AUDIO EXPANDER REAR PANEL
EX-IO expander pictured. The type and number of inputs and outputs
will vary depending on expander model
1.
Grounding pin
This pin is for grounding the chassis of the expander
2. AVB/Control Connection
Uses a standard RJ-45 connector with CAT-5, CAT-5e, CAT-6 or CAT-7 cabling.
This connection is for PoE+, 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).
3. Audio Connections
The connections 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 is shown without the
removable connector inserted.
Input connections (channels 1 or 2 on the EX-IO and channels 1-4 on the EX-IN and EX-AEC) are for
connecting analog mic or line level audio signals to the Tesira system. The connections are
balanced and can provide Phantom power if necessary by software control.
Output connections (channels 3 or 4 on the EX-IO and channels 1-4 on the EX-OUT) are for sending analog audio signals
from the Tesira system to other audio devices at either mic level or scalable line level.
