Extend conference audio beyond the limits of a single speakerphone and keep every participant in range. The EPOS Expansion Microphone 1000229 is designed for the EXPAND 80 speakerphone, giving IT teams a practical way to cover larger tables, longer meeting rooms, and distributed seating without replacing the core system. For collaboration spaces where voices drop off at the edge of the table, an expansion microphone helps maintain consistent pickup and clearer speech delivery. That matters in executive rooms, project war rooms, and hybrid meetings where audio quality directly affects pace and decision-making. Instead of asking people to lean in or repeat themselves, the room stays usable from more positions. This accessory fits naturally into a premium conference setup: add coverage where it is needed, preserve the clean desk aesthetic, and keep the audio chain centered on a trusted EPOS platform. For organizations standardizing on EXPAND 80, it is a focused upgrade that improves meeting-room reach without adding unnecessary complexity.
