Use the "A324" AC adapter ( sold separately ) if continuous recording is likely to exceed battery life. All recording times listed in this document are potential continuous recording times. Actual recording may be shorter if repeated, short recordings are made. |

2. High Quality Mode uses WMA format |
The "Voice-Trek DS-10" is the first portable recorder to offer Microsoft WMA ( Windows Media Audio ) *1 format in addition to conventional DSS *2 Standard Play
Mode and Long Play Mode recording.
The High Quality Mode uses WMA 32 kbps, 44 kHz sampling rate, monaural recording to achieve extremely close fidelity to the original speech while keeping data volumes low. The "Voice-Trek DS-10" is limited to frequencies below 7 kHz for copyright protection purposes, but its sampling rate of 44 kHz is the same as used in music CDs, and it rigorously suppresses the noise generated by conversion to digital data.

WMA: |

An audio format included as a standard component of Microsoft operating systems since "Windows Me" and featuring both high quality audio and high levels of data compression. A music CD compressed with the WMA format provides quality on par with the original CD using only 48 kbps data. Olympus was one of the first to understand the potential of WMA technology and has worked in close collaboration with Microsoft and Texas Instruments to develop the world's first WMA-format portable recorder. |

DSS: |
"Digital Speech Standard," a standard developed by Olympus, Phillips ( Netherlands ) and Grundig ( Germany ). |

3. Noise cancellation functions |
The "Voice-Trek DS-10" includes noise cancellation functions to achieve clear recording even in noisy environments. This technology, licensed from Cortologic AG, focuses on the unique modulation frequency range generated by the human voice and digitally removes sounds outside of that frequency range, making it possible to eliminate noise in the same frequency band as the voice, something that is almost impossible with conventional filters. The unit comes with three noise cancellation levels, -- OFF / LOW / HIGH -- that can be selected at playback mode according to the amount of noise in the recording.

4. Designed for portability and ease of use |
The "Voice-Trek DS-10" maintains the large buttons and functional layout that won praise for the "Voice-Trek DS-1" and the "Voice-Trek DM-1," but features a rounder body that is easier to hold and naturally guides the fingers to the proper place. The aluminum case gives the unit a touch of elegance and quality, and a new metal clip and a strap hole are included to improve portability.

5. LCD with kanji display functions |
The large, full dot LCD displays hiragana and kanji as well as fast alphanumeric, katakana characters and numerals for easy to read Japanese-language displays of the date, time, mode, file information and warnings. A backlight is included for use in dark environments.
|
6. Repeat playback functions and choice of 3 playback speeds |
The new "repeat playback function" allows the user to repeat any section of a file, a capability requested from those using IC recorders for language learning. In addition to the conventional 1.5 speed "Fast Playback" Mode, the "Voice-Trek DS-10" also has a new 0.75 speed "Slow Playback" Mode. State-of-the-art digital signal processing plays the sound back at the original pitch in fast or slow mode.

7. USB connection kit and cradle for connection to both Windows and Macintosh computers |
The "Voice-Trek DS-10" comes with a USB connection cable and "DSS Player" audio playback software for high-speed data transfers to and from personal computers. The cradle *1 included with a unit makes PC connection even easier -- just set the "Voice-Trek DS-10" on the cradle and you're ready to go.
Recorded audio files can be transferred to a computer and, for example, attached to e-mail.*2 The "Voice-Trek DS-10" is USB audio class compatible and can be used as a USB microphone and USB speaker for Windows computers. *3
When used as a microphone, the unit can record up to about 100 hours directly to hard disk. *4
"DSS Player" is an application designed for users who wish to create text files directly from speech and also comes with convenient functions to play back audio files while using word processing software. "DSS Player" can convert DSS files to WAVE, the standard Windows audio format, and AIFF, the standard Macintosh audio format, so that recordings can be played back on other computers as well.
