We offer a $15 flat rate Australia-wide shipping service, no matter how many items, however large or heavy items may incur a higher freight charge. If your item/s is subject to additional freight charges due to being large or heavy, this will be calculated at checkout. If any damage occurs during shipping, it is the responsibility of the customer to notify us within 24 hours of the order arriving. This is a requirement of our freight insurance and we are unable to lodge any claims after 24 hours from delivery.
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.
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
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.
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.
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.
