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.
TDCY (Treble Decay)
TDCY sets the frequency above which sounds decay at a progressively faster rate. It filters all
the sound except the pre-echoes. When set relatively low, it gives a darker tone to the
reverberation, simulating the effect of air absorption in a real hall. TDCY also helps keep the
ambience generated by the effect from muddying the direct sound.
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.
RAND (Randomization) Off, 0 - 98%, Up Full
RAND sets the rate of randomization of the reverb tail.
Diffusion and Predelay
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 adjusts an additional time delay between the input of signal and the onset of reverbera-
tion. The control is not intended to mimic the time delays in natural spaces. In real rooms the
build-up of reverberation is gradual, and the initial time gap is usually relatively short. Natural
spaces are best emulated by setting SHAP at a middle value and adjusting SPRD for the desired
effective pre-delay.
