TIP
Always adjust the predelay according to the basic shape
you have chosen. Small rooms with a long predelay, for
example, sound very unusual.

above the display you will get a pop-up window.
Here you can choose a scaling factor for the room
size. A scaling factor of 1.0 is the original room size.

parameter is used to increase the reverb decay's den-

The input to the TC SX-1 Reverb
High Cut Filter
algorithm is processed with a low pass filter which
allows you to "roll off" the high frequencies of your
reverb effect. In general, you will want to make your
reverb effect a bit darker than the source signal, as it
might otherwise sound unnatural or even unpleasant.
Above the
HIGHCUT FILTER
dow, there are two frequency values displayed. The
value is the start frequency of the high cut filter,
which is the lowest frequency influenced by the fil-
ter. The value is the end value. This frequency is

The slider to the window's right adjusts the actual
high frequency cut. And, the slider at the bottom of
the window adjusts the frequency position where

DECAY/FREQUENCY
tail of reverberation that happens after the initial
burst. The Decay block receives its input from the
early reflection. Decay time can be edited distinctly
in 3 frequency ranges: low (L), mid (M), and high
(H). And the frequency-ranges themselves can also
be modified.
For each band you can set the decay time between
0.25 and 64 seconds. The sliders to the right of the
window adjust each band's decay time. The two slid-
ers at the bottom of the window set the 2 crossover
points between the 3 frequency-ranges.
TIP
When designing your reverb, keep in mind that room
acoustics lose their high frequency energy more easily
over time. Setting the High Decay to a large amount of
time will usually make the room sound more artificial.
The predelays determine the starting
