MOON i 3.3 Integrated Amplifier
Front Panel Controls
Figure 1: MOON i 3.3 Front panel
The front panel will look similar to Figure 1 (above). The large display window indicates the selected input source. In the
event that your i 3.3 includes the digital input option, additional information will appear in the display window. Refer to the
section entitled “Optional Digital Inputs” on page 8 for further details.
Directly below the display window, from left to right, are seven (7) buttons:
The “Standby” button disengages the input section from the rest of the i 3.3’s circuitry. When in “Standby” mode all audio
circuitry remains powered up to help maintain optimal performance. When switching back from “Standby” to the “on” mode,
the blue LED directly above the button will illuminate, As well, the current ‘input’ will be memorized from the previous listening
session. The blue indicator LED, does not illuminate when the i 3.3 is in “Standby” mode.
The “Display” button allows you to turn the digital display on and off. The “Mute” button mutes the output signal to the
loudspeaker terminals, headphone jack, as well as both the fixed and variable line output connectors (refer to the section
entitled “Rear Panel Connections” for further details). Pressing the “Mute” button a second time will reinstate the volume back
to its previous level. When the output signal is muted, the corresponding red indicator LED, located to the left of the display
window, will flash on and off.
The “Spk off” button fully disengages the output signal only to the loudspeakers connected to the MOON i 3.3. This feature
is very useful when listening to the i 3.3 with headphones. When this function is engaged the red LED located to the left of
the display window will illuminate.
The “MP” button (for Media Player) has its corresponding input connection located on the far right side of the front panel for
easy access. It uses a 1/8” mini-jack connector which is the most common type of connection found on portable media
players. When selected, the corresponding red LED, located to the left of the display window, will illuminate. As well, when the
“MP” input is in use the display window automatically turns off.
The two (2) buttons labeled ◄ INPUT ► allow you to sequentially scroll, either forward (►) or backward (◄) through all of the
available inputs. Depending on the installed options, the order of the inputs is as follows going forward (►):
Basic Unit: “CD”, “A1”, “A2” and “A3”
All options installed: “CD”, “A1”, “A2”, “PH”, “B1”, “D1”, “D2”, “D3” and “D4”
The above abbreviations correspond directly to the labeling of the rear panel inputs. By default the “CD” input is intended for
use with a CD Player, however you can connect another type of source component to it. “A1”, “A2” and “A3” are intended for
use with any type of source component that outputs analog signal. If you have installed the optional ph ono section, the “A3”
input is replaced by “PH”. If you have installed the balanced input option, “B1” will appear after the “A3” / ”PH” input. Finally,
if you have installed the digital input option, “D1”, “D2”, “D3” and “D4” will appear after either “B1” (if you have the balanced
option) or “A3” / ”PH”. The optional inputs only appear if they are installed.
