MIF fMId Frequency: 400 — 6.3 kHz)
Sets the center frequency of the Mid equalizer band.
HiGfHlah Gain:-15-+15 dB)
Sets the amount of boost or cut applied to frequencies above
6.3 kHz.
Wah
TYP (Filter Type: РЕК. LPF. HPF. BPR
Selects the type of filter response used to produce the wah
effect. Refer to page 23.
FRQ (Frequency: 40Hz — 8 kHz)
Sets the basic frequency around which the wah filter sweep
will occur — i.e. the center or cutoff frequency of the selected
filter type.
GAIN (Gain:-18-+18 dB)
This parameter is only available when the "РЕК" filter type is
selected in the "TYP" parameter. It sets the gain of the filter
peak — minus values for a notch response and plus values
for a normal peak response.
Q (Quality Factor: 0.50 —10)
When the TYP parameter, above, is set to "PEQ" or "BPF",
this parameter sets the bandwidth of the peak or passband.
When TYP is set to "LPF" or "HPP, the Q parameter controls
resonance (a peak at the filter cutoff frequency). Higher
values produce a narrower bandwidth or higher resonant
peak.
SEN (Sensitivity: 0-10)
Determines the sensitivity of the wah effect. Higher values
produce a broader frequency sweep.
CTR fController: LFO. INL INR. FVI. FV2. MID. FC1. FC2)
Selects the control mode for the wah effect. Refer to page
23.
SPD (Modulation Speed: 0.1Hz —lOHz)
Sets the speed of the internal low-frequency oscillator —
effective when the LFO control option is selected in the
"CTR" parameter, above.
LVL (Output Level: -30 — +6 dB)
Sets the output level of the CDW effect.
