Touching one of these edit buttons selects one of the four sections (limiter,
compressor, expander, gate) of the dynamics processor for adjustment. The
corresponding parameter values appear in the fields above the rotary encoders
and can be adjusted.
Selects the dynamics unit's input level for adjustment in a 0 to +24 dB range.
Ratio (Compressor only). The compression ratio is displayed as a ratio and can be
adjusted in a range of 1:1 (no compression) through 20:1 (heavy compression)
with the rotary encoder below the field.
Threshold The limiter/compressor threshold is displayed in dB and can be adjusted in a
48 dB range with the rotary encoder below the field.
The limiter/compressor attack time is displayed in ms (milli-seconds) and can
be adjusted in a range of 0.2...20 ms with the rotary encoder below the field.
The limiter/compressor release time is displayed and can be adjusted in a
range of 10 ms to 10 s with the rotary encoder below the field.
Ratio (Expander only). The expansion ratio is displayed as a ratio and can be
adjusted in a range of 1:1 (no expansion) through 20:1 (heavy expansion)
with the rotary encoder below the field.
(Gate only). The gate attenuation is displayed in dB and can be set in a range
from Max. (i.e. mute) to 0 dB (zero attenuation) with the rotary encoder
below the field.
Threshold The expander/gate threshold is displayed in dB and can be adjusted in a 96 dB
range with the rotary encoder below the field.
(Gate only): Please note that the gate has a fixed 6 dB hysteresis. This means
that the gate is closed as soon as the level is equal to or below the adjusted
threshold value; it opens again as soon as the level exceeds the threshold
value by more than 6 dB.
The expander/gate attack time is displayed in ms (milli-seconds) and can be
adjusted in a range of 0.2...1 ms with the rotary encoder below the field.
The expander/gate release time is displayed and can be adjusted in a range
of 10 ms to 10 s with the rotary encoder below the field.
ON The upper four ON buttons individually enable/disable the sections of the
dynamics processor; they are highlighted if active.
The lowest ON button enables/disables the whole dynamics processor. If
some or all sections have been enabled individually but are disabled now by
the lowest button, their individual ON buttons remain highlighted, but the
dynamics curve is displayed in gray.
Reset
For resetting all dynamics parameters of the current channel at once, a desk
hardware key can be configured (SW V5.0 and up).
