Delay Compensation
The delay compensation control adds a fixed delay to the line input and
bypass signal processing paths to keep the different version of the input pro-
cessing time aligned through the input processing.
Microphone inputs have approximately 16 msec of latency due to the AEC and
noise cancellation processing. By selecting delay compensation, 16 msec of
delay is added to the line input and bypass ungated signal types.
The option for the delay compensation is shown when the Line Input or
