Description
The SPNCWB wideband conference interface makes telepresence and multi-site bridging simple and effective in any conference room, with full bandwidth audio frequency response and a unique Quad-reference AEC. Each conference connection includes a dedicated AEC for fast and reliable echo cancellation:
- Telephone line (POTS)
- Codec 1
- Codec 2
The fourth AEC is assignable to any final mix in the matrix for purposes such as noise cancellation (when fed a signal from a sampling microphone). 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.
Key Features:
- 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 Crosspoints
- Third Octave Noise Filter on each channel
- Sigma-delta class-D audio power amplifiers
