12. AUTOMATIC CLIPGUARD (ACG) FUNCTION
It is a function that automatically control input sensitivity to an appropriate value when the broadcast is distorted
in the presence of an excessive input signal.
For example, the ACG function prevents the broadcast from being made with its sound distorted even if a line
level signal is erroneously applied to the MONO IN input set to "MIC."
The ACG function operates on each channel with the input sensitivity selector switch placed in "MIC" or
"PHANTOM" position.
Notes
• If the ACG function works, something is wrong with connection. Make cable connection correctly after an
announcement is complete.
• Distorted sound is output from the unit for several seconds in order to detect distortion, however, this is not a
failure.
