MRX7-D Owner’s Manual
21
The MRX7-D can use commercially available SD memory
cards to play back audio files such as music and sound effects
without needing to connect a CD player or other audio device.
The MRX7-D can play back audio files in either MP3 or WAV
formats.
Here we explain how to handle SD memory cards. In order to
play back audio files saved on an SD memory card, you must
make settings in MTX-MRX Editor. For details, refer to “MTX-
MRX Editor User’s Manual.”
 Inserting an SD memory card
1. Use a 2.5 mm hex key to open the cover of
the SD memory card slot.
2. With the terminals of the SD memory card
facing downward, insert the card straight
into the slot until it clicks into place.
When the SD memory card has been correctly recog-
nized, the [SD/ACT] indicator (page 9) will light. The
[SD/ACT] indicator will flash while the card is being
accessed.
 Removing the SD memory card
1. Gently press the SD memory card inward.
The card will pop out slightly; gently pull it completely
out.
Here’s how to initialize the MRX7-D’s internal memory, restor-
ing it to the factory settings.
1. Power-off the MRX7-D.
2. Set the rear panel DIP switches 7 and 8 to the
“INIT. (INITIALIZE)” position.
3. Power-on the MRX7-D.
Initialization will start.
The status of execution is shown by the front panel [ALERT]
indicator, the [PRIMARY] through [SYNC] indicators, and
the [YDIF] through [SD/ACT] indicators.
• During initialization:
All indicators other than [ALERT] will flash.
• Initialization completed:
Only the green indicators will flash.
• Initialization failed:
The [ALERT] indicator will flash.
Using the MRX7-D to play audio files
saved on an SD memory card
NOTE
Use an SD format or SDHC format memory card (SDXC format
is not supported). However, depending on the manufacturer or
type of memory card, some memory cards might not work cor-
rectly with the MRX7-D.
NOTE
To prevent theft of the SD memory card, we recommend
that you leave the cover installed during use.
Initializing the MRX7-D
CAUTION
Do not turn off the power to the MRX7-D during initial-
ization. Otherwise, a malfunction may occur.
NOTE
If initialization failed, contact Yamaha representatives /
authorized distributors to have the device inspected. A list of
Yamaha representatives / authorized distributors appears
near the end of this manual.
