HELIX P ONE MK2 | 1-Channel High-Res Amplifier with 1 Ohm Stability

HELIX P ONE MK2

Raw Power – Total Control

Power in abundance and enormous stability: Our new P ONE MK2 is the ideal powerhouse for any subwoofer configuration. With up to 1,800 watts RMS at 1 ohm, this upgrade to our powerful mono amplifier will really make any sub sweat, but thanks to its massive damping factor, it always maintains control.

High-Res Audio and a Fully Digital Signal Chain

The P ONE MK2 is designed for more than just driving subwoofers. With its exceptionally wide frequency range up to 40 kHz, excellent signal-to-noise ratio, and extremely low total harmonic distortion, it guarantees high-resolution audio quality, making it equally suitable as a powerful partner for high-power mid-bass drivers.
The new optical digital input now enables fully digital, interference-free signal transmission all the way to the amplifier. The input receives digital audio signals up to a 96 kHz sampling rate losslessly via optical fiber and converts them back to the analog domain using a latest-generation 32-bit BurrBrown D/A converter. This makes the P ONE MK2 a perfect match for one of our DSP amplifiers with an optical digital output, such as the HELIX P SIX DSP ULTIMATE.

Extremely high power density in a particularly compact design

When it comes to power density, the P ONE MK2 is in a league of its own. No other HELIX amplifier packs so much power into such a compact housing. This unique power-to-size ratio is made possible by the Class D design, which combines enormous efficiency with minimal heat generation.

Special features:

Fully digital

Thanks to the optical digital input of the HELIX P ONE MK2, completely interference-free and ground-isolated signal transmission in the best possible quality is possible all the way to the amplifier. The input receives digital audio signals up to a 96 kHz sampling rate losslessly via optical fiber and converts them back to the analog domain using a latest-generation BurrBrown D/A converter. But that's not all – to coax every last ounce of sonic performance out of the amplifier and avoid even the slightest influences from the input stage, the SPDIF Direct In function allows the audio signal to be routed directly and without detours to the amplifier's output stages. High-Resolution Audio: The extremely wide audio frequency response up to over 40 kHz enables lossless playback of high-resolution audio signals to ensure the best possible sound in studio quality. Signal Converter with Native 32-Bit Resolution: The HELIX P ONE MK2 uses a high-quality, latest-generation D/A converter in its optical signal input with a native resolution of 32 bits instead of the usual 24 bits. This results in unprecedented precision in signal conversion, which further optimizes the sound, especially at lower signal levels. Start-stop capability: The power supply in the HELIX P ONE MK2 amplifier ensures a stable internal voltage supply even during short-term drops down to 6 volts. This ensures that the amplifier remains fully functional even when the engine is started.
