Out Gain The overall gain or amplitude at the output of the effect.
Fdbk Lvl The percentage of the reverb output to feed back or return to the reverb input. Turning up
the feedback is a way to stretch out the duration of the reverb, or, if the reverb is set to
behave as a delay, to repeat the delay. The higher feedback is set, the longer the decay or
echo will last.
Xcouple LaserVerb & LaserVerb Lite are stereo effects. The cross-coupling control lets you send the
sum of the input and feedback from one channel to its own LaserVerb effect (0% cross
coupling) or to the other channelÕs effect (100% cross coupling) or somewhere in between.
This control is not available in Mono LaserVerb.
HF Damping The damping of high frequencies relative to low frequencies. When set to the highest
frequency (25088 Hz), there is no damping and all frequencies decay at the same rate. At
lower frequency settings, high frequency signal components will decay faster than low
frequency components. If set too low, everything will decay almost immediately.
Pan The Pan control is available in the Mono LaserVerb. The left and right inputs get summed
to mono, the mono signal passes through the LaserVerb, and the Þnal mono output is
panned to the left and right outputs. Panning ranges from -100% (fully left), through 0%
(centered), through to 100% (fully right).
Dly Coarse You can set the overall delay length from 0 to 2 seconds (3 PAU) or 0 to 1.3 seconds (2
PAU). Lengthening the delay will increase the duration or decay time of the reverb. To
reduce LaserVerb to a simple delay, set the Contour and Feedback controls to 0. Use a
delay of about half a second as a starting point.
Dly Fine The delay Þne adjust is added to the delay coarse adjust to provide a delay resolution
down to 0.1 ms.
Spacing Determines the starting pitch of the decending buzz and how fast it decends. The Spacing
parameter sets the initial separation of impulses in the impulse response and subsequent
rate of increasing impulse separation. The spacing between impulses is given in samples
and may be a fraction of a sample. (A sample is the time between successive digital words
which is 20.8 µs or 1/48000 seconds.) For low values, the buzz starts at high frequencies
and drops slowly. At high values the buzz starts at a lower pitch and drops rapidly.
Contour Controls the overall envelope shape of the reverb. When set to a high value, sounds
passed through the reverb start at a high level and slowly decay. As the control value is
reduced, it takes some time for the effect to build up before decaying. At a value of around
34, the reverb is behaving like a reverse reverb, building up to a hit. When the Contour is
set to zero, LaserVerb is reduced to a simple delay.
