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 AD converters

Conventional equipment

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.

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

Resolution is low

Volume raised

■ 32-bit float WAV

Resolution is high

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.

■ Capturing video

Audio and video can be captured simultaneously using the H6essential and a camera.

36

HINT

If the H6essential is placed directly on a table when recording using a mic capsule attached to it, reflected
sound can 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.

37

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 H6essential has been reset
