SPRD (Spread) SPRD works together with SHAP to control the duration of the initial ambience
created by the 300. Low SPRD settings result in a rapid onset of reverberation
at the beginning of the envelope, with little or no sustain. Higher settings spread
out both the buildup and sustain.

BASS (Bass Multiply)
BASS sets the reverb time for low-frequency signals, as a multiplier of the RTIM
parameter. For example, if BASS is set to 2X, and RTIM is set to two seconds,
the low frequency reverb time will be four seconds. For a natural-sounding hall
ambience, we recommend values of 1.5X or less.
DIFF (Diffusion)
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.
RAND (Randomization)
RAND sets the distance in time that the early reflections will move.
XOVR (Bass Crossover)
XOVR sets the frequency at which the transition from RTIM to BASS takes place.
XOVR should be set at least two octaves higher than the low frequency you want
to boost. For example, to boost a signal at 100 Hz, set XOVR to 400 Hz (This
setting works well for classical music). XOVR works best around 400 for boosting
low frequencies, and around 1.5 kHz for cutting low frequencies.
LINK When LINK is set, the reverb time and spread values scale linearly as the SIZE
control is varied. For some special effects, RTIM and SPRD can be unlinked.
