Helix P One Mk2 (P – Series)

HELIX P ONE MK2

Raw Power Meets Total Control

The HELIX P ONE MK2 is engineered to unleash raw, clean power with total precision. Delivering up to 1,800 Watts RMS at 1 Ohm, this high-performance Class D mono amplifier is ideal for subwoofer configurations demanding extreme output without compromising control. Thanks to its exceptional damping factor, the P ONE MK2 ensures tight, accurate bass reproduction even under heavy loads, making it a top-tier solution for audiophiles and competition-grade sound systems.

High-Res Audio and Fully Digital Signal Chain

The HELIX P ONE MK2 is more than just a subwoofer amplifier—it is also built for Hi-Res full-range audio playback. With an extended frequency response that reaches beyond 40 kHz, an outstanding signal-to-noise ratio, and ultra-low THD, this amplifier guarantees studio-quality audio performance.

Adding to its sonic excellence is a newly integrated optical digital input. This enables ground-isolated, interference-free signal transmission using SPDIF format with support for up to 96 kHz sampling rates. The signal is converted back to analog with a high-end 32-bit BurrBrown D/A converter, maintaining full signal integrity throughout the chain. The SPDIF Direct In function even allows the signal to bypass pre-processing for the purest path to the output stage.

Compact Size, Massive Power Density

Despite its compact form factor, the P ONE MK2 delivers class-leading performance. Thanks to the ultra-efficient Class D topology, it offers low heat dissipation and a remarkably high power-to-size ratio, making it easy to install in tight spaces while still pushing serious wattage.

Special Features

Fully Digital Audio Transmission

The built-in optical SPDIF input ensures a fully digital, interference-free signal path directly to the amplifier. Using a 96 kHz capable digital audio stream, the HELIX P ONE MK2 converts this with a cutting-edge 32-bit BurrBrown DAC, preserving audio fidelity throughout. The SPDIF Direct In switch allows the digital signal to bypass internal circuits and reach the amplifier stage unaltered, ideal for maximum sound purity.

High-Resolution Audio Support

Designed for audiophiles, the P ONE MK2 supports high-resolution audio with a frequency response extending over 40 kHz. This makes it perfect for playing back uncompressed audio content in studio-quality sound, far beyond traditional amplifier ranges.

32-Bit Signal Processing for Maximum Precision

Where most amplifiers stop at 24-bit processing, the HELIX P ONE MK2 uses a native 32-bit D/A signal converter. This provides greater accuracy at lower signal levels and overall cleaner sound, enhancing audio detail and dynamics.

Start-Stop Capability

Modern vehicles with fuel-saving features often shut off the engine at stops, causing voltage drops. The P ONE MK2’s regulated power supply is Start-Stop capable, ensuring continuous operation even if voltage dips as low as 6 Volts during engine crank.
