Troubleshooting
Restore Factory Settings
To revert the Atlas to its factory settings, clearing all user data, presets, expression mappings, and
changes to the MIDI mapping, use either the Neuro Mobile App or Neuro Desktop Editor and choose
the Factory Reset option in the Hardware Options menus. It is also possible to perform a factory
reset without the Neuro App by following these steps:
•
Press and hold the F
OOTSWITCH
.
•
Connect the power supply.
•
The C
ONTROL
L
ED
will blink rapidly until the reset is complete. You can stop holding the
F
OOTSWITCH
once the C
ONTROL
L
ED
starts to blink.
Noise/Hum
Power source:
Ensure that the proper power supply is being used.
Near noise source:
Move pedal away from power supplies and other equipment.
Other equipment:
Remove other effects from signal chain; see if noise persists.
Bad cables:
Swap out audio cables.
USB ground loop:
When connected to a computer using a USB cable, noise can appear in the audio
signal. This usually results from ground loop noise due to the Atlas and computer running on
separate power supplies. In the case of laptops, disconnecting the computer’s power supply and
running it on a battery can often mitigate the noise. External display monitors are often the primary
source of noise and powering down monitors can also resolve noise issues.
Ground loop with amp:
Make sure your Atlas is running on the same power mains circuit as your
guitar amplifier.

Wrong power supply:
Use correct power supply. See the

section for more details.
Frequently Asked Questions
What kind of instruments can I connect to the Atlas’s inputs?
The Atlas’s audio inputs are high impedance (~ 1 M
Ω
) and they can accept high impedance signal
sources like guitars/basses with passive pickups, as well as low impedance sources like line-level
audio circuits, guitars/basses with active pickups, electronic keyboards, or mixer outputs. The input
circuit can handle signals ranging up to 6.0 Volts, peak-to-peak.
