H1essential overview

Achieving high audio quality throughout recording and editing

With support for 32-bit float WAV files, the H1essential can maintain the highest audio quality from recording through editing in a DAW or other software.

32-bit float WAV file overview

32-bit float WAV files have the following advantages over conventional 16/24-bit WAV files.

Due to these advantages, the audio quality of recording can be maintained afterward when editing in a DAW or other software.

Resolution advantage

32-bit float WAV files have the advantage of being able to maintain high resolution even at low volumes. As a result, quiet sounds can be made louder when editing after recording without degrading their quality.

■ 16/24-bit WAV

Volume raised

Resolution is low
■ 32-bit float WAV

Volume raised

Resolution is high

Clipping advantage

If a waveform sounds clipped when output from the H1essential or in a DAW, it can be edited after recording to lower its volume and restore an unclipped waveform because the data in the 32-bit float WAV file itself is not clipped.

Making preparations

Inserting microSD cards

  1. When the power is off, open the microSD card slot cover, and insert a microSD card with the logo facing up all the way into the slot.

    To remove a microSD card, push it further into the slot and then pull it out.

  2. Close the microSD card slot cover.
    NOTE

    • Always make certain that the power is off when inserting or removing a microSD card. Inserting or removing a card while the power is on could result in data loss.

    • When inserting a microSD card, be sure to insert the correct end with the top side up.

    • Recording and playback are not possible when a microSD card is not loaded in the H1essential.

    • Always format microSD cards in order to maximize their performance after purchasing them new or using them with a different device. (→ Formatting microSD cards)

    • A message will open when a card that has not been used with the H1essential before is loaded in it.

      The SD Card Screen will be shown. Then, test the SD card. (→ Testing microSD cards)

    • The following types of recording media are supported.

      • microSDHC: 4 GB – 32 GB

      • microSDXC: 64 GB – 1 TB

Supplying power

The H1essential can operate using batteries or a power supply connected to the USB port (AC adapter, USB bus power or portable battery).

Power from a power supply connected to the USB port will be used before batteries.

Installing batteries

Use 2 AAA batteries when operating the H1essential on battery power.

  1. When the power is off, push the latch down to open the battery cover.
  2. Install 2 AAA batteries.
  3. Replace the battery cover.
NOTE

  • Use only one type of battery (alkaline, NiMH or lithium) at a time.

  • Set the type of battery used correctly so that the amount of remaining battery charge can be shown accurately. (→ Setting the type of batteries used)

  • If the batteries run out of charge, turn the power off immediately and install new batteries. The battery charge will always be shown when operating on battery power.

Connecting an AC adapter

Connect the cable of a dedicated AC adapter (AD-17) to the USB port (Type-C) and connect the adapter to an outlet.

Using other power sources

By connecting the USB port (Type-C) to a computer, the H1essential can be operated using USB bus power. Moreover, it can also be powered by a 5V portable battery (commercially-available).

Connecting input devices

Using the built-in XY microphone

The H1essential uses an XY stereo format employing two mic units oriented perpendicularly to each other.

By having left and right diaphragms face inward perpendicularly to each other, a wide recording range can be covered while fully capturing sound sources in the center.

Moreover, since the points of recording are almost the same, no phase differences occur between the left and right channels.

Providing three-dimensional sound with natural depth and width, this recording technique is ideal for capturing specific sound sources that are nearby or at medium distance.

Use examples: solo and chamber music performances, live rehearsals, field recordings, etc.

Connect a lavalier mic, for example, to the MIC/LINE IN jack

The H1essential has a MIC/LINE IN jack that can be used to connect an external mic or line-level device.

This jack can also provide plug-in power to mics that use it.

NOTE

When using the MIC/LINE IN jack, the built-in XY mic cannot also be used.

H1essential placement

If the H1essential is placed directly on a table when recording using its built-in XY mic, reflected sound could interfere with recording and reduce clarity. We recommend using a tripod, for example, to distance it from the table. Placing something like a handkerchief can also be effective in reducing sound reflected from a table.

Turning the power on/off

Turning the power on

  1. Slide toward until the display becomes active.

    After the Startup Screen is shown, the Home Screen will open on the display.

    The first time the power is turned on after purchase as well as when the H1essential has been reset to factory defaults, setting screens for the guide sound, display language and date and time will be shown.

Settings can be made for output to headphones and connected devices.

When connecting another device, minimize its input gain and use an audio cable to connect its external mic jack to the PHONE/LINE OUT jack on the H1essential.

HINT

When output to an external device is unnecessary, disconnecting the cable from the PHONE/LINE OUT jack can increase the amount of operation time when using batteries.

Changing how the output level is adjusted

How the level is adjusted for output from the PHONE/LINE OUT jack to other devices can be changed.

Appendix

Troubleshooting

If you think that the H1essential is operating strangely, check the following items first.

Recording/playback trouble

There is no sound or it is very quiet

Cannot hear sound from connected equipment/input or the volume is very low

  • Check the headphone volume.

  • If a CD player or other device is connected to the input jack, raise the output level of that device.

  • Check the input signal monitoring settings. (→ Monitoring input sounds)

Monitored sound is distorted

  • Use to adjust the volume.

Recording is not possible

  • Confirm that the REC indicator is lit red. (→ Recording)

  • Confirm that the microSD card has open space. The available recording time can be checked on screen when recording is paused. (→ Home Screen)

  • Confirm that a microSD card is loaded properly in the card slot. (→ Inserting microSD cards)

“MIC INPUT OVERLOAD!” appears

  • The input sound is too loud. Increase the distance between the mic and the sound source.

  • Wind can also cause loud noises to be input. We recommend using the Lo Cut setting to reduce noise if air is blown directly at the mic, for example, when recording outdoors or when the mic is near the mouth of a speaker. (→ Reducing noise (Lo Cut))

Output volume cannot be adjusted

  • Check the “Volume Control” output setting. To use to adjust the output volume, set it to “Knob”. When set to “Fixed”, use “Fixed Level” to adjust the volume. (→ Making output settings)

Other trouble

The recorder is not recognized by a computer, smartphone or tablet even though it is connected through the USB port

Battery operation time is short

Making the following settings could increase the battery operation time.

  • Set the type of batteries used correctly. (→ Setting the type of batteries used)

  • Reduce the display brightness. (→ Setting the display brightness)

  • Set the display to dim when not operated for a specific amount of time. (→ Setting display power saving)

  • Reduce the sample rate used to record files. (→ Setting the sample rate)

  • Disconnect unnecessary cables from the PHONE/LINE OUT jack.

  • Due to their characteristics, using nickel metal hydride batteries (especially high-capacity ones) or lithium batteries should enable longer use than alkaline batteries when power consumption is high.

An accessibility update is recommended
