Zitat aus Beachtek dxa5d ManualUsing the AGC DSBL Feature
This switch is a means to disable the wild swings of the Auto Gain Control in the camera. It activates
an inaudible tone of 20 kHz to the left channel (when set to STEREO operation) that prevents the Auto
Gain Control from increasing the gain to its maximum level. This reduces the hiss that normally occurs
when the camera is recording audio during quiet moments. The tone is recorded by the camera but can
be easily filtered out if necessary. You can still use the left channel for recording normal audio at the
same time as the AGC DSBL feature is active.
You may also want to record audio only on the right channel and leave the left channel unused for the
AGC control signal if this tone presents a problem down the line. In this case, you should set the M/S
switch to S for stereo to keep the AGC signal separated from the recorded signal. Again, it is important
that you do a test recording and play back the audio to see if it is acceptable.
The AGC DSBL feature will lower the gain on the camera, which will require a sensitive microphone for
best results.
