HELIX AMPLIFY 201 X-OVER 1-channel subwoofer amplifier extremely compact, with crossover and 1 Ohm stability

Main features

  • Highly efficient subwoofer amplifier with high output power up to 750 Watts RMS at 1 Ohm - the perfect solution for all subwoofers 2 x 2 Ohm connected in parallel
  • Ideal for boosting subwoofers in factory audio systems thanks to the integrated active crossover and high-level stereo input with high power and input sensitivity up to 32 V RMS
  • High-level input with ADEP.3 for seamless integration into OEM audio systems
  • Crossover with low-pass, subsonic and phase filter for optimal system configuration
  • Additional automatic turn-on via music signal for maximum compatibility with factory audio systems
  • Very compact design for space-saving installation
  • Start-stop functionality down to a supply voltage of 6 V for uninterrupted performance
  • Advanced Class D concept for high efficiency and low heat dissipation
  • Remote control cable for volume adjustment

With the AMPLIFY series, HELIX redefines the concept of modern amplifier design, reinterpreting classic concepts in light of today's audio needs. Rather than designing a single amplifier capable of doing everything, the focus is on specialized models, each tailored to a specific type of application. This clear philosophy ensures that each variant offers exactly what is needed - and nothing else.

AMPLIFY 201 optimizes subwoofer performance to the best

Bass power without compromise in a compact format: AMPLIFY 201 monoblock amplifiers are specifically designed to boost subwoofers and deliver high output power with excellent control - ideal for deep and dynamic bass with maximum precision. With up to 750 W RMS at 1 Ohm, adjustable subsonic and low-pass filters and phase control in the X-OVER version - or an uncompromising signal path in the DIRECT model - together with their reduced footprint, AMPLIFY 201 amplifiers represent the perfect choice for targeted subwoofer upgrades in modern audio systems.

Series 2 marks the entry into the AMPLIFY platform and constitutes its technical and sonic heart. These compact Class D amplifiers combine powerful performance, a fully bridgeable multi-channel architecture and excellent efficiency with perfect integration into the real environment.

Bright and precise highs, controlled midrange and powerful and well-defined bass: Series 2 enhances every nuance of a natural and powerful sound, exceeding the expectations of its category in both sound quality and output power. Whether it is the DIRECT, X-OVER or DSP variant: from flexible 6-channel configurations for full-range applications to powerful dedicated mono amplifiers for subwoofers, Series 2 offers tailored solutions for every configuration.
