• Low Pass. Selectable frequency cutoff is 20Hz to 20kHz in 1Hz increments.
Rolloff is 12dB/octave. Level is fixed at 0dB.
• Notch. Center frequency range is 20Hz to 20kHz with resolution to 1Hz or
four places (whichever is larger). Bandwidth is from .05 to 5 octaves in .01
octave increments. Level is fixed at -80dB.
• PEQ (parametric equalizer). Center frequency range is 20Hz to 20kHz
with resolution to 1Hz or 4 places (whichever is larger). Bandwidth is .05
to 5 octaves in .01 octave increments. Level range is -15 to +15dB in
0.5dB increments.
Frequency. Use Frequency to select the center frequency (in Hertz) for the filter
you are configuring. Range is from 20Hz to 20kHz. Default is 1kHz.
Gain. Gain adjusts the gain value from -18 to 18dB, in .5dB steps. Default is 0dB.
Q, or Quality factor. Q, or Quality factor, selects the ratio of the center frequency
divided by the bandwidth. Q reflects an inverse relationship to the bandwidth, and
adjusts from .02:1 to 40:1 on the PSR1212.
Bandwidth. Bandwidth establishes the difference between the upper and lower
points of a filter’s audio passband.
Bypass. The Bypass box, when selected, bypasses the selected filter.
Phase. Phase generates—on the graph—the phase relationship of the graphed
frequency response.
Bypass All. Bypass All bypasses all filters.
Add Filter. Add Filter adds a filter to the graph, centered at 1kHz and 0dB.
Remove Filter. Remove Filter removes the selected filter from the graph.
Table View
Table View toggles between the Graph and the Table views of the Inputs 1-8 Filter
window. The Table view displays the selected filter settings in table format. You can
configure filters from this view as well as in the graph view.
