Solo; Channel Id Button - Mackie DL806 Reference Manual

Solo

Solo offers the opportunity to audition channel(s) before they are added to the mix. Whenever a
channel's solo button is engaged, only the soloed channel(s) may be heard in the headphones.
Solo buttons illuminate orange when engaged and are gray when disengaged.
Input channel solo buttons are PFL which stands for pre-fader listen. Therefore, the level of the channel
fader does not affect the level heard in the headphones.
Solo is also post-EQ, so if a soloed channel's EQ is engaged, the EQ settings will be heard. But, solo is
unaffected by the position of the mute button.
If no channels are soloed, you will hear the LR signal through the headphones.

Channel ID Button

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 for that channel followed by
a carriage return. 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 that channel's name back to its default name.
True story.
