Olympus LS-10 - Manual (Page 3)

High-sensitivity built-in microphones for high-quality recording
High-quality linear PCM recording capability
4 5
Long-term recording capability
Recording time can be as long as 16 hours with two AA Ni-MH rechargeable batteries or about 12 hours
with two AA alkaline batteries (both in the 44.1 kHz/16-bit mode). A built-in 2 GB flash memory enables
up to 3 hours 10 minutes of CD quality (44.1 kHz/16-bit) recording or up to 69 hours and 35 minutes of
WMA format recording. The LS-10 is also equipped with an SD/SDHC card slot to add additional
recording capability.
Recommended setups for different applications
Recording settings can be adjusted to suit the needs of different recording situations. Note that the examples
listed in the following table are typical setups that may require further adjustment depending on the target
sound source and ambient conditions. Experiment with the different setups and select the most optimum one.
Multi-format compatibility
Supported recording formats include the MP3 and WMA formats that are widely used in Internet file
distributions and are suitable for long-term recording, as well as the linear PCM (WAV) format. Select the
optimum recording mode according to the purpose and usage of each recording.
Fea

of the LS
-10
Newly developed to accurately capture any
type of sound, the LS-10's high-sensitivity
microphones are accommodated in vibration-
resistant housings made of machined
aluminum. The size and aperture shape of the
housings are designed to optimize basic
microphone performance parameters such a
frequency response and directivity, ensuring
maximum quality. To produce recordings with a
natural, expansive stereo feel, the left and right
microphones are installed in an outward facing
layout at angles of 90°.

• See table on page 15 for the reference recording time of each recording mode. • The maximum capacity per file is limited to about
4 GB with the MP3/WMA formats and about 2 GB with the linear PCM (WAV) format. • The maximum recording time per file is about
26 hours 40 minutes with the WMA format. • The recording time available with an SD/SDHC card varies depending on the card. • Check
the Olympus website (http://olympus.com) for compatible SD/SDHC cards.
High audio quality microphone amplifier circuitry
The microphone amplifier circuitry is divided into
independent left and right channels to eliminate
interference between channels. The analog
circuitry is powered by an independent power
supply provided separately from the digital power
supply. In addition, the system control (digital
processing)
and audio processing use
independent circuit boards to ensure clear signal
transmission and high S/N. Separate system control (digital)/audio processing boards

Recording Situation
MIC SENSE
The directivity of the built-in stereo microphones can be adjusted according to the recorded sound source.
This adjustment is recommended when there is a specific sound source to be captured, for example when recording a lecture.
LOW CUT
Rec Mode
Rec Level
Zoom Mic
For most applications, LOW is recommended to reduce noise. HIGH is better for capturing quiet sounds or voices.
The low-cut filter function can be activated to record the audio more clearly by cutting low frequencies.
Linear PCM (WAV) is recommended for audio quality; MP3 or WMA is recommended for longer recording time.
MANUAL is recommended for wider dynamic range (such as in live recording), and AUTO is recommended for voices in a conference.
