Effect-Compression; De-Compression - SPL DynaMaxx 9735 User Manual

The EFFECT-COMPRESSION function applies a fixed Release
time of 60ms, but the Attack time is still automated. This mode
increases the perceived loudness in comparison with the normal
Compression mode, and audible compression artifacts can be
generated for creative purposes.
The gain of the audio signal is restored to normal shortly after
the 60 ms Release time has passed, creating deliberate breathing
and pumping effects. The higher the COMPRESS control setting,
the more intense those effects will become. The EFFECT-
COMPRESSION mode is especially interesting when processing
loops, samples or drum sounds.
The LED display provides a visual impression of the increased
processing speed in EFFECT-COMPRESSION mode.
The DE-COMPRESSION function inverts the operation of the
compressor to produce new dynamic headroom, which may be
used to increase the dynamic range of a previously overcom-
pressed signal. The process may also be used to expand the
dynamic range of other sources, such as drum or synthesizer
samples, but the expansion process is quite different to that
normally found in compressors with integral downward expan-
ders. A downward expander means that any signal below the
Threshold will be even lower after processing, but with D
signals above the Threshold are amplified and gain new
headroom. For this process to be musically useful, it was essential
that the time constants were musically automated – fixed time
constants wouldn't do the required job. Perhaps that is one
reason why it hasn't already been incorporated in the many
compressors currently on the market.
Special applications
1. To create a stereo-loop with a difference, try using the
D M with both channels set separately rather than linked
YNA AXX
(STEREO COUPLE off ). Channel one (left side), for example, could
be set to pump and breath heavily by using EFFECT-
COMPRESSION and setting the Compression control to 7 or 8. To
increase the effect, turn up the Compression control to max or
additionally switch in the Soft Limiter.
Channel two could be used in DE-COMPRESSION mode with the
COMPRESS control also set to 7 or 8. For more dramatic action you
can additionally activate the EFFECT-COMPRESSION and the Soft
Limiter. Compensate for the level changes with the GAIN control
and the result is amazing! You can either mix this underneath the
original loop, use it as an effect or.....
2. If you are using drum sounds from samplers or drum
machines, try processing them with DE-COMPRESSION mode: In
addition to adding new life and dynamics to the sounds, indivi-
dual beats get acoustically shorter, which helps them cut through
a busy mix, even at lower levels.
