What are the main features of the LS-10S?

The LS-10S Linear PCM Recorder is a high-quality digital audio recorder derived from Olympus’ decades of experience in the recording field. At its highest quality setting, the LS-10S records WAVE files in 24 bit/96 kHz Linear PCM (Pulse Code Modulation) format —exceeding the file properties of a commercial audio CD. The LS-10S also records in MP3 and WMA (Windows Media Audio) formats, offering a potential recording time of over 69 hours using the 2 GB of built-in flash memory. The device also accepts SD and SDHC memory cards, further extending the recording capabilities of the recorder.

Music can also be downloaded to the recorder via a USB connection so that the LS-10S can also function as a music player. Music can be saved to the SD or SDHC memory cards so that individual music libraries can be conveniently interchanged in the recorder. Since the LS-10S is a mass storage class device, it can also be used as a USB flash drive (e.g. JumpDrive®) to transfer data and image files from one computer to another.

Olympus has developed new high-sensitivity microphones and microphone amplifier circuitry so that the LS-10S captures studio and broadcast quality sound. Accessory microphones can be used with the LS-10S via its stereo microphone jack, and the recorder can supply power to microphones requiring power. Audio from another device can also be imported into the LS-10S via its LINE IN jack.

The LS-10S Linear PCM Recorder is ideal for any musician or nature enthusiast looking to record audio in the highest possible quality. The recorder is also an ideal tool for broadcast journalists. Its small size, battery power, and ease of operation make it a go-anywhere solution for high-quality audio recording.

What does it mean that the LS-10S is a "mass storage class" device?

Describing the LS-10S as a mass storage class device means that the internal memory and the SD memory card can be used as portable memory to save and transfer files from one computer to another in the same manner that JumpDrive® and other USB flash memory drives, commonly called “thumb” drives, are used. Text files, images, music, and other files can be saved to the LS-10S and accessed from or downloaded to a computer when the device is connected to it using the bundled USB cable. When connected to a computer, the LS-10S appears as a drive.

What are the differences among the various recording mode options?

The LS-10S provides numerous options for recording audio and transferring music to the recorder. The primary differences among the three audio formats employed by the LS-10S — Linear PCM, MP3, and WMA — are compression or lack of compression. The quality settings within each of those formats are defined by the level of detail in the digital record of the recorded sound.

A wide and high frequency response (expressed in Hz or kHz) results in a higher-quality recording, but that quality requires a much greater usage of memory capacity than a lower-quality file.

A high bit rate (expressed in kilobits per second, or kbps) results in a higher-quality recording, but that quality requires a much greater usage of memory capacity than a lower-quality file.

The bit depth also effects quality and file size. The difference between 16-bit and 24-bit bit depth is in the frequency at which sound waves are sampled as part of the digital record of the recorded sound. For most purposes, 16-bit bit depth is more than adequate.

The following information briefly describes the properties of the audio formats the LS-10S uses:

Linear PCM
Linear PCM (Pulse Code Modulation) is a WAVE audio format file. WAVE is the most widely used audio format mainly because it is the format used in commercially available music CDs. Linear PCM is an uncompressed format with a wide frequency response. Therefore, the files are very large and use a great deal of memory. Because of the size of the files, WAVE files are very difficult to send through the Internet. The table below shows the overall frequency response of the Linear PCM format recording modes used in the LS-10S:

Recording Mode Overall Frequency Response
96 kHz 20 Hz to 44 kHz
88.2 kHz 20 Hz to 42 kHz
48 kHz 20 Hz to 23 kHz
44.1 kHz 20 Hz to 21 kHz
44.1 kHz/mono 20 Hz to 21 kHz

The 44.1 kHz setting is similar to the one used in commercial music CDs and its frequency response is the closest to human hearing. The higher settings may have usefulness in scientific applications.

MP3
MP3 (MPEG-1/MPEG-2 Audio Layer 3) is a highly compressed audio format file with a compression ratio of approximately 11:1. It is popular because its compression produces recordings with smaller file sizes that are easier to send through the Internet, enabling music downloads. The files also require much less memory than other formats, making portable music players viable. The trade-off is lower-quality sound, but since most MP3 files are played through earbuds and lower-quality speaker systems, the quality is acceptable.

The table below shows the overall frequency response of the MP3 format recording modes used in the LS-10S:

Recording Mode Overall Frequency Response
320 kbps 50 Hz to 20 kHz
256 kbps 50 Hz to 20 kHz
128 kbps 50 Hz to 17 kHz
mono 50 Hz to 13 kHz

WMA
WMA (Windows Media® Audio) is popular because it is supported by Windows Media Player, which is native to Windows® computer platforms. It has a very low compression ratio that is slightly lower than 2:1. Therefore, it creates detailed digital audio files that use a great deal of memory. However, recording at a 64 kbps bit rate can extend recording capacity significantly.

The table below shows the overall frequency response of the WMA format recording modes used in the LS-10S:

Recording Mode Overall Frequency Response
160 kbps 50 Hz to 19 kHz
128 kbps 50 Hz to 19 kHz
64 kbps 50 Hz to 15 kHz
mono 50 Hz to 13 kHz

What is the purpose of the LINE IN jack?

The LINE IN jack is intended to input recordings from the earphone jack of other audio devices such as radios, music players, microcassette and digital voice recorders, and computers. The process is known as “dubbing.” It is not recommended to input audio from such devices through the MIC jack.

Olympus makes a KA-333 Compaticord (item# 145122) that can be used for dubbing. It can be purchased from authorized Olympus dealers or directly from The Olympus Store online. To order from The Olympus Store, click this link: https://emporium.olympus.com/innards/empProdDetails.asp?sku=145122-410.

How are the settings on the MIC SENSE switch used?

The MIC SENSE switch has a LOW and a HIGH microphone sensitivity setting to select how the microphones will capture sounds in different recording situations.

  • HIGH: This is a highly sensitive mode which will pick up surrounding noises.
  • LOW: This is a normal mode of microphone sensitivity and should be used when the sound level is high, such as recording a band. It can also be used for close-in voice recording, such as dictation.

The MIC SENSE switch also controls the microphone sensitivity of accessory microphones plugged into the MIC jack.

How are the recording sound levels controlled?

There are two options for setting the recording levels — Auto and Manual. Both are set in the LS-10S menu using the Rec Level function.

In the Auto setting, the recorder automatically sets the recording level in conjunction with the microphone sensitivity setting. If there is a sudden spike in the loudness, it automatically compensates the sound level to prevent distortion of the loud sound event.

In the Manual option, the sound level is set using the REC LEVEL dial on the right side of the recorder. The user has the option of applying the Limiter when using the Manual option. The Limiter compensates the sound level of a spike in loudness; much like the Auto setting does automatically. It is recommended to do a sound test and monitor the sound levels on the Level meter on the LCD screen when using the Manual recording mode.  The Level Meter looks like this:

When setting the sound level, set the maximum level to –6dB on the Level Meter. –6dB is highlighted in red in the photo above. This is to prevent clipping. Clipping is distortion that occurs when the sound level exceeds the dynamic range of the recording device. The top of the dynamic range is represented by 0dB. The reason –6dB is used as a practical limit is to give the recording some “head room” to keep the recording cleaner and free of distortion.

What is the purpose of the LOW CUT switch?

The recorder has a LowCut Filter function to minimize low-frequency sounds and record voices more clearly. This function can reduce noise from air conditioners, projectors and other types of "white noise."

What is the purpose of the A-B REPEAT button?

The A-B Repeat button enables repeated playback of part of a file being played. It is used to select the beginning of the segment (A) and the ending point (B). Once the length of the segment has been defined, the file can be played back repeatedly. The selected segment can be unlocked by pressing the A-B Repeat button again.

  • Off
  • Rec Mode
  • Index
  • Reverb
  • Property
  • Light
  • Rec Level
  • Play Mode
  • Memory Select

The Fn button is located beneath the orange Erase button on the lower left side of the LS-10S front face.

What is the purpose of V-Sync. Rec?

Voice sync recording starts when a voice louder than the voice sync level (detection level)is detected. When the voice becomes quiet, recording is automatically stopped. When voice sync recording is on and the voice is below the voice sync level (detection level) for longer than the specified detection time, the recorder stops.

Setting

On: [1 second], [2 seconds], [3 seconds], [4 seconds], [5 seconds], [10 seconds]:Sets the detection time. If the input (recording level) is equal to or below the specified level for longer than the detection time the recorder stops.

Off: Disables this function.

I recorded with an accessory microphone and when I play my files I can only hear playback in the left stereo channel. Why?

If you recorded using a monaural microphone, the recording will only be saved to the left stereo channel. You must use a stereo microphone to record on both the left and right stereo channels.
