The Oxford DeBuzzer
Description of Controls – Frequency Detect Section
“Auto” – Auto mode is the default tracking mode. In this mode the removal filters automatically
follow the peak frequency found in the peak profile. It is suitable for tracking a weak, slowly
wandering fundamental and operates over all three frequency bands.
“Fast” – Fast tracking mode allows the removal filters to automatically follow a quickly
wandering fundamental. This mode operates on MF and HF frequency selections only.
“Freeze” – For a fundamental that is a fixed frequency, once the auto mode has found the best
nominal frequency, you can freeze the nominal. In freeze mode, the removal filters follow the
value of the nominal frequency set by the big rotary frequency control.
“Sensitivity” – Start at a high value and back off to the point at which the hum becomes audible
again, then push it up a little to make the hum disappear. Doing this correctly ensures least
damage to the signal.
