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

es
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.

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.
