FST ATT – Normally, a controlled linear attack time of 1.5ms per 40dB is provided.
Press this button to select a fast attack time (100µs per 40dB). The attack time is the
time taken for the Gate/Expander 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.
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.
HOLD – Determines the time after the signal has decayed below the threshold
before the gate starts to close. Variable from 0 to 4 seconds.
KEY – Switches the Dynamics side chain to the 'KEY' input on the rear panel of the
unit.
LINK – The side chain control signals of multiple modules can be linked by
pressing the LINK switch on those modules you wish to gang. When two (or more)
Dynamics sections are linked, the control voltages of each section sum together, so
that whichever section is the 'loudest' will control the other section, be that gain
reduction or enabling the gate.
Don't try to link two gates using the LINK button when you want the signal on one
to open the other. If you need to achieve this effect, take a keying signal from one
section to trigger the other. The easiest way to do this is by patching from the
'source' signal to the Key input of the 'destination' channel, and selecting KEY (see
above) on this module.
Note that the side chain signals for the X-Rack Mono and Stereo Dynamics modules
(XR618 and XR728) differ slightly such that there will be a 4dB difference in the compressor
and gate thresholds between the two types of module should the link function be used to
combine both mono and stereo side chains.
