The Tesira EIOC-4 is an expander card with 2 input and 2 output channels for use with 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 2 channels of mic/line audio input and 2 channels of mic/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; whereas for output includes mute, level, signal invert, and full-scale output reference. The modular card shall provide 2 balanced inputs and 2 balanced outputs on plug-in barrier strip connections. Software configuration and control for each input shall include gain with clip indication, phantom power on/off, mute, level, and signal invert. Analog-to Digital and Digital-to-Analog conversion shall be 24-bit with a sampling rate of 48kHz.
