Reference
Diffusion, Predelay, Reverb Level, and Rolloff
DIFF (Diffusion) 0 - 99
DIFF controls the degree to which initial echo density increases over time. High settings of
DIFF result in high initial buildup of echo density; low settings cause low initial buildup. Echo
density is also affected by SIZE; smaller spaces will sound denser. To enhance percussion, use
high settings of DIFF. For clearer, more natural vocals, mixes, and music, use low or moderate
settings.
PDLY (Predelay) 0 - 1000ms
PDLY adds an additional delay between the input signal and the onset of reverberation. This
control may be useful in a sound reinforcement situation, or for ambience effects. Both DDLY
and PDLY have 4-sample (approximately 0.1msec) resolution.
RLVL (Reverb Level)
RLVL sets the amount of reverberation in the processed signal. It is normally FULL, but may
be reduced for effects where the pre-echoes should dominate.
ROLL (High Frequency Rolloff) 0.1 - 26.5kHz, Flat
ROLL sets the frequency above which a 6 dB/octave low-pass filter attenuates the processed
signal. It attenuates both pre-echoes and reverberant sound. High frequencies are often rolled
off with this parameter, resulting in more natural sounding reverberation.
Rich Plate Delays and Feedback Pre-Echoes
Rich Plate provides control over three stereo delay pairs. All three are summed with the output
of the reverberator. Many, many different echo combinations are possible.
DLY1 (Delay 1), DLY2 (Delay 2) 0 - 2000ms
DLY1 and DLY2 are recirculating delay lines to the left and right channel inputs. The path of
either is picked off after the diffusor with the amount of recirculation defined by the adjustment
of FBK1 (for DLY1) and FBK2 (for DLY2). DLY1 and DLY2 are the only delays which effectively
feed back (recirculate) into the reverberator.
