L12next overview

Combining the convenience of digital with the usability of analog

Analog mixers have dedicated knobs for every channel, enabling quick intuitive operation but they cannot save and recall scenes (settings).

On the other hand, many digital mixers can save and recall scenes (settings), but knobs are shared, so channels must be selected before making adjustments.

The L12next combines the convenience of digital with the usability of analog. For each channel strip, it has 3 knobs along with a channel knob selection button that allows their functions to be chosen instantly.

Realizing high audio quality while mixing

Input sounds are processed using 32-bit float format, so the audio quality at input is maintained while mixing.

In addition, the L12next can record mixed stereo files in 32-bit float format. This allows high sound quality to be retained during post-editing.

32-bit float WAV file overview

Master files that are recorded as stereo mixes by the L12next are saved using 32-bit float WAV file format. 32-bit float WAV files have the following advantages over conventional 16/24-bit WAV files. These advantages allow the recording audio quality to be preserved even when editing in a DAW or other software.

Clipping advantage

If a waveform sounds clipped when output from the L12next 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	Level lowered	Still clipped


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

Troubleshooting

If the L12next seems to be operating strangely, check the following items first.

Mixing/recording/playback trouble

There is no sound or output is very quiet

Confirm connections with all jacks. (→ Making connections)
Check the gain settings and mic orientations as well as the level settings of connected equipment. (→ Adjusting channel gain, using compression and reducing noise (low cut))
Confirm that the levels of the MASTER and MONITOR outputs are not too low. (→ Adjusting the overall volume, Making MONITOR OUT (A–D) jack settings)
Check the levels of each channel. (→ Adjusting channel levels)
Check the phantom power setting. (→ Connecting mics)
Check the channel and master mute settings. (→ Muting channels)
When using a passive guitar or bass, connect it to a MIC/LINE input jack (1 or 2) and turn on. (→ Connecting guitars and basses)

Monitored sound is distorted

Confirm that the highest segments of the level meters are not lighting. If they are lighting, use the channel and master faders to adjust their levels. (→ Adjusting channel levels, Adjusting the overall volume)
Use the (MONITOR OUT A–D) and (MONITOR OUT PHONES) knobs to adjust monitoring volumes. (→ Making MONITOR OUT (A–D) jack settings)
Confirm that (signal) indicators are not lighting red. If they are lighting, adjust the gain (Adjusting channel gain, using compression and reducing noise (low cut)), reduce the levels of connected equipment, and adjust the positions and orientations of mics.

There is no monitoring sound or it is very quiet

Confirm the mixes of each output. (→ Adjusting the SEND A–E mixes)
Check the monitoring volumes and switch settings. (→Making MONITOR OUT (A–D) jack settings)

Recording is not possible

Confirm that the microSD card has open space.
Confirm that a microSD card is loaded properly in the card slot. (→ Inserting microSD cards)
When in overdubbing mode, confirm that the channel select button is lit red.
If project protection is on, turn it off. (→ Protecting projects)

“Write Error” appears and recording is not possible / stopping recording takes too much time

microSD cards can become worn out. Speed can decrease after repeated writing and erasing.
Formatting the card with the L12next might improve this. (→ Formatting microSD cards)
If formatting a microSD card does not improve this, we recommend replacing the card. Please check the list of cards that have been confirmed to work on the ZOOM website.

NOTE

This is not a guarantee of specific recording performance for microSDHC/SDXC cards that have been confirmed to work. This list is provided as a guide to help find suitable cards.

Playback sound cannot be heard or is quiet

When in overdubbing mode, confirm that the channel select button is lit green.
Raise the faders on the playback channels, and confirm that the level meters are lit.

Internal effects are not working

Raise the EFX RETURN fader and confirm that the level meters are lighting.
Check the mute setting of the Send effect section.
Check the levels sent from each channel to the internal effect. (→ Using internal effects)

There is no sound or output is very quiet from MONITOR OUT A–E

Confirm the mixes of each output. (→ Adjusting the SEND A–E mixes)
Confirm that the output volume of each output is raised (MONITOR OUT A–D and PHONES knobs). (→ Making MONITOR OUT (A–D) jack settings, Making MONITOR OUT (PHONES) jack settings）
Check the MONITOR OUT A–D and PHONES output switch settings. (→ Making MONITOR OUT (A–D) jack settings, Making MONITOR OUT (PHONES) jack settings）

Audio interface trouble

Sound skips during playback or recording

If the audio buffer size of the software being used can be adjusted, increase the buffer size.
Connect the L12next directly to a USB port on the computer. Do not connect it through a USB hub.
Turn the automatic sleep function and other computer power saving settings off.

Cannot play or record

Confirm that the L12next is connected to the computer correctly.
Confirm that the Sound setting of the computer being used is set to "ZOOM L12next".
Confirm that the L12next is selected for input and output in the software being used.
Confirm that the (USB AUDIO RETURN 1-2) or (USB AUDIO RETURN 3-4) button is lit red and the level meters are lit. (→ Inputting audio output from a computer, smartphone or tablet on channels 9/10 and 11/12)
Quit all the software that is using the L12next, and disconnect and reconnect the USB cable connected to it.

Other trouble

Not recognized by a computer, smartphone or tablet even though the USB port is connected to it

Use a USB cable that supports data transfer.
The operation mode must be set on the L12next to allow the computer, smartphone or tablet to recognize it. (→ Transferring files to computers and other devices)
Even if “L12next” cannot be selected for the “Sound” setting on a computer, it can still be used as a 32-bit float audio interface by selecting “L12next” 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/help/l12next).https://zoomcorp.com/help/l12next
