AGC Hold Time
Sets the hold time for slow AGC.
AGC Noise Pulse Reject
When this parameter is ON, the DSP will suppress large, periodic noise bursts typical of electrical
appliance turn on/off, etc., preventing saturation of AGC and consequent long recovery time.
However, when continuous pulse noise is present, the noise blanker (NB) will be much more
effective. Use the lowest effective NB setting to avoid intermodulation.
AGC Slope
Sets the slope of AGC attack. A value that is too small will allow excessive overshoot on strong
signals; a value that is too large will make attack sound harsh.
AGC Threshold
Sets the signal level where AGC action begins. A lower threshold keeps the audio level fairly constant
over a wide signal amplitude range. A higher threshold imparts more "presence" to signals by
allowing for greater variance.
AutoRef Averaging
When <DISPLAY> <REF LVL> is set to AUTO, this parameter controls the amount of baseline noise
averaging.
AutoRef Debounce
When <DISPLAY> <REF LVL> is set to AUTO, this parameter controls the amount of signal
amplitude change required to retrigger automatic reference determination.
AutoRef Offset
When <DISPLAY> <REF LVL> is set to AUTO, this parameter allows fine-tuning of the amount of
