H1 XLR overview

Achieving high audio quality throughout recording and editing

With dual A/D converter circuits and support for 32-bit float WAV files, the H1 XLR 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 H1 XLR 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 H1 XLR 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		Resolution is high

Clipping advantage

If a waveform sounds clipped when output from the H1 XLR 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	Volume lowered	Still clipped
	Volume lowered


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

Making input settings and monitoring adjustments

When using the H1 XLR as an audio interface, input settings and monitoring adjustments can be made in the same way as when using it as a recorder.

See the references below and make input settings and monitoring adjustments.


Reference	Explanation
Using plug-in power	Make this setting when a mic that is compatible with plug-in power is connected to the MIC/LINE IN jack.
Setting phantom power	INPUT 1 and 2 support phantom power and can provide +48 V. Turn on phantom power when condenser mics that require it are connected. This can be turned on/off separately for each input.
Reducing noise (Lo Cut)	Low frequencies can be cut to reduce the sound of wind and vocal pop noises, for example. This can be set separately for each input.
Monitoring input sounds	Use headphones, for example, to monitor input sounds and adjust the volume.
Adjusting the mix of input sounds	On the Mixer Screen, the monitoring mix of all input sounds can be adjusted. Moreover, the volumes of the input sounds and their stereo mix signal can be checked with the level meters.

Making USB audio settings

When using the H1 XLR as an audio interface, settings can be made for the monitoring sound and signals sent to the computer, smartphone or tablet.

Appendix

Troubleshooting

If you think that the H1 XLR 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 fixed level)
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 phantom power settings. (→ Setting phantom power)
Check the volume on the Mixer Screen. (→ Adjusting the mix of input sounds, Adjusting the mix of input sounds)

Cannot hear sound from connected equipment/input or the volume is very low

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 (VOLUME) to adjust the volume.

Recording is not possible

Confirm that the REC indicator 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 mix of input sounds)

Recorded sound cannot be heard or is very quiet

Confirm that the input source setting is correct for the connected device. (→ Connecting input devices)

“INPUT OVERLOAD!” appears

The input sound is too loud. Increase the distance between the mic and the sound source.
Set the MIC/LINE switch to LINE.
When connecting a line-level device, adjust the volume of the device.
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 “Volume Control” output setting. To use (VOLUME) 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 H1 XLR 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.
A driver is necessary to use 32-bit float format with Windows. The driver can be downloaded from the ZOOM website (zoomcorp.com/help/h1xlr).https://zoomcorp.com/help/h1xlr
Even if “H1 XLR” cannot be selected for the “Sound” setting on a computer, it can still be used as a 32-bit float audio interface by selecting “H1 XLR” as the “Audio” or “Input/Output” device in an application that supports 32-bit float format.

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)
