Troubleshooting
Restore Factory Settings
In order to revert the Ultrawave 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 FOOTSWITCH.
• Connect the power supply.
• The CONTROL LED will blink rapidly until the reset is complete. You can stop holding the
FOOTSWITCH once the CONTROL LED 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 Ultrawave 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 Ultrawave is running on the same power mains circuit as
your guitar amplifier.
Unit Appears Dead / No LEDs Lit
Wrong power supply: Use correct power supply. See the DC 9V (Power) section for more details.
Frequently Asked Questions
What kind of instruments can I connect to the Ultrawave’s inputs?
The Ultrawave’s audio inputs are high impedance (~ 1 MΩ) 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.
Can I power the Ultrawave directly over USB, without using the 9 Volt supply?
No. USB provides 5 Volts, but the Ultrawave needs 9 Volts, so the Ultrawave cannot be powered
directly from USB. Make sure that you have plugged in the included 9V DC power supply or a suitable
third party PSU when connecting to the Ultrawave USB port.
