Detailed Parameter Description
RANGE: Determines the depth of gating or expansion. When
turned fully anticlockwise (Range = 0), this section is inactive.
When turned fully clockwise, a range of 40dB can be
obtained.
THRESHOLD: A Variable hysteresis is incorporated in the
threshold circuitry. For any given ‘open’ setting, the
Expander/Gate will have a lower ‘close’ threshold. The
hysteresis value is increased as the threshold is lowered. This
is very useful in music recording as it allows instruments to
decay below the open threshold before gating or expansion
takes place.
RELEASE: This determines the time constant (speed),
variable from 0.1 to 4 seconds, at which the Gate/Expander
reduces the signal level once it has passed below the threshold.
Note that this control interacts with the Range control.
FAST ATT: Provides a fast attack time (100μs per 40db).
When off, a controlled linear attack time of 1.5ms per 40dB is
selected. The attack time is the time taken for the
Expander/Gate to ‘recover’ once the signal level is above the
threshold. When gating signals with a steep rising edge, such
as drums, a slow attack may effectively mask the initial
‘Thwack’, so you should be aware of this when selecting the
appropriate attack time.
HOLD: Determines the time after the signal has decayed
below the threshold before the gate closes. Variable from 0 to
4 seconds.
Note that when the Dynamics Section is not in circuit, its
sidechain input is also bypassed.
Output Section
The Output Section consists of a ±20dB output gain control,
and a 6-segment LED meter.
S/C LISTEN: Pressing the SC LISTEN switch routes the
sidechain directly to the output, so you can monitor the
sidechain signal
BYPASS ALL: Engaging this button will bypass all channel
processing whilst still routing the signal through Duende. This
avoids the time shift which occurs when a ‘hard’ bypass is
done using the default DAW control, allowing for easier A/B
comparison between processed and unprocessed signals.
