Input Panel (IPE-1)
Controls and Functions
Each input panel of the E-1 digital audio control surface has four identical strips
representing four input channels. You control how each channel is set up by pressing
physical switches on the surface and configuring software settings through the Input Tab.
A/B Button - Source Switching
The A/B button located at the top of each
fader strip provides two different functions. The
first use of the A/B button is as a source selector
for the fader strip.
Each fader can be programmed to quickly
switch between two different sources, desig-
nated as the A source and the B source. A quick
press of the A/B button switches that fader
between its A and B sources. The SOURCE
display for that fader indicates the name of the
source currently selected. Thus, if A is currently
selected, its name is shown, and tapping A/B
changes the source to the B source, and at the
same time shows the new name in the display.
If you have the A source currently selected
and have no source programmed as the B source,
then a quick tap on the A/B button will switch off
the A source to that fader, and the display will
say NOSOURCE. If both A and B are pro-
grammed for the same source, tapping the A/B
button will have no real effect.
Note that A and B designations are arbitrary,
in the sense that the operator will not know if the
current source is A or B, but will know only the
name of the currently selected source, which is,
after all, the important piece of information.
A/B Button - Select Mode
Aside from the A/B button, the fader strip
has several other controls. Channel on and off,
fader level, cueing, talkback, and output assign
can all be done from the fader strip, and these
functions are addressed in more detail below.
However, there are other functions we may want
to adjust for each fader. These additional func-
tions are controlled from the master panel. But
how does the master panel know which fader it’s
adjusting?
