Once the RED-1 block has been programmed with control items, the Select and Up/Down Arrow buttons at the bottom of
the control dialog box may be used to mimic how the control will function from the physical panel.
Control dialog boxes for RED-1 devices may be minimized to create user control surfaces (see Customizing Component
Objects).
