“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
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
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 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 “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. (→ Setting the type of batteries used)
Turn off inputs that are not used. (→ Enabling tracks for recording)
Set the display to dim when not operated for a specific amount of time. (→ Setting display power saving)
Reduce the display brightness. (→ Setting the display brightness)
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)
