Features and specifications are subject to change. Visit www.sounddevices.com for the latest documentation.
• limits your sampling rate to 48 kHz
• limits your bit depth to 16 bit
• limits recording to only one storage medium at a time
.MP3
MPEG-1 Layer III is a lossy compression algorithm often used for music.
What to consider when recording to MP3:
• No BEXT or iXML data
• limits your sampling rate to 48 kHz
• limits your bit depth to 16 bit
• limits recording to only one storage medium at a time
• Auto save feature does not apply to MP3 files, if power is lost during recording the file maybe
invalid.
The chart below indicates the limitations of all file types available on the 702.

* For MP2-Stereo, the per-channel bit rate is half of the selected bit rate.
** MP3-Stereo uses Joint Stereo Coding, which improves per-channel resolution over MP2-Stereo but
can not be quantified into a specific per-channel bit rate.
iXML
The 702 includes iXML (revision 1.5) data in addition to the broadcast wave extension data. For
iXML-aware software applications this data is available. For applications that don’t recognize iXML,
this information is ignored.
Notes
iXML supports notes fields. From the File Viewer select OPTIONS, then Notes.
Using an external keyboard via the CL-1 Remote Control and Keyboard Interface the entry of notes
is much quicker than using the Rotary Switch.
