“Fat channel”
To the left of the display is an area containing a num-
ber of encoders and keys.
These controls are dedicated to module functions,
and are divided into three sections: dynamics, EQ,
and Aux sends.
When a channel module is selected, the appropriate
screen can be shown, and the parameters adjusted
using these controls.
These controls also allow you to copy and paste set-
tings between channels.
Other parameters (and protection against overwriting
existing parameters) can be copied using the screen
as described in“UTILITY copying” on page 30.
Full details of EQ and dynamics processors are given
in the section on Modules, but this section explains
how to use these dedicated controls.
NOTE
Some modules do not have dynamics processors, or
equalization, or aux sends (see “About the DM-4800”
on page 11). These controls described here are, of
course, only valid for modules for which the appropri-
ate facilities are available.
Dynamics processors
When a module with dynamics processing has been
selected, press the
SCREEN
key as shown above to
bring up the module’s dynamics screen.
The gate and compressor/expander can then be
turned on and off using the
GATE ON
and
COMP/
EXP ON
keys, respectively (these keys light when
the appropriate processor for the selected module is
active).
Use the
SELECT
key to determine whether the
encoders will affect gate (
GATE
) or compressor/
expander (
COMP/EXPAND
).
These encoders work as follows:
