Biamp 901.0314 Tesira EIOC-4

Product Overview

The Biamp Tesira EIOC-4 is a combination expander card offering two mic/line inputs and two line-level outputs for the Tesira EX-MOD modular expander. It is the card integrators choose for a remote zone that needs both local sources and local outputs without dedicating a full input or output card to each. This Tesira expander I/O card connects back to the DSP over the AVB network, keeping input and output capability close to where audio is captured and played. The EIOC-4 is one of several cards that can populate an EX-MOD chassis.

Product Description

Each EIOC-4 provides two channels of balanced mic or line level audio input and two channels of balanced line level audio output on plug-in barrier strip connectors, designed exclusively for the Tesira EX-MOD expander. The EX-MOD holds up to three cards in any combination for a maximum of 12 channels and communicates with the Tesira AVB network for audio, configuration, and control. The EIOC-4 is efficient for AV system integration projects in smaller rooms or satellite zones that need a couple of microphone inputs and a pair of outputs to local loudspeakers or a display, rather than four of one type. Software control of each input includes gain with clip indicator, +48V phantom power, mute, level, and signal invert; each output offers mute, level, signal invert, and a full-scale output reference. Conversion is 24-bit at a 48 kHz sampling rate. The card carries Biamp's 5-year warranty. Pair it with the Tesira EIC-4 input card and Tesira EEC-4 AEC card for the EX-MOD, or browse the full Biamp collection.

Key Features

• Two Inputs and Two Outputs — The card provides two balanced mic/line inputs and two balanced line-level outputs on plug-in barrier strip connectors.
• Built for EX-MOD — The EIOC-4 is designed exclusively for the Tesira EX-MOD expander and can be combined with other EX-MOD cards.
• Local I/O in Remote Zones — The card keeps both source inputs and output feeds local, networked back to the DSP over Tesira AVB.
• Full Input Control — Each input offers gain with clip indicator, +48V phantom power, mute, level, and signal invert.
• Flexible Output Control — Each output offers mute, level, signal invert, and a selectable full-scale output reference for gain staging.
• 24-bit / 48 kHz Conversion — Analog-to-digital and digital-to-analog conversion is 24-bit at a 48 kHz sampling rate.
• 5-Year Warranty — The EIOC-4 is covered by Biamp Systems' 5-year warranty.

Frequently Asked Questions

Which device accepts the EIOC-4?
The EIOC-4 is designed exclusively for the Tesira EX-MOD expander, which holds up to three cards for a maximum of 12 channels.

How many inputs and outputs does it provide?
It provides two mic/line inputs and two line-level outputs, all balanced.

How does the EX-MOD connect to the Tesira system?
The EX-MOD communicates with the Tesira AVB network for audio, configuration, and control.

When should I choose the EIOC-4 over separate input and output cards?
Choose it for smaller zones that need a couple of inputs and a couple of outputs, rather than four of a single type.

Does it supply phantom power?
Yes. Each input provides switchable +48 VDC phantom power at 7 mA for condenser microphones.

Can output levels be adjusted for gain staging?
Yes. Each output offers a selectable full-scale output reference along with mute, level, and signal invert.

What warranty applies?
Biamp covers the EIOC-4 with a 5-year warranty.
