Will using an accessory microphone with an extended frequency
range improve the quality of my recordings?
Using an accessory microphone with an extended frequency range may not improve the
quality of the recordings in a DM-520. The recorder has an overall frequency response of
40 – 23,000 Hz, but the different quality modes modify the detail of the saved file data
by saving some frequencies and discarding others. This is how the recorder is able to
vary the potential recording time and use the built-in flash memory more efficiently.
The table below shows the overall frequency response in each recording mode:
