2.2 AGC Operation Guide
Automatic gain control (AGC) provide a controlled signal amplitude at its output, despite variation
of the amplitude in the input signal. By disabling AGC function, the hiss can be eliminated when
the camera is recording during quite moments.
When recording under stereo mode and set the AGC switch to off, a 20kHz sine wave will be
sent from left channel to the camera to turn off the AGC function. The 20kHz sine wave can be
easily filtered out, and the left channel can still be used for normal recording.
When recording under mono mode, you could set the M/S switch to S and recording only on the
right channel. Leaving the left channel unused, so the 20kHz sine wave will not be recorded into
the audio file.
Suggestion:
(a) When turn the volume of each channel to the maximum but the recording sound is still
low or not clear, you could turn off the AGC.
(b) When turn the volume of each channel to the minimum but the recording sound is still
high, you could turn off the AGC.
(c) When the background noise affect the recording, please turn off the AGC.
(d) If you don’t want the 20KHz sine wave to be recorded into the audio file, please turn on
the AGC.
Please do a test recording and play back the audio to see if it is acceptable.
