External Load Resistance is used to calculate and display AF power. Power is
calculated using the voltage measured at the AUDIO IN connections and the
resistance value you enter into this field.
Operating Considerations
This field is not displayed when the Audio In Lo field is set to 600 To Hi; the
load resistance is internally fixed to 600 ohms.
