Filter Type (FLT TYPE): LPF, HPF, BPF, PEQ
Determines the response of the dynamic filter:
LPF = Low Pass Filter
HPF = High Pass Filter
BPF = Band Pass Filter
PEQ = Parametric EQ
Center Frequency (F CENTER): 32 Hz – 16 kHz
Sets the starting center frequency of the dynamic filter.
Frequency Depth (F DEPTH): 0 – 8 octaves
Determines the maximum sweep range of the dynamic filter.
Filter Gain (GAIN): -18, -12, -6, 6, 12, 18 dB (when
FLT TYPE = PEQ only)
Determines the gain of the dynamic filter when the PEQ filter
type is selected. Minus values create a notch response while
positive values create a peaking response.
10
Bandwidth (Q): LOW, HIGH
Sets the bandwidth of the dynamic filter.
Filter Shift Direction (SHIFT): UP, DOWN
Determines which direction the dynamic filter will sweep in
from the starting point.
Filter Sensitivity (SENSITIVITY): 1 – 10
Adjusts the sensitivity of the dynamic filter. Higher settings
create a greater degree of sweep for the same change in input
level (LEVEL control type).
Filter Decay (DECAY): 1 – 10
Determines the speed at which the dynamic filter will return
to the starting frequency after activation.
Low Frequency Oscillator Frequency (LF0 FRQ):
0.1 – 10.0 Hz
Sets the LFO frequency and thus the speed of dynamic filter
sweep when the LFO control type is selected.
DUAL EFFECT PROGRAM (PROGRAMS 48 – 50)
EQ PARAMETERS
The EQ parameters for the dual effect programs (programs
48 – 50) are the same as for the other programs. except that
separate EQ parameters are provided for the each effects
when the "EQ" mode is selected.
1 LOW EQ = Effect 1 Low EQ
1 LOW F = Effect 1 Low Frequency
1 LOW G = Effect 1 Low Gain
1 LOW 0 = Effect 1 Low Bandwidth
1 HI EQ = Effect 1 High EQ
1 HI F = Effect 1 High Frequency
1 HI G = Effect 7 High Gain
1 HI Q = Effect 1 High Bandwidth
2 LOW EQ = Effect 2 Low EQ
2 LOW F = Effect 2 Low Frequency
2 LOW G = Effect 2 Low Gain
2 LOW Q = Effect 2 Low Bandwidth
2 HI EQ = Effect 2 High EQ
2 HI F = Effect 2 High Frequency
2 HI G = Effect 2 High Gain
2 HI Q = Effect 2 High Bandwidth
