V5 Syncro Uni 10

For a greater and more harmonious music reproduction, bringing reality closer to life.

The V5 Syncro Uni 10 (10 Ampere) incorporates unique DC-cancelling electronics that rebalance the mains sine wave on the zero volts line to dramatically reduce/silence transformer hum and vibration. This sophisticated product can be used independently for a single component, or in combination with another IsoTek power cleaner as an upgrade and to deliver a fully rebalanced sine wave across all output sockets.

IsoTek’s newest version of its innovative and original DC cancelling system, released almost 15 years ago upgrades the design with 60% extra current capability and corresponding reductions in impedance. The internal peak current now stands at 16 Amperes!

Features

  • Suitable for all audio-, home theater-, and network-systems, in fact all electronics.

Design

IsoTek’s newest version of its innovative and original DC cancelling system, released almost 15 years ago upgrades the design with 60% extra current capability and corresponding reductions in impedance. The internal peak current now stands at 16 Amperes!

The new V5 circuit board has been fully optimised with increased copper loading, double that of the industry standard. To further improve performance IsoTek uses a minimum of 16 capacitors, all high-grade copper/silver construction, this combined deliver a massive 75’000µF, most competitor products offer only one quarter of this with poorer grade components. All electrical parts specified within this new V5 version have been upgraded and over specified to deliver a surge protection buffer of 500 Ampere peak.

The V5 Syncro Uni is designed to dramatically reduce/silence transformer vibration and hum from the transformers within electronic equipment, generally mechanical vibration. V5 Syncro Uni can also be used as a ‘pre-filter’ device that can be used with any power cable or power distribution system.

The IsoTek V5 Syncro Uni significantly reduces unwanted direct current (DC) from the mains supply that should not be present on the mains voltage. With easy connection in and out of the product with standard or better mains power cables.

So called ‘DC on the mains’ is an increasingly common issue affecting the quality of your home’s power supply. Caused by a variety of everyday electronic devices around your home, that are connected to the power grid. These items generally run a diode electrically in series, for example, dimmer switches, hair dryers and coffee machines. But it doesn’t end there, solar panels on the roof, elevators, and fast charging stations for electric cars cause even more DC issues. These could be in your house or your neighborhood, or even further down the road. Strictly speaking the problem with DC on the mains as it is referred to, is the imbalance of the mains sine wave on the zero volts line, technically speaking it is not really a mains noise, but nevertheless bad power. It can cause considerable mechanical vibration within products (not only in amplifiers but all electronics) which will dramatically affect performance.

It is the strangest of problems on the AC line, which is a quirk of magnetic circuit design. A simple hairdryer can cause massive noise in big amplifier transformers. IsoTek has developed a series of devices called “Syncro” that incorporate unique DC-cancelling electronics that rebalance the mains sine wave on the zero volts line, to dramatically reduce/silence transformer hum; the circuit synchronizes the mains supply to provide a perfectly symmetrical sine wave, which also delivers significant improvement when used with any audio-, AV- or network electronics.

This DC current affects the performance and linearity of the power supply of electronic devices. For example, it causes the iron core of transformers to become saturated resulting in mechanical vibration and addition unnecessary heat causing transformers to physically hum. By reducing micro vibrations and heat generation, V5 Syncro Uni reduces servicing issues and increases component life. In addition, sound is significantly improved and more immediate, you hear the music and not the irregularities of mains imbalance and distortion. IsoTek’s V5 Syncro DC filter will NOT dampen dynamics! Dynamics are greatly improved because the power amplifier can draw more current when transformer saturation is reduced.

The V5 Syncro Uni 10 circuit board will run easily at 16A allowing a maximum transmission of up to 3’680W, however, to give absolute reliability and consistent performance the unit has been conservatively restricted to a standard 10A input for convenience.

Housed in a steel and aluminum chassis measuring 250mm in length, 100mm wide and 85mm high. V5 Syncro Uni incorporates unique DC-cancelling electronics that rebalance the mains sine wave on the zero volts line, to dramatically reduce/silence transformer hum and vibration; the circuit synchronizes the mains supply to provide a perfectly symmetrical sine wave, which also delivers significant sonic improvement when used with any electronic separates. The internal wiring is of the highest standard, pure 6n oxygen free copper conductor strands with silver-plating offer low resistance and high amperage. A FEP (fluorinated ethylene propylene) dielectric is used. FEP is a tough, flexible copolymer of tetrafluoroethylene and hexafluoropropylene commonly used in aerospace with excellent dielectric performance. FEP is used to protect the conductors to allow the ultimate internal power delivering system.

The internal wiring of IsoTek products synergizes with the range of IsoTek power cables. One critical but overlooked area is maintaining commonality of design and material properties though an audio wiring loom, be it signal carrying cables or your power cable network.

WEIRD feature - requires a water bottle
Color: Cow, Size: Large
Cute, but buyer beware. Maybe the description said this, but who would think to read for this.... You have to insert an empty bottle (like an old water bottle) for it to make the crinkle noise. There is a velcro spot at the base where you can open it and insert the water bottle for the noise factor and your dogs entertainment. I've yet to do that, but feel like my dog is gonna figure out the velcro and get the bottle out in no time. Seems like a waste of money. I could just give her an empty water bottle without the toy for free.

Best dog toy!
Color: Multicolor/Alligator & Wild Duck, Size: Medium, Color: Multicolor/Alligator & Wild Duck, Size: Medium
Best dog toy! Most dog toys lady maybe a week or less but this one has been going strong for almost 2 months. Both the squeekers still work on both toys i purchased. My vizsla loves ti squeek and carry it around. We added an empty water bottle in the pocket cavity for some extra fun! Yes, we are still on the same water bottle! Fantastic durability.

Shows wear quickly
Color: Multicolor/Sheep & Cow, Size: Medium
These are cute but not holding up as well as I had hoped. Quality is ok and the Velcro has held up great. The fabric just isn’t as good as it could be. They are much larger than expected.

Super Sturdy with hours of fun.
Color: Wild Duck, Hare, Squirrel & Alligator, Size: Small
I got the small ones that you cannot put a water bottle in. These toys have held up way better than expected. I am dog sitting a very rough with toys dog named Chunk. He tears up ever. Single. Toy my dog (Ted) has. I bought new ones just for chunk. These appealed to me with the no stuffing, They were cheaper, and have a squeaker. Everything chunk needed. They arrived on time and I thought I wasted my money. They were super soft, like too soft. They felt flimsy and weak. Like 5 minutes with chunk and they be dead. 2 hours with my dog and they would have a rip. So far 2 of them (I set two out) have lasted the whole weekend. The bunny looks very rough and disgusting, but no rips, the squeakers still work, and no random fluff everywhere. I am going to wash the bunny once chunk leaves. My very careful doggo Ted loves them too. He throws them up in the air and catches them, plays tug of war with them, and no rips. They are super sturdy. He can’t wait until Chunk leaves (chunk is 2 and Ted is 12-13) so he can play with them.

Loved it
Color: Brown/Wild Duck, Size: Large, Color: Brown/Wild Duck, Size: Large
He loved it so much, he destroyed it so we ordered another. I didn't realize that you can stick an empty water bottle inside. Again, the first one didn't last long, but he enjoyed it
