4.0 Getting Around the FDS-388
The Split keys (Left and Right) are used to select which of the two channels in
the FDS-388 is being displayed and whether the user wishes to control one or
both of the channels simultaneously.
The two leds indicate whether the FDS-388 channels are linked and controlled
together or split and controlled individually. If both split leds are on
continuously then the two channels have identical parameter values
throughout and are linked together when any parameter is adjusted. If one led
is flashing then the parameter values for left and right are different. The led that
is NOT flashing is the one which is being controlled and displayed on the
screen. The user can switch between the channels to see the parameter values
for left and right whilst linked but both parameters are adjusted when the
encoder knob is turned.
If only one led is on then only one channel can be adjusted and displayed at a
time. This could be used, for example, for making fine adjustments to one side
of a stereo pair. The led that is on indicates the controlled and displayed
channel. The user can select between the two channels by pressing the
individual L and R buttons. Once the user has pressed the two Split keys to
return to linked operation, one of the leds will flash to show that the two
channels now have different parameter values.
There are several important points to note about the Split mode operation.
$ The FDS-388 was designed primarily as a stereo unit. All programs and
card files are stored as Left and Right pairs and it is not intended for the user
to be able to store the two channels independently. The user can program
the two channels for quite different purposes (e.g. Left front of house and
left delay tower in one FDS-388) but he or she should be aware that the
complete setup will be stored in a single stereo program.
% The left and right split leds will not flash if the left and right mutes or gain
trims are set differently.
& Parameter value can be set to different values while in split operation and
will hold those different values when the unit returns to linked operation.
When the parameter is now adjusted in linked mode the left and right
parameters behave in one of two ways depending on what type of param-
eter is being controlled.
Variable parameters such as a filter frequency or a gain value will move
with the offset between the left and right values preserved. If either value,
left or right, hits the limit of the parameter’s travel then the parameter
cannot be moved further. The offset is preserved.
Switched parameters such as the Bell/Shelving switch in the EQ Utility
section will jump to the same, displayed value when the parameter is
adjusted.
