Zoom H4essential Operation Manual page 135

"MIC INPUT OVERLOAD!" or "INPUT 1 (2) 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

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 H4essential to allow the computer, smartphone or tablet to
recognize it. (→
Using as an audio
• Confirm that the computer, smartphone or tablet and the application being used are compatible with
32-bit float format.
• Even if "H4essential" cannot be selected for the "Sound" setting on a computer, it can still be used as
a 32-bit float audio interface by selecting "H4essential" 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).
Battery operation time is short
Making the following settings could increase the battery operation time.
• Set the type of batteries used correctly. (→
• Turn off inputs that are not used. (→
• Set the display to dim when not operated for a specific amount of time. (→
• Reduce the display brightness. (→
• Reduce the sample rate used to record files. (→
• 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. (→
