EX-MOD PRODUCT DESCRIPTION
The Tesira® EX-MOD is a modular expander device that is designed for use with Tesira SERVER, SERVER-IO, and
TesiraFORTÉ AVB devices. It can be configured with up to three 4-channel input and/or output expander cards for a
maximum of 12 channels of I/O. The cards include EIC-4 (4 channels of mic/line level audio input), EEC-4 (4 channels of
mic/line level audio input with AEC (acoustic echo cancellation)), EOC-4 (4 channels of mic/line level audio output) and
EIOC-4 (2 input and 2 output of mic/line level audio). The EX-MOD expander communicates with the Tesira AVB network
for audio networking, configuration, and control.

1. Grounding pin
This pin is for grounding the chassis of the expander
2. AC Power inlet
3. AVB/Control Connection
Uses a standard RJ-45 connector with CAT-5, CAT-5e, CAT-6 or CAT-7 cabling.
This connection is for sending and receiving AVB audio signals as well as sending and receiving data between the
expander device and the Tesira system. An expander will not operate if it is not on a network that includes a Server-Class
Tesira device.
The maximum distance between any unit and an Ethernet switch is 328 feet (100 meters).
4. Audio Slots
These slots may be optionally factory loaded or field loaded with EX-MOD audio cards. The audio connection on the cards
are electrically balanced and are configured for use with shielded-twisted-pair wiring. The wires are to be terminated in the
three-pin removable connectors according to the wiring diagram shown on the unit. The wiring diagram is also displayed
on the connectors themselves. The connectors may then be inserted into the mating connectors on the expander. In the
illustration above, channel one on the card in Slot 1 is shown without the removable connector inserted (far right
connector).
EIC-4 Card
The Tesira EIC-4 is an expander card with four analog input channels for use with the Tesira EX-MOD device. The EIC-4
is one of three optional cards that can be mounted in Tesira EX-MOD. Each EIC-4 provides four channels of mic/line level
audio input. The inputs are electrically balanced and provided on plug-in barrier strip connectors. Software control of each
input includes gain with clip indicator, +48V phantom power, mute, level and signal invert.
EEC-4 Card
The Tesira EEC-4 expander card is an optional card that can be installed in the Tesira EX-MOD. Each EEC-4 provides
four channels of mic or line level audio input with AEC (Acoustic Echo Cancellation). The inputs are electrically balanced
and provided on plug-in barrier strip connectors. Software control of each input includes gain with clip indicator, +48V
phantom power, mute, level, and signal invert.
EOC-4 Card
The Tesira EOC-4 is an expander card with four analog output channels for use with the Tesira EX-MOD device. The
EOC-4 is one of three optional cards that can be mounted in Tesira EX-MOD. Each EOC-4 provides four channels of line
level audio output. The outputs are electrically balanced and provided on plug-in barrier strip connectors. Software control
of each output includes mute, level, signal invert and full-scale output reference.
EIOC-4 Card
The Tesira EIOC-4 is an expander card with two input and two output channels for use with the Tesira EX-MOD device.
The EIOC-4 is one of three optional cards that can be mounted in Tesira EX-MOD. Each EIOC-4 provides two channels of
mic/line audio input and two channels of line level audio output. The inputs and outputs are electrically balanced and
provided on plug-in barrier strip connectors. Software control of each input includes gain with clip indicator, +48V phantom
power, mute, level and signal invert. Software control of each output includes mute, level, signal invert and full-scale
output reference.
