another world of preset sharing, deeper editing, and access to comprehensive Hardware

Options that add customization and flexibility to your pedal.

precise, in-depth changes. Use the Neuro Desktop editor to access and manage hardware
presets, customize your hardware options, and browse Neuro Community presets.

Neuro Mobile App – Now with Direct MIDI-USB Support

Comprehensive editing for your EQ2 on the go! The EQ2 is the first Source Audio pedal to
add two-way communication with the Neuro Mobile app using MIDI over USB. To connect
the EQ2 to your mobile device by USB you will need the proper cable adapters.

• iOS Devices – Any iOS device with a lightning connector is supported. A “Lightning to

USB Camera Adapter” is required. Connect the adapter to the USB A/B-mini cable that

was included with your EQ2.

• Android Devices – Android devices may have either USB-micro or USB-C connectors that

will support MIDI over USB communication with the EQ2. You will need the appropriate
USB B/C (male) to USB A (female) adapter to use with the included USB A/B-mini cable.
Note that the USB B-micro to USB A adapter is sometimes called an OTG (On-The-Go)

adapter.
Neuro Mobile App one-way communication is also supported on the EQ2. Use your device’s
headphone jack and included TRS cable to connect to Input 2 on your EQ2.
