Effects and Effect Mode
Effects Overview
Enhancers
Enhancers modify the spectral content of the input signal by boosting existing spectral content,
or stimulating new ones. Two and three-band versions are provided.
Drive
adjusts the input into each band. Increasing the drive will increase the effects. Range is
-79.0 to 24.0 dB.
Xfer
adjusts the intensity of the transfer curves. Range is -100 to 100%.
EQ Morpher
This effect uses two four-band bandpass filters, A and B, and moves between them. This can
produce very convincing human vocal type sounds.
FreqScale
offsets the filter frequencies for each set of filters. After setting the filter parameters
(
Freq
,
Gain
, and
Width
), the FreqScale parameters will move each of the four filter frequencies
together by the same relative pitch. Range is -8600 to 8600 cents.
Morph A>B
. When set to 0% the “A” parameters are controlling the filters, and when set to 100%,
the “B” parameters control the filters. Between 0 and 100%, the filters are at interpolated
positions. When morphing from A to B settings, the A filter #1 will change to the B filter #1, A
filter #2 moves to B filter #2, and so on. Range is 0 to 100%.
Compressors, Expanders, and Gates
A wide range of Compression and Expansion effects is available in the PC3A. The various effects
include
different combinations of:
•
compressors with soft-knee characteristic—the compression action comes in gradually as the
signal level approaches the threshold
•
compressors with hard-knee characteristic—the compression action comes in abruptly when
the signal reaches the threshold
•
expanders
•
multiband compressors that break the signal up into three frequency bands and compress
them all separately
•
sidechains or output EQs
•
reverbs and compressors in combination
•
gates
•
gated reverbs
All of the Compression effects use these parameters:
FdbkComprs
(Feedback Compression) selects whether to use feed-forward (set this to “Out”) or
feed-back (set this to “In”) compression. The feed-forward configuration uses the input signal as
a side-chain source, which is useful when the compressor has to act really quickly. The feed-back
configuration uses the compressor
output
as the side-chain source, which lends itself to more
subtle, but not as quick-reacting, compression.
Atk
(Attack)
Time
for the compressor is adjustable from 0.0 to 228.0 ms.
Rel
(Release)
Time
for the compressor is adjustable from 0 to 3000 ms.
SmoothTime
smooths the output of the expander’s envelope detector by putting a lowpass filter
in the control signal path. Smoothing will affect the Attack or Release times only when this
parameter is longer than one of the other times. The range is 0.0 to 228.0 ms.
Signal Dly
(Delay) puts a small delay in the signal relative to the sidechain processing, so that
the compressor (or gate) “knows” what the input signal is going to be before it has to act on it.
