Unit
Unit of measurement for the delay. Note that selecting unit of measurement for length (mm, m, inch, feet,...)
the amount of delay (distance value) will depend on the air temperature as indicated in the “environmental
settings” (see “Setup page”).
6.1.3 Compressor
Fig.45 Input compressor block: parameters and visualization.
Each input channel has a dynamic processor placed after the input level control, which can work as
compressors (“Compressor Mode”) or as limiters (“Limiter Mode”). When a dynamic processor is enabled the
graph shows the dynamic curve, i.e. the relation between the input level and output level.
On
This parameter enables or disables the dynamic processor.
Limit
This parameter enables or disables the “Limiter Mode”: enabling this mode the compressor acts as a limiter
(with a ratio ∞:1).
Thresh
Threshold level for the compressor/limiter; below the threshold non compression/limiting occurs, above the
threshold the processor start to compress or to limit the signal as indicated in the dynamic curve. The
threshold level is referred to the maximum dynamic for the input signal, so Thresh=+21dB means
“compressor disabled (over the maximum signal level)”.
Atk
Attack time for the compressor: determines how quickly the compressor reacts to signals above the
threshold.
