FAQs
What type of power supply does the NUX A/B Roll pedal require?
The pedal requires a 9V DC power supply with a negative center and a 5.5x2.1mm DC barrel connector. The power adapter is not supplied with the pedal.
How long can I record loops for?
You can record up to 6 minutes of audio for your loops, with unlimited overdubbing capabilities.
Can I use the sub-octave and loop functions simultaneously?
Yes, the pedal is designed to allow the polyphonic sub-octave and loop recording functions to be used at the same time.
What is the purpose of the IR cab simulation?
The Integrated IR (Impulse Response) cabinet simulation helps shape your sound to mimic the tone of a real guitar or bass amplifier, which is especially useful for silent practice with headphones or for direct recording into a computer or mixer.
Can I load my own IR files onto the pedal?
Yes, the pedal features an IR loader and editor, allowing you to load custom IR files to achieve a wider range of cabinet tones.
Does the pedal support stereo output?
The NUX A/B Roll pedal features a mono output. It does not support stereo output.
How do I engage the Auto Recording mode?
The Auto Recording mode is typically engaged by playing a signal into the pedal. It will automatically start recording when it detects sound and stop when the playing ceases. Specific activation might be detailed in the full manual.
Troubleshooting
No sound output
Ensure the pedal is powered on with a correct 9V DC adapter. Check all cable connections from the instrument to the pedal and from the pedal to the amplifier/output. Verify that the 'Level' knob is turned up.
Loop recording not starting or stopping correctly
Ensure the 'Auto Recording' mode is engaged as intended. For manual control, check if there's a specific setting or footswitch function for starting/stopping. Make sure you are playing a clear signal when expecting it to record.
Sub-octave effect is weak or distorted
Adjust the 'Sub' knob to increase the level of the sub-octave. Ensure the input signal is not too hot, as this can cause distortion. The effect's clarity can depend on the instrument and playing technique.
IR simulation sounds unnatural or too quiet
Experiment with different IR modes using the '8 IR mode' switch. The 'Level' knob controls overall output; ensure it is set appropriately. The 'OTG Audio Stream' might need separate volume adjustments on the connected device.
Pedal does not power on
Verify the power supply is correctly connected (9V DC, negative center). Try a different compatible power supply or ensure the current power supply is functioning correctly. Check the pedal's power input jack for any damage.
Pros and Cons
Pros
- Adds significant depth and fullness with the sub-octave feature.
- Intuitive auto-record function simplifies loop creation.
- Built-in IR cabinet simulation provides realistic amp tones for practice and recording.
- Compact size is ideal for crowded pedalboards.
- High-quality 24-bit audio ensures clear sound.
- Versatile for practice, studio work, and live performance.
Cons
- Power adapter is not included and must be purchased separately.
- IR loader and editor software may require a learning curve for some users.
- Limited number of pre-set IR slots (7) may not satisfy all tonal preferences.
- The auto-record feature might be less suitable for players who prefer manual start/stop control.
- Sub-octave control is integrated with the 'Sub' knob, requiring careful adjustment to balance levels.
Setup, Compatibility & Care
Setup: Connect your instrument to the input and your amplifier or output device to the output. Connect a compatible 9V DC power supply (negative center, 5.5x2.1mm connector) to the power input. Adjust the 'Level' knob for overall output volume, the 'Sub' knob for the intensity of the sub-octave effect, and use the '8 IR mode' switch to select an Impulse Response cabinet simulation.
Compatibility: The pedal supports standard instrument input/output signals. It is compatible with guitars, basses, and other line-level instruments. The OTG Audio Stream support allows for connection to compatible smartphones, tablets, and computers for audio streaming.
Care: Keep the pedal clean by wiping it with a dry or slightly damp cloth. Avoid exposing it to excessive moisture, extreme temperatures, or direct sunlight. Ensure connections are secure but do not overtighten jacks. To maintain optimal performance, periodically check for dust buildup around controls and jacks.
