Symetrix AEC MODULE AEC-2 Dual Core AEC Coprocessor Output Card for Radius NX 4x4 or Radius NX 12x8 - 16/12 Channels

80-0153 - Overview

• Features:

  • Superior and consistent single-talk echo reduction of 60dB in any acoustic environment.
  • Proprietary robust and effective double talk detector.
  • Echo reduction of 20dB or more during double-talk periods.
  • Instant full convergence to 60dB echo reduction in 100 milliseconds, or less. Rate of adaptation is fast enough to allow excellent performance even with moving microphones and dynamic gain changes.
  • Supports multiple microphones (up to 4 inputs per card/module, 16 per unit, fully loaded)
  • Supports routing any audio through the AEC algorithm
  • Independent Ref input for every channel of AEC, currently up to 6 reference inputs with a max of 6 AEC inputs
  • Low algorithm processing latency, 11ms
  • Noise cancellation algorithm providing up to 20 dB background noise reduction. Noise reduction level is user adjustable.
  • The algorithm is effective against moderate nonlinearities in the acoustic response model and Reference signals.
  • Consistent performance in all acoustic environments, from a small room with a reverberation time of less than 100ms to a large conference hall with reverberation time of 1.5 seconds or more.
  • Suitable for any application that requires echo and/or noise cancellation, including speakerphones, audio and video conferencing, desktop conferencing, voice over IP, Internet phones, and many others.
  • Fully configurable. System designers have complete control over system switches and algorithm parameters, including the ability to enable/disable and set the target level of individual channels in any functional block.
  • Fully compliant with the G.167 standard.
