Amplify 2-Series Series - The Power To Change Perceptions
When it comes to Helix amplifiers many words spring to mind. Sleek, clean, compact, powerful, competent. Call it what you will; when talking all things power supply this tenacious German designer has absolutely every base covered. So if you're install space is at a premium, but your sound system demands plenty of power to realize its full potential; Helix's super-efficient Amplify stable of amplifiers are your absolute one stop solution. Able to deliver power in droves and sound wonderful whilst doing so, the Amplify series of powerhouses dominate everything except your bank account.

Design Ideologies
Through the entire Amplify series Helix redefines the idea of modern amplifier design; by reinterpreting classic concepts through the lens of today’s audio demands. Rather than designing one amplifier to do everything, the focus lies on specialized models; each tailored for a specific type of application. This clear philosophy ensures every variant delivers exactly what’s needed and nothing you don’t.

The Amplify 2-Series Concept
The 2-Series marks the entry into the Amplify platform, forming its technical and tonal core. These compact class D amplifiers combine powerful performance, a fully bridgeable multi-channel architecture and excellent efficiency with seamless real-world integration. Brilliant and precise treble, a controlled mid-range as well as tight, powerful bass; the 2-Series brings out every nuance of natural, powerful sound, outperforming the expectations of its class in both sound quality and output. Whether the variant is a Direct, X-Over or DSP; the Amplify 2-Series stable features everything from flexible six channel setups for full range applications down to dedicated mono powerhouses for subwoofers. The Amplify 2-Series offers tailored solutions for every configuration.

204 – The Versatile Solution For Fullrange Applications
The Amplify 2-Series 204 amplifiers combine four fully bridgeable outputs with outstanding sound quality and impressive performance, which is ideal for powerful front-end or multi-channel setups. Whether as a classic four channel system, a three channel configuration with subwoofer or a bridged two channel layout; the 204 adapts flexibly to a wide range of vehicles and system requirements. With output aplenty, it delivers more than enough power for ambitious setups. Available as an X-Over version with integrated active crossover or a Direct model optimized for pure signal transmission via external DSPs; these units always retain a focus on superior sound performance.

Sound And Power Above The Standard
The Amplify 2-Series is more than just a range of application-specific solutions. It’s a clear commitment to a very specific mission; to outperform expectations in both in sound quality and power delivery. All amplifiers in the series offer brilliant sound performance, minimal distortion and an outstanding signal-to-noise ratio. This combines with fully bridgeable multi-channel outputs for maximum output and installation flexibility. The result is a lineup that doesn’t define itself by its class but sets new benchmarks within it, making Amplify 2-Series the first choice for those seeking application-focused performance without compromise.

The X-Over Variant – Maximum Flexibility For Classic Upgrades
The X-Over models are the ideal choice for conventional sound upgrades using factory or aftermarket head units. At the heart of these models lies the integrated active crossover, featuring high-quality adjustable high-pass and low-pass filters as well as an input mode switch. This enables precise signal tuning and simplifies the implementation of various system configurations. Whether you’re running an active front system with separate tweeter and woofer channels, passive front and rear speaker setups or a combined front system with a subwoofer via bridged channels. The X-Over models provide maximum flexibility for system design. Switchable high-level and RCA inputs with up to 16 Volts input sensitivity allow seamless integration into nearly any OEM or aftermarket environment. The integrated ADEP.3 circuit ensures error-free communication with factory radios, while the automatic turn-on function reduces installation complexity. As an additional feature, the DirectDSP function allows the input signal to bypass the internal crossover entirely and be routed unfiltered to the output stage – perfect for users who plan to upgrade their system with an external DSP later on.

Form Follows Performance
The design of the Amplify 2-Series blends modern functionality with a refined, technical aesthetic. Its compact dimensions allow for flexible installation, even in tight spaces. A removable top cover conceals all connections and controls, offering additional protection as well as a clean and streamlined appearance that highlights the amplifier’s high-quality character. Matte surfaces, sharp contours and a minimalist design language create a sleek, exclusive look that integrates seamlessly into any modern vehicle interior.
