Ducking Threshold
This modification adjusts the threshold for activating the ducking circuit.
The ducking threshold can be raised or lowered by first removing resistor R333, and then placing a resistor (R) at jumper X303.
To lower the ducking threshold, use a resistor value (R) less than 2k ohms. To raise the ducking threshold, use a resistor value
(R) greater then 2k ohms.
