VIRTUALIZER PRO DSP2024P
AUTO PANNING: This sound effect, which was very popular in the beginnings of stereo technique, is achieved
by allowing a sound source (often the lead guitar or a synthesizer) to wander from one end of the stereo image
to another or by just letting it wander repeatedly.

2.4 Dynamic effects
COMPRESSOR/LIMITER: When the signal level exceeds the level control limit of the signal-processing unit,
it must be limited dynamically to avoid distortions. This is achieved by installing a compressor or a limiter. The
limiter abruptly limits the signal above a specified threshold, while a compressor acts “softly” over a large
range.
EXPANDER: Background noises of all types (noise, humming etc) limit the dynamic range of the actual signal.
As long as the level of the actual signal lies significantly above the background noise, the noise is inaudible.
The interference signal in this case is masked by the actual signal. The expander is used to effectively expand
the dynamic range of signals. Signals with small amplitudes (such as background noise) can be weakened,
thereby reducing the background noise.
GATE: On stage and in studios, there are diverse applications where a noise gate is needed. For example,
microphones that tend to cause feedback can be “defused”. In addition, you can use a gate to eliminate
unwanted noise. When used on vocals, for example, the signal is simply masked during pauses, thus
eliminating all noise. Needless to say, a gate used on vocals has to open very quickly—otherwise, the first
syllables of soft or whispered passages would not be audible.
