Simultaneously recording two files at
different input levels (DUAL REC)
This recorder can simultaneously record a second recording
at a different input level along with the regular recording. For
example, when recording with microphones, you can make an
ordinary recording with the input level set as high as possible
and simultaneously record at a lower input level setting (−12dB)
Two separate recorded files can be saved. One is at the normal
input level and one has its input level adjusted as follows
according to the application and conditions.
• File recorded 12dB lower than the ordinary recording input
• File that avoids distortion when signals that are too loud are

the usual manner. (See “Adjusting the input level” on page
