Master Id Button - Mackie DL806 Reference Manual

If the selected output is any aux, the record button will be replaced with a solo
button. Soloing offers the opportunity to audition the selected output and make
any necessary level adjustments to the inputs. The output solo is AFL, so the fader
level will affect the signal you hear in the headphones.
The solo button illuminates orange when engaged and is gray when disengaged.
When any input or output is soloed, a rude solo button will appear below the master
fader's output selector. This serves as a reminder that a soloed channel exists somewhere.
This is especially useful when an output is soloed and you switch to adjust a different
channel on a different output. Tapping the rude solo button will clear all solos on all
inputs and outputs, including the ones you can't see.

Master ID Button

If the name is too long to fit, the button scrolls, displaying the entire name.
For familiarity, this is the same keyboard that is used for messaging or emailing from the iPad.
It goes without saying that tapping "Default Name" changes the master fader's name back
to its default name.
As seen in all of these images, a small name resides in the upper-left corner of the master ID button
regardless of the name and/or image. This system name represents each output and it cannot be
changed or removed. Trust us, it's for the best, as it is for easy identification of each output, even after
you rename it something goofy.
Mackie DL806 and DL1608 Reference Guide
The master fader's name and image is similar to that of a channel
strip's name and image.
Like the channel faders, the master fader's name and image is also
user-editable. Simply tap the button at the bottom of the master
fader and a popover allows editing a name or selecting an image.
Let's start with the name. Tap in the name box to bring up the
blinking cursor and keyboard (as seen in the image below).
Simply type in the name you want followed by a carriage return.
Note the text change between the button shown to the left ["Main"]
versus the one as shown below ["PA"].
