MOON 380D Digital-to-Analog Converter

Figure 1: MOON 380D Front panel
The front panel will look similar to Figure 1 (above). The large digital display window indicates the selected digital input (“D1”
thru “D8”) its corresponding sampling frequency in kHz (“44.1” thru “192.0”) of the source material currently being played.
The “Standby” button disengages all outputs from the rest of the MOON
380D’s circuitry and turns off the digital display.
However, when in “Standby” mode, all digital and analog audio circuitry remains powered up to help maintain optimal
performance. The blue pilot LED located directly above the “Standby” button will no longer be illuminated. The “Display”
button allows you to turn the digital display on and off. The “Mute” button mutes all analog output signals. Pressing the
“Mute” button a second time will reinstate all analog output signals. When the output signal is muted, the aforementioned
contents in the digital display window will repeatedly flash on and off.
The two (2) buttons labeled “
◄
Input
►
” allow you to sequentially scroll, either forward “

” or backward “

”
through all the
digital inputs. The inputs are ordered as follows going forward (
►
): “D1”, “D2”, “D3” , “D4” , “D5” , “D6” , “D7” and “D8”.
Inputs “D1” and “D2” accept an AES/EBU digital signal; “D3”, “D4” and “D5” accept a S/PDIF digital signal; “D6” and “D7”
accept an optical digital signal and “D8” accepts a USB type signal for use with a computer (or music server or streamer)
equipped with a USB port and music player software. Note: you cannot connect a USB flash drive to the “D8” input. When
you change inputs, the display window will show the new digital input and briefly four (4) dashes “----”. These dashes indicate
that the MOON 380D is in the process of locking onto a digital signal – this may take several seconds. Once the 380D
successfully locks onto the digital signal, the four dashes will be replaced by the sampling rate frequency of this digital signal.
When the selected digital input signal cannot be locked onto, “----” remains in the display window. The 380D is capable of
processing an external digital signal at one of the following six (6) different sampling rates as shown in the display window:
“44.1”, “48.0”, “88.2”, “96.0” , “176.4” and “192.0” (all in kHz).
A corresponding red LED, located to the left of the display window, will be illuminated - based on selected input type:
“TOSLINK” (for “D6” and “D7”) , “S/PDIF” (“D3”, “D4” and “D5”), “AES” (“D1” and “D2”) or “USB” (“D8”).
In the event that your MOON 380D is equipped with the optional MiND music streaming module, the assigned input is “D9”,
the sampling rate will appear in the display as it does for inputs “D1” thru “D8”, and the red “NETWORK” LED will illuminate.
The “Digital Monitor” button provides for a dedicated loop to be used with either a digital audio component that can record &
playback (DAT, CD-Recorder, etc.) or a digital signal processor such as a room correction device. Pressing this button allows
you to 1) monitor the recording as it occurs on the recording device or 2) engage the effects of the signal processor. The
monitor component’s digital output must be connected to the 380D’s “Digital Monitor In” and its digital input must be
connected to the 380D’s “Digital Monitor Out”. The LED immediately to the right of this button will illuminate when the
“Digital Monitor” function is engaged.
