Four built-in mic inputs, enterprise-telephone interface, speaker amplifier for standalone applications, enhanced management features and simplified configuration make 840T the perfect expandable solution for virtually any venue or application.

Key Features

  • Full-bandwidth Acoustical Echo Cancellation (AEC) keeps audio clear of reverberations
  • Improved duplex performance to create the most natural interaction
  • Next-generation noise cancellation with adaptive modeling matches rooms ambient noise
  • Increased resolution on Microphone Preamp stage provides fine tuning 0-56 dB in 7 dB increments
  • D.A.R.E (Dynamic Automatic Resonance Elimination) completely controls feedback
  • Next-generation Distributed Echo Cancellation on every mic input
  • First-mic priority delivers clear audio to the far end
  • 20 Hz-22 kHz bandwidth for full-range audio response
  • Automatic Gain and Level controls maintain balanced and consistent audio clarity
  • Scalable by linking multiple units for extensive mic coverage and up to 16 phone lines
  • Ten mic gating groups (four internal & six global) allow separation of mics into individual mixer gating groups for greater configuration flexibility
  • No space required between rack mounted units
  • 32 presets can be executed on-the-fly without disturbing other ongoing preset operations
  • SNMP and HTML remote management give IT professionals flexible options for access
  • Event scheduler and diagnostic console for automation of updates and simplified maintenance
