What are Recording Scenes? 

Recording scenes are essentially sets of recorder settings that can be enabled all at once 
by making a single menu selection. This function is located in the Rec Menu as 

Rec Scene

The DM-420 has six recording scene options. Three are pre-set out of the box; each is 
optimized for recording in specific conditions. The other three are reserved for 

User 

Settings

,

 

allowing for customization to suit your preferences. To enable a 

User 

Settings 

 scene, select one of the available 

User Settings

 options and then choose 

Scene Save

. The recorder’s current configuration will be saved as a scene. 

The table below shows the menu settings that are applied in each of the preset 
Recording Scenes as well as the default settings when 

Rec Scene

 is set to 

Off

. Only the 

listed functions are affected when a

What are Playback Scenes?

recorder to preset playback scenarios. The settings that can be saved as a Playback 
Scene are

 EUPHONY

,

 Voice Filter

,

To create a Playback Scene, first configure the recorder with the desired settings. Then,

and

 

select a 

User Setting

 option. 

Finally, press the [

OK/MENU

] button to save the scene. The recorder will save the 

settings of the functions listed above as a Playback Scene. To create another scene, 
create a new mix of menu settings and repeat the process.  
To select a saved Playback Scene for use, in the menu go to 

Play Scene > Scene Select  

and choose the desired 

User Setting

. Press the [

OK/MENU

] button to activate the scene. 

What is the function of Noise Cancel?  

Noise Cancel

 can be enabled to reduce background noise in recordings made in noisy 

surroundings. In effect, the function treats the loudest sounds as the most important 
and reduces other sounds to make the dictation clearer. 
The Noise Cancel options are 

OFF

LOW

 and 

HIGH.

 The options are set in the recorder’s 

menu. The LOW or HIGH settings remain valid until Noise Cancel is set to OFF. Noise 
Cancel is not available while the Voice Filter is set, and it cannot be used during 

Slow 

Playback

 or 

Fast Playback.
