The Helix Stadium Application

Important! The Helix Stadium application is supported on Helix Stadium family devices with firmware version 1.1.0 (or later). The Helix Stadium app supports firmware updates via USB-C connection to Stadium devices running firmware version 1.0.0 (or later). However, most other application functionality is only supported with the devices running the version 1.1.0 device firmware (or later). We highly recommend updating to the latest available firmware version and using the latest Helix Stadium application version.

Use the Helix Stadium application on your macOS or Windows® computer to connect via Wi-Fi and create, edit, backup, and restore your complete library of Stadium presets, and import and export IRs, Preset Templates, and Favorites. This page provides an overview of installation, setup, the app’s “Views,” and using the Helix Stadium application to create and edit presets.

The Helix Stadium app can also be used to perform device firmware updates via a USB connection on macOS and Windows computers. Please refer to the Stadium Firmware Updates page for details.

Importing & Exporting IR Files

Helix Stadium devices can utilize third-party Impulse Response .wav files within one or both tab locations within a Cab block, providing endless possibilities for speaker emulation. Please refer to the Cab IR section for details on using IRs. Many vendors now offer expertly captured IRs of practically any speaker and mic combination. Once you’ve purchased and saved IR .wav files to your macOS or Windows® computer, launch the Helix Stadium application and import your desired IRs into your Stadium device’s IR library.

Note: If you import several hundred IR files, the next time you power on your Helix Stadium device, it may take a few extra minutes to complete a necessary indexing process for the IR Library. Future startups of your device will not require this additional indexing time.

Importing IR Files
