Biamp Tesira EX-IN
Networked 4-Channel Mic/Line Input Expander (AVB, PoE+)
The Tesira EX-IN is a networked audio expander that adds four channels of microphone or line level input to a Biamp Tesira system. It connects to the AVB media network for audio transport, configuration, and control, letting integrators place input connectivity exactly where sources live rather than routing long analog cable runs back to a central rack.
Housed in a compact half-rack chassis, the unit is powered over the network by PoE+, which simplifies installation and removes the need for a local power supply. Each input offers software-controlled gain along with switchable phantom power for condenser microphones, making it well suited to conference rooms, courtrooms, and distributed audio deployments where endpoints must sit close to the talkers.
