Helix Amplify 201
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.
AMPLIFY 201 – The specialists for subwoofer performance
Uncompromising bass power in a compact format: The AMPLIFY 201 monoblock amplifiers are specifically designed for subwoofer upgrades and deliver powerful output with excellent control – ideal for deep, dynamic bass with maximum precision. With up to 750 W RMS at 1 Ohm, adjustable subsonic and lowpass filters, and phase control in the X-OVER version – or an uncompromised signal path in the DIRECT model – along with their compact footprint, the AMPLIFY 201 amplifiers are the perfect choice for targeted subwoofer upgrades in modern sound systems
