Highlights
Digital recorder with ClearVoice
Low noise microphone
Low-noise microphone
The signal–to-noise (S/N) ratio of the high-
sensitivity microphone is far better than those
of standard microphones. Recording sensitivity
is increased (picks up more voice signal)
without compromising sound quality.
ClearVoice
Recording with good audio quality at lectures
or presentations can be a challenge. Especially
if you do not sit in the front row, the voice of
the speaker may be to quiet too record in
acceptable quality. The ClearVoice feature
adjusts quiet passages dynamically, thus
improving the intelligibility of quieter voices.
Five recording modes
Choose among several recording modes,
including SHQ, HQ, SP, LP and SLP for
extended recording times.
Plug and play
Your VoiceTracer just works - Plug and Play in
Windows, Mac OS and Linux.
Voice volume indicator
Voice volume indicator for clear volume
feedback. The innovative voice volume
indicator directly shows you the sound input
volume on the display.
Large backlit display
The large graphical display lets you view all
important file information at a glance, even in
poor lighting conditions, thanks to the backlit
display.
Ergonomic and lightweight
Small and lightweight, you'll hardly notice it's
with you. Pop it in your pocket or bag and take
it anywhere. The durable casing and attractive,
ergonomic design will make you want to carry
it everywhere you go.
Crystal-clear voice playback
The more powerful front speaker offers a
potent, rich and crystal clear sound
experience.
Hands-free headset included
The hands-free headset is ideal for using on the
move with its tie clip that keeps the
microphone always in the perfect position.
Rapidly transfer recordings
Thanks to the fast data transfer of a hi-speed
2.0 USB connection, transferring recordings to
your PC is up to 40 times faster compared with
the original USB standard.
Index function
The index function helps and eases finding
relevant passages in an instant.
