H6essential overview

Achieving high audio quality throughout recording and editing

With dual A/D converter circuits and support for 32-bit float WAV files, the H6essential can maintain the highest audio quality from recording through editing in a DAW or other software.

Recording

Dual A/D converter circuits enable recording both loud and quiet sounds without making gain adjustments.

Editing with DAWs and other software

Since files are recorded using 32-bit float WAV format, audio quality can be retained when editing.

Dual A/D converter circuit overview

For each input circuit, the H6essential has two A/D converters with different input gains. This design enables high-quality audio recording without the need to adjust gain settings, a step that is normally indispensable.

Providing amazing dynamic range

By combining two A/D converters, a wide dynamic range not possible with a single A/D converter has been realized.

Switching between two A/D converters

The H6essential constantly monitors data from the two A/D converters, and automatically selects the one that provides the best recording results.

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

Clipping advantage

If a waveform sounds clipped when output from the H6essential 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.

Mic capsule overview

The H6essential includes a mic capsule (XY mic).

Characteristics

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 a three-dimensional sound with natural depth and width, this technique is ideal for recording when you want to capture a specific sound source that is nearby or at a medium distance.

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

Using timecode

Timecode overview

SMPTE timecode can be input to the H6essential by using an UltraSync BLUE made by Timecode Systems.

Timecode is time information written to data when recording video and audio. It is used for video editing, control of other devices, and synchronization of audio and video, for example.

NOTE
  • A Timecode Systems UltraSync BLUE cannot be used during audio interface operation (→ Using as an audio interface).

  • An H6essential cannot have both H6essential Control and an UltraSync BLUE connected at the same time.

Using timecode for editing

If video and audio data both have recorded timecode, aligning them to a timeline and synchronizing them together is easy when using nonlinear editing software for editing.

Appendix

Troubleshooting

If you think that the H6essential is operating strangely, check the following items first.

Recording/playback trouble

There is no sound or output is very quiet

Monitored sound is distorted

  • Use to adjust the volume.

Recording is not possible

Recorded sound cannot be heard or is very quiet

“MIC INPUT OVERLOAD!” or “INPUT 1 (2/3/4) 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 a mic, for example, when recording outdoors or when a mic is near the mouth of a speaker. (→ Reducing noise (Lo Cut))

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 H6essential 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 “H6essential” cannot be selected for the “Sound” setting on a computer, by selecting “H6essential” as the “Audio” or “Input/Output” device in an application that supports 32-bit float format, it can be used as a 32-bit float audio interface.

  • A driver is necessary to use 32-bit float format with Windows. The driver can be downloaded from the ZOOM website (zoomcorp.com).

Battery operation time is short

Making the following settings could increase the battery operation time.

An accessibility update is recommended
