Type
Use the Type list to select from the following input filters: All Pass, High Pass, Low
Pass, Notch, and PEQ. G-Ware features other filters which are configured in the
Processing section of the software (see page 49).
• 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 -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 XAP 400.
