To utilize the feedback processing, you must enable the feedback processing on the EQ page for the desired

inputs and select the sound reinforcement signal processing path Recall that the input processing has

different types of audio processing available for the input signals. The sound reinforcement signal path for

the C-series products is shown in the following figure.

You can select the sound reinforcement signal path at the matrix crosspoint by selecting the Snd

Reinforcement option of the gated/automixed, as shown in the following figure. Selecting the Snd

Reinforcement option ensures that the proper input processing path is selected for routing microphones to

loudspeakers.

Note: Using the Feedback Processing

To use the feedback processing, enable the processing from the EQ page and

select the sound reinforcement version of input processing path in the matrix.

Enabling Acoustic Echo Cancellation (AEC)

The AEC is enabled/disabled by toggling the AEC button. The AEC control displays the mode of the

acoustic echo canceller with Xmit indicating the system is transmitting audio to the remote site and Recv

indicating the system is receiving audio from the remote site and is heard in the local room.
