Helix AMPLIFY 204 X-OVER 4-channel amplifier with integrated active crossover

With the AMPLIFY series, HELIX redefines the idea of modern amplifier design, reinterpreting classic concepts through the lens of today's audio needs. Rather than designing an amplifier to do everything, the focus is on specialized models, each of which has been conceived for a specific type of application. This clear philosophy ensures that each variant provides exactly what is needed, and nothing that is not needed.

Series 2 marks the entry into the AMPLIFY platform and constitutes its technical and tonal core. These compact Class D amplifiers combine powerful performance, a fully configurable multichannel architecture and excellent efficiency with perfect integration in the real world. Bright and precise highs, controlled mids and powerful lows: Series 2 enhances every nuance of natural and powerful sound, exceeding category expectations in both sound quality and performance. Whether it's a DIRECT, X-OVER or DSP variant (coming in summer 2025): from flexible 6-channel configurations for fullrange applications to dedicated mono units for subwoofers, Series 2 offers tailored solutions for every configuration.

AMPLIFY 204 X-OVER Features

  • Highly efficient amplifier with high output power up to 240 Watts RMS @ 2 Ohm per channel for impressive dynamics and powerful sound
  • Linkable output channels for flexible system configurations and maximum output power
  • Very compact design for space-saving installation
  • Start-stop capability down to a power supply voltage of 6 V for uninterrupted performance
  • Integrated active crossover with highpass and lowpass filters and input mode selector for optimal system configuration
  • DirectDSP function: the input signal bypasses the integrated active crossover and is routed without filters to the amplifier output stage.
  • Smart high-level input with ADEP.3 for seamless integration into OEM audio systems
  • Advanced Class D concept for high efficiency and low heat dissipation
