• Encoders and ENTER, ESC buttons
The DS-SP24 is equipped w ith 3 Relative Encoders, “NAV/PM1”, “PM2” and “PM3”. These
encoders allow you to nav igate the user interface and edit sections of the processor. They al low
the user to navigate with in the sc reen for the selection of sub-menus, pages and parameters and t o
select the values to be assigned d uring the editing operations.
The “ENTER” and “ESC” buttons al low the user to confirm or NOT confirm the operations
performed by the encode rs.
• UTILITY, A/B and 1/2/3/4 buttons
The UTILITY button allows t he User t o enter the Sub-menus and set the general characteristics of
the Processor. The A and B buttons allow the User to enter the Editing Menus of the Pr ocess or's
Input Channels and butt ons 1, 2, 3 a nd 4, allow the User to enter the Editing Menus of the
Processor's Output Channel s.
The A and B bu ttons a s well as the 1, 2, 3 and 4 buttons have double functions dependent on th e
push and hold time.
When the A a nd B butt ons are pushed and held for more than one second Input Chann els A or B
are either MUTED or UN-MU TED. The re d LED will illuminate when the Channel is MUTED. When
the “MUTE” LED is OFF, then the relate d Input Channel is UN-MUTED.
A momentary push of the A and B buttons enters the Editing Mode for the Input Channels (s ee
