Chapter 10: TL Space TDM and TL Space Native 97
Group Selectors
TL Space presents reverb controls in five differ-
ent groups. Each group is activated by selecting
the corresponding selector.
Levels
The Levels group provides control of the overall
input and output of the reverb, including indi-
vidual controls for early and late reflections, and
independent front, rear, and center levels for
surround outputs.
Input
Cuts or boosts the input signal level from
–inf dB to +12 dB.
Output
Cuts or boosts the output signal level
from –inf dB to +12 dB.
Early
Cuts or boosts the levels of the early reflec-
tions from –inf dB to +12 dB.
Late
Cuts or boosts the levels of the late reflec-
tions from –inf dB to +12 dB.
Front/Rear/Center In quad and 5.0 channel out-
put modes, Cuts or boosts the front, rear, and
center signal levels from –inf dB to +12 dB. In
5.0 output mode, the level of the Center chan-
nel is affected by both the Front and Center con-
trols.
Delays
The Delays group allows control of delay tim-
ings for the reverb. When changes are made to
any control in the Delays group, the IR wave-
form is recalculated and displayed in the Wave-
form display.
Pre Delay
Adjusts length of the Pre Delay from
–200 to +200 ms. The Pre Delay is the time be-
tween the direct sound and the first reflection.
Increasing the Pre Delay often changes the per-
ceived clarity of audio such as vocals. Pre Delay
adjusts the delay of the overall impulse and af-
fects both the Early and Late portions of the IR
equally.
Pre Delay can be set to negative values to allow
for subtle or radical changes to the reverb. For
example, a small negative Pre Delay setting can
be used to eliminate the early portion of an IR. A
large negative Pre Delay setting lets you use the
very end of a reverb tail for creative sounds not
possible with standard reverbs.
Late Delay Adjusts length of the Late Delay from
zero to +200 ms. The Late Delay is the time be-
tween the Early Reflections and the Late Reflec-
tions or tail of the reverb.
Increasing the Late Delay control from zero al-
lows the reverb tail to be delayed so that it does
not start immediately after the early portion of
the IR. As Late Delay is increased, the reverb tail
starts later in time and makes the reverb space
sound larger. Large amounts of late delay can be
used to achieve creative effects not possible with
standard reverbs.
Front/Rear/Center Delay
In quad and 5.0 chan-
nel output modes, adjusts length of the Front,
Rear, and Center Delays independently from
zero to +200 ms.
