Only one of the five inputs may be configured for 
the MiND. “B1” is the default input. If, in the 
previous section, you already assigned the “MiND” 
label to one of this preamplifier’s inputs, then there’s 
nothing required to do here – The corresponding 
input has been automatically configured for MiND 
and cannot be changed until you change the input 
‘LABEL” assigments. However, if you haven’t 
assigned the “MiND” label to one of the 850P’s 
inputs, the following example shows how to 
configure an input for MiND functionality:
1.  You may either continue where we left off in the 
previous example by pressing “Setup” twice to 
return to the main menu and the turn the 
volume control until “MiND” appears in the 
display OR enter into the “Setup” mode from the 
beginning by pressing the “Setup” button and 
rotating the volume control until “MiND” appears 
in the display. 
2.  Press “OK” and “MiND:B1” will appear in the 
display. 
3.  Rotate the volume control clockwise until the 
input you want to configure appears in the 
display. 
4.  Press “OK” and “SAVED” will appear brielfy in 
the display followed by “MiND”. 
5.  Press the “Setup” button and “EXITING” will 
appear in the display. 
Assigning a custom label to an input: 
1.  Using the example from the previous page for 
configuring an input, repeat steps 1 through 5. 
2.  When “CUSTOM” appears in the display press 
the “OK” button. The display will show 
“……………………………” . 
3.  Rotate the volume control clockwise to scroll 
through the 26 letters of the English alphabet, 
first in uppercase and then lowercase, followed 
by the numbers 0 through 9, and finally several 
miscellaneous symbols including the space 
character. When you see the letter, number, or 
symbol you wish to use, press “OK” to select it 
and then repeat this step for the next character. 
4.  You must assign all 8 characters when creating 
a custom input label; If your label requires only 
5 characters, you will need to input a blank 
space for the remaining 3 characters. 
Note: If 
you decide to create a custom input label for 
MiND, it must be spelled exactly as it appears 
here – the software is case sensitive. 
5.  Once you’ve filled the last position, press”OK” 
and “SAVED” will briefly appear in the display 
followed by “INPUTS”. 
6.  Press the “SETUP” button to exit from the Setup 
menu
The MOON 850P is equipped with two 12 Volt 
trigger outputs. When an input is assigned to a 12 
Volt trigger, the device connected to the trigger will 
automatically start-up whenever you switch to that 
input. The default setting for all seven inputs is on.  
When you set the IR input to “Y”, all inputs 
previously set to “Y” for that trigger will 
automatically be set to “N”. Then the trigger will be 
controlled exclusively by an external IR signal. The 
following example shows how to configure one of 
them:
1.  You may either continue where we left off in the 
previous example by pressing “Setup” twice to 
return to the main menu and the turn the 
volume control until “TRIG 1” appears in the 
display OR enter into the “Setup” mode from the 
beginning by pressing the “Setup” button and 
rotating the volume control until “TRIG 1” 
appears in the display.
