AEC Inputs:
These eight plug-in barrier strip connectors provide balanced input for microphone
or line level signals, and include selectable acoustic echo cancellation and background noise
reduction. For unbalanced input, wire high to (+) and ground to both ( ) & (-). Settings for these
inputs are accessed by double-clicking the
) blocks, and the optional
block, in the Layout.
Mic/Line Inputs:
These two plug-in barrier strip connectors provide balanced input for
microphone or line level signals. For unbalanced input, wire high to (+) and ground to both ( ) &
(-). Settings for these inputs are accessed by double-clicking the
the Layout.
Codec Input:
This plug-in barrier strip connector provides a balanced input for line-level audio
signals from a codec. For unbalanced input, wire high to (+) and ground to both ( ) & (-). Settings
for this input are accessed by double-clicking the
block in the Layout.
Codec Output:
This plug-in barrier strip connector provides a balanced output for line-level audio
signals to a codec. For unbalanced input, wire high to (+) and ground to both ( ) & (-). Settings
for this input are accessed by double-clicking the
block in the Layout.
Outputs:
These four plug-in barrier strip connectors provide balanced output of microphone or
line level signals. For unbalanced output, wire high to (+) and ground to ( ), leaving (-) un-
connected. Settings for these outputs are accessed by double-clicking the
block in the Layout.
NexLink:
These two RJ45 jacks provide the NexLink Tx (transmit) and Rx (receive) connections.
Up to four NEXIA devices may be linked together to share digital audio signals. Tx on one NEXIA
device is connected to RX on the next device. NexLink utilizes straight through shielded CAT5
cabling, with a maximum recommended length of 5 meters per cable. When multiple NEXIA
devices are placed in the Layout,
blocks allow routing of digital audio between linked
devices.
Ethernet:
All NEXIA devices use Ethernet, both for system programming and control.
Programming is accomplished using the NEXIA software provided with each unit. NEXIA software
is for PC computers, with Windows® XP Professiona/Vista operating system required. The PC
computer must have a network card installed, which supports 10/100BaseT Ethernet. A
10/100BaseT Ethernet switch (not hub) is required when networking multiple units (see
). Ethernet utilizes standard CAT5 cabling, which has a specified
maximum length of 100 meters. However, Ethernet switches which provide fiber-optic interface
can be used to extend the physical distance between units within a network.
Serial Control Port:
After initial programming and configuration, NEXIA systems may be
communications from third-party control systems such as AMX®
or Crestron®, using the Serial Control Port. Also, external devices may be controlled via the
Serial Control Port, by utilizing
blocks within the NEXIA system design.
