HELIX AMPLIFY – Powerful. Clear. Consistent.
With AMPLIFY, HELIX redefines the standards for modern amplifier design: through a contemporary interpretation of classic concepts. Instead of "one-size-fits-all" solutions, AMPLIFY focuses on specialized models precisely tailored to different applications. This rigorous philosophy guarantees that each model delivers maximum performance for its intended use – while concentrating on the essentials.
The 2 Series marks the entry point into the AMPLIFY platform – and simultaneously forms its technical and sonic core. These compact Class D amplifiers combine power, a fully bridgeable multi-channel architecture, and outstanding efficiency with practical integration capabilities. Brilliant and precise highs, controlled mids, and tight, powerful bass – with sound quality and performance far exceeding expectations in its class, the 2 Series brings all facets of natural and powerful sound to every vehicle. Whether as a DIRECT, X-OVER, or DSP variant (from summer 2025): Everything is offered, from flexible 6-channel configurations for full-range applications to a powerful 1-channel subwoofer powerhouse. AMPLIFY 201 – The Specialists for Subwoofer Performance Uncompromising bass power in the smallest space: The AMPLIFY 201 monoblocks are specially designed for use as subwoofer amplifiers and deliver confident performance with high control – ideal for powerful low-frequency reproduction with maximum precision. With up to 750 W RMS at 1 ohm, adjustable subsonic and low-pass filters, and adjustable phase in the X-OVER version, or an uncompromisingly pure signal path in the DIRECT version, as well as their compact design, the AMPLIFY 201 amplifiers are the ideal choice for targeted subwoofer upgrades in modern sound systems. Sound and performance – above the standard. The AMPLIFY 2 series not only stands for perfectly tailored solutions for different applications, but also for the clear goal of exceeding expectations in its class in terms of sound and performance in each of these applications. All amplifiers in the series offer brilliant sound quality, low distortion, and outstanding signal-to-noise ratios – coupled with consistently bridgeable multi-channel outputs for maximum power and installation flexibility. The result: A series that doesn't define itself by its class, but sets new standards within it – making it the first choice for anyone seeking application-oriented performance without compromise. AMPLIFY DIRECT – Designed for use with external DSPs. The DIRECT models, thanks to their DirectDSP inputs, are specifically designed for use in signal processor-based audio systems where clean, efficient, and transparent amplification is essential. The focus on technically simple controls and high-quality components ensures trouble-free setup. By eliminating conventional input filters, the signal remains unaltered and therefore maximally clear. The high-quality gain stage with clipping LED allows for precise level adjustment, while the simplified input circuitry effectively minimizes interference and distortion. A practical stereo/mono switch for each stereo input also allows bridged operation with just one RCA signal – without any external Y-adapters. Form follows function. The design of the HELIX AMPLIFY 2 series combines modern functionality with a clean, technically sophisticated look. The compact dimensions allow for flexible installation, even in confined spaces. A removable cover conceals connections and controls, providing additional protection and creating a clean, high-quality overall impression. Matte surfaces, precise lines, and a minimalist design language create a stylish, exclusive look that blends seamlessly into any modern vehicle interior.
