Line 6 Helix Rack Multi-Effects Unit

Dial in genuine tone from the tour-ready Helix multi-effects rack unit. Program multiple signal chains with the on-board amp, cab, and effects modelers.

Helix Rack is the rack-mountable version of the flagship amp and effects processor from Line 6. The Helix Rack processor leverages dual-SHARC processing and HXTM Modeling to deliver the authentic sound and feel of vintage and modern amps, cabinets, microphones, and effects. Meanwhile, that same processing power lets you create countless tones that simply don't exist in the analog world.

The Helix Rack amp and effects processor also boasts a full-color LCD screen and ergonomically arranged controls, four independent internal signal paths, extensive analog and digital I/O including L6 LINKTM and VDI Variax connectors, a C/V output, and a BNC wordclock input for synching to studio gear. You can also load third-party speaker cabinet impulse responses (IRs) to personalize your sound. Plus, Helix Rack presets are compatible with all other Helix family devices including the Helix Native plugin.

HXTM modeling digitally mirrors the circuitry of analog amps and effects, component by component. Every model sounds and feels realistic, including such notoriously hard-to-model devices as vintage fuzz and modulation effects. Simply put, the Helix Rack amp and effects processor nails the analog vibe.

Helix Rack offers extensive I/O connectivity, routing capabilities, and MIDI integration. Its four effects sends/returns can integrate hardware pedals or pedal chains as switchable loops. They also provide additional inputs and outputs, letting read more you process multiple instruments simultaneously, as well as configure routing schemes such as wet/dry/wet and 4-Cable Method. Also included: three expression pedal/footswitch inputs, CV output, external amp switching capability, S/PDIF and AES/EBU jacks, L6 LINK connectivity, and Variax guitar and Powercab active guitar speaker system integration. This unparalleled flexibility permits integrated systems incorporating both digital and analog I/O.

The Snapshots feature lets you create up to eight variations within a single preset and seamlessly transition between them without experiencing the audio dropouts and disruption of delay and reverb trails that normally occur when switching between DSP-intensive presets. Enable and bypass effects blocks, change amp and effects settings, and much more all within the same preset.

It's easy to fine-tune your tones with the free Helix Edit software. You can drag and drop amp/effect blocks, build signal chains, and adjust parameters from your computer screen via dedicated knobs and sliders.

Helix 3.50 firmware features IR-based speaker cabinet engine and which adds 20 guitar cabs and four bass cabs with a choice of 12 microphones, and you can change their angle, position, and distance in relation to the cabs. You can even drag the mics around in space for easier and more exact placement when using the HX Edit 3.50 application.

Adding the optional Helix Control foot controller unleashes the full functionality of the Helix Rack processor. Helix Control includes capacitive-touch footswitches with color-coded LED rings and customizable scribble strips, footswitch/expression pedal inputs, and much more. No other foot controller offers these features or merges so effectively with Helix Rack.

I just received the Helix Rack yesterday so I only have a few hours in the drivers seat but that's enough to learn how truly awesome this thing is. I've owned a lot of Line 6 products over the last 20 years, in fact I still have a spider V240 and a POD HD Pro X but the Helix is so far out of their league they will probably never get used again in my studio. The design is sleek, easy to navigate, user friendly and just all around beautifully designed. The large full color screen is not only eye catching but makes navigating the menus effortless. Even though I'm modeler savvy, I've had no previous experience with Impulse Responses, in fact, I hadn't even heard of them until I started researching the Helix Rack and quite honestly I didn't think that I would care to use them... Well... I was wrong. It's amazing what these things do for the quality and authenticity of my tones when recording. As I mentioned earlier I only have 2 days under my belt at this point but most of that has been recording scratch tracks just to hear the result of these I.R's. I also love the fact that Line 6 still adds all of the necessary physical knobs and controls to their equipment in the days of everything being digital. The idea that I can play almost uninterrupted while tweaking many different parameters on the unit itself without a pedal is always a selling point for me. Not taking anything away from the foot controller but when I'm seated in front of my rack, using my hands to adjust the unit itself read more is just somewhat more convenient at times. Next, the user space... I thought that my POD HD Pro X had a lot of space for user presets but It has nothing on the Helix. I will probably never fill all of the user List's or even come close to it but It's always better to have something and not need it than to need something and not have it. Also, let me jump back to the large screen again, I have a laptop on which I keep all of my editing software for my studio equipment. I always plug in my Spider V240 and POD and use the Spider V Remote and POD HD Pro X edit software respectfully because in most cases sitting behind my recording console and tweaking my sound is just much easier to do with the computer apps than the equipment. The Helix is the first and only piece of equipment I've owned where the display is laid out and organized in a way that is very similar to a computer or tablet app and so even though I have the Helix Edit app running on my computer right next to me, making adjustments on the front of the Helix Rack in many cases is actually easier and faster than grabbing a mouse and using the comp app. I could write much more describing my total satisfaction thus far but I will wait 'till I have used it for another month or so and update my review at that time. I will leave you with this thought. While conveying my total happiness to my brother last night regarding the Helix Rack, I went so far as to say that I feel that this could be the last guitar processer I ever buy and if not it's pretty close.
