The “Input” button is used to select an external

digital source by sequentially scrolling through four

(4) digital inputs: D1 uses an XLR connector for an
AES/EBU digital signal; D2 uses an RCA connector

for a S/PDIF digital signal; D3 uses a TosLink

connector for an optical digital signal and D4 uses a

USB type B connector for use with a computer

equipped with a USB port and music player software
such as iTunes or Winamp. Note: you cannot

connect a USB flash drive or external hard drive to

the “D4” input. The display window will show “D1

AES”, “D2 SPDIF”, “D3 TOS” and “D4 USB”,

depending on the input selected; Four dashes “----”

will replace the input type after approximately 2
seconds. These dashes indicate that the 650D is in

the process of locking onto an external digital signal

– this may take several seconds. Once the 650D

successfully locks onto the digital signal, the four

dashes will be replaced by the sampling rate of this

digital signal. When the signal cannot be locked
onto, “----” remains in the display window. The

MOON 650D is capable of processing an external

digital input signal at one of the following six (6)

different sampling rates: 44.1kHz, 48.0 kHz,

88.2kHz, 96 kHz, 176.4kHz and 192kHz.


The “Random” button, when pressed, will play each

of the tracks on a compact disc in a completely

random order, as opposed to the sequential order as

they appear on the disc. If you have already

created a program of selected tracks, it will play

these programmed tracks in a random order. The
LED located immediately to the left of the “Random”

button will illuminate when you’ve engaged the

random mode.

The “Time” button allows you to scroll through the
four (4) different display modes for time related

information. Each time you press the “Time” button,

the system scrolls to the next time information

mode. By default, the 650D will display the elapsed

time of the track currently playing. The scrolling

order is as follows: (i)

Elapsed time of the current

track. (ii) Remaining time of the current track (iii) Elapsed
time of the entire compact disc (or programmed tracks)
(iv) Remaining time of the entire compact disc (or
programmed tracks).

If you want to turn the display off, press and hold

the “Display” button for 3 seconds. When the

display is turned off, it will still come back on for a

short period of time whenever you press any of the

buttons located on the front panel or the remote

control, using the brightness level that was
previously established; the display will automatically

turn off again once you are done. To turn the

display back on, simply press and hold the “Display”

button for 3 seconds. Finally, the display mode that

you select will continue to be used until you either
select another mode or power down the 650D using

the main power switch located on the rear panel.

To load a compact disc into the 650D, press S to
open the drawer. While the drawer is opening, the

word “OPENING” will appear in the display window,

followed by “OPEN” when the drawer is fully open.

Place the CD in the drawer with the label side facing

up. To close the drawer, press S again; “CLOSING”
will appear in the display window followed by

“LOADING” once the drawer is closed. “LOADING”

indicates that the 650D is reading the CD’s table of

contents. Once the CD is successfully read, the total

number of tracks and total playing time will appear

in the display window. As a result of various copy
protection schemes, some CDs will take longer to

read than others. When you load an incompatible

CD (i.e. data only, SACD, DVD-A or DVD-Video), the

word ‘BAD DISC’ will appear in the display window

and the drawer will automatically open to eject this

CD. Finally, if you inadvertently leave the
drawer open, it will automatically close after

approximately three (3) minutes.

Press X to begin playing a compact disc. Pressing
X while a track is already playing will result in the
current track immediately playing again, starting

from the beginning. Press  to search backward or


to search forward through the compact disc’s

tracks. When you’ve located the track number,

press X to begin playing that track. When you
initiate a forward or backward track change while a

disc is already playing, it will automatically start

playing the track you select; you need not press X.

Press to pause the compact disc currently playing.

The disc will continue spinning and the laser will be

suspended in its current position. Press a second

time or X to resume playing the disc. Press „ to
stop the compact disc from playing. The laser will

return to the start position of the disc.
