Agoura modeling: breaking new ground on emulation accuracy
The Helix Stadium series ushers in a new era of Line 6 modeling, complete with a ground-up redesign of the modeling process in the series’ revolutionary Agoura technology. While Line 6 has long utilized component-level modeling in its emulations, this innovative methodology replicates how individual components interact with the rest of the circuitry. Dubbed “Sub-component Behavioral Modeling,” Agoura re-creates ultra-minute nuances of real-world tube amp design — from the complex way that an amp’s power supply interacts with the signal to the capacitance between wire runs within the chassis.
Naturally, this technology leads to a stunning increase in emulation accuracy across the board. Moreover, while the Line 6 Helix Stadium’s amp models sport superior sound quality, Agoura modeling’s comprehensive component-level architecture also ensures that every model feels like its real-world equivalent — a far more challenging quality to capture. From the dynamic touch-sensitivity of a tube amp pushed to the brink to a quick clean-up of a dirty signal with a volume roll-off, Line 6’s Agoura modeling provides you with the precise sound and response of the most legendary gear in music history.
Capture idealized amplifier tones with Hype
While those fortunate enough to have played through a vintage Fullerton combo or a dimed British amp head may know these tones firsthand, the reality is that most musicians have only experienced these fabled sounds from their favorite recordings, after they’ve been treated and produced to mix-ready perfection. Thus, the most true-to-life model of your dream modern or vintage amplifier may not quite capture the sound of your favorite riff or solo on record. That’s where the Line 6 Helix Stadium’s Hype feature comes in. A twist of this dial transforms your tone from a component-level re-creation of the original model into the sweetened, idealized sound of a fully produced track.
Automate your sets with Showcase
The Helix Stadium’s Showcase automation and playback engine lets you do everything from jamming along with your favorite tracks to running fully automated preset and parameter changes throughout your entire performance. Need help nailing down the perfect tone for your cover band? By loading a track into your Helix Stadium, Showcase can split and mix the song’s individual instrument stems. Turn down the guitar track, and you’ll be able to play with the track itself, not on top of it. Sweetwater’s tone-sculpting enthusiasts are also quick to point out that this function is perfect for crafting stage- and studio-ready presets — the saturation-drenched lead sound you’ve so lovingly crafted might sound incredible solo, yet what sounds perfect in isolation often needs tweaking to excel in a full-band context!
Furthermore, Showcase’s power extends far beyond the boundaries of jamming and preset shaping. By placing flags at key moments within a track, Showcase can automatically trigger amp swaps, external pedal switching, MIDI to DMX lighting, drum machine and keyboard patches, and even send a message to your laptop to activate a video onstage. And for those playing in a more fluid musical setting, Showcase flags can also be activated via a footswitch stomp, giving you the power to activate your setting shifts after an unscheduled extended solo or an improvisational detour.
Streamlined touchscreen workflow
Navigating your presets and parameters is easier than ever before courtesy of the Helix Stadium’s high-resolution 8-inch touchscreen. This screen’s highly graphic-based interface seriously simplifies the process of swapping around effects blocks and modifying parameters, especially when you’re harnessing the power of the Helix Stadium’s context-based focus view. Need to quickly pull up an amp, effect, or function? Simply type in the name using the Helix Stadium’s search function for instant access. Lastly, the Helix Stadium’s grand total of 11 knobs, 13 buttons, and 12 footswitches melds this processor’s forward-thinking touchscreen controls with the instant accessibility of physical functionality.
Cloud-based cloning engine
So far, Line 6 has only hinted at the Helix Stadium’s capture capabilities, yet they were kind enough to give us a few choice details and a name: Proxy. This technology will give you the ability to clone your favorite physical amps, effects, and cabinets to add to your digital arsenal. Furthermore, as Proxy is a cloud-based technology, you’ll be free to make music with your Stadium while the cloud processes and creates your clone. To push the envelope past current cloning capabilities, Line 6 has also subtly suggested that Proxy will eventually be able to encompass gear beyond the standard amp, dirt pedal, and cabinet capabilities of most current cloners — we can’t wait to see what Proxy has in store!
Fine-tune your settings with Focus View
Boasting an intuitive graphic-based UI, Helix Stadium’s Focus View offers contextual parameter control that allows you to effortlessly shape your tones on the fly. This mode re-creates the streamlined feel of tweaking a physical amp or effect’s knobs, with straightforward explanations of what each parameter does to aid you in your tone-shaping endeavors.
Moreover, Helix Stadium’s amp and effect models also feature five customizable touch zones that can be mixed and morphed with a quick swipe. To top it all off, Preset Audition both displays information on the preset and gives you the power to play an audio clip through the preset to “audition” whether it might be the perfect pick for your track — you can even record your own clips to audition!
A more compact Stadium solution
When it comes to processing power, the Helix Stadium XL and the Helix Stadium are essentially identical. Both models boast enhanced DSP power, a dedicated GPU, a machine-learning accelerator, and FPGAs, all topped off with fresh 64-bit floating-point architecture. Even their I/O sections are essentially the same, with both models boasting internal power supplies, S/PDIF digital I/O, USB-C, and a microSD port with an included 32GB card.
So, what sets the Helix Stadium apart from its larger sibling? The Helix Stadium XL is slightly larger, sporting 12 OLED scribble strips, enhanced I/O, and a built-in expression pedal. For the musician who prefers a slightly more compact form factor — or who plans to plug in an external footswitch — the standard Helix Stadium offers all the sound and functionality of the Helix Stadium XL with a subtly streamlined setup.
Pared-down, pedalboard-ready form factor
Despite its significant increase in power, the Line 6 Helix Stadium’s optimized form factor saves considerable space on your pedalboard. At 42% smaller and nearly half the weight of the original Helix Floor, this unit makes taking your Helix rig on the road easier than ever!
Backward preset compatibility
Fear not, long-time Helix aficionados: the tried-and-true presets you’ve been rocking for 10 years of Helix history are fully compatible with the Helix Stadium. Combined with the Helix Stadium’s suite of Agoura amplifier models, you’ll be able to directly compare and audition your favorite models to find the sound that perfectly re-creates the sound in your head.
Complete cab customization
Finding the sweet spot of your amp’s cabinet emulation is a breeze thanks to Focus View's 3D graphic interface. This tool allows you to drag and drop a microphone model around your cabinet within a virtual 3D representation — it’s just like repositioning the mic around a cab in the studio, only it’s accomplished with the swipe of a finger. What’s more, the Helix Stadium’s streamlined file system can save thousands of your favorite presets and arrange them within easy-to-navigate nested folders.
