Type
Use the Type list to select from the following input filters: All Pass, High Pass, Low Pass, Notch, and PEQ.
•All Pass. Frequency range is 20Hz to 20kHz with resolution to 1Hz or four places (whichever is larger).
•High Pass. Selectable frequency cutoff is 20Hz to 20kHz, in 1Hz increments. Rolloff is 12dB/octave. Level is fixed at 0dB.
•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
•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
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
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 XAP 400.
