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.

Easy to use. Stays sealed. Stays charged.
Size: 12 Combo Travel Size
I had previously bought packing bags in a store — the kind the you had to seal and then roll/squish the air out of one end of the bag. It really took 2 people to remove most of the air. I took them to Mexico, and they were just OK. I switched to these vacuum bags before our family ski trip. What a great purchase! This set includes multiple sizes, which worked well for both everyday clothes and bulkier cold-weather gear. They also fit well inside different size suitcases. One tip: Fill the bag, seal it shut, squish some air out, but then suck the final air out with the bag already inside your suitcase. You can "massage" the clothes and guide how the bag flattens out for a really efficient use of your suitcase space. The organization you can achieve is really impressive. The bag material and valve is tough enough to not allow any air leaks. The red "glides" they provide make sure the seal is solid and easy to achieve. And the system is simple enough that I suspect that elementary kids or people with lower dexterity could operate it (my teens certainly had no issues packing themselves). After returning home, I folded all the bag along their original fold lines, charged up the "sucky thing" (which still held 75% of it's charge after being used at least 20 times), and tucked it all neatly in our travel drawer, ready for our international trip next month. Great value. High quality. I'd even go so far as to say they're fun to use.

Travel bags
Size: 12 Combo Travel Size
Perfect packing bags. I’m using them for a trip to Alaska. The pump works easily . I tested them out and the air retention is perfect.? They are not too thick and will not take up space. The material seems like it will hold up without ripping. I will be using them often. They come in different sizes which work perfectly with different items.

These are a travel must!
Size: 15 Combo Travel Size
We recently took a trip to Japan and South Korea with our 3 kids, and needed to bring all their clothes for 2 weeks, with as few suitcases as possible. These bags were a life saver! We were able to fit so much more stuff in our suitcases with these bags. I don’t know how we would have brought everything without them. We would have had to bring at least one, probably two suitcases more. Easy to use - the vacuum is compact so you can bring it with you, but super powerful and works quickly. Remember to charge it after you use it for when you pack back up. But, you can manually push out the air as well if you’re in a pinch.

More pros than cons, very convenient, but durability is an issue.
Size: 15 Combo Travel Size
Pros: I think that this is a good product. I've had it for several weeks and travel every week for work. It's a good design and the vacuum pump is ergonomic and reliable, in my experience. Charges relatively quickly at home and I'm not sure how long the charge lasts, because it's convenient with a USB-C port, so I charged whenever the charge got to 3 bars. My experience is that dress shirts maintain the pressing if folded and packed neatly. They're creased, but hang them in the hotel bathroom and the steam from a shower loosens the wrinkles nicely. Cons: durability. The bags are pretty thin and after 3 or 4 trips the seal in the bag(s) can become compromised. I suspect the leaks are tiny and in the actual bag vs. the seal. With regular use, this was in only two of the fifteen bags. The double zip lock is really durable. FOR CAMPING: they were great for motorcycle camping, however the durability became an issue. I was camping along a lake and took some care with the bags, but admittedly was a little harder on them than I could have been. I took extra bags just in case, and am glad I did. Three of the 6 bags I took slowly lost the vacuum. If you're using them for camping, pack extras. They're inexpensive enough to continue to buy replacements periodically and you do get a lot. TIPS: pack the vacuum in the suitcase with the bags. Pack the bags with a complete outfit for each day. The temptation is to pack shirts in one bag, socks/underwear in the other, etc. It's more difficult to repack dirty clothes that way, but if you have each day in its own bag you just use each one for a dirty laundry bag.

Over packer approved! GOODBYE checked bag fees!!
Size: 9 Combo Travel Size
These were incredible for our recent flight to Tampa. I’m an overpacker by nature, and we normally have to check at least one bag, but these completely changed that. We were able to fit everything into our carry-ons and backpacks with room to spare, which even saved us from paying a checked bag fee. The vacuum came already charged, and I still haven’t needed to recharge it, which was a nice bonus. It also comes with a small travel bag to keep the charging cord together, which made it easy to stay organized. The suction is strong and works quickly. I packed one bag completely full and it compressed it down to about half the size. The bags are durable and easy to seal, even without using the plastic zipper clips. As long as they’re fully sealed, they stay compressed and don’t slowly let air back in. We unpacked everything at the hotel and stored the empty bags in our suitcases, then reused them to pack for the trip home with no issues. The vacuum isn’t silent, but it’s not overly loud either. I’d compare it to being quieter than a typical hair dryer. This is such a game changer for travel and saving space. I’ll definitely be using these for every trip.
