SPNCWB

• 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

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).
