TC Hardware
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
TC - AEC Input 8 Channel (or TC - AEC Ref 8
Channel ) blocks, and the optional TC - Pre-AEC 8 Channel 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
TC - Input 2 Channel block in
the Layout.
Telephone Set / Line: These two parallel RJ11 jacks provide industry-standard Tip & Ring
connections for an analog telephone line and a desk-set station. Settings for this interface are
accessed by double-clicking the individual
Telephone Interface blocks 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
TC - Output 4 Channel
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,
NexLink 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
System
Network Considerations ). 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.
