HELIX AMPLIFY 204 DIRECT - AC20410
Very compact 4-channel amplifier with DirectDSP input “made for HELIX DSP”
HELIX AMPLIFY – Power. Clarity. Purpose.
With the 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.

Highly efficient amplifier with high output power of up to 240 Watts RMS @ 2 Ohms per channel for impressive dynamics and powerful sound

Bridgeable output channels for flexible system configurations and maximum power output

Very compact design for space-saving installation

Start-stop capability down to 6V supply voltage for uninterrupted performance

Clipping LED for easy and fast gain adjustment

Designed for HELIX DSP – DirectDSP input perfectly tuned for maximum signal quality and performance

Advanced Class D concept for high efficiency and low heat dissipation

The 2-Series marks the entry into the AMPLIFY platform – and forms 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 as a DIRECT, X-OVER, or DSP variant (coming in summer 2025): from flexible 6-channel setups for fullrange applications to dedicated mono powerhouses for subwoofers – the 2-Series offers tailored solutions for every configuration.
AMPLIFY 204 – The versatile solution for fullrange applications
The AMPLIFY 204 amplifiers combine four fully bridgeable outputs with outstanding sound quality and impressive performance – ideal for powerful front-end or multi-channel setups. Whether as a classic 4-channel system, a 3-channel configuration with subwoofer, or a bridged 2-channel layout: the 204 adapts flexibly to a wide range of vehicles and system requirements. With an output of 4 x 100 watts RMS at 4 Ω, 4 x 190 watts RMS at 2 Ω, or 2 x 380 watts RMS bridged at 4 Ω, 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 – always with 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 each of those applications – 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 – combined with fully bridgeable multi-channel outputs for maximum output and installation flexibility. The result: a lineup that doesn’t define itself by its class, but sets new benchmarks within it – making AMPLIFY the first choice for those seeking application-focused performance without compromise.
AMPLIFY DIRECT – Made for external DSPs
The DIRECT models, featuring their DirectDSP inputs, are purpose-built for use in DSP-based audio systems that demand clean, efficient and transparent amplification. Especially due to the focus on essential control elements and core components, flawless operation is ensured. By eliminating conventional input filtering, they ensure uncompromised signal integrity and maximum clarity throughout the signal path. A high-quality gain stage and clipping LED enable precise level adjustment, while the minimalist input architecture keeps noise and distortion to an absolute minimum. A practical stereo/mono switch for each stereo input also allows bridged operation with just a single RCA signal – eliminating the need for external Y-adapters.
Form follows performance
The design of the HELIX 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.
