L6 overview

Realizing high audio quality while mixing

With dual A/D converter circuits and support for 32-bit float format, the L6 can maintain the highest audio quality while mixing.

NOTE

On the L6, only INPUT 1 and INPUT 2 jacks have dual A/D converter circuits.

Inputs

Dual A/D converter circuits allow input from the loudest to the quietest sounds without requiring gain adjustments.

Mixing

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

Dual A/D converter circuit overview

For each input circuit, the L6 has two A/D converters with different input gains. This design enables mixing with high quality without the need to adjust input gain, which is normally indispensable.

NOTE

On the L6, only INPUT 1 and INPUT 2 jacks have dual A/D converter circuits.

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 L6 constantly monitors data from the two A/D converters and automatically selects the one that provides the best input results.

32-bit float WAV file overview

The L6 can record input audio and mixed audio. This recorded audio is saved in a 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 after recording.

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 low


*■ 32-bit float WAV*
	Volume raised		Resolution high

Clipping advantage

If a waveform sounds clipped when output from the L6 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


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

Appendix

Troubleshooting

If you think that the L6 is 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 orientations of mics and level settings of connected equipment.
Confirm that the levels of the MASTER and MONITOR outputs are not too low. (→ Adjusting the overall and monitoring levels)
Check the levels of each channel. (→ Adjusting channel levels)
Check the phantom power setting. (→ Connecting to INPUT 1 – 2)
Check the mute setting of each channel. (→ Muting channels)

Monitored sound is distorted

Confirm that level meters are not lighting to their highest levels. If they are lighting, use the (MASTER) knob to adjust the MASTER output level.
Use the (MONITOR) knob to adjust the MONITOR level.
Confirm that (SIGNAL) indicators are not lighting red. If they are lighting, lower the levels from the connected devices and adjust the positions and orientations of mics.

Recording is not possible

Confirm that the microSD card has open space. The available recording time can be checked on the ZOOM L6 Editor screen. (→ Checking the microSD card state)
Confirm that a microSD card is loaded properly in the card slot. (→ Inserting microSD cards)

Audio files cannot be assigned to SOUND PAD buttons

Check the format of the audio file to be assigned. (→ Assigning audio files to SOUND PAD buttons)
Confirm that the audio file is saved in the correct directory. (→ Assigning audio files to SOUND PAD buttons)

SOUND PAD functions cannot be used

Check the SOUND PAD level. (→ Setting sound pad play modes and levels, Playing sound pads)
Confirm that audio files have been assigned to the sound pads. (→ Assigning audio files to SOUND PAD buttons)

Other trouble

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

Use the USB port on top of the L6 to connect a computer, smartphone or tablet.
Use a USB cable that supports data transfer.
The operation mode must be set on the L6 to allow the computer, smartphone or tablet to recognize it. (→ Transferring files to computers)
Confirm that the computer, smartphone or tablet and the application being used support 32-bit float format.
Even if the L6 cannot be selected in the computer “Sound” settings, it can be used as a 32-bit float audio interface by selecting the L6 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/l6).

Battery operation time is short

Making the following settings could increase the battery operation time.

Set the type of battery used correctly. (→ Setting the type of batteries used)
Disconnect unnecessary cables from connectors.
Due to their characteristics, using rechargeable nickel metal hydride batteries (especially high-capacity ones) or lithium batteries should enable longer use than alkaline batteries when power consumption is high.
