Biamp Tesira EIC-4 4-Channel Expander Input Card

The Biamp Tesira EIC-4 is a 4-channel expander input card for the Tesira EX-MOD chassis, one of three optional cards that mount in EX-MOD alongside the EOC-4 output and EIOC-4 combo cards. Each EIC-4 adds 4 channels of balanced mic or line level input on plug-in barrier strip connectors, with 0-66 dB of gain in 6 dB steps, a clip indicator, and switchable +48V phantom power.

Every input is fully configurable in software: gain, mute, level, and signal invert for reverse polarity, plus a -100 dB to +12 dB fader range. A/D conversion runs 24-bit at 48kHz. It carries Biamp's 5-year warranty and is a direct sibling to the already-stocked Tesira SIC-4 and SEC-4 server cards, built for EX-MOD expansion rather than the Tesira SERVER chassis itself.
