30 SPX2000—Owner’s Manual
Stereo Reverb (PRESET bank)
These are stereo reverbs; they allow two-channel input.
Each aspect of the sound is controlled by the following effect parame-
ters.
Early reflections: INI.DLY
Reverberation: REV TIME, HI.RATIO, LO.RATIO, DIFF., DENSITY
Overall effect sound: REV TYPE, E/R BAL.
Filter/equalizer: HPF, LPF
Output level: OUT LVL, MIX BAL.

Parameter name Range Explanation
REV TYPE Hall, Room, Stage, Plate
The pattern of reverb; this determines the basic character of the effect. The characteristics of the
reverberation will depend on the type you select here.
REV TIME 0.3—99.0 s
Reverb time. This is expressed as the time over which reverberation at 1 kHz will decay by 60 dB.
HI.RATIO 0.1—1.0
Reverb time for the high-frequency range or low-frequency range, expressed as a proportion of
REV TIME. If this value is 0.1 the time will be 1/10th the REV TIME; if it is 1.0 the time will be the
same as the REV TIME. You can adjust these values to simulate the absorptiveness of the walls or
ceiling. HI.RATIO is the decay of the high-frequency range, and LO.RATIO is the decay of the low-
frequency range.
LO.RATIO 0.1—2.4
INI.DLY 0.0—100.0 ms
Delay of the early reflections relative to the original sound. This also affects the delay until the
reverberation is heard.
DIFF. 0—10
Diffusion of the sound to left and right. Increasing this value will make the reverberation more
spaciousness.
DENSITY 0—100%
Density of the reverberation. Increasing this value will make the reverberation smoother. You can
create unique effects by lowering this value.
Parameter name Range Explanation
MIX BAL. 0—100%
Balance between the original sound and effect sound. At a setting of 0% only the original sound
will be output; at a setting of 100% only the effect sound will be output.
OUT LVL 0—100%
Output level after the original sound and effect sound have been mixed. Decrease this value if you
want to lower the output. At a setting of 0% there will be no output.
E/R BAL. 0—100%
Balance of the early reflections and subsequent reverberation. At a setting of 100% only the early
reflections will be output; at a setting of 0% only the reverberation will be output.
HPF Thru, 21.2 Hz—8.00 kHz
A filter that cuts the low-frequency portion of the effect. Frequency components lower than the
frequency specified here will be cut. With a setting of Thru this filter will do nothing. This filter
does not affect the original sound.
LPF 50.0 Hz—16.0 kHz, Thru
A filter that cuts the high-frequency portion of the effect. Frequency components above the fre-
quency specified here will be cut. With a setting of Thru this filter will do nothing. This filter does
not affect the original sound.
