How should I disconnect the LS-100 from a computer?

Before disconnecting the USB cable:

  • Windows - Use the Safely Remove Hardware function in the Taskbar in the lower right corner of the computer's Desktop screen.
  • Mac - Either drag the icon for the recorder on the Desktop screen to the Trash icon and release it, or use the EJECT button.

Failure to disconnect the recorder using the appropriate method may result in corrupted files, which may not be accessible.

Is there newer firmware which enhances the functionality of the recorder?

Olympus America Inc. recently released firmware update 1.10 in August, 2012 for the LS-100 which addressed the following:

1. Improves the latency of the Record Monitor.

2. Adds the capability that allows the recorder to start recording and playing back simultaneously when the REC or PLAY button is pressed during Recording pause while in the Multi-Track mode.

3. Adds the capability to pause playback in Multi-Track mode.

4. Fixes the problem with the recorder displaying the wrong remaining time when it continues recording for a period of time.

5. Fixes the Solo function issue: You may now set it properly in Multi-Track mode.

6. Fixes the problem with the recorder saving an incorrect "create date and time" when a 64GB SDXC card is used.

7. Adds the capability to start recording by pressing once on the REC button on the remote controller when used.

8. Changes the setting to not turn off the LCD when the recorder runs in Metronome mode, Tuner mode, Lissajous mode, Menu mode, or when it is connected to PC.

9. Improves stability of the recorder.

Why can't I hear the playback of my sound files in the Overdub or Play Sync recording modes?

In these recording modes, sound is output only through the earphone jack to prevent feedback.

Return to Top

Why can't I use the FF and REW buttons to skip to the next recording in the Overdub or Play Sync recording modes?

Due to the nature of the recording method, you must first press the List button to return to the list of recordings.

Can I use the AC adapter to power the recorder for recording and playback?

No. Although a computer can power the recorder via USB for downloads, it cannot power it for operations such as recording and playback.

I want to charge spare batteries outside the recorder. Is there a battery charger available?

I pressed the REC button to record, but when I try to play back the file, there is no recording. Why?

The first press of the REC button puts the recorder in the standby mode but does not record. You must press the REC button a second time to start the actual recording.

When the recorder is in the standby mode or is paused, the light around the REC button blinks. In the standby mode, the microphones are active and the LCD displays readouts so that the sound levels can be adjusted. (Use the level meters for the left and right audio channels.)

Pressing the REC button while recording will pause the recording. When paused, pressing the REC button again will resume recording. Pressing the STOP button will stop the recording and close the file.

I want to burn a CD using the CD Write function and an external CD burner, but I can't select some of my recordings. Why not?

The CD Write function is used to create an audio CD that will be playable in commercial CD players, such as may be found in a stereo system or car. Therefore, the function will only operate with files that are already in the format that can be played by commercial players (PCM 44.1 kHz/16 bit/128 kbps/stereo). If you intend to use the CD Write functionality, choose this format when recording.

If you have already recorded files in another format and would like to burn them to a CD, connect the LS-100 to a computer using its bundled USB cable and then transfer the files to the computer. Then you can use many CD burning software titles supported by the computer to create CDs from files in other formats.

I'm trying to perform Overdub, Play Sync and Multi-Track operations on files in the high-quality PCM and mp3 formats and am finding these formats aren't able to be used. Why not?

These operations can only be used on files in the PCM 44.1 kHz/16 bit/128 kbps/stereo audio format, which is the format used to create commercial music CDs.

I've owned Olympus digital recorders that use VCVA to reduce "dead air" in conference recordings. Does V-Sync.Rec work the same way?

Not exactly. Unlike VCVA (Volume Controlled Voice Activation), if V-Sync.Rec doesn't detect sound at or above the pre-set volume threshold within a set time interval, it will stop recording and close the file. The interval can be set to 1 sec, 2 sec, 3 sec, 5 sec or 10 sec.

There are two V-Sync.Rec modes:

  • One Time - After failing to detect any sound and ceasing recording, the recorder closes the file and stops the recording process.
  • Continuous - After failing to to detect any sound and ceasing recording, the recorder closes the file and puts the recorder into a recording wait status. When a sound is next detected, the sound is recorded in a new file.

When I'm setting my sound levels manually, what do the Limiters and Compressors do?

The Limiters and Compressors can selectively apply enhancements to reduce clipping and improve sound recording. These enhancements are automatically applied when using the automatic sound levels, so setting the levels manually gives you more control over the final recording quality. 

Limiters and compressors can be adjusted using the Rec Level menu option in the Manual Rec Level settings.

  • Limiter 1/Compressor 1 - Select these settings to contrast high and low sounds. This option is suitable for music recording. With these settings, you can capture a lingering sound but not the attack sound.
  • Limiter 2/Compressor 2 - Select these settings to equalize the sound. This option is suitable for voice recordings. Your recording will have a consistent sound level and a sense of integrity. With these settings, you can capture an attack sound but not the lingering sound.

In Multi-Track recording, you can apply the limiters and compressors and other settings selectively for each track, to essentially engineer each track selectively in the recorder itself. It is recommended to run tests with each of the limiters and compressors to determine the effctiveness of each as applied to your recording scenarios.

What is the difference between Phantom Power and Plug-in Power?

Phantom Power and Plug-in Power refer to different methods and voltage that the recorder uses to power different types of microphones.

When the recorder uses phantom power, it sends either 48V or 24V to the left and right XLR input jacks on the bottom of the recorder. The amount of voltage is set using the Mic Power menu option. To enable phantom power, use the 48V/24V switches on the left side of the recorder.

When the recorder uses plug-in power, it sends lower current to the MIC input jack on the left side of the recorder in order to power microphones that have 3.5 mm diameter plugs.

Why does the lighted LCD screen become dimmer after a few seconds?

This is to conserve power. The Backlight setting in the menu can be used to set a longer interval before dimming the light or to change the setting to Always On.

Can I adjust the microphone sensitivity for microphones connected to the XLR jacks?

The sensitivity for all microphone audio input can be set in the Mic Gain option in the recorder's menu. The sensitivity settings available for each of the four audio inputs are:

  • Built-in Mic: Hi, Mid, Lo.
  • External Mic (3.5mm MIC jack on the left side of the recorder): Hi, Mid, Lo.
  • XLR (L): Hi, Lo.
  • XLR (R): Hi, Lo.
