Accessories

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:

Quality Mode

PCM 48 kHz mode

40 Hz - 23,000 Hz

 

 

PCM 44.1 kHz mode

40 Hz – 21,000 Hz

 

 

MP3 320 kbps mode

40 Hz – 20,000 Hz

 

 

MP3 256 kbps mode

40 Hz – 20,000 Hz

 

 

MP3 192 kbps mode

40 Hz – 19,000 Hz

 

 

MP3 128 kbps mode

40 Hz – 17,000 Hz
