What are the main features of this model?

The Olympus VN-6000 digital recorder employs CELP (Code Excited Linear Prediction) technology to extend recording capacity. The three recording quality modes provide options for recording high-quality sound files or expanding memory capacity by using a lower-quality recording mode. The VN-6000 also has options for setting an alarm or configuring the recorder to automatically record unattended for a preset time period. The microphone and earphone jacks allow the use of audio accessories.

What is SubBand?

SubBand coding enables a higher-quality compression of an audio file by dividing the input audio signal into subbands of the frequency range and separately encoding each subband using psychoacoustic technology. A common example of subband encoding is the mp3 (MPEG 1 audio level III) audio format.

When an audio signal reaches the human ear, the louder frequencies with higher energy mask the lower energy frequencies, so the listener does not hear them. SubBand coding discards the inaudible lower energy frequencies from the saved digital audio file, resulting in smaller digital files that can be played back using a lower bit rate.

What is CELP?

Code Excited Linear Prediction (CELP) is an audio technology originally developed for use in cell phones. CELP works by comparing incoming sound signals to a model of human voice phonetics and saving the difference as an error report. When playing back the file, the error report is compared to the model to reconstruct the recording. The benefit is a very detailed file that employs lower bit rates and lower sampling frequencies, resulting in more efficient use of the flash memory in the recorder.

What are Index Marks?

Index Marks are digital tags that can be inserted while recording or during playback. They are used to skip forward or backward in recordings to pre-selected points. Up to 10 index marks can be added to a file. Press the [FOLDER/INDEX] button to add an index mark.

What is VCVA?

Variable Control Voice Actuator (VCVA) is a function that configures the recorder to record automatically only when sound is detected at a pre-set level and to stop when the sound drops below the threshold level. The purpose of the function is to eliminate “dead air” during recordings, thereby conserving memory and shortening file times.

VCVA is enabled via the recorder’s menu.

How much recording time is available in the VN-6000?

The length of potential recording time available in the VN-6000 is governed by the recording quality mode selected.

An HQ (High Quality) mode recording uses more memory than an LP (Long Play) quality mode recording because the HQ mode makes a more-detailed digital record than does the LP mode.

The table below shows the approximate maximum recording times possible in the VN-6000 in the different quality modes:

Quality Mode Maximum Recording Time
HQ mode Approximately 40 hours, 30 minutes
SP mode Approximately 107 hours, 55 minutes
LP mode Approximately 604 hours, 15 minutes

How is the VN-6000 turned off?

The [HOLD] switch is the recorder's ON/OFF Switch. It is recommended to set the [HOLD] switch to HOLD when replacing batteries to preserve the recorder's time and date settings.

How is the recording volume controlled?

The VN-6000 always records at 100% volume level to prevent accidentally recording with the volume set too low.

The recorder has two levels of microphone sensitivity:

  • is a low-sensitivity level used for dictation and close-up recording.
  • is a high-sensitivity level used in conference and lecture situations.

Microphone sensitivity is set in the recorder using the function.

How is the playback volume controlled?

The Playback volume is controlled using the [+] and [-] positions on the keypad on the recorder's face. Pressing [+] increases the volume. Pressing [-] decreases the volume.

Can playback speed be controlled?

Pressing the [PLAY] button during playback changes the playback speed to 75% normal speed. The icon appears on the LCD screen during slow playback. Pressing the [PLAY] button a second time changes the playback speed to 150% normal speed. The icon appears on the LCD screen during fast playback. Pressing the [STOP] button stops the playback and resets the recorder to normal playback speed.

How can I format the VN-6000?

The VN-6000 is formatted using the CLEAR function. The CLEAR function erases the time and date settings as well as the recorded files. The procedure is as follows:

  1. Hold the [STOP] and [ERASE] buttons simultaneously for three seconds or longer.
  2. Press the [] or [] button to select [YES].
  3. Press the [PLAY] button. The recorder will be formatted.

In some instances, using the [CLEAR] function will reset the recorder if it is performing erratically. Files deleted using the CLEAR function cannot be retrieved.

How does the TIMER function work?

The TIMER function enables the recorder to automatically record unattended for a preset time period. To program the recorder for timer recording, do the following:

  1. Open the recorder's menu by pressing the [DISP/MENU] button for three seconds.
  2. Using the [+] and [-] buttons on the keypad, scroll down to TIMER.
  3. SET flashes on the LCD screen. Press the [PLAY] button.
  4. Enter the recording start time. First, set the hour with the [+] or [-] button. Then press the [] button to select the minutes setting, and set the minutes using the [+] and [-] buttons.
  5. Enter the recording end time. First, set the hour with the [+] or [-] button. Then press the [] button to select the minutes setting, and set the minutes using the [+] and [-] buttons.
  6. Press the [PLAY] button to set the time.

The [HOLD] switch must be in the power ON position. The recorder will record daily during the preset time period until the TIMER function is disabled.

To disable the function, return to the TIMER function in the menu, set it to OFF and then press the [PLAY] button. This operation also deletes the start time and end time settings.

How does the ALARM function work?

The ALARM function can be set to play back an audio file at a predetermined time. This means the VN-6000 can be used for audio reminders or as a travel-alarm. An alarm setting must be attached to a particular file in a particular folder. The recorder does not have to be set to the folder being used - when the alarm time comes, the recorder will find the file.

To set an alarm:

  1. Select or record a message file to be linked to the alarm.
  2. Open the Menu by pressing the [DISP/MENU] button for three seconds.
  3. Using the [+] and [-] buttons on the keypad, scroll to the ALARM menu icon, which looks like this: .
  4. SET flashes on the LCD screen. Press the [PLAY] button.
  5. Enter the alarm time. First, set the hour with the [+] and [-] buttons. Then press the [] button to select the minutes setting, and set the minutes using the [+] and [-] buttons.
  6. Press the [PLAY] button to set the time.

When the alarm goes off, it will beep for five minutes or until any button is pressed to play the recording. The alarm will sound even if the [HOLD] switch is in the power OFF position. The alarm will sound daily until the ALARM is set to OFF.

      I am not able to record new files anymore. Why not?

      The selected destination folder and/or the recorder itself may be full. These troubleshooting tips will help you determine the cause:

      1. Press the [REC] button, and then look at the LCD screen. If the word "FULL" is displayed, the selected folder does not have enough room to record any more files. The VN-6000 has four folders, each of which can hold a maximum of 100 files.

        Press the [FOLDER/INDEX] button to switch folders. There may be room in another folder. If all of the folders are full, or if the recorder has reached its total recording time, erase some files to free space for new recordings.

      2. With the recorder idle, press the [STOP] button repeatedly and watch the LCD screen. If the remaining recording time shows 00:00, the recorder has reached its maximum recording capacity. Erase some files to free space for new recordings.

        TIP: Recording modes affect the size of audio files recorded with this product. If space is running low, switch to SP or LP recording mode to extend the amount of recording time.
