HELIX P ONE MK2

Raw power – Total control

Loads of power and tremendous stability: Our new P ONE MK2 is the ideal performance package for any subwoofer configuration. With up to 1,800 Watts RMS @ 1 Ohm, the upgrade to our powerful mono amplifier is going to rev up any woofer while always maintaining full control due to its enormous damping factor.

High-Res Audio and a fully digital signal chain

The P ONE MK2 is designed for more than just driving subwoofers. With its particularly wide frequency range up to 40 kHz and excellent signal-to-noise ratio as well as the extremely low THD, you can expect nothing less than High-Res sound quality, making it well suited for the use as a fullrange amplifier.
Due to the newly integrated optical digital input, an interference-free and ground-isolated signal transmission in the best possible quality all the way into the amplifier is now possible. The input receives signals up to a 96 kHz sampling rate lossless via light conductor and converts them back to the analog level via a cutting-edge 32-Bit BurrBrown D/A converter. Thus, the P ONE MK2 can be perfectly combined with one of our DSP amplifiers with optical digital output, for example the HELIX P SIX DSP ULTIMATE.

Extremely high power density with particularly compact dimensions

In terms of power density, the P ONE MK2 plays in a different league. No other HELIX amplifier includes so much power into such a compact package. This unique power-to-size ratio enabled by our extraordinary efficient Class D concept, which goes hand in hand with exceptionally low heat dissipation.

Features

  • High performance Class D mono amplifier with up to 1,800 Watts RMS @ 1 Ohm – a perfect match for all 2 x 2 Ohms subwoofers connected in parallel
  • High-res capability thanks to an extended audio frequency response of over 40 kHz for unsurpassed sound quality
  • Extremely high efficiency and low heat dissipation with minimal dimensions
  • High damping factor for maximum speaker control
  • Digital, optical signal input in SPDIF format including SPDIF Direct In switch for routing the digital input signal directly and losslessly to the power stage
  • BurrBrown D/A signal converter of the latest generation with a resolution of 32 Bit
  • Switchable Subsonic filter
  • Regulated power supply with Start-Stop capability for extremely stable output power even during voltage drops
  • SMD (Surface Mounted Device) manufacturing technology combines minimum space requirement with maximum reliability
  • Input Mode switch to adapt the amplifier to the input signal
  • Perfectly combinable with HELIX P SIX DSP ULTIMATE amplifier

Special features:

Fully digital

Thanks to its digital input, the HELIX P ONE MK2 enables a completely interference-free and ground-isolated signal transmission in best possible quality right into the amplifier. The input can handle digital audio signals up to a sampling rate of 96 kHz losslessly via fiber optics cable and converts them back to the analog level via a cutting-edge BurrBrown D/A converter.
But that's not all– in order to get the very last bit of performance out of the amplifier and avoid even the slightest influence of its input stage, the SPDIF Direct In function can be used to route the audio signal directly and without any detours to the output stages of the amplifier.

High-Resolution audio

The extremely wide frequency range up to 40 kHz enables lossless audio reproduction of High-Resolution audio content to provide the best possible sound in studio quality.

Signal converters with a native resolution of 32 Bit

The HELIX P ONE MK2 uses for the optical input a high-class D/A signal converter of the latest generation with a native resolution of 32 Bit instead of the common 24 Bit. The result is an unprecedented precision in signal conversion that especially optimizes the sound quality at lower signal levels.

Start-Stop capability

The switched power supply of the HELIX P ONE MK2 assures operation even if the battery’s voltage drops down to 6 Volts during engine crank.

Great Quality
Size: 8.5"X11"
This A-SUB sublimation paper is a great quality. I have been using it for many years and have had absolutely no issues. I use it with an Epson 2780 inkjet printer. I have never had a jamming issue or smudging.

Happy to find a seller that carries the 120
Size: 8.5"X11"
I’ve been doing sublimation since May 2025. I have tried a variety between 105, 120 and 125. I’m not exactly sure why 120 ASub it is becoming harder to find . I absolutely love it. When I make my stainless steel tumblers, my colors pop more with 120.

Great Sublimation Paper – Perfect for Mugs
Size: 8.5"X11"
I purchased A-SUB Sublimation Paper 8.5x11 Inch 120GSM and I’m very happy with the results. The colors transfer beautifully. I used it for sublimation mugs and the print came out vibrant, sharp, and very professional-looking. No fading, no dull colors. I also tried using it for a cap, but the issue was not the paper — my cap heat press machine didn’t perform well and the transfer failed. For mugs, this paper works perfectly. Highly recommend for mug sublimation projects.
