11 — Diffusion 2 Range: 00 to 99
This parameter, similar to and in series with Diffusion 1, performs the same way but controls
lower frequency ranges. Recommended setting is approximately 50.
12 — Decay Definition Range: 00 to 99
Controls the rate of echo density build up in the reverb decay. If set too high, the echo density
will build at a rate that exceeds the decay rate. A general rule of thumb: Definition should not
exceed the Decay Rate. We recommend settings between 25 and 50.
13 — Slapback Range: 0 to 500 ms
Controls the delay time of an internal dry stereo signal to create a slapback. In general, the
slapback is greater or equal to the Hold Time (parameter 04) to achieve a reverse effect.
14 — Slapback Level Range: 00 to 99
Adjusts the volume of the slapback (internal dry) signal. A value of 00 would eliminate any
audible slapback.
15 — Early Reflections 1
16 — Early Reflections 2
17 — Early Reflections 3
18 — Early Reflections 4 Ranges: -99 to +99
These parameters control four early reflection levels. Setting these levels to lower values will
produce a wetter sound.
19 — Left/Right Balance Range: -99 to +99
Controls the left/right stereo balance of the gated reverb signal. A setting of -99 would offer hard
left, whereas a setting of +99 would offer hard right. A setting of +00 would place the reverb in
the center of the stereo spectrum.
