1. Hall 1 2. Hall 2
7. Room 3 8. Room 4
These are all reverberation ("reverb" for short) effects. Reverb is the warm musical "ambience" you expe-
rience when listening to music in a hall or other natural environment.
1. REVERB TIME Range: 0.3 ... 30 sec.
Sets the amount of time it takes for the reverb sound to decay by 60 dB (virtually to silence).
2. DIFFUSION Range: 0 ... 10
Adjusts the left-right "spread" of the reverb sound. The higher the value the greater the spread.
3. INITIAL DELAY Range: 0 ... 63
The length of the initial delay before the actual reverb sound begins (in milliseconds). The higher the value the
longer the initial delay.
4. HPF CUTOFF Range: Thru, 22Hz ... 8.0kHz
The cutoff frequency of the high-pass filter applied to the reverb sound. No filter is applied when set to "Thru".
5. LPF CUTOFF Range: 1.0kHz ... 18kHz, Thru
The cutoff frequency of the low-pass filter applied to the reverb sound. No filter is applied when set to "Thru".
13. EaryRef1 14. EaryRef2
EaryRef (Early Reflections) effects are created using different groupings of "early reflections" — the first
cluster of reflections that occurs after the direct sound but before the dense reflections that are known as re-
verberation begin.
The GateRev (Gate Reverb) and RevrsGat (Reverse Gate) effects combine reverb with a selectable "gate".
1. EARLY REF TYPE (EarlyRef1 & 2)
The "S-H" and "L-H" settings select typical groupings of early reflections that would occur in a small or large
hall, respectively. "RDM" (Random) produces an irregular series of reflections that could not occur naturally.
"RVS" (Reverse) generates a series of reflections that increase in level — like the effect produced by playing a
recorded reverberation sound backwards. "PLT" (Plate) produces a typical grouping of reflections that would
occur in a plate reverb unit, and "SPR (Spring) simulates the early reflections of a spring type reverb unit.
1. GATE TYPE (Gaterev. & RevrsGat)
2. ROOM SIZE Range: 0.1 ... 7.0
Sets the separation between reflections. Higher values produce greater separation between reflections, and
therefore the effect of a bigger room.
3. DIFFUSION Range: 0 ... 10
Adjusts the left-right "spread" of the early reflection or gated reverb sound. The higher the value the greater the
spread.
4. INITIAL DELAY Range: 0 ... 63
Sets the delay time before the early reflection or gated reverb sound begins.
5. FEEDBACK LEVELRange: –63 ... 0 ... +63
Determines the amount of effect-sound feedback returned to the input of the effect stage. Higher negative or
positive values produce a more extended effect.
