Korg GEC5 Teacher Unit

  • Fully digital design throughout, featuring digital transfer of audio from each student station to the GEC5 Teacher Station unit with output for digital recording of any workstation in the system, and conventional analog inputs and outputs.

  • Proprietary software is included and features customizable teacher and class setups, including individual teacher preferences and class set-ups displaying student names. New upload feature allows for easy and quick class creation. (Mac and Windows only.)
