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 phono 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.
