SURFACE BUTTON CAPS
Every Summa fader has a CUT/
ON button associated with it. The
function of these buttons can be set
from ‘System Settings’ on the touch
display interface.
With functionality set to CUT, the path
attached to the fader will be CUT
when the button is in its ‘ON’ state.
If functionality is set to ON, the path
attached to the fader will be switched
ON when button is in its ‘ON’ state, and
so CUT when in its ‘Off’ state. These
buttons are latching when pressed and
momentary when held.
CUT/ON buttons are made up of blank
key-mats, to which button caps can be
fitted which display the correct ON or CUT
labels depending on how the buttons are
set to function. Summa comes with a full
set of CUT and ON button caps.
CUT BUTTON
Summa has a bank of 12 User
Buttons which can be assigned, using
the GPIO system, to control external
devices, See GPIO in the User Manual
for more information.
Each User Button is lit by a white LED
when activated, either by being pushed or
via a GPI signal.
A template is available to download from
the Calrec website which you can use to
create your own bespoke User Button
labels to be inserted under the User
Button caps.
Alternatively if you wish to make your
own labels without the template, the inner
dimensions of the button caps are: 9mm
x 14mm.
USER BUTTONS
ButtonOperation
Latching: A latching button stays
in its ‘on’ state after being pressed,
for example, the caps lock key on
a QWERTY keyboard is a latching
button.
Momentary: A momentary button
only remains in its ‘on’ state whilst
it is being pressed, for example, the
Shift key on a QWERTY keyboard is a
momentary button.
