Dynamics processors
This section covers the use of the DM-4800’s built-in
compressor/expanders and gates.
Compressor/expander dynamics processors are avail-
able in all modules except channel modules 49
through 64.
Gates are available in channels 1 thorough 48 (input
only).
The module screen accessed by the
DYNAMICS key
shows the settings for the currently selected input
channel (as shown by the
SEL indicator).
If the selected channel is linked as part of a stereo
pair, the settings affect both channels.
LINK This and the two trigger settings following,
apply both to compressor/expanders and to gates
(where available). The link features means that both
processors are linked by a common trigger signal.
The two processors must be in adjacent channels of
an odd-even pair (e.g. channels 3 and 4 can link their
processors, channels 4 and 5 cannot).
When two channels are linked, but the processors are
linked, the processor source can be selected.
Trigger mode ( TRG MOD ) is only valid when two
gates or expanders are linked. This option (selected
using the wheel and
ENTER key) allows the trigger-
ing for both processors to be initiated by the left
channel, the right channel, or
BOTH (both channels act
as triggers—in other words, the first channel to be
triggered will automatically activate the second
channel’s processor).
Trigger selection Allows the selection of a chan-
nel (the choice is 1–24 in the case of modules 1
through 24, or 25–48 in the case of modules 25
through 48), the selected module (shown as
SELF ) or a
globally-defined trigger source (see “Input routing”
on page 59), shown as
TRGx as the trigger for the
compressor (this can include a mic/line source routed
to a trigger).
TIP
By feeding an input signal through a channel with EQ
and selecting this as a trigger source, you can imple-
ment sidechain compression, without the use of a single
patch cord!
