What is EUPHONY?

The DM-420 features EUPHONY MOBILE – a psychoacoustic surround sound system that combines bandwidth correction, expansion technology and virtual acoustical source processing technology to allow the listener to alter the audio dynamics when playing back recordings through earphones. EUPHONY creates a natural, expansive feel so listeners are less prone to experience a closed-in feeling or to grow tired over extended listening sessions, such as when playing audio books. The options are: OFF, Natural, Wide and Power.

EUPHONY is only applied during playback and cannot be used when recording.

What is VCVA?

Variable Control Voice Actuator (VCVA) is a function that configures the recorder to record automatically only when sound is detected at a pre-set level, and stop when the sound drops below the threshold level. The purpose of the function is to eliminate “dead air” during recordings, thereby conserving memory and shortening file times.

VCVA is enabled in the recorder’s menu. In the DM-420, the VCVA can be set to any of 15 different values. The higher the value, the more sensitive the recorder is to sounds. At the highest level, even the faintest sound will activate recording.

What is the function of the LowCut Filter?

The recorder has a Low Cut Filter function to minimize low-frequency sounds and record voices more clearly. This function can reduce noise from air conditioners, projectors and other types of “white noise.”

What is the function of the Voice Filter?

The Voice Filter cuts low- and high-frequency tones to create a playback frequency range encompassing the tones in the human voice, thereby making the playback of dictation recordings clearer. Voice Filter works in all playback speeds.
