Q 16 to 128

Selects the Q of the selected notch filter.

4.7 Crossover

The Crossover is used to divide the input signal into several frequency bands. This allows the user to drive the speaker in its optimum frequency range and send each output separately for more efficient use of amplifier power. The DriveRack 260 Crossover can be configured as a 2x2, 3, 4, 5, or 6 (stereo configurations) or 1x1, 2, 3, 4, 5 or 6 (mono configurations). Appendix A.5 illustrates each of the available crossovers. The High-Pass or Low-Pass filter being edited is indicated by the highlighted edge in the graphical display.

Frequency

Adjusts the frequency of the Low Pass or High Pass filter from 20Hz to 20KHz.

Type

•BS (Bessel) with a slope of 6, 12, 18, or 24 dB/Octave.

•BW (Butterworth ) with a slope of 6, 12, 18, or 24 dB/Octave.

•LR (Linkwitz-Riley) with a slope of 12, 24, 36, or 48 dB/Octave.

Gain

Sets the level of the selected output(s). Range is from -Infinity to +20dB.

4.8 Post-CROSSOVER PEQ
