Next, the signal is 200Hz Highpass filtered, to remove any low frequency noises that may remain

after processing, and 3200Hz Lowpass filtered to remove high frequency hiss.

Finally, a 10dB AGC is applied to correct for near party / far party talkers, and to provide a good

output level for recording.

2CH MODE:

Notice that in 2CH MODE, both the LEFT (PRI) and RIGHT (REF) inputs get fed into the processor.

The LEFT (PRI) input is the signal from which interfering audio is to be removed, usually originating
