MOON 750 D Digital-to-Analog Converter / CD Transport

Front Panel Controls (continued)

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 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 750D is in the process of

locking onto an external digital signal – this may take several seconds. Once the 750D 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 750D 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, 176.2kHz 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 750D will display the elapsed time of the track currently playing. The scrolling order is as follows:

1.Elapsed time of the current track

2.Remaining time of the current track

3.Elapsed time of the entire compact disc (or programmed tracks)

4.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 750D using the main power switch located on the rear panel.

To load a compact disc into the 750D, 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 750D 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, in the event that 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. In the event that 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.
