• Rotate the Setting knob to select the type of slope.
Parameter setting range: THRU (through), 6 dB (6 dB/oct), 12BS
(12 dB/oct BS), etc. (Refer to p. 87 for
more information.)
Notes
(1) Slope type: BS (Bessel), BW (Butterworth), LR (Linkwitz-
Riley), VQ (Variable Q)
(2) Displayed slope type differs depending on the Crossover
configuration setting. (Refer to p. 62.)
• Using the shift key, the display is moved to the Crossover
Gain setting screen if THRU is selected, and to the Cutoff
Frequency setting screen if parameters other than THRU are set.
• Pressing an Output channel selector key permits the crossover
filter to be set for that channel. The [OUT 1] indication changes to
the selected channel number indication.
