Bass
The Bass slider defines the reverb decay time for the frequencies below the
Crossover value. Higher Bass values result in longer bass frequency decay
times (when Crossover is not set too low). The Bass reverb decay time value,
in seconds, is shown in the Numerical Display. The available range is 0.6 sec-
onds to 70 seconds.
This control works in conjunction with the Crossover parameter, which defines
the range of the bass frequencies affected by the Bass control. Therefore ad-
justing Bass may have little audible effect if Crossover is set to a very low
value.
Mid
The Mid slider defines the reverb decay time for the frequencies above the
Crossover value. Higher Mid values result in longer high frequency decay
times (when Crossover is not set too high). The Mid reverb decay value, in
seconds, is shown in the Numerical Display. The available range is 0.6 sec-
onds to 70 seconds.
Mid works in conjunction with the Crossover parameter, which defines the
range of high frequencies affected by the Mid control. Therefore adjusting
Mid may have little audible effect if Crossover is set to a very high value.
Mid is a slightly misleading label, because this control actually affects the re-
verb decay for all frequencies above the Crossover value (not just the
midrange). However, because the “highs” in the reverb can be rolled off with
the Treble Decay control (and usually are), the midrange frequencies are of-
ten more prominent than a full-range tail.
Crossover
This control defines the crossover frequency (the split point) between the bass
and upper frequency bands in the reverb tail. Higher Crossover values make
the Bass parameter control a wider range of frequencies. Conversely, lower
values make the Mid parameter control a wider range of frequencies. The
available range is 100 Hz to 10.9 kHz.
Crossover affects the reverb decay because it works in conjunction with the
Bass and Mid reverb time parameters, which both define the length of the re-
verb tail (one control for each frequency band). If those parameters are set to
very short times, the result of adjusting Crossover may be very subtle.
Note: Crossover will have no apparent effect if Bass and Mid are set to the
same value.
