TV Screen & Selectors

The “TV screen” at the top of the main section is a multi-function display and control
center for the input and output routings and effect controls. The three buttons at the top
of the display select the current function of the display—Effect, Inputs or Outputs.

Effect

E

Note:

Effects have to

be placed into an insert
location before you can
program them.

Select the

Effect

display view in the main section, then click on an Effect Insert to

display the effect parameters. If an insert effect is not selected, the display will read “No
Insert”.

Most effects have a wet/dry mix parameter to control the ratio of effect-to-plain signal.
The wet/dry setting is stored with the FX preset. The parameter set varies with the type of
effect.

See “Core Effects Descriptions”

for detailed information about the individual

effects.

When a Send or a Send/Return insert is selected with the FX display enabled, the TV
screen shows you where the Send is going and where the Return is coming from. The
buttons at the top of the display allow you to bypass or solo the Send/Return insert.
