Helix Amplify 206 Direct 6 Channel Amplifier with DSP Input Bridgeable Amp

Very compact 5/6-channel amplifier with DirectDSP input “made for HELIX DSP”

The AMPLIFY 206 DIRECT expands the 2-Series with a puristic 6-channel option that covers a wide range of DSP-based applications in modern vehicles. Thanks to its fully bridgeable architecture, the amplifiers can be configured flexibly in 3-, 4-, 5- or 6-channel operation. Its high output power and compact Class-D design make it suitable for fully active 3-way front systems (in combination with a DSP) in 6-channel mode as well as classic 5-channel layouts, where channels 1–4 drive the front and rear speakers while the bridged channels 5/6 deliver up to 380 Watts RMS at 4 Ω to a dedicated subwoofer. Altogether, the 206 DIRECT provides ample performance reserves with 6 x 100 Watts RMS at 4 Ω, 6 x 190 Watts RMS at 2 Ω or 3 x 380 Watts RMS bridged at 4 Ω, making it ideal for everything from refined multi-way concepts to dynamic front/rear/subwoofer configurations.

• 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

This makes the 206 DIRECT a uniquely flexible amplifier in its class, with a clear focus on efficient and transparent power amplification. By intentionally foregoing conventional input filters, maximum signal purity is maintained, while the streamlined set of essential control elements ensures reliable, trouble-free operation. Altogether, the AMPLIFY 206 combines compact dimensions with impressive dynamics, clean headroom and excellent controllability – ideal for powerful front systems and complex OEM multi-channel architectures.

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.

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: from flexible 6-channel setups for fullrange applications to dedicated mono powerhouses for subwoofers – the 2-Series offers tailored solutions for every configuration.

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.
