Chapter 8—Insert Effect Parameters
To access the Parameters described on this page (unless otherwise noted):
Press Effects, turn the Parameter knob to select Insert Effect, and press Enter. Turn the Parameter
knob to select the parameter, and use the Value knob to change the parameter's Setting.

Speed Control Normal or Toggle Allows you to select a modulator and define what type of modulation you
want to use to affect the rotor speed. The two modulation modes are:
• Normal — The modulation source continuously switches between the
Speed slow setting and fast setting, based on the mod source position
and/or movement. Try this setting with a Mod Wheel — you’ll hear the
rotary speaker change speed based on the position of the wheel (and the
speed settings).
• Toggle — The modulation source toggles the rotor speed between the
Speed slow setting and fast setting. Every time the modulation source
moves from zero in a positive direction, the rotating speaker effect
changes speeds from slow to fast or fast to slow. Try this setting with a
Sustain pedal.
With both types of modulation, the rotary speaker always takes the
Inertia time to get to the Rotor Speed Slow and Fast settings.

Parameter Range Description
Pre HP Fc 10Hz to 1.50kHz Controls the boost or cut of the high pass filter frequency applied to the
input signal.
EQ Input Off, -49.5dB to +24dB This parameter allows you to adjust the input level before the EQs to
eliminate the possibility of clipping boosted signals.
Mid 1 Fc 10Hz to 20.0kHz Sets the center of the mid-frequency parametric. Higher values have a
brighter sound.
Mid 1 Q 1.0 to 40.0 This parameter is a bandwidth control that determines the width of the
resonant peak at the center frequency band. This parameter is equal to the
cutoff frequency divided by the bandwidth. By raising the value, you can
produce a narrower bandwidth.
Mid 1 Gain Off, -49.5dB to +24dB Sets the amount of boost or cut applied to this mid frequency shelf.
Mid 2 Fc 10Hz to 20.0kHz Identical to the Mid 1 Fc parameter, and is used to control different
bandwidths within the mid range.
Mid 2 Q 1.0 to 40.0 Identical to the Mid 1 Q parameter, and is used to control different
bandwidths within the mid range.
Mid 2 Gain Off, -49.5dB to +24dB Identical to the Mid 1 Gain parameter, and is used to control different
bandwidths within the mid range.
Mid 3 Fc 10Hz to 20.0kHz Identical to the Mid 1 Fc parameter, and is used to control different
bandwidths within the mid range.
Mid 3 Q 1.0 to 40.0 Identical to the Mid 1 Q parameter, and is used to control different
bandwidths within the mid range.
Mid 3 Gain Off, -49.5dB to +24dB Identical to the Mid 1 Gain parameter, and is used to control different
bandwidths within the mid range.
EQ Output Off, -49.5dB to +24dB Since speaker cabinets are “lossy,” output gain is required to compensate
losses in perceived volume. Setting this gain too high will cause clipping
of the output signal.
HPF Cutoff 10Hz to 20.0kHz Filters out the low frequencies. The higher the value, the less low
frequencies pass through. This parameter is used to increase brightness.
