Low Cut 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 similar noises.

VCVA
When the microphone senses that sounds have
reached a preset threshold volume level, the
built-in Variable Control Voice Actuator (VCVA)
starts recording automatically, and stops
when the volume drops below the threshold
level. The VCVA feature extends recording
time and conserves memory by stopping
recording during silent periods, which helps
the playback to be more efficient.
1 Select [VCVA] from the menu on
the [Rec Menu].
2 Select [On] or [Off].
[On]:
Enables the VCVA function. Will start
recording in VCVA mode.
[Off]:
Disables this function. Will resume
recording in normal mode.
