.MP2
MPEG-1 Layer II is a lossy compression algorithm often used for speech recording.
What to consider when recording to MP2:
• time code is enabled (with BEXT or iXML data)
• mono recordings are not allowed with bit rates above 192k
• 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:
• time code is enabled (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 les, if power is lost during recording the le maybe
invalid.

* 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 702T 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.
