It is precisely this self-adjusting behavior that
makes optical compressors the tool of choice for
smoothing out vocals, bass guitar and full-
program mixes without destroying perceived
dynamics.
Enabling or disabling the Leveler
The Leveler models the LA-2A so closely, it also
models the time it takes for an actual LA-2A to
“warm up” after it is turned on. Therefore, when
you enable the Leveler, give it a moment to “settle”
before you begin processing signals with it.
Gain Reduction
Gain Reduction (Figure 9-7) sets the strength of
the signal sent to the AGC model.
Makeup Gain
Makeup gain (Figure 9-7) amplifies the output
signal to make up for gain reduction.
Limit button
The Limit button (Figure 9-7) models the original
LA-2A Limit/Compress mode switch. The effect is
very subtle, with the Limit option behaving only
slightly more like a limiter than a compressor. The
switch increases the level of the input to the AGC
model and runs the attenuator at a slightly lower
level. The Leveler then responds more strongly to
transients, but otherwise still behaves like a
leveling amplifier.
REVERB
Use the enable/disable button (Figure 9-8) to turn
the reverb processor on or off. Since reverb uses
considerable DSP resources, it is best to leave it off
when you are not using it.

Routing inputs and groups to the reverb
processor
The reverb processor is a single, independent unit
that provides stereo reverb. You can route any
input channel or Group bus to the Reverb
processor with the Reverb send on its channel
strip. All incoming signals to the reverb processor
are merged and processed together. The resulting
stereo output from the reverb can then be merged
into the Main Mix bus with the Main send on the
Reverb channel strip (item #8 on page 21).
Reverb Time
Reverb time (Figure 9-8) determines the length of
decay, or tail , of the reverb. The knob’s range is
from 100 milliseconds to 60 seconds.
Predelay
Predelay is the amount of time before the acoustic
energy from the source returns to the listener,
after reflecting off the surfaces of the listening
space. The very first reflections helps you perceive
information about the listening space, (size,
distance, surface type, etc.). In large rooms, it takes
a while (on the order of milliseconds) before the
