H2essential overview

Recording mode overview

With the H2essential, recording directions and mic pick up patterns can be set according to purpose.

Recording direction settings

FRONT recording

This setting records from the front of the H2essential. Use this to record with the H2essential facing the sound source.

REAR recording

This setting records from the back of the H2essential. The display can be viewed while recording your own singing while playing an instrument, for example.

FRONT+REAR recording

This setting records from both the front and rear of the H2essential. Use this when surrounded by the sound sources being recorded.

In addition to separate FRONT and REAR recording files, a mix of both FRONT and REAR can be simultaneously recorded.

Pickup pattern settings

Mono pickup pattern

When the H2essential is recording in mono, a hypercardioid pickup pattern is used. This allows the targeted sound directly in front to be recorded while suppressing sound from the sides.

90º/120º (stereo) pickup pattern

The H2essential uses the mid-side (MS) method for stereo recording.

The MS method uses a mid mic to capture sound directly forward and a side mic to capture sound from the left and right and converts these signals to stereo when recording.

In addition, by enabling MS RAW recording, mid and side audio can be recorded as is, allowing the stereo width to be adjusted afterward. (→ Recording with MS RAW format)

Recording examples

Example 1: Studio recording

During a band rehearsal, place the H2essential in the middle and record with a FRONT+REAR stereo setting to easily capture the sound of being there without worrying about mic placement.

Example 2: Face-to-face podcast recording

To capture a face-to-face podcast, place the H2essential in the middle and record with a FRONT+REAR mono setting.

In addition to the two FRONT and REAR recording files that are focused on the individual voices, a file with a clear mix of both voices will also be recorded.

In this case, the audio of the mixed file will be recorded bidirectionally.

Example 3: Recording while playing and singing

To record yourself playing and singing, place the H2essential facing toward you and record with a REAR stereo setting. This will allow you to check the waveform on the display as you record yourself playing and singing.

Example 4: Stage recording

To record facing a stage, place the H2essential in front of the stage and record with a FRONT stereo setting. This will allow the sound to be captured with wide stereo width.

In this case, by also enabling the REAR, sound with an even greater sense of being there, including the ambience of the space, can be captured.

Achieving high audio quality throughout recording and editing

With support for 32-bit float WAV files, the H2essential 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*
	Level raised		Resolution is low


*■ 32-bit float WAV*
	Level raised		Resolution is high

Clipping advantage

If a waveform sounds clipped when output from the H2essential 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.


*■ 16/24-bit WAV*
Clipped recording	Level lowered	Still clipped
	Level lowered


*■ 32-bit float WAV*
Clipped recording	Level lowered	Not clipped
	Level lowered

Appendix

Troubleshooting

If you think that the H2essential is operating strangely, check the following items first.

Recording/playback trouble

There is no sound or it is very quiet

Check the orientation of the mic or the volume settings of the connected equipment.
Confirm that the headphone volume and line output level are not too low. (→ Monitoring input sounds, Adjusting the output level when set to fixed volume control)
Plug-in power must be supplied if the mic connected to the MIC/LINE IN jack supports plug-in power. (→ Using plug-in power)
Check the volume on the Mixer Screen. (→ Adjusting the monitoring mix of the mic inputs, Adjusting the levels of mics)

Sound from connected equipment or inputs cannot be heard or is very quiet

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 the (VOLUME) dial to adjust the volume.

Recording is not possible

Confirm that the REC button 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)
Check the volume on the Mixer Screen. (→ Adjusting the monitoring mix of the mic inputs)

“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 Output menu “Volume Control” setting. To use the (VOLUME) dial 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

Use a USB cable that supports data transfer.
The operation mode must be set on the H2essential to allow the computer, smartphone or tablet to recognize it. (→ Using as an audio interface, Transferring files to computers and other devices)
Confirm that the computer, smartphone or tablet and the application being used are compatible with 32-bit float format.
Even if “H2essential” cannot be selected for the “Sound” setting on a computer, it can still be used as a 32-bit float audio interface by selecting “H2essential” as the “Audio” or “Input/Output” device in an application that supports 32-bit float format.
A driver is necessary to use 32-bit float format with Windows. The driver can be downloaded from the ZOOM website (zoomcorp.com/help/h2essential).

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

Use the latest accessibility installation file to update. (→ Installing guide sounds)
