SPX2000—Owner’s Manual 29
Reverb
Reverb (CLASSIC bank)
These reverbs are based on effects of earlier models in the SPX series.
There is no distinction between early reflections and subsequent
reverberation.
Each aspect of the sound is controlled by the following effect parame-
ters.
Reverberation: REV TIME. HI.RATIO, DELAY
Filter/equalizer: HPF, LPF
Output level: OUT LVL, MIX BAL.
Parameter details
■Basic parameters
Effect list
The following table show the default parameter values for the effects belonging to the Reverb type (CLASSIC bank).
Parameter name Range Explanation
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, 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.
DELAY 0.0—500.0 ms
Delay of the reverberation relative to the original sound.
HPF THRU, 32 Hz—1.0 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 1.0—11 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.
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.
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.
