The microphone and amplifier circuits have been completely redesigned to achieve superior frequency response and the maximum sound pressure level of 140dB SPL. The result is astounding, ultra high quality sound.
To get the most out of basic performance such as frequency response and directional characteristics, focus was placed on the size of the microphone casings and the shape of the openings. The left and right microphone units are placed angled outward at a 90 degrees angle to achieve a stereo sound with a natural ambience.
Optimally designed microphone chambers keep the generation of unwanted reflected sound (noise) to a minimum.
The optimally designed microphones and circuits have a wide frequency response. The result of this is a recorder with rich sound quality that excels at reproducing low frequencies, such as the sound of bass drums and bass guitars.
To transfer and amplify the sounds captured by the microphones as faithfully as possible, Olympus' design focuses on sound quality in its signal processing circuitry. The amplifier components include independent low noise and distortion amplifier signals for the left and right channels. Eliminating cross-channel interference enables clear signal transmission and achieves a high signal-to-noise (S/N) ratio. Analogue circuits, which perform delicate processing of the electric signals that affect subtle nuances in the sound, include isolated power supply circuits. This reduces the minute interference from the power supply to help improve the S/N ratio. In addition, the boards for system control (digital) and audio have been separated to prevent interference noise and achieve low-noise signal transmission.
If sound that exceeds the maximum sound pressure level of the recorder is recorded, clipping will occur even if the recording level is decreased. Therefore, measures such as moving the microphone extremely far away from the sound source have been required up until now, but a good result was not always possible depending on the recording environment. For that reason, we have made sure that the LS-100 achieves the highest maximum sound pressure level for a recorder of 140 dB SPL. This is a level that was previously unthinkable with conventional recorders. It means that the explosive sound of rock music or loud sound of drums can be recorded without clipping.
|110dB||Alto sax, piano (professional), vocal (amateur), brass instruments|
|120dB||Tenor sax, vocal (professional), live club performance, orchestra|
|130dB||Rock band concert, percussion, conga, drums, etc.|
This model comes with 24V/48V phantom power compatible XLR and standard phone combo jacks. This means that you can connect a guitar, bass, keyboard, or other musical instrument directly to the LS-100. The recorder incorporates an independent instrumentation amplifier so noise is reduced to achieve a high S/N ratio even when a very long cable is used.
When connecting a monaural device, connect it to the L combo jack. Connect a musical instrument that outputs stereo such as a keyboard to both the L and R combo jacks.
When connecting a dynamic microphone or condenser microphone, connect it to either the L or R combo jack. When phantom power is required, turn on the XLR Power switch of the XLR and standard phone combo jack to which the microphone is connected.
The recording levels can be finely adjusted even if different devices are connected to the left and right XLR.
This function automatically measures the phase distance to determine the distance between the microphones and the sound source for studio recording and other applications. You can adjust or reproduce the recording conditions by adjusting the position and orientation of the XLR microphones while checking the Lissajous waveforms.
Multitrack recording allows you to mix together multiple separately-recorded sound sources to create a single stream of sound. A class-leading maximum of eight tracks per project is possible. Now you can enjoy full-fledged song writing in an accessible format.
Multitrack recording allows you to mix together multiple, separately recorded, sound sources to create a single stream of sound. A class-leading maximum of eight tracks per project is possible. Now you can enjoy fully fledged song writing in an accessible format.
The following is an example of creating a one-person band by playing various instruments in succession and then mixing the recordings together.
Record the drums first on Track 1 to set the tempo of the performance. Connect headphones to check the exact tempo with the metronome function.
Record the bass on Track 2 while listening to the drums of Track 1. Any mistakes or corrections will not affect Track 1 so you can re-record as many times as you want.
Record the guitar on Track 3 while playing back either just Track 1 or both Track 1 and Track 2.
Record the vocals on Track 4 while playing back Track 1 to 3 that you recorded up to now. You can even record additional tracks for the sub vocals of the chorus and harmonic parts yourself.
Up to eight tracks can be mixed at the same time. All operations are possible with the screen level meters including using the mute function to turn on or off each track, using the volume controls to adjust the volume balance of parts, and using the left and right balance (pan function) to adjust the positional relationship of musical instruments, so anybody can make music they will be satisfied with.
Output up to 8 tracks to a stereo audio file.
The completed audio file can be written to a data CD in a directly connected commercially available CD drive. You can also convert the file to MP3 and then distribute it over the Internet via a PC.
While the OM-D already offers impressive audio recording capabilities, anyone who wishes to record in hifi quality should make use of an external Linear PCM audio recorder, such as the one from the Olympus LS series. Connect the Olympus OM-D E-M1/E-M5 Mark II and the Olympus LS-100 with a separately available audio cable. The LS-100 records in the highest possible audio quality while the camera captures the video images in Full HD splendor. Use the enclosed USB cable for synchronised PCM audio and video movie recording. The recorder can be easily connected to the camera hot-shoe using a separately available adapter. The LS-100 can generate a quick "slate tone," which adds a simultaneous quick tone to both the audio track on the PCM recorder and in-camera audio, making the separate audio tracks easy to sync up in post-production.
Existing recorded data can be overdubbed. While similar to the multitrack function, this is a way to enjoy overdubbing in a simpler and more direct way. For private enjoyment, you can even use sources such as music CDs to make an original recording in which you perform together with pro musicians. This is also a useful feature for karaoke-type uses, for adding sound effects such as the bustle of the city, train sounds or bird calls, and for adding subtle arrangements on top of existing data to make something original.
There is a metronome function that can be used for practicing an instrument as well as a rhythm guide during recording.
Count down / Tempo / Rhythm pattern / Sound / Volume
This function includes Calibration, Chromatic Tuner and Guitar and Bass Mode, enabling you to perform accurate tuning according to the type of instrument.
There is 4GB or internal memory and an external memory slot with support for the very versatile SD, SDHC, and SDXC (up to 64GB) cards.
Support is included for both the 96kHz/24bit linear PCM (WAV) format enabling high quality recording and playback with a dynamic range surpassing that of music CDs and the highly versatile MP3 format.
This function is for converting WAV files saved in PCM format to MP3 files with a bit rate of 128kbps. This allows you to decrease the size of large WAV files.
There is a limiter function that allows you to adjust the recording level manually. It suppresses distortion caused by sudden loud sounds. There is also a compressor function for compressing while maintaining the overall balance.
The input sensitivity can be changed to match your recording environment or intended purpose. This function supports not only manual mode but also auto mode.
You can use the low cut filter to cut the noise in two steps according to the types of noise, such as that of an air conditioner, projector, and wind.
Pre-recording is a function for continuing recording from up to two seconds before the start of recording. For example, when recording a small bird singing, this function will start recording up to two seconds before the bird starts singing if you press the recording button the moment the bird starts singing.
The playback speed can be changed between 50% and 400% without changing the pitch of playback.
You can repeatedly play back one section of the file being played.
The battery can be charged while it is still in the recorder. You can also connect the recorder to a PC via USB to charge the battery from the power supplied from the PC.
This convenient feature gives audio announcements of recorder operating conditions.
Large files or files with long recording times can be split.
You can use the dedicated remote control RS30W (sold separately) to start and stop recording remotely.
