Software Setup
The  MOON 850P preamplifier includes powerful 
software that allows you to configure it to meet your 
specific needs. For each of the seven (7) inputs, 
you can assign a 
label
 to replace the factory 
assigned name (i.e. B1, S1, etc.), assign a 
maximum 
volume
 level of less than 80.0dB, create an 
offset 
volume
 level ranging from –10.0dB to +10.0dB, 
bypass
 the volume control (to exclusively use the 
source component’s volume instead) and 
disable
 the 
input completely when it’s not in use. As well, you 
can assign any and all inputs to activate each of the 
850P’s two 
12 Volt triggers
. Finally, there’s a 
facility to reset all software settings back to their 
factory defaults. 
Please refer to the accompanying quick reference 
diagram for a snapshot of the entire Setup menu 
layout. 
When you are in Setup mode, there are three (3) 
front panel items used to program this preamplifier; 
The “Setup” button for navigating up and down 
through the various menu levels, the rotary volume 
control for scrolling through the available choices  
within each programmable item, and the “OK” 
button for confirming and saving your selections. 
What follows are step-by-step examples of how to 
configure an input, assign the two 12 Volt triggers 
and reset the software back to the factory default. 
We will begin by walking through all 5 available 
options for the “B1” input: 
1.  To enter the Setup mode, begin by pressing the 
“Setup” button; “SETUP” will appear in the 
display window. 
2.  Rotate the volume control clockwise until 
“INPUTS” appears in the display. Press “OK”. 
3.  Rotate the volume control clockwise until “B1” 
appears in the display. Press “OK”. 
4.  “LABEL” will appear in the display. Press “OK”. 
5.  “AUX1” will appear in the display. By rotating 
the volume control clockwise, you will scroll 
through more than 25 generic choices appearing 
in alphabetical order (AUX1 … CD … TUNER, 
etc.), various MOON source model names (i.e. 
ANDROMEDA … ORBITER, etc) and finally a 
choice called “CUSTOM” which allows you to 
create your own text label of up to 8 characters 
in length (refer to the example at the end of 
this section for more details). W you assign the 
‘’B1’ input label to “MiND” (for the 
MOON 
intelligent Network Device
 music streamer), you 
are also automatically configuring this 
component’s internal software which will allow it 
to operate with the MiND app, provided that the 
proper SimLink connections have been made 
with your other MOON components. Functions 
available using the MiND app are discussed in 
the next section. 
6.  When the label name you wish to assign to the 
B1 input appears in the display, press the “OK” 
button. “SAVED” will briefly appear in the 
display followed by “LABEL”. 
7.  Press the “Setup” button and the label you’ve 
just assigned to the B1 input will appear in the 
display. 
8.  At this point you can (i) continue configuring 
other options for the B1 input (see the next 
step), (ii) configure another input such as B2 
(rotate the volume control clockwise to access 
the B2 input), or (iii) leave the Setup mode  
(press the “Setup” button once and “INPUTS” 
appears in the display; the press it again and 
“EXITING” will appear in the display). 
9.  The next option to configure for the B1 input is 
the maximum volume setting. Press “OK” and 
“LABEL” will appear in the display. Then slowly 
rotate the volume control clockwise until “MAX 
VOL” appears in the display. Press “OK” and the 
factory default of “80.0dB” will appear in the 
display; this is the maximum volume level.
