Setting The Filter Tracking Control; Saving Your Settings; Hum Extractor +Decimator G™ Specifications - iSP Technologies HUM EXTRACTOR +DECIMATOR G Owner's Manual

SETTING THE FILTER TRACKING CONTROL

The FILTER TRACKING control adjusts the relationship between the sensitivity of the Dynamic
Filter and the Downward Expander. Once the THRESHOLD control is set for proper operation
of the downward expander the FILTER TRACKING is adjusted in relation to the setting of the
downward expander. Push the FILTER TRACKING button in, this keeps the setting of the
DECIMATOR EXPANDER and now allows setting the operation of the Dynamic Filter. Increase
the DECIMATOR THRESHOLD control (with the FILTER TRACKING button IN) 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 cutting the amount of highs in the signal.
Setting this control to low will not provide any high frequency noise reduction. Once the FILTER
TRACKING is set, switch the FILTER TRACKING button to the out position. This now allows
simultaneous adjustment of the threshold of both the expander and the dynamic filter and will
maintain the tracking relationship for these two noise reduction operations.

SAVING YOUR SETTINGS

The HUM EXTRACTOR +DECIAMATOR G will automatically save the settings every time any
adjustment is made. This allows the unit to recall your HUM EXTRACTOR threshold settings
DECIMATOR threshold settings and the FILTER TRACKING settings. This allows instant recall
on power up and the settings will be retained until the next adjustment is made. NOTE: switch
position settings and INPUT LEVEL are not stored which means switch settings and INPUT
LEVEL will be based on the current position of the switches and the INPUT LEVEL control.
Adjustments can be easily made if playing in a new venue with higher or lower levels of HUM
and or noise. Once the filter tracking is set to your preference simply adjusting the
DECIMATOR threshold will adjust both the dynamic filter threshold and the low level downward
expander threshold. The offset between the dynamic filter threshold and downward expander
threshold will be maintained until the FILTER TRACKING button is switched in and the
DECIMATOR threshold control is adjusted to change the saved FILTER TRACKING setting.
