Introduction

Control Dialogs

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 Nexia 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.

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 Nexia 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.

Nexia-Manual-A4

When the user first places a Source Selection

block into an Nexia 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

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).

Level

Mute turns on/off the channel. Channel level may

be entered numerically, or may be adjusted by

dragging the fader. Maximum and Minimum can

be used to restrict the range of level adjustment

provided by the fader. Level ID provides a custom

label, when the dialog box is minimized (see

below).

Right-clicking over certain settings will provide a

menu of additional options. Control Dialog Boxes

for Level Control components can be minimized

to create user control surfaces (see Customizing

Component Objects).

When placed from the Object Toolbar, multiple

Level Controls may be 'ganged' together onto a

single fader. Ganged Level Controls display a 'G'

in the upper-right of the Component Object, and

Level ID colors are reversed on the Control

Dialog. Non-ganged Level Controls have a

maximum of 16 channels, whereas ganged Level

Controls have a maximum of 32 channels.

Introduction

Level Inc/Dec

Level Inc/Dec blocks are identical to Level blocks,

except they also provide control input nodes for

making incremental level changes. Inc/Dec Step

determines the amount of level change to occur

each time the associated control node is

triggered. Control input nodes along the top of the

block are labeled as positive (+) and negative (-).

When triggered by control output nodes on other

components within the layout design, positive

nodes produce a single-step increase in level

("Increment") and negative nodes produce a

single-step decrease in level ("Decrement").

When placed from the Object Toolbar, multiple

Level Inc/Dec Controls may be 'ganged' together

onto a single fader. Also, ramping may be

enabled at this time. When ramping is enabled,

Inc/Dec Rate sets timing (mS) between repetitive

incremental changes (Inc/Dec Steps) which occur

automatically as long as the associated control

node (+ or -) remains triggered.

Invert

Invert reverses the polarity of the audio signal (180°). Identifier

provides a custom label, when the dialog box is minimized (see below).

Right-clicking over certain settings will provide a menu of additional

options. Control Dialog Boxes for Invert components can be minimized

to create user control surfaces (see Customizing Component Objects

When placed from the Object Toolbar, multiple Invert channels may be

'ganged' together onto a single control. Ganged Invert controls display a

'G' in the upper-right of the Component Object, and Identifier colors are

reversed on the Control Dialog. Non-ganged Invert controls have a

maximum of 16 channels, whereas ganged Invert Controls have a

maximum of 32 channels.

Mute Button

Mute turns on/off the channel. Identifier provides a custom label, when

the dialog box is minimized (see below).

Right-clicking over certain settings will provide a menu of additional

options. Control Dialog Boxes for Mute Button components can be

minimized to create user control surfaces (see Customizing Component

Objects).

When placed from the Object Toolbar, multiple Mute Buttons may be

'ganged' together onto a single button. Ganged Mute Buttons display a

'G' in the upper-right of the Component Object, and Identifier colors are

reversed on the Control Dialog. Non-ganged Mute Buttons have a

maximum of 16 channels, whereas ganged Mute Buttons have a

maximum of 32 channels. Also, Mute Button blocks may be placed with

control input nodes selected.

Preset Button

Right-clicking over a button provides a list of available

Presets

which can be assigned to that button. The Preset

Number will appear on the button, and the Preset Name will

appear to the right. Preset Numbers can be replaced with

the word 'Recall' (see General Options

). Control Dialog

Boxes for Preset Button components can be minimized to

create user control surfaces (see Customizing Component

Objects).

Remote Preset Button

Remote Preset Buttons are identical to Preset Buttons,

except they have control input nodes on the block. These

control input nodes allow presets to be recalled via control

output nodes on other component blocks. This provides

remote control of preset selection, both from internal

components and external controls. Unlike most other

blocks, multiple control output nodes may be connected to

a single control input node on a Remote Preset Button.

Control Dialog Boxes for Remote Preset Button

components can be minimized to create user control

surfaces (see Customizing Component Objects
