oice Actuator
The Variable Control Voice Actuator (VCVA)
is a function that starts recording automatically
when the microphone senses that sounds have
reached a preset threshold volume level, and
automatically pauses when the volume drops
below the threshold. The VCVA feature allows
you to conserve memory by automatically
stopping recording in instances like long silent
periods during meetings.
When this is enabled,
VCVA
will appear on the
display.
1 Set the VCVA in the menu to [On].
Refer to P.33 regarding each menu item settings.
2 Press the REC button to start recording.
When the sound volume is lower than the preset
actuation sound level, recording automatically
stops after 1 second approximately, and “Stand
by” flashes on the display. The record indicator
light glows orange and
(Record indicator)
appears when recording starts and flashes when
recording pauses.
Adjust the Start/Stop Actuation Level
While the recorder is in recording mode,
press the 9 or 0 button to adjust the
actuation level.
The VCVA level can be set to any of 15 different
values. The higher the value is, the more sensitive
the recorder can react to sounds. At the highest value,
even the faintest sound will activate recording.
The VCVA actuation level can be adjusted according
to the ambient (background) noise.
Notes
• The start/stop actuation level also varies depending on
the selected microphone sensitivity mode ( ☞P.23).
• To ensure successful recordings, prior testing and
adjustment of the start/stop actuation level is
recommended.
• If the recorder detects an input that exceeds the Start
level, the dotted line of the Level meter indicator will
change to the full line, and the recorder starts recording.
