SETTING THE FILTER TRACKING CONTROL
The FILTER TRACKING control adjusts the relationship
between the sensitivity of the Dynamic Filter and the Expander.
Once the THRESHOLD control is set for proper operation of the
downward expander increase the FILTER TRACKING control
until the desired dynamic filter operation is achieved. Setting
this control to high will cause the filter to not fully open when
high frequency signals are present. Setting this control to low
will not provide any high frequency noise reduction. The Filter
Tracking adjusts the tracking for both channels.
Once the filter is set correctly the dynamic filter will provide high frequency noise
reduction at all input signal levels. For example; if a high level input signal is present at
the input that contains low and mid frequency information but little or no high
frequency information the filter bandwidth will close to a point just above the highest
input frequency. The instant the input signal contains a high frequency audio signal
the bandwidth of the filter will open so as to allow the highs to pass unaltered. Since
the ear cannot detect a low level signal in the presence of a higher level signal in the
same frequency band the input signal will mask the audibility of the high frequency
noise. As the high frequency information in the input signal decays the filter will close
to reduce the audible level of the background noise. When set properly, the Decimator
should virtually eliminate all background noise and should operate with total
transparency.
