Technologies and Components

Outstanding musicality.
Ansuz Sparkz is a noise cancellation plug for open mains sockets, mainly in power distributors. Mains power transmits disturbing noise that ‘bleeds’ into the other Hi-Fi components and impairs their ability to reproduce music with openness and fine detail on a wide soundstage. Ansuz Sparkz is equipped with Ansuz noise reduction technologies to deliver any music with more openness and speed, against an amazingly quiet background.

The Tesla coil principle

The key operating principle of the Ansuz Tesla coil is to have two coils wound in opposite directions – one coil and one counter coil. In Ansuz words, this is called “A double inverted coil”. The two coils both carry voltage, and when one of the Tesla coils encounters a voltage spike, a counter spike is activated to eliminate the noise. Since noise spikes are pure voltage carrying virtually no charge, the cancelation is quite good, but not perfect. Adding more Tesla coils in parallel, increases the noise cancellation and the perceived blackness in the music increases significantly along with the purity and clarity of the sound. Ansuz uses various types of Tesla coils, as their individual properties ideally complement and reinforce each other.

Ansuz active Tesla coil

Minimized Impedance.
The active Tesla coils are current fed, which ensures a much lower impedance and thus, a much better ability to eliminate noise. The active version is about three to four times more efficient than passive Tesla coils.

Analog Dither technology

Musical information from the depth.
Analog dither technology originated in radar, where it ensured a stronger signal and thus greater range. Ansuz adopted this technology. Their active Tesla coils send pulsating signals at precisely defined frequencies. These signals are sent in anti-phase. This significantly amplifies the musical signal and eliminates the background noise floor.

Sparkz housing – POM

The housing is casted POM which is having remarkable electrical insulating properties. The Sparkz harmonizers are designed to fit beautifully in all power outlets as well as in the Ansuz Mainz8 power distributor.
