Nexia-Manual-A4

NEXIA TC hardware is represented in the Layout with as many as seven

separate blocks. Between these blocks can be placed virtually any of the

other available NEXIA mixing, routing, and processing blocks (component

objects). Like other component objects, NEXIA TC blocks can be placed

into the Layout either from the Processing Library

or from the Object

Toolbar. The TC – AEC Ref 8 Channel block has no control dialog of its

own. Double-clicking this block in the Layout will produce the control dialog

for the associated TC – AEC Input 8 Channel block.

AEC Ref provides the ‘reference’ signal for the associated AEC input channels. This reference is

the signal that AEC will cancel at the corresponding input. In conferencing applications, AEC Ref

blocks should typically receive 'far-end' (Receive

) and ‘program’ signals only (not microphones),

and be connected as close as possible to the output, so as to reflect any level adjustments and

signal processing applied for local sound reinforcement of those same signals. This approach

provides the most accurate reference. AEC Ref blocks should never be connected to paths

containing signal from corresponding AEC Inputs.

Each NEXIA TC comes pre-configured from the factory with a default system design. If you wish

to load your own custom designed configuration you will need to reset/initialize

the unit(s) first.

TC - Pre-AEC 8 Channel

NEXIA TC hardware is represented in the Layout with as many as seven

separate blocks. Between these blocks can be placed virtually any of the

other available NEXIA mixing, routing, and processing blocks (component

objects). Like other component objects, NEXIA TC blocks can be placed

into the Layout either from the Processing Library

or from the Object

Toolbar. To access TC – Pre-AEC 8 Channel settings, double-click over

the corresponding block in the Layout. This opens a Control Dialog Box

which provides all available settings.
