Wideband Bridging Conference Interface

The SPNCWB from Lectrosonics is a wideband conference interface that makes tele-presence and multi-site bridging simple and effective in any conference room, with full bandwidth audio frequency response and a unique Quad-reference AEC (Audio Echo Canceller).

Each conference connection includes a dedicated AEC for fast and reliable echo cancellation. The AEC converges very fast and will remain converged during double-talk and any signal type, including sine waves, enabled by an advanced DSP algorithm. Cancellation depth increases even with brief signal peaks from the far ends.

SPNCWB features include:

  • Quad-reference wideband acoustic echo canceller supporting 3-way bridging
  • Two maximum speed grade, 4th generation SHARC processors
  • Dual codec interfaces
  • TCP/IP Ethernet addressable
  • Fully integrated with ASPEN digital matrix
  • Adaptive proportional gain automatic mixing at the matrix cross-points
  • Third octave noise filter on each channel
  • Sigma-Delta class-D audio power amplifiers
