High-quality linear PCM recording capability
High-sensitivity built-in microphones for high-quality recording
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°.
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.
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.

The directivity of the built-in stereo microphones can be adjusted according to the recorded sound source.
Zoom Mic
This adjustment is recommended when there is a specific sound source to be captured, for example when recording a lecture.
