Reverb Programs; Rev 1 Hall; Rev 2 Room; Rev 3 Vocal - Yamaha SPX1000 Operation Manual

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.
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 (LFO 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.
2-CHANNEL PROGRAM (PROGRAMS 31 – 35) EQ
PARAMETERS
The EQ parameters for the 2-channel programs (programs 31
– 35) are the same as for the other programs, except that
separate EQ parameters are provided for the left and right
channels when the "EQ" mode is selected.
L LOW EQ = Left-channel Low EQ
L LOW F = Left-channel Low Frequency
L LOW G = Left-channel Low Gain
L LOW Q = Left-channel Low Bandwidth
L HI EQ = Left-channel High EQ
L HI F = Left-channel High Frequency
L HI G - Left-channel High Gain
L HI Q = Left-channel High Bandwidth
R LOW EQ = Right-channel Low EQ
R LOW F = Right-channel Low Frequency
R LOW G = Right-channel Low Gain
R LOW Q = Right-channel Low Bandwidth
R HI EQ = Right-channel High EQ
R HI F = Right-channel High Frequency
R HI G - Right-channel High Gain
R HI Q = Right-channel High Bandwidth

4. REV4 PLATE
5. REV5 ECHO ROOM
Reverberation is the warm musical "ambience" you
experience when listening to music in a hall or other properly-
designed acoustic environment. The SPX1000 offers several
different reverb effects, simulating types of reverberation you
would experience in a hall (REV 1 HALL), in a smaller room
(REV 2 ROOM), a reverb effect ideally suited to vocals (REV
3 VOCAL), the type of reverberation produced artificially by
