FREQUENTLY ASKED QUESTIONS

What is an MP3 file?
• An MP3 (MPEG1, Audio Layer 3) file is an
audio file created using audio data
compression technology.
The MP3 audio format allows you to enjoy
high quality music playback from files that
are a fraction of the size of a normal CD
audio file. You can create MP3 files from
your favorite CDs, or by downloading
songs from the internet and store them on
your PC or MM-FX500 recorder. MP3
files typically end with the extension .mp3
and may also be used with a variety of
other applications such as language
programs and internet broadcasts.
What is a recorded AFX file?
• A recorded AFX file is basically an
encrypted MP3 file. The original MMC
identification code is embedded in the
AFX file by the MM-FX500 recorder during
the recording process.
How is the available memory size
displayed by the Manager software?
• A memory card is composed of blocks. A
whole block will be used even if you try to
store a one-byte file. While some selected
files in the local list box show less than the
available memory size of this model, you
may not be able to download such files to
the recorder.

How do I upgrade the memory?
• You may upgrade the memory by inserting
another MMC card (16MB or 32MB).
These are commercially available.
Why does the LCD display 128kbps when
playing back a recorded AFX file but the
REC MODE menu shows MUSIC 44KHz?
• In the REC MODE menu, MUSIC 44KHz
means music sampling rate. During
playback, 128kbps means music data
transfer rate (bit rate).
Can the MM-FX500 recorder support MP3
files with VBR (Variable Bitrate) format?
• No, the recorder will not support VBR
format.
Is there a standard volume level for MP3
files?
• The volume level of MP3 files (encoded
data from audio CDs) depends on the
software used for encoding.
Is there a standard volume level for
recorded AFX files?
• The volume level of recorded AFX files
(recorded by the MM-FX500 recorder)
depends on the Line-in input level.
How many minutes of MP3/AFX files can
this recorder hold?
• It depends on the memory size of the
recorder. A recorder with 32MB of memory
can hold approximately 30 minutes of the
near-CD-quality sound of MP3/AFX files.
