Acoustic Echo Cancellation for AHM-64

The Acoustic Echo Cancellation (AEC) module for AHM-64 provides 12 channels of AEC and is designed for teleconferencing and videoconferencing scenarios. 

The AEC processors are assigned using channel inserts in the AHM-64. One insert sits in the far-end Input channel, and the other in the near-end Input channel.

A Sound Reinforcement output is also provided for cases where local voice reinforcement is required.
