The HIGH and LOW PASS FILTER controls are accessed via the “Parametric and FBX Filters”
menu selection (option #3). Pressing the down arrow key repeatedly (while in the LIST mode, or
under “TYPE” in CURVE mode) through all 12 filters ultimately shows the HIGH and LOW PASS
FILTER menu.
These are the high- and low-end roll-off filters that are used to custom-tailor the low- and high-end
frequency response. A “high pass filter” allows frequencies higher than a set value to pass; in
other words, it filters out low frequencies, and the opposite happens with a “low pass filter.” The
HIGH PASS FILTER can be used to suppress phenomena such as low-frequency rumble, while
the LOW PASS FILTER can be used for attenuating high-frequency hiss or for band limiting the
POWER-Q’s output signal for telecommunications.
This screen allows setting of the high and low pass filter points. The HIGH PASS FILTER can be
inserted starting at any frequency up to 3,000 Hz. The LOW PASS FILTER can be inserted from
1,000 to 20,000 Hz.
Note that turning the data wheel to the extreme low range of the HPF and the extreme high range
of the LPF turns the filters off.
